  The TIME project: Timing and Sound in Musical Microrhythm (2017¨C2022) studied microrhythm; that is, how dynamic envelope, timbre, and center frequency, as well as the microtiming of a variety of sounds, affect their perceived rhythmic properties. The project involved theoretical work regarding the basic aspects of microrhythm; experimental studies of microrhythm perception, exploring both stimulus features and the participants¡¯ enculturated expertise; observational studies of how musicians produce particular microrhythms; and ethnographic studies of musicians¡¯ descriptions of microrhythm. Collectively, we show that: (a) altering the microstructure of a sound (¡°what¡± the sound is) changes its perceived temporal location (¡°when¡± it occurs), (b) there are systematic effects of core acoustic factors (duration, attack) on microrhythmic perception, (c) microrhythmic features in longer and more complex sounds can give rise to different perceptions of the same sound, and (d) musicians are highly aware of microrhythms and have developed vocabularies for describing them. In addition, our results shed light on conflicting results regarding the effect of microtiming on the ¡°grooviness¡± of a rhythm. Our use of multiple, interdisciplinary methodologies enabled us to uncover the complexity of microrhythm perception and production in both laboratory and real-world musical contexts.

  This paper reports on an experiment that investigated how guitarists signal the intended timing of a rhythmic event in a groove-based context via three different features related to sound-producing motions of impulsive chord strokes (striking velocity, movement duration and fretboard position). 21 expert electric guitarists were instructed to perform a simple rhythmic pattern in three different timing styles¡ª¡°laidback,¡± ¡°on-the-beat,¡± and ¡°pushed¡±¡ªin tandem with a metronome. Results revealed systematic differences across participants in the striking velocity and movement duration of chords in the different timing styles. In general, laid-back strokes were played with lower striking velocity and longer movement duration relative to on-the-beat and pushed strokes. No differences in the fretboard striking position were found (neither closer to the ¡°bridge¡± [bottom] or to the ¡°neck¡± [head]). Correlations with previously reported audio features of the guitar strokes were also investigated, where lower velocity and longer movement duration generally corresponded with longer acoustic attack duration (signal onset to offset).

  This article studies the rhythm of Norwegian telespringar, a tradition with an intimate relationship between music and dance that features a nonisochronous meter; that is, the durations between adjacent beats are unequal. A motion-capture study of a fiddler and dance couple revealed a long-medium-short duration pattern at the beat level in both the fiddler's and the dancers' periodic movements. The results also revealed a correspondence between how the fiddler and the dancers executed the motion patterns. This correspondence suggests that the performers share a common understanding of the underlying ¡°feel¡± of the music. The results are discussed in light of recent theoretical perspectives on the multimodality of human perception. It is argued that the special feel of telespringar derives from embodied sensations related to the dance and how music and dance have developed in tandem over time. The study advocates a holistic view of music and dance, the importance of insider experience, and the role of embodied experience in guiding our understanding of the music as such.

  Previous studies have revealed uneven duration patterns at the sixteenth note level of samba. In the present study, we investigated the influence of tempo on such sixteenth-note patterns in a performed samba groove.The results revealed an uneven duration pattern in all tempi. Interestingly, the shortest note becomes relatively shorter and the longest relatively longer as the tempo increases. We suggest that the differences in relative durations between tempi reflect the need to maintain the samba sixteenth note ¡®template¡¯ in all tempi: producing the samba ¡®feel¡¯ requires that relative durations have to be adjusted to tempo.

  The perception of musical meter is fundamental for rhythm production and perception in much music. Underlying structures such as pulse, meter, and metrical subdivisions are often described as successive points in time. This paper investigates whether experienced musical meter may not only include such points in time, but also trajectories between the points¨Cthat is, metrical shapes. Previous studies have pointed out that there seems to be a relationship between musical meter and periodic body motion like foot tapping, head nodding and dancing. This paper investigates musical meter in music styles with an intimate relationship with dance, and whether metrical points and trajectories can be understood by investigating performers¡¯ periodic body motion. Two motion capture studies form the empirical basis of this paper; first, a percussionist and a dancer performing Brazilian samba; second, a fiddler and two dancers performing Norwegian telespringar. The analysis showed that it seemed to be a relationship between the periodic fluctuation in audio amplitude and the performers¡¯ periodic foot motion on sixteenth note level in samba. Furthermore, motion analysis revealed similar periodic shapes in both percussionist and dancer foot motion. In telespringar there seemed to be a relationship between the metrical beat level and the fiddler¡¯s foot stamping. In addition, the beat duration pattern, as indicated by the fiddler¡¯s periodic foot stamping, seemed to correspond to the shape of the dancers¡¯ vertical body motion. The results support the view that there is a close relationship between musical meter and performers¡¯ periodic body motion. This suggest that the underlying meter may not only include metrical points in time, but that each metrical beat/subdivision duration has a corresponding metrical trajectory with a certain shape. If this is the case, then perceivers¡¯ and performers¡¯ implicit knowledge of the underlying reference structure in samba and telespringar might incorporate knowledge about the underlying metrical shape.

