  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.

  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.
