  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.

  Several empirical studies have investigated the role of tempo on the characteristic non-isochronous long–short duration pattern on eight note level in jazz. Friberg and Sundström (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)–that 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–that is, a medium/long–short–medium/short–long 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 & Sundström. (1997). Preferred swing ratio in jazz as a function of tempo.

  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 ± 4.39 years, 1.73 ± 0.04 m, mean ± SD), and 5 men (29.67 ± 4.63 years, 1.81 ± 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.

  Can we better understand the complex process of human music perception through a standardisation of the quantification of involuntary correspondences between motion and music? Exploring the frequency-domain and time-domain links between sound and motion signals in a systematic manner might encourage international and interdisciplinary collaboration, boosting developments in the field and knowledge transferability.
