Sonic Design - Explorations Between Art and Science (Springer 2024)

This edited volume is based on a selection of contributions at an international seminar organized in May 2022 to celebrate the achievements of Professor God?y upon his retirement from the University of Oslo. The 17 chapters cover different approaches to sonic design practice and theory, giving readers historical backdrops and an overview of the current state of both artistic and scientific research in the field.

Sound Actions: Conceptualizing Musical Instruments (MIT Press, 2022)

What is a musical instrument? How do new technologies change how we perform and perceive music? What happens when composers build instruments, performers write code, perceivers become producers, and instruments play themselves? The answers to these pivotal questions entail a meeting point between interactive music technology and embodied music cognition, what author Alexander Refsum Jensenius calls ¡°embodied music technology.¡± Moving between objective description and subjective narrative of his own musical experiences, Jensenius explores why music makes people move, how the human body can be used in musical interaction, and how new technologies allow for active musical experiences. The development of new music technologies, he demonstrates, has fundamentally changed how music is performed and perceived.

  In his seminal book ¡°Embodied Music Cognition and Mediation Technology¡±, Marc Leman Leman (2008a) drew up a theoretical framework that has influenced a whole new generation of researchers, myself included. Building on a long tradition of systematic musicology, combined with ecological psychology and modern technology, he convincingly set the direction for a fresh approach to scientific studies of musical experiences. In the following, I will reflect on some concepts that he raised in his discussion, and I will point out some that he left for others, like me, to explore in more detail.

  Parameter Mapping (PM) is probably the most used design approach in sonification. However, the relationship between a synthesizer¡¯s input parameters and the perceptual distribution of its output sounds might not be proportional, limiting its ability to convey relationships within the source data in the sound. This study evaluates a basic Frequency Modulation (FM) synthesis module with perceptually motivated descriptors, measures of spectral energy distribution, and latent embeddings of pre-trained audio representation models. We demonstrate how these metrics do not indicate straightforward relationships between synthesis parameters and perceived sound. This is done using interactive audiovisual scatter plots¡ªSynth Maps¡ªthat can be used to explore the sound distribution of the synthesizer and qualitatively evaluate how well the different representations align with human perception. Link to the code and the interactive Synth Maps are available.

  This paper reports on a desktop investigation and a lab experiment comparing the video recording capabilities of four commercially available 360-degree cameras: GoPro MAX, Insta360 X3, Garmin VIRB 360, and Ricoh Theta S. The four cameras all use different recording formats and settings and have varying video quality and software support. This makes it difficult to conduct analyses and compare between devices. We have implemented new functions in the Musical Gestures Toolbox (MGT) for reading and merging files from the different platforms. Using the capabilities of FFmpeg, we have also made a new function for converting between different 360-degree video projections and formats. This allows (music) researchers to exploit 360-degree video recordings using regular video-based analysis pipelines.

  This chapter presents a pedagogical approach based on the author¡¯s experience teaching interactive music technology design from an embodied music cognition perspective. The ¡°musicking quadrant¡± is introduced as a framework to understand the experiences of those who make music in real-time (performers) and non-real-time (instrument makers, composers, producers), and those who experience music in real-time (perceivers) and non-real-time (analysts). New technologies challenge these roles and allow for new types of musical engagement that align with the 4E cognition perspectives.

  The paper presents a study of the noise level of accelerometer data from a mobile phone compared to three commercially available IMU-based devices (AX3, Equivital, and Movesense) and a marker-based infrared motion capture system (Qualisys). The sensors are compared in static positions and for measuring human micromotion, with larger motion sequences as reference. The measurements show that all but one of the IMU-based devices capture motion with an accuracy and precision that is far below human micromotion. However, their data and representations differ, so care should be taken when comparing data between devices.

  In this paper, we reflect on the focus of ¡°newness¡± in NIME research and practice and argue that there is a missing O (for ¡°Old¡±) in framing our academic discourse. A systematic review of the last year¡¯s conference proceedings reveals that most papers do, indeed, present new instruments, interfaces, or pieces of technology. Comparably few papers focus on the prolongation of existing NIMEs. Our meta-analysis identifies four main categories from these papers: (1) reuse, (2) update, (3) complement, and (4) long-term engagement. We discuss how focusing more on these four types of NIME development and engagement can be seen as an approach to increase sustainability.

  ZRob is a robotic system designed for playing a snare drum. The robot is constructed with a passive flexible spring-based joint inspired by the human hand. This paper describes a study exploring rhythmic patterns by exploiting the chaotic dynamics of two ZRobs. In the experiment, we explored the control configurations of each arm by trying to create un- predictable patterns. Over 200 samples have been recorded and analyzed. We show how the chaotic dynamics of ZRob can be used for creating new drumming patterns.

  How does it feel to stand still in silence with others for 10 minutes at a time? The current chapter reports on a study of a small group of musicians and dancers that used standstill as their regular "warm-up" activity over a year of working together. Motion capture data of the sessions reveal that each individual's quantity of motion remained similar over time, but self-reports indicate that the subjective experience of time and space changed radically. The participants developed a high spatiotemporal sensitivity and reported an increase in well-being after a year of standstill. They also reported that a 10-minute standstill helped with the mental preparation before both micromotion and regular performances.

Mapping Monophonic MIDI Tracks to Vibrotactile Stimuli Using Tactile Illusions. In Saitis, Charalampos; Farkhatdinov, Ildar & Papetti, Stefano (Ed.), Haptic and Audio Interaction Design. Springer Nature. ISSN 978-3-031-15019-7. Show summary

  In this project, we propose an algorithm to convert musical features and structures extracted from monophonic MIDI files to tactile illusions. Mapping music to vibrotactile stimuli is a challenging process since the perceptible frequency range of the skin is lower than that of the auditory system, which may cause the loss of some musical features. Moreover, current proposed models do not warrant the correspondence between the emotional response to music and the vibrotactile version of it. We propose to use tactile illusions as an additional resource to convey more meaningful vibrotactile stimuli. Tactile illusions enable us to add dynamics to vibrotactile stimuli in the form of movement, changes of direction, and localization. The suggested algorithm converts monophonic MIDI files into arrangements of two tactile illusions: ¡°phantom motion¡± and ¡°funneling¡±. The validation of the rendered material consisted of presenting the audio rendered from MIDI files to participants and then adding the vibrotactile component to it. The arrangement of tactile illusions was also evaluated alone. Results suggest that the arrangement of tactile illusions evokes more positive emotions than negative ones. This arrangement was also perceived as more agreeable and stimulating than the original audio. Although musical features such as rhythm, tempo, and melody were mostly recognized in the arrangement of tactile illusions, it provoked a different emotional response from that of the original audio.

  We report on an experiment in which nine Norwegian national team rowers (one female) were tested on a rowing ergometer in a motion capture lab. After the warm-up, all participants rowed in a neutral condition for three minutes, without any instructions. Then they rowed in two conditions (three minutes each), with a counterbalanced order: (1) a coaching condition, during which they received oral instructions from a national team coach, and (2) a sound condition, during which they listened to a pre-recorded sound file that was produced to promote good rowing technique. Performance was measured in terms of distance traveled, and subjective responses were measured via a questionnaire inquiring participants about how useful the two interventions were for rowing efficiency. The results showed no significant difference between the two conditions of main interest¨Cthe pre-recorded sound file and traditional coaching¨Con any measure. Our study indicates that auditory guidance can be a cost-efficient supplement to athletes¡¯ training, even at higher levels.

  This paper describes the design and construction of a mini acoustic chamber using low-cost materials. The primary purpose is to provide an acoustically treated environment for small-scale sound measurements and experiments using ¡Ü 10-inch speakers. Testing with different types of speakers showed frequency responses of <?10?dB peak-to-peak (except the ¡±boxiness¡± range below 900?Hz), and the acoustic insulation (soundproofing) of the chamber is highly efficient (approximately 20?dB?SPL in reduction). Therefore, it provides a significant advantage in conducting experiments requiring a small room with consistent frequency response and preventing unwanted noise and hearing damage. Additionally, using a cost-effective and compact acoustic chamber gives flexibility when characterizing a small-scale setup and sound stimuli used in experiments.

  This paper describes the development of two musical instrument prototypes developed to explore how non-haptic music technologies can be accessed from a web browser and how they can offer accessibility for people with low fine motor skills. Two approaches to browser-based motion capture were developed and tested during an iterative design process. This was followed by observational studies of two user groups: one with low fine motor skills and one with normal motor skills. Contrary to our expectations, we found that avoiding the use of buttons and mice did not make the apps more accessible for the participants with low fine motor skills. Furthermore, motion speed was considered more important for people with low motor skills than the size of the control action. The most important finding is that browser-based musical instruments using sensor-based and video-based motion tracking are not only feasible but allow for reaching much larger groups of people than previously possible. This may ultimately lead to both more personalized and accessible musical experiences.

  We present a proof of concept by using the mobile application MusicLab to measure motion during a livestreamed concert and examining its relation to musical features. With the MusicLab App, participants¡¯ own smartphones¡¯ inertial measurement unit (IMU) sensors can be leveraged to record their motion and their subjective experiences collected through survey responses. The MusicLab Lockdown Rave was an Algorave (live-coded dance music) livestreamed concert featuring prolific performers Renick Bell and Khoparzi. They livestreamed for an international audience who wore their smartphones with the MusicLab App while they listened/danced to the performances. From their acceleration, we computed quantity of motion and compared it to musical features that have previously been associated with music-related motion, namely pulse clarity and low and high spectral flux. By encountering challenges and implementing improvements, the MusicLab App has become a useful tool for researching music-related motion.

  Intelligent robots aimed for performing music and playing musical instruments have been developed in recent years. With the advancements in artificial intelligence and robotic systems, new capabilities have been explored in this field. One major aspect of musical robots that can lead to the emergence of creative results is the ability to learn skills autonomously. To make it feasible, it is important to make the robot utilize its maximum potential and mechanical capabilities to play a musical instrument. Furthermore, the robot needs to find the musical possibilities based on the physical properties of the instrument to provide satisfying results. In this work, we introduce a drum robot with certain mechanical specifications and analyze the capabilities of the robot according to the drumming sound results of the robot. The robot has two degrees of freedom, actuated by one quasi direct-drive servo motor. The gripper of the robot features a flexible joint with passive springs which adds complexity to the movements of the drumstick. In a basic experiment, we have looked at the drum roll performance by the robot while changing a few control variables such as frequency and amplitude of the motion. Both single-stroke and double-stroke drum rolls can be performed by the robot by changing the control variables. The effect of the flexible gripper on the drumming results of the robot is the main focus of this study. Additionally, we have divided the control space according to the type of drum rolls. The results of this experiment lay the groundwork for developing an intelligent algorithm for the robot to learn musical patterns by interacting with the drum.

  There have been several studies investigating whether musical sound can be used as cell stimuli in recent years. We systematically searched publications to get an overview of studies that have used audible sound played through speaker-based systems to induce mechanical perturbation in cell cultures. A total of 12 studies were identified. We focused on the experimental setups, the sounds that were used as stimuli, and relevant biological outcomes. The studies are categorized into simple and complex sounds depending on the type of sound employed. Some of the promising effects reported were enhanced cell migration, proliferation, colony formation, and differentiation ability. However, there are significant differences in methodologies and cell type-specific outcomes, which made it difficult to find a systematic pattern in the results. We suggest that future experiments should consider using: (1) a more controlled acoustic environment, (2) standardized sound and noise measurement methods, and (3) a more comprehensive range of controlled sound parameters as cellular stimuli.

  The topic of gesture has received growing attention among music researchers over recent decades. Some of this research has been summarized in anthologies on "musical gestures", such as those by Gritten and King (2006), God?y and Leman (2010), and Gritten and King (2011). There have also been a couple of articles reviewing how the term gesture has been used in various music-related disciplines (and beyond), including those by Cadoz and Wanderley (2000) and Jensenius et al. (2010). Much empirical work has been performed since these reviews were written, aided by better motion capture technologies, new machine learning techniques, and a heightened awareness of the topic. Still there are a number of open questions as to the role of gestures in music performance in general, and in ensemble performance in particular. This chapter aims to clarify some of the basic terminology of music-related body motion, and draw up some perspectives of how one can think about gestures in ensemble performance. This is, obviously, only one way of looking at the very multifaceted concept of gesture, but it may lead to further interest in this exciting and complex research domain.

  Music researchers work with increasingly large and complex data sets. There are few established data handling practices in the field and several conceptual, technological, and practical challenges. Furthermore, many music researchers are not equipped for (or interested in) the craft of data storage, curation, and archiving. This paper discusses some of the particular challenges that empirical music researchers face when working towards Open Research practices: handling (1) (multi)media files, (2) privacy, and (3) copyright issues. These are exemplified through MusicLab, an event series focused on fostering openness in music research. It is argued that the "best practice" suggested by the FAIR principles is too demanding in many cases, but "good enough practice" may be within reach for many. A four-layer data handling "recipe" is suggested as concrete advice for achieving "good enough practice" in empirical music research.

  The paper presents the Musical Gestures Toolbox (MGT) for Python, a collection of modules targeted at researchers working with video recordings. The toolbox includes video visualization techniques such as creating motion videos, motion history images, and motiongrams. These visualizations allow for studying video recordings from different temporal and spatial perspectives. The toolbox also includes basic computer vision methods, and it is designed to integrate well with audio analysis toolboxes. The MGT was initially developed to analyze music-related body motion (of musicians, dancers, and perceivers) but is equally helpful for other disciplines working with video recordings of humans, such as linguistics, pedagogy, psychology, and medicine.