  The pulse level in music is often described as a series of isochronous beats that provides an underlying reference structure against which we perceive rhythmic patterns. This notion is challenged by music styles that seem to feature an underlying reference structure that consists of beats of uneven duration, such as certain traditional Scandinavian dance music genres in so-called asymmetrical meter. This study investigates periodic body motion as a reference structure in a specific style of traditional Norwegian dance music called telespringar. The intimate relationship between music and motion is often highlighted in rhythm studies of telespringar, so this study encompasses both sound and motion analyses. It is based on a motion capture study of three telespringar performers; one fiddler and two dancers. Motion analysis of the fiddler's foot stamping indicates a stable long¨Cmedium¨Cshort duration pattern at beat level. Motion analysis of the dancers' vertical motion of the hips revealed a periodic pattern in synchrony with the beat duration pattern determined by the fiddler's foot stamping. This result implies that the underlying rhythmic structures in telespringar depend upon a shared and embodied knowledge of the underlying asymmetrical reference structure that is implicit in the production and perception of telespringar.

  Recording music-related motions in ecologically valid situations can be challenging. We investigate the performance of three devices providing 3D acceleration data, namely Axivity AX3, iPhone 4s and a Wii controller tracking rhythmic motions. The devices are benchmarked against an infrared motion capture system, tested on both simple and complex music-related body motions, and evaluations are presented of the data quality and suitability for tracking music-related motions in real-world situations. The various systems represent different trade-offs with respect to data quality, user interface and physical attributes.

  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.

  Recent studies have revealed that systematic non-isochronous duration patterns on sixteenth note level in samba, seems to be a prominent feature of this style (e.g., Gerischer, 2006; Gouyon, 2007; Haugen and God?y, 2014; Naveda, 2011). Present study investigates the effect of tempo on the duration pattern on sixteenth note level in a performed samba groove. Some previous studies conducted in other genres have found that uneven duration patterns seem to become more even as tempo increases. It has been suggested that this effect might be due to perceptual constraints producing a lower limit for duration (e.g., Friberg and Sundstr?m, 1997) or a reduction of rhythmic categories when two initially uneven short notes become so similar in fast tempi that they merge into one single category (Clarke, 1985). Two samba performers from S?o Paulo in Brazil, a percussionist and a dancer, were recorded. The percussionist played a samba groove on a Brazilian hand drum called pandeiro and the dancer performed the dance in samba no p¨¦ style. The samba groove was performed at three different tempi: fast (133 bpm), preferred (100 bpm), and slow (69 bpm). The results are based on an analysis of the recorded sound. The temporal positions of the played sixteenth notes were detected using the MIRtoolbox (Lartillot and Toiviainen, 2007). The results show that all the sixteenth notes were significantly different in all tempi, suggesting a medium/long¨C short¨Cmedium/short¨Clong duration pattern. We found that the second sixteenth note becomes relatively shorter and the fourth relatively longer as the tempo increases. This is in contrast with previous research, which suggest that non-isochronous duration patterns become more even as tempo increases. We suggest that the non-isochronous duration pattern must become more pronounced when tempo increases in order to maintain the specific ¡®feel¡¯ of the samba groove. This implies that the duration pattern have to be consistent at a categorical level across tempi: the groove pattern is a pattern of duration categories and does not rely on fixed percentages or ratios. Future work will include more recordings in order to be able to draw more general conclusions.

