  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.

  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.

  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.

  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 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.

  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.

  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.

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.

  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.

• Zelechowska, Agata (2017). Combining eye-tracking and motion capture to study human bodily micromotion in music perception. Show summary

  In order to understand how we perceive music, we should always consider that this process starts in our bodies being exposed to sound. Thus, the cognitive processing of sound cannot be treated as separate from the functioning of the body. During the last decades there has been a growing focus on embodied music cognition, and the role of the human body in both perception and production of music has been widely studied. However, not much research has been devoted to what we might call ¡°micromotion¡± of the human body in the musical context ¨C the tiniest, often involuntary and unconscious movements that occur during music listening. The human body is never completely still as there are many physiological processes that induce small-scale movement. The question, then, is whether such micromotion is altered when we are exposed to music? Here I would like to present my design of a set of small experiments that will shed some light on how human micromotion is influenced by musical sound. Methodologically, I will use a combination of motion capture and portable eye-tracking glasses. Each experiment will be designed to test a different subject, such as the differences between listening to music via headphones and via loudspeakers or the importance of the low-frequency region (bass sound) in inducing body movement. The aim of these small and exploratory studies will be to understand more about the effects of musical sound on human micromotion in particular and music cognition in general.

• Zelechowska, Agata (2020). Irresistible Movement: The Role of Musical Sound, Individual Differences and Listening Context in Movement Responses to Music. 07 Gruppen. Show summary

  This dissertation examines the phenomenon of spontaneous movement responses to music. It attempts to grasp and illustrate the complexity of this behaviour by viewing it from different perspectives. Unlike most previous studies on music and body movement, it places the focus on barely visible manifestations of movement, such that can happen when listening to music while standing still. The point of departure is a reflection on movement responses to music, and why such responses are considered a universal human phenomenon. This is followed by a discussion on different approaches to studying how music `inspires' movement, and an overview of different factors that can potentially contribute to the emergence of movement responses to music. The first goal of the empirical research is to verify the common conception that `music makes us move' and examine whether such a movement response can be involuntary. Three of the five included papers show that music can, indeed, make people move, even when they try to stand as still as possible. The second goal is to explore different factors that contribute to movement responses to music. Throughout the included papers, several topics are examined, including rhythmic complexity, tempo, music genres, individual differences, playback systems, and others. The theoretical chapters show how these topics fit into three broader categories of music experience components: music, listener, and context. Overall, the results suggest that several factors seem to increase movement responses to music: the clear underlying pulse in the sound stimuli, the rhythmic complexity, a tempo around 120 beats per minute, listening on headphones rather than speakers, and high empathy of the listener.While this dissertation leaves many questions open, its main contribution is in bridging some gaps in the literature on musicrelated body movement. It also broadens up the perspective on why, how, and when music moves us.