  Ensemble musicians engage with each other visually through glances and body motion. We conducted a case study to test how string quartet musicians would respond to playing conditions that were meant to discourage or promote visually communicative behaviour. A quartet performed in different seating configurations under rehearsal and concert conditions. Quantity of head motion was reduced when musicians¡¯ gaze was constrained. Differences in gaze and body motion between musicians reflected their musical roles in the ensemble. Overall, our findings suggest that gaze and motion dynamics vary within and between performances in response to changing musical, situational and social factors.

  Music performance can be cognitively and physically demanding. These demands vary across the course of a performance as the content of the music changes. More demanding passages require performers to focus their attention more intensity, or expend greater ¡°mental effort.¡± To date, it remains unclear what effect different cognitive-motor demands have on performers' mental effort. It is likewise unclear how fluctuations in mental effort compare between performers and perceivers of the same music. We used pupillometry to examine the effects of different cognitive-motor demands on the mental effort used by performers and perceivers of classical string quartet music. We collected pupillometry, motion capture, and audio-video recordings of a string quartet as they performed a rehearsal and concert (for live audience) in our lab. We then collected pupillometry data from a remote sample of musically-trained listeners, who heard the audio recordings (without video) that we captured during the concert. We used a modelling approach to assess the effects of performers' bodily effort (head and arm motion; sound level; performers' ratings of technical difficulty), musical complexity (performers' ratings of harmonic complexity; a score-based measure of harmonic tension), and expressive difficulty (performers' ratings of expressive difficulty) on performers' and listeners' pupil diameters. Our results show stimulating effects of bodily effort and expressive difficulty on performers' pupil diameters, and stimulating effects of expressive difficulty on listeners' pupil diameters. We also observed negative effects of musical complexity on both performers and listeners, and negative effects of performers' bodily effort on listeners, which we suggest may reflect the complex relationships that these features share with other aspects of musical structure. Looking across the concert, we found that both of the quartet violinists (who exchanged places halfway through the concert) showed more dilated pupils during their turns as 1st violinist than when playing as 2nd violinist, suggesting that they experienced greater arousal when ¡°leading¡± the quartet in the 1st violin role. This study shows how eye tracking and motion capture technologies can be used in combination in an ecological setting to investigate cognitive processing in music performance.

  This paper addresses environmental issues around NIME research and practice. We discuss the formulation of an environmental statement for the conference as well as the initiation of a NIME Eco Wiki containing information on environmental concerns related to the creation of new musical instruments. We outline a number of these concerns and, by systematically reviewing the proceedings of all previous NIME conferences, identify a general lack of reflection on the environmental impact of the research undertaken. Finally, we propose a framework for addressing the making, testing, using, and disposal of NIMEs in the hope that sustainability may become a central concern to researchers.

  In robot drumming, performing double stroke rolls is a key ability. Human drummers learn to play double strokes by just trying it several times. For performing it, a model needs to be learned to provide anticipatory commands during drumming. Joint stiffness plays a key role in rebounding double stroke task and should be considered in the model. We have introduced an interactive learning method for a drum robot to learn joint stiffness for rebounding double stroke task. The model is simulated for a 2-DoF robotic arm. The algorithm is simulated with 3 different drum kits to show the robustness of the learning approach. The simulation results also show significant compatibility with human performance results. In addition, the refined learning algorithm adjusts the stroke timing which is important for producing proper rhythms.

  Moving to music is a universal human phenomenon, and previous studies have shown that people move to music even when they try to stand still. However, are there individual differences when it comes to how much people spontaneously respond to music with body movement? This article reports on a motion capture study in which 34 participants were asked to stand in a neutral position while listening to short excerpts of rhythmic stimuli and electronic dance music. We explore whether personality and empathy measures, as well as different aspects of music-related behaviour and preferences, can predict the amount of spontaneous movement of the participants. Individual differences were measured using a set of questionnaires: Big Five Inventory, Interpersonal Reactivity Index, and Barcelona Music Reward Questionnaire. Liking ratings for the stimuli were also collected. The regression analyses show that Empathic Concern is a significant predictor of the observed spontaneous movement. We also found a relationship between empathy and the participants¡¯ self-reported tendency to move to music.

  In this article, we discuss the challenges and opportunities provided by teaching programming using web audio technologies and adopting a team-based learning (TBL) approach among a mix of colocated and remote students, mostly novices in programming. The course has been designed for cross-campus teaching and teamwork, in alignment with the two-city master's program in which it has been delivered. We present the results and findings from (1) students' feedback; (2) software complexity metrics; (3) students' blog posts; and (4) teacher's reflections. We found that the nature of web audio as a browser-based environment, coupled with the collaborative nature of the course, was suitable for improving the students' level of confidence about their abilities in programming. This approach promoted the creation of group course projects of a certain level of complexity, based on the students' interests and programming levels. We discuss the challenges of this approach, such as supporting smooth cross-campus interactions and assuring students' preknowledge in web technologies (HTML, CSS, and JavaScript) for an optimal experience. We conclude by envisioning the scalability of this course to other distributed and remote learning scenarios in academic and professional settings. This is in line with the foreseen future scenario of cross-site interaction mediated through code.

  After producing ground-breaking computer-based tools to advance the study of human movement, such as the video-visualization techniques contained in the Musical-Gestures Toolbox, Alexander Refsum Jensenius has con-tinued to find more creative and analytical possibilities to intersect our understandings of music and dance. In the current context of technology-assisted misappropriation of tradi-tional songs and dances, I interviewed the Deputy Director of the RITMO Centre on how we might revert the link between new technol-ogies and intangible cultural heritage for the benefit of legitimate bearers. Furthermore, in this interview, Alexander out-lines the embodied and interdisciplinary ap-proach towards music that has grounded the course of his career but even more interesting-ly, he offers insights about the future of expe-riencing dance through technology and the possibility of dancing robots.

  We investigated how the action¨Csound relationships found in electric guitar performance can be used in the design of new instruments. Thirty-one trained guitarists performed a set of basic sound-producing actions (impulsive, sustained, and iterative) and free improvisations on an electric guitar. We performed a statistical analysis of the muscle activation data (EMG) and audio recordings from the experiment. Then we trained a long short-term memory network with nine different configurations to map EMG signal to sound. We found that the preliminary models were able to predict audio energy features of free improvisations on the guitar, based on the dataset of raw EMG from the basic sound-producing actions. The results provide evidence of similarities between body motion and sound in music performance, compatible with embodied music cognition theories. They also show the potential of using machine learning on recorded performance data in the design of new musical instruments.

  Previous studies have shown that movement-inducing properties of music largely depend on the rhythmic complexity of the stimuli. However, little is known about how simple isochronous beat patterns differ from more complex rhythmic structures in their effect on body movement. In this paper we study spontaneous movement of 98 participants instructed to stand as still as possible for 7 minutes while listening to silence and randomised sound excerpts: isochronous drumbeats and complex drum patterns, each at three different tempi (90, 120, 140 BPM). The participants¡¯ head movement was recorded with an optical motion capture system.We found that on average participants moved more during the sound stimuli than in silence, which confirms the results from our previous studies. Moreover, the stimulus with complex drum patterns elicited more movement when compared to the isochronous drum beats. Across different tempi, the participants moved most at 120 BPM for the average of both types of stimuli. For the isochronous drumbeats, however, their movement was highest at 140 BPM. These results can contribute to our understanding of the interplay between rhythmic complexity, tempo and music-induced movement.

  This paper describes the ongoing process of developing RAW, a collaborative body¨Cmachine instrument that relies on `sculpting' the sonification of raw EMG signals. The instrument is built around two Myo armbands located on the forearms of the performer. These are used to investigate muscle contraction, which is again used as the basis for the sonic interaction design. Using a practice-based approach, the aim is to explore the musical aesthetics of naturally occurring bioelectric signals. We are particularly interested in exploring the differences between processing at audio rate versus control rate, and how the level of detail in the signal¨C¨Cand the complexity of the mappings¨C¨Cinfluence the experience of control in the instrument. This is exemplified through reflections on four concerts in which RAW has been used in different types of collective improvisation.

  In acoustic instruments, sound production relies on the interaction between physical objects. Digital musical instruments, on the other hand, are based on arbitrarily designed action--sound mappings. This paper describes the ongoing exploration of an empirically-based approach for simulating guitar playing technique when designing the mappings of 'air instrument' designs. We present results from an experiment in which 33 electric guitarists performed a set of basic sound-producing actions: impulsive, sustained, and iterative. The dataset consists of bioelectric muscle signals, motion capture, video, and audio recordings. This multimodal dataset was used to train a long short-term memory network (LSTM) with a few hidden layers and relatively short training duration. We show that the network is able to predict audio energy features of free improvisations on the guitar, relying on a dataset of three distinct motion types.

  This paper describes a comparative analysis of tracking quality in two infrared marker-based motion capture systems: one older but high-end (Qualisys, purchased in 2009) and the other newer and mid-range (OptiTrack, purchased in 2019). We recorded performances by a string quartet with both systems simultaneously, using the same frame rate. Our recording set-up included a combination of moving markers (affixed to musicians¡¯ bodies) and stationary markers (affixed to music stands). Higher noise levels were observed in Qualisys recordings of stationary markers than in OptiTrack recordings, as well as a greater spatial range, though OptiTrack recordings had a higher rate of outliers (¡°spikes¡± in the signal). In moving markers, increased quantity of motion was associated with increased betweensystem error rates. Both systems showed minimal withintrial drift but a reduction in recording accuracy and precision over the duration of the experiment. Overall, our results show that the older/high-end system (Qualisys) produced slightly lower-quality recordings than the newer/midrange system (OptiTrack). We discuss how our findings may inform researchers¡¯ interpretations of motion capture data, particularly when capturing the types of motion that are important for performing music.

  Previous studies have shown that music may lead to spontaneous body movement, even when people try to stand still. But are spontaneous movement responses to music similar if the stimuli are presented using headphones or speakers? This article presents results from an exploratory study in which 35 participants listened to rhythmic stimuli while standing in a neutral position. The six different stimuli were 45 s each and ranged from a simple pulse to excerpts from electronic dance music (EDM). Each participant listened to all the stimuli using both headphones and speakers. An optical motion capture system was used to calculate their quantity of motion, and a set of questionnaires collected data about music preferences, listening habits, and the experimental sessions. The results show that the participants on average moved more when listening through headphones. The headphones condition was also reported as being more tiresome by the participants. Correlations between participants¡¯ demographics, listening habits, and self-reported body motion were observed in both listening conditions. We conclude that the playback method impacts the level of body motion observed when people are listening to music. This should be taken into account when designing embodied music cognition studies.

  Higher education is facing disruptive changes in many fields. Students wants to have the option of learning anywhere, anytime and in any format. Universities need to develop and deliver to future students a complete learning ecosystem. At the same time universities are facing challenges such as growing costs and the pressure to give the students the knowledge, competence, skills and ability to continuously adapt to future job environments. As a consequence, many universities are investigating new ways of collaboration and sharing resources to cater to the demands of students, industry and society. An example of this collaboration is a new joint master between the two largest Universities in Norway: University of Oslo (UiO) and Norwegian University of Science and Technology (NTNU). In this paper, we present the lessons learned from almost two years of teaching and learning in the new joint master's programme, "Music, Communication and Technology" (MCT), between NTNU and UiO. This programme is a run in a two-campus learning space built as a two-way, audio-visual, high-quality, low-latency communication channel between the two campuses, called "The Portal". Moreover, MCT is the subject of research for the SALTO (Student Active Learning in a Two campus Organisation) project, where novel techniques in teaching and learning are explored, such as team-based learning (TBL), flipped classroom, and other forms of student active learning. Educational elements in this master, provides the student with 21 century skills and deliver knowledge within humanities, entrepreneurship and technology. We elaborate on the technical, pedagogical and learning space-related challenges toward delivering teaching and learning in these cross-university settings. The paper concludes with a set of strategies that can be used to improve student active learning in different scenarios.

  In this paper we present results from our ongoing project Student Active Learning in a Two campus Organization(SALTO). This is funded as part of the Norwegian University of Science and Technology¡¯s (NTNU) Teaching Excellence scheme. The initiative consists of a portfolio of development measures, with the purpose of developing innovative approaches to learning, teaching and assessment. The aim of SALTO is to develop pedagogical strategies for the two-campus master¡¯s program Music, Communication and Technology(MCT). This is a joint program between NTNU and the University of Oslo, with the students being split between the cities of Trondheim and Oslo 500 km apart. The program is built around a shared physical-virtual space -the Portal -with a range of high-quality audiovisual technologies. The SALTO project focuses on how the Portal can be used for all activities in the program, with an emphasis on human-computer interaction, resource sharing and collaboration. This is done by students and teachers exploring educational, methodological, and technological solutions together. As such, the SALTO project uses the Portalas a "living lab", which is constantly evolving and being optimized for student-active learning scenarios. In this paper, we present and discuss three cases from the first year of the project: (1) The MCT Opening Ceremony, (2) A "Christmas concert" between to upper secondary schools in Trondheim and Oslo, (3) An intensive workshop-based course with a mix of preparations, lectures and hands-on exercises. The three cases do in various ways present some of the challenges and possibilities of two-campus teaching.

  INTIMAL is a physical-virtual system for relational listening, exploring the role of the body as interface that keeps memory of place in migratory contexts. The system is developed to integrate the body movements of performers (and their voices) with an oral archive. The system has been informed and tested by nine Colombian migrant women in Europe in a telematic performance between the cities of Oslo, Barcelona and London. In the performance a ¡°complex narrative¡± emerged, for both the improvisers and the audiences. In this paper, we describe the conditions of the narrative environment, and the embodied expressions that emerged. We reflect on how this distributed embodied expression¡ªthrough technological mediated sound and movement interactions¡ªmight further aid processes of collective remembering and catharsis, in a context of conflict and gendered migration.