  Several empirical studies have investigated the role of tempo on the characteristic non-isochronous long¨Cshort duration pattern on eight note level in jazz. Friberg and Sundstr?m (1997) found an approximately linear decrease of swing ratio with increasing tempo and suggest a lower limit to the duration of the short second eight note around 100 ms. Honing and Haas (2008) found that the swing ratio is adapted to the overall tempo, but did not find that it scaled linearly with tempo. Non-isochronous subdivision patterns have also been found in samba groove (e.g., Gerischer, 2006; Haugen, 2016; Naveda, 2011)¨Cthat is, at the level of sixteenth notes. In samba groove the fourth sixteenth note seems to be longer in duration than the others. The aim of this study is to investigate the influence of tempo on the duration pattern on sixteenth note level in a performed samba groove. Two professional samba performers, a percussionist and a dancer, participated in the study. The analysis in present paper is based on the recorded sound. The percussionist played a samba groove at three different tempi: 133, 100, and 69 BPM. Since all the sixteenth notes are played in this recording, their temporal position could be detected using onset detection. Subsequently, the inter-onset-intervals (IOIs) between the sixteenth notes were calculated and converted into percent values according to their percentage of the beat. The analysis showed significant differences between all the sixteenth note durations in all three tempi¨Cthat is, a medium/long¨Cshort¨Cmedium/short¨Clong duration pattern on sixteenth note level were found at all tempi. In addition, a significant interaction between sixteenth note type and tempo were found. The analysis showed that as the tempo increases the short second sixteenth note became shorter and the long fourth sixteenth note became longer. In the fastest tempo, the short second sixteenth note¡¯s mean duration is only 68 ms, something that is much shorter than 100 ms that has previous been suggested to be the shortest interval that we can hear and perform. The results suggest that the non-isochronous duration pattern on sixteenth note level in samba becomes even more non-isochronous with increasing tempo. In addition, the results indicate that the lower limit for IOIs in samba groove is below 100 ms. REFERENCES: Friberg & Sundstr?m. (1997). Preferred swing ratio in jazz as a function of tempo.

  The perception of musical meter is fundamental for rhythm production and perception in much music. Underlying structures such as pulse, meter, and metrical subdivisions are often described as successive mental beats. This paper investigates whether experienced musical meter may not only include such mental points in time, but also trajectories between the points¨Cthat is, metrical shapes. Previous studies have pointed out that there seems to be a relationship between musical meter and periodic body motions like foot tapping, head nodding and dancing. This paper investigates whether metrical shapes might also be present in performers¡¯ periodic body motions. Two motion capture studies form the empirical basis of this paper; first, a percussionist and a dancer performing Brazilian samba; second, a fiddler and two dancers performing Norwegian telespringar. Motion analysis of the samba performers¡¯ periodic body motion revealed similar periodic shapes in both percussionist and dancer foot motion on sixteenth note level. In telespringar there seemed to be a relationship between the beat durations indicated by the fiddler¡¯s periodic foot stamping and the shape of the dancers¡¯ vertical body motion. The results support the view that there is a close relationship between musical meter and performers¡¯ periodic body motion. The analysis of the performers¡¯ periodic body motions revealed periodic motion shapes on beat level in telespringar and on sixteenth note level in samba. This suggest that the underlying meter may not only include metrical points in time, but that each metrical beat/subdivision duration has a corresponding metrical trajectory with a certain shape. If this is the case, then perceivers¡¯ and performers¡¯ implicit knowledge of the underlying reference structure in samba and telespringar might incorporate knowledge about the underlying metrical shape.

  The MYO armband from Thalmic Labs is a complete and wireless motion and muscle sensing platform. This paper evaluates the armband¡¯s sensors and its potential for NIME applications. This is followed by a presentation of the prototype instrument MuMYO. We conclude that, despite some shortcomings, the armband has potential of becoming a new ¡°standard¡± controller in the NIME community.

  This thesis investigates the interaction between perceived rhythm and underlying reference structures in the experience of rhythm in music. The point of departure is that both music performers¡¯ and perceivers¡¯ body motions are relevant to the study of rhythm. The studies included in this thesis investigate rhythm patterns in sound and body motion in two music styles, Brazilian samba and Norwegian telespringar, based on motion capture and sound recordings of professional musicians and dancers. Samba is often characterized by so-called systematic microtiming at the sixteenth-note level. This was confirmed in our sound analysis of the samba groove, showing a medium¨Cmedium¨Cmedium¨Clong duration pattern at the sixteenth-note level. In addition, motion analysis of the percussionist¡¯s heel tapping and the dancer¡¯s steps revealed motion patterns in synchrony with this rhythm pattern. Telespringar, on the other hand, is often described as featuring a so-called asymmetrical triple meter¡ªthat is, the three beats in a measure are of uneven duration. According to previous studies, both the fiddler¡¯s foot stamping and the dancers¡¯ vertical body motions are related to this underlying meter. This relation was confirmed in the motion analysis of a fiddler¡¯s foot stamping. The dancers¡¯ vertical motion patterns, however, deviated from theories suggesting that the turning points in the dancers¡¯ vertical motion curves correspond to the meter. The thesis therefore suggests that it is the shape of the dancers¡¯ vertical motion that corresponds to the underlying beat duration, rather than the turning points that correspond to the underlying beat positions. The main conclusion is that the underlying sixteenth-note level in samba and the underlying beat level in telespringar should not be understood as deviations from an isochronous pulse of some sort. Instead, they should be understood as inherently (and necessarily) non-isochronous, in and of themselves.