  QuaverSeries consists of a domain-specific language and a single-page web application for collaborative live coding in music performances. Its domain-specific language borrows principles from both programming and digital interface design in its syntax rules, and hence adopts the paradigm of functional programming. The collaborative environment features the concept of 'virtual rooms', in which performers can collaborate from different locations, and the audience can watch the collaboration at the same time. Not only is the code synchronised among all the performers and online audience connected to the server, but the code executing command is also broadcast. This communication strategy, achieved by the integration of the language design and the environment design, provides a new form of interaction for web-based live coding performances.

  In this paper, we present a course of audio programming using web audio technologies addressed to an interdisciplinary group of master students who are mostly beginners in programming. This course is held in two connected university campuses through a portal space and the students are expected to work in cross-campus teams. The workshop promotes both individual and group work and is based on ideas from science, technology, engineering, arts and mathematics (STEAM), team-based learning and project-based learning. We show the outcomes of this course, discuss the students¡¯ feedback and reflect on the results. We found that it is important to provide individual vs. group work, to use the same code editor for consistent follow-up and to be able to share the screen to solve individual questions. Other aspects inherent to the master (intensity of the courses, coding in a research-oriented program) and to prior knowledge (web technologies) should be reconsidered. We conclude with a wider reflection on the challenges and potentials of using web audio as a programming environment for beginners in STEAM and distance-learning courses.

  We present an approach to analyzing the motion capture data of rowers using bivariate functional principal component analysis (bfPCA). The method has been applied on data from six elite rowers rowing on an ergometer. The analyses of the upper and lower body coordination during the rowing cycle revealed significant differ- ences between the rowers, even though the data was normalized to account for differences in body dimensions. We make an argument for the use of bfPCA and other functional data analysis methods for the quantitative evaluation and description of technique in sports.

  The links between music and human movement have been shown to provide insight into crucial aspects of human¡¯s perception, cognition, and sensorimotor systems. In this study, we examined the influence of music on movement during standstill, aiming at further characterizing the correspondences between movement, music, and perception, by analyzing head sway fractality. Eighty seven participants were asked to stand as still as possible for 500?seconds while being presented with alternating silence and audio stimuli. The audio stimuli were all rhythmic in nature, ranging from a metronome track to complex electronic dance music. The head position of each participant was captured with an optical motion capture system. Long-range correlations of head movement were estimated by detrended fluctuation analysis (DFA). Results agree with previous work on the movement-inducing effect of music, showing significantly greater head sway and lower head sway fractality during the music stimuli. In addition, patterns across stimuli suggest a two-way adaptation process to the effects of music, with musical stimuli influencing head sway while at the same time fractality modulated movement responses. Results indicate that fluctuations in head movement in both conditions exhibit long-range correlations, suggesting that the effects of music on head movement depended not only on the value of the most recent measured intervals, but also on the values of those intervals at distant times.

  This paper describes the process of developing a shared instrument for music¨Cdance performance, with a particular focus on exploring the boundaries between standstill vs motion, and silence vs sound. The piece Vrengt grew from the idea of enabling a true partnership between a musician and a dancer, developing an instrument that would allow for active co-performance. Using a participatory design approach, we worked with sonification as a tool for systematically exploring the dancer¡¯s bodily expressions. The exploration used a ¡°spatiotemporal matrix,¡± with a particular focus on sonic microinteraction. In the final performance, two Myo armbands were used for capturing muscle activity of the arm and leg of the dancer, together with a wireless headset microphone capturing the sound of breathing. In the paper we reflect on multi-user instrument paradigms, discuss our approach to creating a shared instrument using sonification as a tool for the sound design, and reflect on the performers¡¯ subjective evaluation of the instrument.

  The present study investigates how people move and relate to each other ¨C and to the dance music ¨C in a club-like setting created within a motion capture laboratory. Three groups of participants (29 in total) each danced to a 10-minute-long DJ mix consisting of four tracks of electronic dance music (EDM). Two of the EDM tracks had little structural development, while the two others included a typical ¡°break routine¡± in the middle of the track, consisting of three distinct passages: (a) ¡°breakdown¡±, (b) ¡°build-up¡± and (c) ¡°drop¡±. The motion capture data show similar bodily responses for all three groups in the break routines: a sudden decrease and increase in the general quantity of motion. More specifically, the participants demonstrated an improved level of interpersonal synchronization after the drop, particularly in their vertical movements. Furthermore, the participants¡¯ activity increased and became more pronounced after the drop. This may suggest that the temporal removal and reintroduction of a clear rhythmic framework, as well as the use of intensifying sound features, have a profound effect on a group¡¯s beat synchronization. Our results further suggest that the musical passages of EDM efficiently lead to the entrainment of a whole group, and that a break routine effectively ¡°re-energizes¡± the dancing.

  This exploratory study investigates muscular activity characteristics of a group of audience members during an experimental music performance. The study was designed to be as ecologically valid as possible, collecting data in a concert venue and making use of low- invasive measurement techniques. Muscle activity (EMG) from the forearms of 8 participants revealed that sitting in a group could be an indication of a level of group engagement, while comparatively greater muscular activity from a participant sitting at close distance to the stage suggests performance-induced bodily responses. The self-reported measures rendered little evidence supporting the links between muscular activity and live music exposure, although a larger sample size and a wider range of music styles need to be included in future studies to provide conclusive results.

  Background Automated detection of pitch in polyphonic music remains a difficult challenge (Benetos et al., 2013). Robust solutions can be found for simple cases such as monodies. Implementation of perceptive/cognitive models have been so far less successful than engineering methods, and in particular machine learning models. One reference model (Klapuri, 2006) preselects pitch candidates based on harmonic summation and searches for multiple pitches through cancellation. Aims The aim was to conceive a model for pitch detection in polyphonic music able to transcribe in details traditional Norwegian music played on Hardanger fiddle, where more than two strings are played at the same time. The new model should be applicable to other types of music as well. Perceptive and cognitive models should guide the improvement of the state of the art. Main Contribution The model is neither based on a machine-learning training on a given set of samples, nor explicitly relying on stylistic rules. Instead, the methodology consists in conceiving a set of rules as simple and general as possible while offering satisfying results for the chosen corpus of music. We follow some general principles of the model by (Klapuri 2006) while introducing new heuristics. We present a new method for harmonic summation that penalises harmonic series that are sparse, in particular when odd partials are absent, as it would indicate that the actual harmonic series is a multiple of the given pitch candidate. Besides, a multiple of a fundamental can be selected as pitch in addition to the fundamental itself if its attack phase is sufficiently distinctive. For that purpose, we introduce a concept of pitch percept that persists over the whole extent of the note, and that serves as a reference for the detection of higher pitches at harmonic intervals. Results The proposed method enables to obtain transcriptions of relatively good quality, with a low ratio of false positives and false negatives. The construction of the model is under refinement. We are applying this method to the analysis of recordings of Norwegian folk music, containing a large part of Hardinger fiddle pieces and a cappella singing. Implications Automated transcription is of high interest for musicology and music information retrieval. This enables for instance to build large corpora of scores for music analysis and opens news perspectives for computational musicology. By attempting to design computer models based on general rules as simple as possible rather than on machine learning, while resulting in a behaviour in terms of pitch detection that comes closer to human capabilities, we hypothesise that the underlying mechanisms thus modelled might suggest general computational capabilities that could be found in cognitive models as well. In the same time, an improvement of the model based on expertise in music perception and cognition is desired. References Benetos et al. (2013).

  Melodic contour, the ¡®shape¡¯ of a melody, is a common way to visualize and remember a musical piece. The purpose of this paper is to explore the building blocks of a future ¡®gesture-based¡¯ melody retrieval system. We present a dataset containing 16 melodic phrases from four musical styles and with a large range of contour variability. This is accompanied by full-body motion capture data of 26 participants performing sound-tracing to the melodies. The dataset is analyzed using canonical correlation analysis (CCA), and its neural network variant (Deep CCA), to understand how melodic contours and sound tracings relate to each other. The analyses reveal non-linear relationships between sound and motion. The link between pitch and verticality does not appear strong enough for complex melodies. We also find that descending melodic contours have the least correlation with tracing.

  The relationships between human body motion and music have been the focus of several studies characterizing the correspondence between voluntary motion and various sound features. The study of involuntary movement to music, however, is still scarce. Insight into crucial aspects of music cognition, as well as characterization of the vestibular and sensorimotor systems could be largely improved through a description of the underlying links between music and involuntary movement. This study presents an analysis aimed at quantifying involuntary body motion of a small magnitude (micromotion) during standstill, as well as assessing the correspondences between such micromotion and different sound features of the musical stimuli: pulse clarity, amplitude, and spectral centroid. A total of 71 participants were asked to stand as still as possible for 6 min while being presented with alternating silence and music stimuli: Electronic Dance Music (EDM), Classical Indian music, and Norwegian fiddle music (Telespringar). The motion of each participant's head was captured with a marker-based, infrared optical system. Differences in instantaneous position data were computed for each participant and the resulting time series were analyzed through cross-correlation to evaluate the delay between motion and musical features. The mean quantity of motion (QoM) was found to be highest across participants during the EDM condition. This musical genre is based on a clear pulse and rhythmic pattern, and it was also shown that pulse clarity was the metric that had the most significant effect in induced vertical motion across conditions. Correspondences were also found between motion and both brightness and loudness, providing some evidence of anticipation and reaction to the music. Overall, the proposed analysis techniques provide quantitative data and metrics on the correspondences between micromotion and music, with the EDM stimulus producing the clearest music-induced motion patterns. The analysis and results from this study are compatible with embodied music cognition and sensorimotor synchronization theories, and provide further evidence of the movement inducing effects of groove-related music features and human response to sound stimuli. Further work with larger data sets, and a wider range of stimuli, is necessary to produce conclusive findings on the subject.

  Sound and music computing (SMC) is still an emerging field in many institutions, and the challenge is often to gain critical mass for developing study programs and undertake more ambitious research projects. We report on how a long-term collaboration between small and medium-sized SMC groups have led to an ambitious undertaking in the form of the Nordic Sound and Music Computing Network (NordicSMC), funded by the Nordic Research Council and institutions from all of the five Nordic countries (Denmark, Finland, Iceland, Norway, and Sweden). The constellation is unique in that it covers the field of sound and music from the ¡°soft¡± to the ¡°hard,¡± including the arts and humanities, the social and natural sciences, and engineering. This paper describes the goals, activities, and expected results of the network, with the aim of inspiring the creation of other joint efforts within the SMC community.

  This article describes the design and construction of a collection of digitally-controlled augmented acoustic guitars, and the use of these guitars in the installation \textit\{Sverm-Resonans\}. The installation was built around the idea of exploring `inverse¡¯ sonic microinteraction, that is, controlling sounds by the micromotion observed when attempting to stand still. It consisted of six acoustic guitars, each equipped with a Bela embedded computer for sound processing (in Pure Data), an infrared distance sensor to detect the presence of users, and an actuator attached to the guitar body to produce sound. With an attached battery pack, the result was a set of completely autonomous instruments that were easy to hang in a gallery space. The installation encouraged explorations on the boundary between the tactile and the kinesthetic, the body and the mind, and between motion and sound. The use of guitars, albeit with an untraditional `performance¡¯ technique, made the experience both familiar and unfamiliar at the same time. Many users reported heightened sensations of stillness, sound, and vibration, and that the `inverse¡¯ control of the instrument was both challenging and pleasant.

  This chapter presents an overview of some methodological approaches and technologies that can be used in the study of music-related body motion. The aim is not to cover all possible approaches, but rather to highlight some of the ones that are more relevant from a musicological point of view. This includes methods for video-based and sensor-based motion analyses, both qualitative and quantitative. It also includes discussions of the strengths and weaknesses of the different methods, and reflections on how the methods can be used in connection to other data in question, such as physiological or neurological data, symbolic notation, sound recordings and contextual data.

  In this paper, we report on a free-hand motion capture study in which 32 participants ¡®traced¡¯ 16 melodic vocal phrases with their hands in the air in two experimental conditions. Melodic contours are often thought of as correlated with vertical movement (up and down) in time, and this was also our initial expectation. We did find an arch shape for most of the tracings, although this did not correspond directly to the melodic contours. Furthermore, representation of pitch in the vertical dimension was but one of a diverse range of movement strategies used to trace the melodies. Six different mapping strategies were observed, and these strategies have been quantified and statistically tested. The conclusion is that metaphorical representation is much more common than a ¡®graph-like¡¯ rendering for such a melodic sound-tracing task. Other findings include a clear gender difference for some of the tracing strategies and an unexpected representation of melodies in terms of a small object for some of the Hindustani music examples. The data also show a tendency of participants moving within a shared ¡®social box¡¯.

  Background: Previous evidence suggests that the variability of the spatial center of infant movements, calculated by computer-based video analysis software, can identify fidgety general movements (GMs) and predict cerebral palsy. Aim: To evaluate whether computer-based video analysis quantifies specific characteristics of normal fidgety movements as opposed to writhing general movements. Methods: A longitudinal study design was applied. Twenty-seven low-to moderate-risk preterm infants (20 boys, 7 girls; mean gestational age 32 [SD 2.7, range 27¨C36] weeks, mean birth weight 1790 grams [SD 430g, range 1185¨C2700g]) were videotaped at the ages of 3¨C5 weeks (period of writhing GMs) and 10¨C15 weeks (period of fidgety GMs) post term. GMs were classified according to Prechtl¡¯s general movement assessment method (GMA) and by computer-based video analysis. The variability of the centroid of motion (CSD), derived from differences between subsequent video frames, was calculated by means of computer-based video analysis software; group mean differences between GM periods were reported. Results: The mean variability of the centroid of motion (CSD) determined by computer-based video analysis was 7.5% lower during the period of fidgety GMs than during the period of writhing GMs (p = 0.004). Conclusion: Our findings support that the variability of the centroid of motion reflects small and variable movements evenly distributed across the body, and hence shows that computer-based video analysis qualifies for assessment of direction and amplitude of FMs in young infants.

  This paper describes an experiment in which the subjects performed a sound-tracing task to vocal melodies. They could move freely in the air with two hands, and their motion was captured using an infrared, marker-based system. We present a typology of distinct strategies used by the recruited participants to represent their perception of the melodies. These strategies appear as ways to represent time and space through the finite motion possibilities of two hands moving freely in space. We observe these strategies and present their typology through qualitative analysis. Then we numerically verify the consistency of these strategies by conducting tests of significance between labeled and random samples.

  Pitch and spatial height are often associated when describing music. In this paper we present results from a sound tracing study in which we investigate such sound¨Cmotion relationships. The subjects were asked to move as if they were creating the melodies they heard, and their motion was captured with an infra-red, marker-based camera system. The analysis is focused on calculating feature vectors typically used for melodic contour analysis. We use these features to compare melodic contour typologies with motion contour typologies. This is based on using proposed feature sets that were made for melodic contour similarity measurement. We apply these features to both the melodies and the motion contours to establish whether there is a correspondence between the two, and find the features that match the most. We find a relationship between vertical motion and pitch contour when evaluated through features rather than simply comparing contours.

  Background: Absence of fidgety movements (FMs) at 3 months¡¯ corrected age is a strong predictor of cerebral palsy (CP) in high-risk infants. This study evaluates the association between computer-based video analysis and the temporal organization of FMs assessed with the General Movement Assessment (GMA). Methods: Infants were eligible for this prospective cohort study if referred to a high-risk follow-up program in a participating hospital. Video recordings taken at 10¨C15 weeks post term age were used for GMA and computer-based analysis. The variation of the spatial center of motion, derived from differences between subsequent video frames, was used for quantitative analysis. Results: Of 241 recordings from 150 infants, 48 (24.1%) were classified with absence of FMs or sporadic FMs using the GMA. The variation of the spatial center of motion (CSD) during a recording was significantly lower in infants with normal (0.320; 95% confidence interval (CI) 0.309, 0.330) vs. absence of or sporadic (0.380; 95% CI 0.361, 0.398) FMs (P<0.001). A triage model with CSD thresholds chosen for sensitivity of 90% and specificity of 80% gave a 40% referral rate for GMA. Conclusion: Quantitative video analysis during the FMs¡¯ period can be used to triage infants at high risk of CP to early intervention or observational GMA.

  The paper presents results from an experiment in which 91 subjects stood still on the floor for 6 minutes, with the first 3 minutes in silence, followed by 3 minutes with mu- sic. The head motion of the subjects was captured using an infra-red optical system. The results show that the average quantity of motion of standstill is 6.5 mm/s, and that the subjects moved more when listening to music (6.6 mm/s) than when standing still in silence (6.3 mm/s). This result confirms the belief that music induces motion, even when people try to stand still.

  This paper explores sonic microinteraction using muscle sensing through the Myo armband. The first part presents results from a small series of experiments aimed at finding the baseline micromotion and muscle activation data of people being at rest or performing short/small actions. The second part presents the prototype instrument MicroMyo, built around the concept of making sound with little motion. The instrument plays with the convention that inputting more energy into an instrument results in more sound. MicroMyo, on the other hand, is built so that the less you move, the more it sounds. Our user study shows that while such an "inverse instrument" may seem puzzling at first, it also opens a space for interesting musical interactions.

  How do dancers engage with electronic dance music (EDM) when dancing? This paper reports on an empirical study of dancers' pleasurable engagement with three structural properties of EDM: (1) breakdown, (2) build-up, and (3) drop. Sixteen participants danced to a DJ mix in a club-like environment, and the group¡¯s bodily activity was recorded with an infrared, marker-based motion capture system. After they danced, the subjects filled out questionnaires about the pleasure they experienced and their relative desire to move while dancing. Subsequent analyses revealed associations between the group¡¯s quantity of motion and self-reported experiences of pleasure. Associations were also found between certain sonic features and dynamic changes in the dancers' movements. Pronounced changes occurred in the group's quantity of motion during the breakdown, build-up, and drop sections, suggesting a high level of synchronization between the group and the structural properties of the music. The questionnaire confirmed this intersubjective agreement: participants perceived the musical passages consistently and marked the build-up and drop as particularly pleasurable and motivational in terms of dancing. Self-reports demonstrated that the presence and activity of other participants were also important in the shaping of one's own experience, thus supporting the idea of clubbing as an intersubjectively embodied experience.

  As living human beings we are constantly in motion. Even when we try to stand absolutely still, our breathing, pulse and postural adjustments lead to motion at the micro-level. Such micromotion is small, but it is still possible to experience it in the body and it is also visible to others. This chapter reflects on such (un)conscious and (in)voluntary micromotion observed and experienced when one attempts to stand physically still, and how musical sound influences such micromotion.

  The term 'gesture' has represented a buzzword in the NIME community since the beginning of its conference series. But how often is it actually used, what is it used to describe, and how does its usage here differ from its usage in other fields of study? This paper presents a linguistic analysis of the motion-related terminology used in all of the papers published in the NIME conference proceedings to date (2001-2013). The results show that 'gesture' is in fact used in 62 % of all NIME papers, which is a significantly higher percentage than in other music conferences (ICMC and SMC), and much more frequently than it is used in the HCI and biomechanics communities. The results from a collocation analysis support the claim that 'gesture' is used broadly in the NIME community, and indicate that it ranges from the description of concrete human motion and system control to quite metaphorical applications.

  What type of motion capture system is best suited for studying dancing to electronic dance music? The paper discusses positive and negative sides of using camera-based and sensor-based motion tracking systems for group studies of dancers. This is exemplified through experiments with a Qualisys infrared motion capture system being used alongside a set of small inertial trackers from Axivity and regular video recordings. The conclusion is that it is possible to fine-tune an infrared tracking system to work satisfactory for group studies of complex body motion in a ¡°club-like¡± environment. For ecological studies in a real club setting, however, inertial tracking is the most scalable and flexible solution.

  Background: Most studies on Prechtl's method of assessing General Movements (GMA) in young infants originate in Europe. Aim: To determine if motor behavior at an age of 3 months post term is associated with motor development at 12 months post age in VLBW infants in India. Methods: 243 VLBW infants (135 boys, 108 girls; median gestational age 31wks, range 26¨C39wks) were video-recorded at a median age of 11wks post term (range 9¨C16wks). Certified and experienced observers assessed the videos by the ¡°Assessment of Motor Repertoire ¨C 2¨C5 Months¡±. Fidgety movements (FMs) were classified as abnormal if absent, sporadic or exaggerated, and as normal if intermittently or continually present. The motor behaviour was evaluated by repertoire of co-existent other movements (age-adequacy) and concurrent motor repertoire. In addition, videos of 215 infants were analyzed by computer and the variability of the spatial center of motion (CSD) was calculated. The Peabody Developmental Motor Scales was used to assess motor development at 12 months. Results: Abnormal FMs, reduced age adequacy, and an abnormal concurrent motor repertoire were significantly associated with lower Gross Motor and Total Motor Quotient (GMQ, TMQ) scores (p < 0.05). The CSD was higher in children with TMQ scores <90 (-1SD) than in children with higher TMQ scores (p = 0.002). Conclusion: Normal FMs (assessed by Gestalt perception) and a low variability of the spatial center of motion (assessed by computer-based video analysis) predicted higher Peabody scores in 12-month-old infants born in India with a very low birth weight.

  Despite increasingly accessible and user-friendly multi-channel compositional tools, many composers still choose stereo formats for their work, where the compositional process is allied to diffusion performance over a ¡®classical¡¯ loudspeaker orchestra. Although such orchestras remain common within UK institutions as well as in France, they are in decline in the rest of the world. In contrast, permanent, high-density loudspeaker arrays are on the rise, as is the practical application of 3-D audio technologies. Looking to the future, we need to reconcile the performance of historical and new stereo works, side-byside native 3-D compositions. In anticipation of this growing need, we have designed and tested a prototype ¡®Virtualmonium¡¯. The Virtualmonium is an instrument for classical diffusion performance over an acousmonium emulated in higher-order Ambisonics. It allows composers to custom-design loudspeaker orchestra emulations for the performance of their works, rehearse and refine performances off-site, and perform classical repertoire alongside native 3-D formats in the same concert. This paper describes the technical design of the Virtualmonium, assesses the success of the prototype in some preliminary listening tests and concerts, and speculates how the instrument can further composition and performance practice.

  This workshop will explore the potential creation of a community database of digital musical instrument (DMI) designs. In other research communities, reproducible research practices are common, including open-source software, open datasets, established evaluation methods and community standards for research practice. NIME could benefit from similar practices, both to share ideas amongst geographically distant researchers and to maintain instrument designs after their first performances. However, the needs of NIME are different from other communities on account of NIME¡¯s reliance on custom hardware designs and the interdependence of technology and arts practice. This half-day workshop will promote a community discussion of the potential benefits and challenges of a DMI repository and plan concrete steps toward its implementation.

  People tend to perceive many and also salient similarities between musical sound and body motion in musical experience, as can be seen in countless situations of music performance or listening to music, and as has been documented by a number of studies in the past couple of decades. The so-called motor theory of perception has claimed that these similarity relationships are deeply rooted in human cognitive faculties, and that people perceive and make sense of what they hear by mentally simulating the body motion thought to be involved in the making of sound. In this paper, we survey some basic theories of sound-motion similarity in music, and in particular the motor theory perspective. We also present findings regarding sound-motion similarity in musical performance, in dance, in so-called sound-tracing (the spontaneous body motions people produce in tandem with musical sound), and in sonification, all in view of providing a broad basis for understanding sound-motion similarity in music.

  Pulse is a fundamental reference for the production and perception of rhythm. In this paper, we study entrainment to changes in the micro-rhythmic design of the basic pulse of the groove in ¡®Left & Right¡¯ by D¡¯Angelo. In part 1 of the groove the beats have one specific position; in part 2, on the other hand, the different rhythmic layers specify two simultaneous but alternative beat positions that are approximately 50-80 ms apart. We first anticipate listeners¡¯ perceptual response using the theories of entrainment and dynamic attending as points of departure. We then report on a motion capture experiment aimed at engaging listeners¡¯ motion patterns in response to the two parts of the tune. The results show that when multiple onsets are introduced in part 2, the half note becomes a significant additional level of entrainment and the temporal locations of the perceived beats are drawn towards the added onsets.

  A techno-cognitive look at how new technologies are shaping the future of musicking. ¡°Musicking¡± encapsulates both the making of and perception of music, so it includes both active and passive forms of musical engagement. But at its core, it is a relationship between actions and sounds, between human bodies and musical instruments. Viewing musicking through this lens and drawing on music cognition and music technology, Sound Actions proposes a model for understanding differences between traditional acoustic ¡°sound makers¡± and new electro-acoustic ¡°music makers.¡± What is a musical instrument? How do new technologies change how we perform and perceive music? What happens when composers build instruments, performers write code, perceivers become producers, and instruments play themselves? The answers to these pivotal questions entail a meeting point between interactive music technology and embodied music cognition, what author Alexander Refsum Jensenius calls ¡°embodied music technology.¡± Moving between objective description and subjective narrative of his own musical experiences, Jensenius explores why music makes people move, how the human body can be used in musical interaction, and how new technologies allow for active musical experiences. The development of new music technologies, he demonstrates, has fundamentally changed how music is performed and perceived.

  What is a musical instrument? What are the musical instruments of the future? This anthology presents thirty papers selected from the fifteen year long history of the International Conference on New Interfaces for Musical Expression (NIME). NIME is a leading music technology conference, and an important venue for researchers and artists to present and discuss their explorations of musical instruments and technologies. Each of the papers is followed by commentaries written by the original authors and by leading experts. The volume covers important developments in the field, including the earliest reports of instruments like the reacTable, Overtone Violin, Pebblebox, and Plank. There are also numerous papers presenting new development platforms and technologies, as well as critical reflections, theoretical analyses and artistic experiences. The anthology is intended for newcomers who want to get an overview of recent advances in music technology. The historical traces, meta-discussions and reflections will also be of interest for longtime NIME participants. The book thus serves both as a survey of influential past work and as a starting point for new and exciting future developments.

Over the years, we have explored and refined numerous data captures methods, from qualitative observation studies, interviews, and diaries to motion capture and physiological sensing. At the core has always been the attempt to shed light on the complexity of music performance. This includes understanding more about the subtleties of performer's sound-producing actions, sound-facilitating motion, and communicative and expressive gestures. It also includes the intricacies of inter-personal synchronization. Over the years, we have been able to expand from studying duos, trios, and quartets to full orchestras. Today, we have lots of data, some answers, and even more questions than when we started. An excellent starting point for future research.

In Spring 2022, members of EDRL and selected international collaborators of the lab participated in ¡°Rhythm Rising,¡± a workshop week hosted at University of Oslo¡¯s RITMO Centre for Interdisciplinary Studies in Rhythm, Time, and Motion. The workshop featured activities for graduate students to learn the scientific research methodologies of gathering physical, physiological, and neurobiological data from study participants engaged in interactive learning of STEM content. The activities combined the respective expertise of Abrahamson (learning sciences) and Jensenius (embodied music cognition and technology) to investigate sensorimotor micro-processes hypothesized to form the cognitive basis of conceptual understandings, such as hand- and eye actions leading to the emergence of mathematical insight. Whereas the Oslo workshop spurred great enthusiasm among the graduate students, its duration only allowed time for initial data collection. Therefore, we would like to regather in Spring 2024 to continue our collaborative work and to share insights about data analysis, visualization, and interpretation. Concurrently, we¡¯ll develop ideas for future joint research projects.

• Laczko, Balint & Jensenius, Alexander Refsum (2024). Poster for "Synth Maps: Mapping The Non-Proportional Relationships Between Synthesizer Parameters and Synthesized Sound". Show summary

  Parameter Mapping (PM) is probably the most used design approach in sonification. However, the relationship between a synthesizer¡¯s input parameters and the perceptual distribution of its output sounds might not be proportional, limiting its ability to convey relationships within the source data in the sound. This study evaluates a basic Frequency Modulation (FM) synthesis module with perceptually motivated descriptors, measures of spectral energy distribution, and latent embeddings of pre-trained audio representation models. We demonstrate how these metrics do not indicate straightforward relationships between synthesis parameters and perceived sound. This is done using interactive audiovisual scatter plots¡ªSynth Maps¡ªthat can be used to explore the sound distribution of the synthesizer and qualitatively evaluate how well the different representations align with human perception. Link to the code and the interactive Synth Maps are available.

  Equipping future graduates, researchers, and society at large with the skills needed to support the digital transition is becoming a priority on European, national, and institutional agendas. Research data management (RDM) and FAIR data are part of this skillset, and research data careers are increasingly in demand in both the public and private sectors. At organisational level, the availability of staff with data competencies is crucial to support the implementation of FAIR RDM practices and, ultimately, to foster the transition towards Open Science. Data collected by the European University Association show for example how universities are creating dedicated research data support services and hiring specific support staff, but significant disparities exist between countries and institutions. RDM responsibilities still fall to existing members of staff. In many cases, technical skills are only partially available and new dedicated staff is required. Universities who have hired specific research data support roles may still have problems meeting the growing demand for research data expertise. Within this context, a major challenge is represented by the absence of a shared recognition and definition of research management professional profiles, despite recent progress being made at European level through ERA Action 17 on research management. This session will address needs, challenges and opportunities related to the emergence of new research data careers, including the identification of key skills, clear career paths and their integration into research assessment systems. It will do so by showcasing best practices and reflecting on ways forward with a panel of experts representing different actors, i.e. university leaders, research data practitioners and policymakers.

  Throughout 2023, I will stand still for ten minutes around noon every day, in a different room each day. The aim is to collect data about my micromotion and compare it to the qualities of the environment. This project follows a decade-long exploration of human micromotion from both artistic and scientific perspectives. In the talk, I will present results from the annual Norwegian Championships of Standstill, where we have studied the influence of music on people's micromotion.

• Jensenius, Alexander Refsum (2023). Exploring Human Micromotion Through Standing Still. Show summary

  Moving slowly likely puts us into a special state of mind. Subjective reports from various practices including dance, Tai Chi and walking meditation suggest that slow movements can bring participants into a special state involving increased relaxation and awareness. Interestingly, relatively little research has been performed specifically to understand the underlying mechanisms and the possible applications of human slow movement. One reason might be that slow movements are not common in day-to-day life: when we want to move ¨C for example to pick up our cup of coffee - we usually want to do it now. Some evidence suggests that humans tend to avoid moving slowly in different tasks, for example, when improvising movements together. The goal of this meeting is to bring together scholars and practitioners interested in slow movement, and to foster interdisciplinary research on this somewhat neglected topic.

  As a pr¨¦lude for Norway's Constitution Day, this special event celebrated the Norwegian folk music tradition, showcasing our new online archive and demonstrating the richness of Hardanger fiddle music, with live performance. One aim of the project is to conceive new technologies allowing to better access, understand and appreciate Norwegian folk music. In this event, we introduced a new online version of the Norwegian Folk Music Archive and discuss underlying theoretical and technical challenges. A live concert/workshop, with the participation of Olav Lukseng?rd Mjelva, offered a lively introduction to Hardanger fiddle music and its elaborate rhythm. The interests and challenges of automated transcription and analysis were discussed, with the public release of our new software Annotemus. The symposium was organised in the context of the MIRAGE project (RITMO, in collaboration with the National Library of Norway's Digital Humanities Laboratory).

• Riaz, Maham; Upham, Finn; Burnim, Kayla; Bishop, Laura & Jensenius, Alexander Refsum (2023). Comparing inertial motion sensors for capturing human micromotion. Show summary

  The paper presents a study of the noise level of accelerometer data from a mobile phone compared to three commercially available IMU-based devices (AX3, Equivital, and Movesense) and a marker-based infrared motion capture system (Qualisys). The sensors are compared in static positions and for measuring human micromotion, with larger motion sequences as reference. The measurements show that all but one of the IMU-based devices capture motion with an accuracy and precision that is far below human micromotion. However, their data and representations differ, so care should be taken when comparing data between devices.

  In this paper, we reflect on the focus of ¡°newness¡± in NIME research and practice and argue that there is a missing O (for ¡°Old¡±) in framing our academic discourse. A systematic review of the last year¡¯s conference proceedings reveals that most papers do, indeed, present new instruments, interfaces, or pieces of technology. Comparably few papers focus on the prolongation of existing NIMEs. Our meta-analysis identifies four main categories from these papers: (1) reuse, (2) update, (3) complement, and (4) long-term engagement. We discuss how focusing more on these four types of NIME development and engagement can be seen as an approach to increase sustainability.

  ZRob is a robotic system designed for playing a snare drum. The robot is constructed with a passive flexible spring-based joint inspired by the human hand. This paper describes a study exploring rhythmic patterns by exploiting the chaotic dynamics of two ZRobs. In the experiment, we explored the control configurations of each arm by trying to create un- predictable patterns. Over 200 samples have been recorded and analyzed. We show how the chaotic dynamics of ZRob can be used for creating new drumming patterns.

  What is the use of standing still for 10 minutes? I was asking myself when I saw a post on social media. It was a double picture of a man with a mobile phone around his neck displaying some data, and another picture showed the view he saw at that moment. I learned that he stood there for 10 minutes without any movement, listening to the sound that was already there. There were many pictures like this, and I decided to get in contact. So, today, we are in Oslo. We speak with Alexander Refsum Jensenius, a professor of music technology at the University of Oslo, a book author, a music researcher and researching musician working in the fields of embodied music cognition and new interfaces for musical expression. Alexander shares with us his experiences while performing and testing with artistic methods of embodied listening and how people experience music and sound. This goes from experiments with and without the conductor of a Symphony Orchestra to the sounds of our kitchen appliances. We talk about his motion capture lab, where a person¡¯s exact location and micro-movements can be detected while they hear different kinds of music, and how the researchers can understand what moves them. Alexander shares insights about the Norwegian Championship of Stand Still, where until now, 1000s of people have participated, and the winner is the person with the lowest average velocity on standing the stillest over some time. Alexander explains the interplay of body and mind and reveals some secrets on how to move people, for example, on the dance floor or to calm them down. It all has to do with our bpm, the average heartbeat of about 60 beats a minute.

At the core of the argument is the observation that the introduction of new music technologies has led to an increased separation between action and sound in musical performance. This has happened gradually, with pianos and organs being important early examples of instruments that introduced mechanical components between the performer and resonating objects. Today's network-based instruments represent an extreme case of a spatiotemporal dislocation between action and sound. They challenge our ideas of what an instrument can be, who can perform on them, and how they should be analyzed. In the lecture I will explain how we can use the concepts of action-sound couplings and mappings to structure our thinking about such instruments.

• Jensenius, Alexander Refsum (2022). Exploring music performance and perception through motion capture. Show summary

  This talk will present different approaches to capturing human bodily activity. Motion capture can be performed with sensor-based and camera-based systems, each of which has benefits and limitations. Sensor-based systems are flexible and scalable and can easily be used outside laboratory environments. They are good at tracking relative motion and rotation information but less suitable for tracking position. Camera-based systems come in many flavors and can be used with and without markers. They excel at tracking positions but are prone to reflections and environmental noise. As a consequence, camera-based motion capture systems are better suited for laboratory settings. I will discuss my twenty-year-long experience using different motion capture systems to study music-related body motion. This includes research on musicians, including rehearsal techniques and performance strategies. Such studies push the limits of the technology when it comes to precision and accuracy. It is particularly challenging when using motion capture equipment in real-world concert settings. At the University of Oslo, we have successfully captured the motion of both solo and ensemble performances and are currently trying to scale up to a full orchestra. We are also carrying out motion capture of perceivers, audience members in concerts, dancers, and other people moving to music. Through the Norwegian Championship of Standstill, we have delved into human micromotion, the tiniest actions we can perform and perceive. At this level, motion capture can detect physiological signals, such as breathing and heart rate. Data from such studies are interesting scientifically and have also been used in artistic practice. Finally, I will give examples of how real-time motion capture can be used in various creative applications, including "inverse" sonic interaction.

  In this project, we propose an algorithm to convert musical features and structures extracted from monophonic MIDI files to tactile illusions. Mapping music to vibrotactile stimuli is a challenging process since the perceptible frequency range of the skin is lower than that of the auditory system, which may cause the loss of some musical features. Moreover, current proposed models do not warrant the correspondence between the emotional response to music and the vibrotactile version of it. We propose to use tactile illusions as an additional resource to convey more meaningful vibrotactile stimuli. Tactile illusions enable us to add dynamics to vibrotactile stimuli in the form of movement, changes of direction, and localization. The suggested algorithm converts monophonic MIDI files into arrangements of two tactile illusions: ¡°phantom motion¡± and ¡°funneling¡±. The validation of the rendered material consisted of presenting the audio rendered from MIDI files to participants and then adding the vibrotactile component to it. The arrangement of tactile illusions was also evaluated alone. Results suggest that the arrangement of tactile illusions evokes more positive emotions than negative ones. This arrangement was also perceived as more agreeable and stimulating than the original audio. Although musical features such as rhythm, tempo, and melody were mostly recognized in the arrangement of tactile illusions, it provoked a different emotional response from that of the original audio.

Collecting data in a concert situation is non-trivial, and FAIRifying the data is even more challenging. In this talk, I will discuss some challenges with handling privacy and copyright matters in music research. I will also discuss some benefits of working towards more open music research.

  A working group appointed by Universities Norway (UHR) was mandated to recommend guiding principles for the assessment and evaluation of research(ers) in light of the transition to Open Science. This working group proposed a more flexible and holistic framework for recognition and rewards in academic research assessment. The ambition has been to develop a guide that adopts three core principles for assessment: more transparency, greater breadth, and comprehensive assessments as opposed to the one-sided use of indicators.

  Participatory applause: Interactions of audience members clapping at the end of a classical music concert According to musicological studies of audience culture, applause is the most overt form of participation allowed to the collections of individuals attending classical music concerts (Brandl-Risi, 2011; Small, 1998; Tr?ndle, 2020). The final round of applause can exhibit many interesting dynamics related to their collective enthusiasm for the performance (Lupyan & Rifkin, 2003), the local applause culture, and what is on stage during the clapping. Quantitative empirical study of group clapping behaviours has principally depended on participants clapping on request in laboratory settings or A/V recordings from concerts (Neda, 2000) and presentations (Mann et al., 2013). To study the coordination involved in this collective behaviour, we need accurate measurements of individuals clapping voluntarily in a real concert setting. To describe how the appreciative audience members adjust their clapping to each other and the action on stage during the final round of applause, demonstrating their participation at a concert¡¯s end. * After the Danish String Quartet (DSQ) performed their last piece at the Music Lab Copenhagen Concert, the audience clapped continuously for nearly two minutes. During that time, the musicians stood and bowed, had scientific instruments removed from their bodies, left the stage, returned to bow again, and finally left the stage for good. The clapping action of individual participants in this concert experiment was captured by a mobile phone on their chests, and these recordings show how individuals¡¯ clapping contributed to the collective effect shared with the musicians. Through the final applause interval, 70 devices captured clear clap sequences, representing over half of the audience at this chamber performance. In some ways, their applause followed expected patterns for a concert audience. They began to applaud over a very short time interval (Mann et al., 2013), more than half starting within less than a second of each other. After 20 s of independent clapping at rates from under 120 BMP to over 200 BPM, the participants shifted to clapping together on a shared beat, a practice that is common for Danish audiences. This group maintained synchrony for over a minute while steadily accelerating from around 158 BMP to 176 BMP, an expected consequence of mutual adaptation during group clapping (Thomson et al., 2018). The coordinated action was strongest while the musicians were on the stage but a subset of independent clapping broke out while the audience waited for the performers to return for their final round of bows. Participants¡¯ claps were evaluated from two perspectives: the alignment of claps, reflecting the dominant shift from independence to coordination, and the distribution of participants¡¯ clapping rates over time. Despite some measurement challenges, the shift from independent to coordinate clapping emerges strongly from participants¡¯ movements, with the median rate of clapping slowing until a dominant beat takes hold. Individuals¡¯ clap sequences confirm that the independent clapping at the start of the applause is a result of individual participants clapping isochronously at their own rate, separate in rate and phase from their neighbours in the hall. When the audience claps together, they are voluntarily adjusting to the dominant rate and phase of the people in the hall, with little change in the quality of their isochronous clapping action. Drift in the synchronised clapping rate reflects mutual attentiveness while variation in the number of participants contributing to the coordinated claps suggests differences in applause strategy. Many participants opted to coordinate with their peers while some seemed to prioritise reacting to the musicians.

• Kwak, Dongho; Krzyzaniak, Michael Joseph; Danielsen, Anne & Jensenius, Alexander Refsum (2022). A mini acoustic chamber for small-scale sound experiments. Show summary

  This paper describes the design and construction of a mini acoustic chamber using low-cost materials. The primary purpose is to provide an acoustically treated environment for small-scale sound measurements and experiments using ¡Ü 10-inch speakers. Testing with different types of speakers showed frequency responses of <?10?dB peak-to-peak (except the ¡±boxiness¡± range below 900?Hz), and the acoustic insulation (soundproofing) of the chamber is highly efficient (approximately 20?dB?SPL in reduction). Therefore, it provides a significant advantage in conducting experiments requiring a small room with consistent frequency response and preventing unwanted noise and hearing damage. Additionally, using a cost-effective and compact acoustic chamber gives flexibility when characterizing a small-scale setup and sound stimuli used in experiments.

• Lesteberg, Mari & Jensenius, Alexander Refsum (2022). MICRO and MACRO - Developing New Accessible Musicking Technologies. Show summary

  This paper describes the development of two musical instrument prototypes developed to explore how non-haptic music technologies can be accessed from a web browser and how they can offer accessibility for people with low fine motor skills. Two approaches to browser-based motion capture were developed and tested during an iterative design process. This was followed by observational studies of two user groups: one with low fine motor skills and one with normal motor skills. Contrary to our expectations, we found that avoiding the use of buttons and mice did not make the apps more accessible for the participants with low fine motor skills. Furthermore, motion speed was considered more important for people with low motor skills than the size of the control action. The most important finding is that browser-based musical instruments using sensor-based and video-based motion tracking are not only feasible but allow for reaching much larger groups of people than previously possible. This may ultimately lead to both more personalized and accessible musical experiences.

  We present a proof of concept by using the mobile application MusicLab to measure motion during a livestreamed concert and examining its relation to musical features. With the MusicLab App, participants¡¯ own smartphones¡¯ inertial measurement unit (IMU) sensors can be leveraged to record their motion and their subjective experiences collected through survey responses. The MusicLab Lock-down Rave was an Algorave (live-coded dance music) livestreamed concert featuring prolific performers Renick Bell and Khoparzi. They livestreamed for an international audience who wore their smartphones with the MusicLab App while they listened/danced to the performances. From their acceleration, we computed quantity of motion and compared it to musical features that have previously been associated with music-related motion, namely pulse clarity and low and high spectral flux. By encountering challenges and implementing improvements, the MusicLab App has become a useful tool for researching music-related motion.

• Karbasi, Seyed Mojtaba; Jensenius, Alexander Refsum; God?y, Rolf Inge & T?rresen, Jim (2022). A Robotic Drummer with a Flexible Joint: the Effect of Passive Impedance on Drumming. Show summary

  Intelligent robots aimed for performing music and playing musical instruments have been developed in recent years. With the advancements in artificial intelligence and robotic systems, new capabilities have been explored in this field. One major aspect of musical robots that can lead to the emergence of creative results is the ability to learn skills autonomously. To make it feasible, it is important to make the robot utilize its maximum potential and mechanical capabilities to play a musical instrument. Furthermore, the robot needs to find the musical possibilities based on the physical properties of the instrument to provide satisfying results. In this work, we introduce a drum robot with certain mechanical specifications and analyze the capabilities of the robot according to the drumming sound results of the robot. The robot has two degrees of freedom, actuated by one quasi direct-drive servo motor. The gripper of the robot features a flexible joint with passive springs which adds complexity to the movements of the drumstick. In a basic experiment, we have looked at the drum roll performance by the robot while changing a few control variables such as frequency and amplitude of the motion. Both single-stroke and double-stroke drum rolls can be performed by the robot by changing the control variables. The effect of the flexible gripper on the drumming results of the robot is the main focus of this study. Additionally, we have divided the control space according to the type of drum rolls. The results of this experiment lay the groundwork for developing an intelligent algorithm for the robot to learn musical patterns by interacting with the drum.

  In robot drumming, performing double stroke rolls is a key ability. Human drummers learn to play double strokes by just trying it several times. For performing it, a model needs to be learned to provide anticipatory commands during drumming. Joint stiffness plays a key role in rebounding double stroke task and should be considered in the model. We have introduced an interactive learning method for a drum robot to learn joint stiffness for rebounding double stroke task. The model is simulated for a 2-DoF robotic arm. The algorithm is simulated with 3 different drum kits to show the robustness of the learning approach. The simulation results also show significant compatibility with human performance results. In addition, the refined learning algorithm adjusts the stroke timing which is important for producing proper rhythms.

  The potential of Citizen Science is high on the agenda in the discussion on the future of academic research. The European Commission¡¯s Communication ¡°A new ERA for Research and Innovation¡±, published in September 2020, states that ¡°[...] the engagement of citizens, local communities and civil society will [help] achieve greater social impact and increased trust in science.¡± Citizens can contribute in diverse ways, ranging from data collection over data analysis to co-designing projects, and thereby bring academic research and its outcomes closer to society. However, Citizen Science also accentuates ethical and legal questions about ownership of the research process and outcomes, and poses challenges in terms of safeguarding research quality. Addressing these challenges and using the opportunities of Citizen Science will require universities to take the lead and consider the place of Citizen Science within their institutional strategies, as well as the support they offer to research staff. Engaging in inclusive and transparent science, Citizen Science and Open Science are becoming increasingly intertwined. Currently, Citizen Science is described by the European Commission as ¡°both an aim and enabler of Open Science¡±. This joint workshop will discuss themes around institutional support for Citizen Science and offers an opportunity to transfer and share knowledge. The aim is to exchange experiences, lessons learnt, and explore common challenges. To support Citizen Science, the online workshop will discuss tools, guidelines and good practices from Open Science experiences as well. Participating universities will have the opportunity to share expertise, coordinate efforts and exchange advice on services, tools and legal and ethical issues.

  Previous studies have shown that movement-inducing properties of music largely depend on the rhythmic complexity of the stimuli. However, little is known about how simple isochronous beat patterns differ from more complex rhythmic structures in their effect on body movement. In this paper we study spontaneous movement of 98 participants instructed to stand as still as possible for 7 minutes while listening to silence and randomised sound excerpts: isochronous drumbeats and complex drum patterns, each at three different tempi (90, 120, 140 BPM). The participants¡¯ head movement was recorded with an optical motion capture system.We found that on average participants moved more during the sound stimuli than in silence, which confirms the results from our previous studies. Moreover, the stimulus with complex drum patterns elicited more movement when compared to the isochronous drum beats. Across different tempi, the participants moved most at 120 BPM for the average of both types of stimuli. For the isochronous drumbeats, however, their movement was highest at 140 BPM. These results can contribute to our understanding of the interplay between rhythmic complexity, tempo and music-induced movement.

• Bishop, Laura & Jensenius, Alexander Refsum (2020). Reliability of two infrared motion capture systems in a music performance setting. Show summary

  This paper describes a comparative analysis of tracking quality in two infrared marker-based motion capture systems: one older but high-end (Qualisys, purchased in 2009) and the other newer and mid-range (OptiTrack, purchased in 2019). We recorded performances by a string quartet with both systems simultaneously, using the same frame rate. Our recording set-up included a combination of moving markers (affixed to musicians¡¯ bodies) and stationary markers (affixed to music stands). Higher noise levels were observed in Qualisys recordings of stationary markers than in OptiTrack recordings, as well as a greater spatial range, though OptiTrack recordings had a higher rate of outliers (¡°spikes¡± in the signal). In moving markers, increased quantity of motion was associated with increased between-system error rates. Both systems showed minimal within-trial drift but a reduction in recording accuracy and precision over the duration of the experiment. Overall, our results show that the older/high-end system (Qualisys) produced slightly lower-quality recordings than the newer/mid-range system (OptiTrack). We discuss how our findings may inform researchers¡¯ interpretations of motion capture data, particularly when capturing the types of motion that are important for performing music.

  Higher education is facing disruptive changes in many fields. Students wants to have the option of learning anywhere, anytime and in any format. Universities need to develop and deliver to future students a complete learning ecosystem. At the same time universities are facing challenges such as growing costs and the pressure to give the students the knowledge, competence, skills and ability to continuously adapt to future job environments. As a consequence, many universities are investigating new ways of collaboration and sharing resources to cater to the demands of students, industry and society. An example of this collaboration is a new joint master between the two largest Universities in Norway: University of Oslo (UiO) and Norwegian University of Science and Technology (NTNU). In this paper, we present the lessons learned from almost two years of teaching and learning in the new joint master's programme, "Music, Communication and Technology" (MCT), between NTNU and UiO. This programme is a run in a two-campus learning space built as a two-way, audio-visual, high-quality, low-latency communication channel between the two campuses, called "The Portal". Moreover, MCT is the subject of research for the SALTO (Student Active Learning in a Two campus Organisation) project, where novel techniques in teaching and learning are explored, such as team-based learning (TBL), flipped classroom, and other forms of student active learning. Educational elements in this master, provides the student with 21st century skills and deliver knowledge within humanities, entrepreneurship and technology. We elaborate on the technical, pedagogical and learning space-related challenges toward delivering teaching and learning in these cross-university settings. The paper concludes with a set of strategies that can be used to improve student active learning in different scenarios.

  In this paper, we present a course of audio programming using web audio technologies addressed to an interdisciplinary group of master students who are mostly beginners in programming. This course is held in two connected university campuses through a portal space and the students are expected to work in cross-campus teams. The workshop promotes both individual and group work and is based on ideas from science, technology, engineering, arts and mathematics (STEAM), team-based learning and project-based learning. We show the outcomes of this course, discuss the students¡¯ feedback and reflect on the results. We found that it is important to provide individual vs. group work, to use the same code editor for consistent follow-up and to be able to share the screen to solve individual questions. Other aspects inherent to the master (intensity of the courses, coding in a research-oriented program) and to prior knowledge (web technologies) should be reconsidered. We conclude with a wider reflection on the challenges and potentials of using web audio as a programming environment for beginners in STEAM and distance-learning courses.

• Jensenius, Alexander Refsum (2019). Experimenting with Open Research Experiments. Show summary

  Is it possible to do experimental music research completely openly? And what can we gain by opening up the research process from beginning to end? In the talk I will present MusicLab, an open research project at the University of Oslo. The aim is to explore new methods for conducting research, research communication, and education. Each MusicLab event is organized around a public music performance, during which we collect data from both musicians and audience members. Here we explore different types of sensing systems that work in real-world contexts, such as breathing, heartbeat, muscle tension, or motion. The events also contain an edutainment element through panel discussions as well as "data jockeying" in the form of live data analysis. The collected data is made publicly available, and forms the basis for further analysis and publications after the event. Opening up the research process is conceptually, practically, and technologically challenging for everyone involved. The benefit is that it has helped us solve a number of issues when it comes to GDPR and copyright. It has also pushed our research in directions that we previously had never thought about, and helped us communicate this to new users.

  INTIMAL is an interactive system for relational listening, which integrates physical-virtual interfaces for people to sonically improvise between distant locations. The aim is to embrace two key aspects in the context of human migration: the sense of place and the sense of presence. This paper reflects on the use of INTIMAL in a long-distance improvisation between the cities of Oslo, Barcelona and London in May 2019. This improvisation was performed by nine Colombian migrant women, who had been involved in a research process using the Deep Listening? practice developed by Pauline Oliveros. Here we describe the performance setting and the implementation of the first two interfaces of the system: MEMENTO, an ¡°embodied¡± navigator of an oral archive of Colombian women¡¯s testimonies of conflict and migration; and RESPIRO, a sonification system that transmits and sonifies live, breathing signals between distant locations. We reflect on how the two interfaces facilitated and challenged the improvisers¡¯ listening experiences and connections.

  This presentation will summarize findings from my research into music-related micromotion. This includes the smallest human motion that we can perform and perceive, typically measured at at a scale of millimeters. We have carried out a series of studies of such micromotion, in which people have been asked to try to stand still on the floor, both in silence and with (musical) sound. By measuring their bodily responses with different types of motion tracking and physiological devices we find a number of similarities between people's quantity and quality of motion. This has been the starting point for exploring the use of micromotion in musical practice, what I call 'sonic microinteraction'. This includes standstill performances with interactive sound and light. It also includes several installations with our ensemble of self-playing guitars. These are hybrid instruments, using digital sound-production through acoustically resonating guitars. They are controlled through inverse microinteraction, meaning that you need to focus on standing still to produce any sound. This challenges our traditional understanding of the affordance of musical instruments, and opens for both artistically and scientifically interesting perspectives.

  What is an instrument in our increasingly electrified world? In this talk I will present a set of theoretical building blocks from my forthcoming book on "musicking in an electronic world". At the core of the argument is the observation that the introduction of new music technologies has led to an increased separation between action and sound in musical performance. This has happened gradually, with pianos and organs being important early examples of instruments that introduced mechanical components between the performer and resonating objects. Today's network-based instruments represent an extreme case of a spatiotemporal dislocation between action and sound. They challenge our ideas of what an instrument can be, who can perform on them, and how they should be analyzed. In the lecture I will explain how we can use the concepts of action-sound couplings and mappings to structure our thinking about such instruments. This will be used at the heart of a new organology that embraces the qualities of both acoustic and electroacoustic instruments.

  Exploring the role of the body as an interface that keeps memory of place, INTIMAL physical-virtual ¡°embodied¡± system, integrates body movement, voice, and an oral archive, as an artistic platform for relational listening (Alarc¨®n, 2019), using networking technologies for telematic sonic improvisatory performances, in the context of geographical migration. INTIMAL has been informed by a case study with nine Colombian migrant women in Europe, listening to their migrations, and to an oral archive with testimonies of conflict and migration by other Colombian migrant women.1 The first two interfaces created for the system: MEMENTO (a spoken word retrieval system), and RESPIRO (for transmission and sonification of breathing data), have been tested by the research participants in a telematic sonic improvisatory public improvisatory performance between the cities of Oslo, Barcelona, and London. In the performance, proposed as a shared dream, a ¡°complex narrative¡± (Grishakova & Poulaki, 2019) emerged, for both the improvisers and the audiences. In this paper, we describe the conditions of the narrative environment, and the embodied expressions that emerged¡ªincluding body movement, voice, spoken word, and breathing¡ªestablishing connections between gendered migration, and Colombian conflict. We reflect on how distributed improvisatory embodied expression, and relational listening through technological mediations, aids the process of collective remembering (Wertsch, 2001), in a complex context of conflict and migration.

  The influence of acoustic stimuli and feedback in sport has been explored as means of optimizing technique, in particular during training. Interactive and adaptive acoustic systems have been evaluated for rowing, with results showing a significant increase in boat velocity. However, assessment of the effects of acoustic feedback and pacing in the technical aspects of rowing is still scarce. Previous studies on the smoothness of the stroke force profile have shown that smoothness metrics can qualitatively reflect movement coordination. In this study, we quantify and compare hand movement smoothness from rowers performing under three acoustic conditions: silence, verbal instructions, and acoustic pacing.

  Norwegian University of Science and Technology (NTNU) Teaching Excellence is an integrated and wide-ranging initiative aimed at helping NTNU to achieve its goal to providing education characterized by quality at a high international level. The initiative consists of a portfolio of development measures, with the purpose to develop innovative approaches to learning, teaching and assessment. SALTO (Student Active Learning in a Two campus Organization) is one of the development projects founded for the period 2018-2020. The project is based on a study where the students are divided into two campuses. The aim is to develop effective pedagogy with activity at both campuses at the same time, with particular emphasis on interaction, resource sharing and communication/collaboration. The project aims to allow students and teachers to explore educational, methodological, and technological solutions together. A new joint master's program in "Music, Communication and Technology" (MCT) between NTNU and University in Oslo (UiO), constitutes the framework for the SALTO project. The common pedagogy, technology and shared learning space between the two Universities, is hereafter defined as the Portal. SALTO will utilize the MCT Portal as an arena/living lab to evolve and optimize student active learning scenarios. In this paper, we elaborate on the issues, challenges and potential with three different scenarios, which emerged during the first 6 months of the project: (1) The Opening Ceremony between NTNU and UiO, with a combo of talks and performance. (2) A live Christmas concert connecting two high schools 500 km apart (Trondheim-Oslo). (3) An intense cross-university course with a combo of preparations, lectures and hands-on exercises.

  This workshop is intended to discuss how we think about and handle research ethics at NIME conferences. A number of NIME papers involved studies on/with humans. Most of these are on volunteering adults, but there are also examples of studies with children, and with patients. We also see an interest in the community to carry out research on/with animals. NIME¡¯s current ethical guidelines do not take these perspectives into account. The Steering Committee therefore sees the need to develop better and more up-to-date ethical guidelines for the conference. This is to create an increased awareness about the needs for ethical considerations in the community, but also as guidelines for reviewers and conference chairs. NIME is proud of being a very heterogeneous community, covering people working in a large number of different scientific disciplines, artistic practices, as well as R&D in the industry. Needless to say, this breadth of perspectives also means that it is difficult to impose the same guidelines on all studies. NIME researchers also have to abide to a number of different regulations at institutional, regional, national, continental and international levels. The workshop will consist of short introductions to some challenges faced when carrying out research on/with humans and animals, in both scientific and artistic contexts. This will be followed by group-based brainstorming and a final plenary discussion.

• Lartillot, Olivier & Jensenius, Alexander Refsum (2018). SoundTracer. Show summary

  Discover traditional Norwegian music by drawing gestures with your iPhone or iPad. First draw a gesture by moving your iPhone or iPad up and down, to indicate ascending and descending melody. A simple sound is played while you move your device, its pitch gets higher when you move up, and gets lower when you move down. You can also indicate the beginning of a new note by moving abruptly the phone up or down (a blue vertical line indicates the note position). It is also possible to indicate a particular note without indication of pitch by performing a quick movement down and up (a red vertical line indicates the note position). Once you have terminated your gesture (by tapping once), the piece of music that contains the melodic gesture closest to your gesture is presented. The title and genre of that piece of music is indicated, as well as the performer and the district in Norway where it comes from. A melodic curve of the specific melodic gesture from the song is displayed below your own gesture. The matching between your gesture and the melody is based on a temporal alignment of their contours: the ascending parts of your gesture is aligned with the ascending parts of the melody, and same for the descending parts. The temporal note locations you have specified (bleu and red vertical lines) are also tentatively aligned with corresponding note changes in the melody. Some parts may be skipped, and are shown in red in the curves. When the music is played, a cursor moves throughout both curves so that you can follow the music while looking at the gestures. SoundTracer uses Apple's ARKit technology, solely in order to precisely track the location of your iPhone or iPad. For that reason, there is no actual Augmented Reality, and the camera is solely used to improve the precision of the tracking, without displaying the actual frames of the camera. For the moment, the catalogue of music is composed of around 50 pieces, and only the initial part of the melody is considered. The catalogue includes a few tunes played on the traditional Norwegian Hardanger fiddle, and songs sung a cappella. SoundTracer will be progressively improved with more music. SoundTracer is an innovation project led by Alexander Refsum Jensenius, supported by the University of Oslo and developed in collaboration with the National Library of Norway.

  This exploratory study investigates muscular activity characteristics of a group of audience members during an experimental music performance. The study was designed to be as ecologically valid as possible, collecting data in a concert venue and making use of low-invasive measurement techniques. Muscle activity (EMG) from the forearms of 8 participants revealed that sitting in a group could be an indication of a level of group engagement, while comparatively greater muscular activity from a participant sitting at close distance to the stage suggests performance-induced bodily responses. The self-reported measures rendered little evidence supporting the links between muscular activity and live music exposure, although a larger sample size and a wider range of music styles need to be included in future studies to provide conclusive results.

  Background Automated detection of pitch in polyphonic music remains a difficult challenge (Benetos et al., 2013). Robust solutions can be found for simple cases such as monodies. Implementation of perceptive/cognitive models have been so far less successful than engineering methods, and in particular machine learning models. One reference model (Klapuri, 2006) preselects pitch candidates based on harmonic summation and searches for multiple pitches through cancellation. Aims The aim was to conceive a model for pitch detection in polyphonic music able to transcribe in details traditional Norwegian music played on Hardanger fiddle, where more than two strings are played at the same time. The new model should be applicable to other types of music as well. Perceptive and cognitive models should guide the improvement of the state of the art. Main Contribution The model is neither based on a machine-learning training on a given set of samples, nor explicitly relying on stylistic rules. Instead, the methodology consists in conceiving a set of rules as simple and general as possible while offering satisfying results for the chosen corpus of music. We follow some general principles of the model by (Klapuri 2006) while introducing new heuristics. We present a new method for harmonic summation that penalises harmonic series that are sparse, in particular when odd partials are absent, as it would indicate that the actual harmonic series is a multiple of the given pitch candidate. Besides, a multiple of a fundamental can be selected as pitch in addition to the fundamental itself if its attack phase is sufficiently distinctive. For that purpose, we introduce a concept of pitch percept that persists over the whole extent of the note, and that serves as a reference for the detection of higher pitches at harmonic intervals. Results The proposed method enables to obtain transcriptions of relatively good quality, with a low ratio of false positives and false negatives. The construction of the model is under refinement. We are applying this method to the analysis of recordings of Norwegian folk music, containing a large part of Hardinger fiddle pieces and a cappella singing. Implications Automated transcription is of high interest for musicology and music information retrieval. This enables for instance to build large corpora of scores for music analysis and opens news perspectives for computational musicology. By attempting to design computer models based on general rules as simple as possible rather than on machine learning, while resulting in a behaviour in terms of pitch detection that comes closer to human capabilities, we hypothesise that the underlying mechanisms thus modelled might suggest general computational capabilities that could be found in cognitive models as well. In the same time, an improvement of the model based on expertise in music perception and cognition is desired. References Benetos et al. (2013).

  Introduction Postural stability have been the focus of a number of studies on fall prevention and sports, with an emphasis on walking dynamics1 . Fewer studies have aimed at understanding the influence of sound stimuli in standing posture sway 2. Although the vestibular system plays a fundamental role in the control of postural stability, it has also been shown to be key in embodied cognition processes 3. It is in part through the vestibular system that music activates motor areas in the brain to induce movement, while body movement enhances the cognitive processing of sound and music 3. This study explored the influence of music on postural control by measuring synchronization between body center of mass (COM) sway with music. Methods 7 women (32 ¡À 4.39 years, 1.73 ¡À 0.04 m, mean ¡À SD), and 5 men (29.67 ¡À 4.63 years, 1.81 ¡À 0.04 m) participated in the study. Participants were asked to stand still for 6 minutes as they were presented with alternating segments of silence and music. COM movements were measured from the position of a passive marker placed in the midline of the sacrum, recorded using an infrared motion capture system. Radial and vertical COM movements were cross-correlated with the pulse clarity, RMS, and spectral centroid of the stimuli. Results Paired samples t-test revealed differences in COM radial and vertical sway between silent and music conditions to be significant at the 0.05 level. A repeated measures ANOVA showed a significant effect of the stimuli on COM sway (p < 0.05). The effect of the stimuli on the lag of maximum cross-correlation (delay) between COM radial sway and RMS was shown to be significant (p < 0.05). Differences in delay between pulse clarity and COM vertical sway were significant between stimuli (p < 0.05 ). Discussion Results suggest that the effect of RMS in music-induced postural sway might be predominant in the radial plane, with anticipatory behavior observed for stimuli with low RMS. Vertical sway correspondence patterns suggest anticipatory vertical motion to music spectral centroid. A more robust understanding of a range of music features and their links with induced movement could lead to insight into the role of the vestibular and sensory systems in balance control.

  Sound and music computing (SMC) is still an emerging field in many institutions, and the challenge is often to gain critical mass for developing study programs and undertake more ambitious research projects. We report on how a long-term collaboration between small and medium-sized SMC groups have led to an ambitious undertaking in the form of the Nordic Sound and Music Computing Network (NordicSMC), funded by the Nordic Research Council and institutions from all of the five Nordic countries (Denmark, Finland, Iceland, Norway, and Sweden). The constellation is unique in that it covers the field of sound and music from the ¡°soft¡± to the ¡°hard,¡± including the arts and humanities, the social and natural sciences, and engineering. This paper describes the goals, activities, and expected results of the network, with the aim of inspiring the creation of other joint efforts within the SMC community.

  Stillness Under Tension? is an ensemble standstill work for Myo gesture control armband and Bela embedded music platform. Humans are incapable of standing completely still due to breathing and other involuntary micromotions. This work explores the expressive space of standing still through an inverse action-sound mapping: less movement leads to more sound. Four performers stand as still as possible on stage, each wearing a Myo armband connected to a Bela embedded sound processing platform. The Myo is used to measure the performers movement, and the muscle activity in their forearm which they can use--both voluntarily and involuntarily--to control a synthesised sound world. Each performer uses one Myo and Bela in a musical space defined by their physical position and posture while standing still.

  This article describes the design and construction of a collection of digitally-controlled augmented acoustic guitars, and the use of these guitars in the installation \textit\{Sverm-Resonans\}. The installation was built around the idea of exploring `inverse¡¯ sonic microinteraction, that is, controlling sounds by the micromotion observed when attempting to stand still. It consisted of six acoustic guitars, each equipped with a Bela embedded computer for sound processing (in Pure Data), an infrared distance sensor to detect the presence of users, and an actuator attached to the guitar body to produce sound. With an attached battery pack, the result was a set of completely autonomous instruments that were easy to hang in a gallery space. The installation encouraged explorations on the boundary between the tactile and the kinesthetic, the body and the mind, and between motion and sound. The use of guitars, albeit with an untraditional `performance¡¯ technique, made the experience both familiar and unfamiliar at the same time. Many users reported heightened sensations of stillness, sound, and vibration, and that the `inverse¡¯ control of the instrument was both challenging and pleasant.

• Zelechowska, Agata; Gonzalez Sanchez, Victor Evaristo & Jensenius, Alexander Refsum (2018). How music moves us? Studying human body micromotion in music perception. Show summary

  Music has the power to influence not only our thoughts and emotions, but also various physiological processes in our bodies. Furthermore, it often encourages physical movement of the listener. While there are numerous studies describing spontaneous psychophysiological responses to music that are linked with emotions, spontaneous body movement to music has became a topic of exploration relatively recently. Mostly, it has been studied in the context of free dance (Burger et al., 2013) or synchronization to musical rhythm while performing repetitive movements such as walking (Styns et al., 2007). But what can we observe if the participants are just standing still? In our project ¡°MICRO - Human Bodily Micromotion in Music Perception and Interaction¡± we focus on movements so small that they can be unnoticed both by observer and performer, and that can happen involuntarily. This is what we call ¡°micromotion¡± of the human body. To see how these small movements are affected by music, we develop different experiments using mainly motion capture technology, but also physiological measures such as electromyography (EMG). In this presentation I would like to describe some of our research methods, findings and plans. In one of the experiment paradigms, disguised as the ¡°Norwegian Championship of Standitill¡±, we invite groups of participants to the laboratory and ask them to stand as still as possible while we present them with segments of selected music or silence. The head motion of each participant is captured using an infrared optical system. In 2012, 91 subjects stood on the floor for 3 minutes in silence and 3 minutes listening to music of increasing level of rhythmicality and energy (Jensenius et al., 2017). In 2017, 71 participants listened to 6 minutes consisting of segments of silence alternating with electronic dance music (EDM), classical Indian music or Norwegian fiddle music. In both studies we observed higher mean quantity of motion of the participants (QoM) in music condition compared to silence condition, and the effect was driven mostly by EDM. We also observed correlations between QoM and participant¡¯s age, height and standing strategy (locked knees), although these results are mixed between the two studies. The future goal is to look more closely into specific features in music that correspond with observed movement, to search for signs of rhythmic entrainment, and to see what demographic and psychological factors might contribute to interpersonal differences in music induced body micromotion.

  This paper describes an experiment in which the subjects performed a sound-tracing task to vocal melodies. They could move freely in the air with two hands, and their motion was captured using an infrared, marker-based system. We present a typology of distinct strategies used by the recruited participants to represent their perception of the melodies. These strategies appear as ways to represent time and space through the finite motion possibilities of two hands moving freely in space. We observe these strategies and present their typology through qualitative analysis. Then we numerically verify the consistency of these strategies by conducting tests of significance between labeled and random samples.

The analysis is focused on calculating feature vectors typically used for melodic contour analysis. We use these features to compare melodic contour typologies with motion contour typologies. This is based on using proposed feature sets that were made for melodic contour similarity measurement. We apply these features to both the melodies and the motion contours to establish whether there is a correspondence between the two, and find the features that match the most. We find a relationship between vertical motion and pitch contour when evaluated through features rather than simply comparing contours.

• Jensenius, Alexander Refsum (2017). Micro, Meso, Macro: Music-related body motion at different spatiotemporal levels. Show summary

  Performance of acoustic instruments is often happening at a spatiotemporal micro-level. Violin performance, for example, is based on an extreme control of the spatial placement of the left-hand fingering and the right-hand bow strokes. Even though there are exceptions, many digital musical instruments (DMIs) are based on meso- or macro-level control, that is, fairly large and slow control actions compared to acoustic instruments. In this talk I will present a theoretical framework for sound-producing actions and a related organological model. This will be exemplified with some of my empirical results of music-induced dancing, "air instrument" performance and sonic microinteraction.

  This presentation will focus on my research on human micromotion in musical contexts. My scientific research has focused on understanding more about the phenomenon of human standstill and how music influences our micromotion when standing still. My artistic research has focused on the exploration of micromotion in music and dance performance, and particularly how it is possible to set up systems for sonic microinteraction. My two separate "tracks" of research, the scientific and artistic, have positively reinforced each other, shedding light on a level of musical expressivity on the boundary between the conscious and the unconscious, the voluntary and the involuntary.

  This paper explores sonic microinteraction using muscle sensing through the Myo armband. The first part presents results from a small series of experiments aimed at finding the baseline micromotion and muscle activation data of people being at rest or performing short/small actions. The second part presents the prototype instrument MicroMyo, built around the concept of making sound with little motion. The instrument plays with the convention that inputting more energy into an instrument results in more sound. MicroMyo, on the other hand, is built so that the less you move, the more it sounds. Our user study shows that while such an "inverse instrument" may seem puzzling at first, it also opens a space for interesting musical interactions.

  What type of motion capture system is best suited for studying dancing to electronic dance music? The paper discusses positive and negative sides of using camera-based and sensor-based motion tracking systems for group studies of dancers. This is exemplified through experiments with a Qualisys infrared motion capture system being used alongside a set of small inertial trackers from Axivity and regular video recordings. The conclusion is that it is possible to fine-tune an infrared tracking system to work satisfactory for group studies of complex body motion in a ¡°club-like¡± environment. For ecological studies in a real club setting, however, inertial tracking is the most scalable and flexible solution.

An anthology is necessarily selective, and ours is no exception. As we present in this paper, the aim has been to represent the wide range of artistic, scientific, and technological approaches that characterize the NIME conference. The anthology also includes critical discourse, and through acknowledgment of the strengths and weaknesses of the NIME community, we propose activities that could further diversify and strengthen the field.

• Barrett, Natasha & Jensenius, Alexander Refsum (2016). The ¡®Virtualmonium¡¯: an instrument for classical sound diffusion over a virtual loudspeaker orchestra. Show summary

  Despite increasingly accessible and user-friendly multi-channel compositional tools, many composers still choose stereo formats for their work, where the compositional process is allied to diffusion performance over a ¡®classical¡¯ loudspeaker orchestra. Although such orchestras remain common within UK institutions as well as in France, they are in decline in the rest of the world. In contrast, permanent, high-density loudspeaker arrays are on the rise, as is the practical application of 3-D audio technologies. Looking to the future, we need to reconcile the performance of historical and new stereo works, side-byside native 3-D compositions. In anticipation of this growing need, we have designed and tested a prototype ¡®Virtualmonium¡¯. The Virtualmonium is an instrument for classical diffusion performance over an acousmonium emulated in higher-order Ambisonics. It allows composers to custom-design loudspeaker orchestra emulations for the performance of their works, rehearse and refine performances off-site, and perform classical repertoire alongside native 3-D formats in the same concert. This paper describes the technical design of the Virtualmonium, assesses the success of the prototype in some preliminary listening tests and concerts, and speculates how the instrument can further composition and performance practice.

  This workshop will explore the potential creation of a community database of digital musical instrument (DMI) designs. In other research communities, reproducible research practices are common, including open-source software, open datasets, established evaluation methods and community standards for research practice. NIME could benefit from similar practices, both to share ideas amongst geographically distant researchers and to maintain instrument designs after their first performances. However, the needs of NIME are different from other communities on account of NIME¡¯s reliance on custom hardware designs and the interdependence of technology and arts practice. This half-day workshop will promote a community discussion of the potential benefits and challenges of a DMI repository and plan concrete steps toward its implementation.

• Jensenius, Alexander Refsum (2016). The Influence of Music on Human Standstill. Show summary

  This paper reports on a study of how music influences people standing still, with the aim to investigate: (a) How (much) people move when standing still in silence? (b) How (much) musical sound influences people's standstill? A total of 103 participants (mean age 25 years, equal gender balance) were recruited to the study, which was presented as a "championship" of standstill. The participants each wore a reflective marker on their head, and its position was recorded using a state-of-the-art motion capture system. The task was to stand still on the floor for 6 minutes, 3 minutes in silence and 3 minutes with music. The musical stimuli were 7 excerpts of 20-40 seconds duration, ranging from slow, non-rhythmic music for the first excerpts to dance music at the end. After omitting subjects with with incomplete data sets, 91 participants have been included in the study. The analysis shows that the average quantity of motion (QoM), calculated as the cumulative distance travelled for each of the head markers, was 6.5 mm/s (std: 1.6 mm/s) for the entire data set. For the 3-minute parts without music we found an average QoM of 6.3 mm/s (std 1.4 mm/s), as opposed to 6,6 mm/s (std 2,2 mm/s) for the part with music. The results are even more clear when looking at individual stimuli, with a QoM of 6,8 mm/s (std 2,3 mm/s) for the last dance music example. Contrary to our expectations, no particular spatiotemporal differences were found in the motion patterns for different musical excerpts. The study confirmed the level of micromotion found in human standstill (6.5 mm/s QoM) found in our previous longitudinal studies. The study also confirmed our expectation that people spontaneously move to music, even when specifically trying to stand still. The study did not, however, confirm any spatiotemporal differences for the different musical material. Future studies will include looking systematically at how musical features influence both the quantity and quality of standstill.

• Lyons, Michael J. & Jensenius, Alexander Refsum (2016). An Anthology of Fifteen Years of Musical Interface Research and Practice. Show summary

  To mark the fifteenth year of the New Interfaces for Musical Expression (NIME) conference, we initiated a project to compile an anthology of works representing the development and state of the art of musical interface research since 2001, when the first NIME was held as a two-day workshop of the ACM CHI conference (Poupyrev et al, 2001). To date, more than 1300 research articles have been published at the NIME conference, and similarly many live performances and demonstrations have been presented. In editing our anthology we selected about 30 representative articles from the NIME literature for their perceived impact and coverage of a wide range of interests. Prior works were augmented with commentaries from original authors and third-party experts. Authors and experts were given the opportunity to critique each others commentary before submitting final versions of their texts. The anthology covers the field of musical research broadly, if not exhaustively, including topics such as musical gesture recognition, augmented instruments, expressive performance with: bio-sensors, mobile devices, vision-based and haptic interfaces, various theoretical and social issues relating to musical interface research and other topics. At the time of writing, a version of the anthology, titled ¡°A NIME Reader - Fifteen years of New Interfaces for Musical Expression¡± (Jensenius and Lyons, 2016) has been sent to the publisher and to authors for feedback, we therefore expect to be able to provide a final version of the work to the research community sometime in 2016. We would therefore like to use this opportunity to announce the results of this project to the wider, related research community. The presentation, which will constitute our first public announcement of the musical interface anthology project, will outline our reasons for undertaking the work and report on the process by which we selected the range of topics and articles for the anthology. We will summarize observations and lessons learned from organizing and editing the peer commentaries on the articles, and propose future activities which could benefit musical interface and related research communities.

  Denne presentasjonen vil fokusere p? utviklingen av et pedagogisk musikkteknologikonsept vi har kalt ¡°L?r kidsa musikkoding¡±. Prosjektet springer ut av forskningsaktivitetene i fourMs-gruppen ¨C Music, Mind, Motion, Machines ¨C ved UiO, som jobber i grenselandet mellom opplevelse og skaping av musikk ved hjelp av ulike former for teknologier. M?let med prosjektet er ? utvikle et pedagogisk konsept for design av elektronisk musikk med utgangspunkt i enkel programvare og elektronikk. I tillegg er vi opptatt av ? vise at det er mulig ? benytte musikk som utgangspunkt for ? l?re b?de matematikk, elektronikk og programmering for elever helt ned i grunnskolen. Prosjektet er dermed godt posisjonert i forhold til ? svare p? behovet for faglig fornyelse og konvergens som det ettersp?rres i rapporten Fremtidens skole fra Ludvigen-utvalget. Vi har gjennom flere ?r bygget opp b?de emner (blant annet MUS2830 - Interaktiv musikk) og pedagogiske opplegg (Oslo Laptop Orchestra og Oslo Mobile Orchestra) som har v?rt rettet mot universitetsstudenter. N? tilpasser vi og videreutvikler flere av ideene herfra til bruk i skolesammenheng. Dette krever en annen skalering av b?de opplegg og teknologi, slik at det kan fungere med st?rre grupper (20-30 elever) og innenfor andre tidsrammer (fra enkelttimer til ukeslange workshops). Den f?rste fasen av prosjektet gjennomf?res h?sten 2015 og dreier seg om ? oversette og tilpasse det nettbaserte musikkprogrammeringsspr?ket Gibber til norsk. Gibber gj?r det mulig ? programmere rett i en nettleser, slik at det er minimalt med drifts- og installeringsbehov, og det fungerer p? b?de datamaskiner og ulike mobilplattformer. En viktig del av arbeidet er ? utvikle et sett musikalsk engasjerende eksempler, som ogs? legger opp til en trinnvis ?kning i kompleksitet av matematikk, signalbehandling, og programmering.

  The goal of this thesis was to develop and experiment with a set of sonification tools to explore participant data from standstill competitions. Using data from the 2012 Norwegian Championship of Standstill, three sonification models were developed using the Max/MSP programming environment. The first section of the thesis introduces sonification as a method for data exploration and discusses different sonification strategies. Momentary Displacement of the position was derived from the position data and parameter mapping methods were used to map the data features with sound parameters. The displacement of position in the XY plane or the position changes along the Z-Axis can be mapped either to white-noise or to a sine tone. The data variables control the amplitude and a filter cut-off frequency of the white noise or the amplitude and frequency of the sine tone. Moreover, using sound spatialization together with sonification was explored by mapping position coordinates to spatial parameters of a sine tone. A ¡°falling¡± effect of the standing posture was identified through the sonification. Also audible were the participants¡¯ breathing patterns and postural adjustments. All in all, the implemented sonification methods can be effectively used to get an overview of the standstill dataset.

  Today, there are several toolboxes which can work on audio, motion, or other sensor data. These toolboxes are very useful to provide characteristic analysis of audio and motion. Unfortunately, the analysis is done separately by different toolboxes. This results in inconvenience when we want to work on these data simultaneously. So developing a toolbox which integrates the existing toolboxes is necessary. The main goal of the project is to integrate these toolboxes in Matlab and provide video analysis combined with audio and motion capture data. This would be important for our interdisciplinary research on music and motions through fourMs as well as for external work on e.g. analyzing video recording for early child diagnosis of cerebral palsy. This project presents the development of a toolbox for Matlab entitled ¡°Musical Gestures (MG) Toolbox¡±. This toolbox is aimed for solving pressing needs for the video analysis of music-related body motion since video source recorded by regular video camera is a very good option for studying motion. The term music-related body motion refers to all sorts of body motion found in music performance and perception. It has received a growing interest in music research and behavioral science over the last decades. Particularly, with the rapid development of modern technology, various motion capture systems make it possible to further study music-related body motion. Matlab has been chosen as the platform since it is readily available, and there are already several pre-existing toolboxes to build on. This includes the ¡°Motion Capture (MoCap) Toolbox¡± [1] developed for the analysis and visualization of Motion Capture data, which is aimed specifically for the analysis of music-related body motion. The ¡°Music Information Retrievel (MIR) Toolbox¡± [2] is another relevant toolbox, which is developed for the extraction of musical features from audio data and the investigation of relationships between sound and music features. While the two above mentioned toolboxes are useful for studying motion capture data and audio, respectively, they are very differently designed, and it is not possible to make combined analysis of audio and motion capture data. Furthermore, there is no integration with video analysis. The MG Max toolbox [3] has been developed for music-related video analysis in the graphical programming environment Max/Msp/Jitter, with a number of novel visualization techniques (motiongrams, motion history images, etc.). These techniques are commonly used in music research, but are not currently available in Matlab. The main contributions of this project consist of two following things. One is to integrate the MoCap toolbox and MIR toolbox, and provide simple preprocessing on different input data. Another is to provide several video analysis techniques to study music-related body motion in the toolbox. These video analysis techniques include motiongram, optical flow, eulerian video magnification. With these techniques, the developed MG toolbox for Matlab could provide reliable and quantitative analysis of music-related body motion based on video.
