Human Bodily Micromotion in Music Perception and Interaction, 2012

“Human Bodily Micromotion in Music Perception and Interaction, 2012” sought to investigate the close couplings between musical sound and human bodily micromotion. Micromotion was here used to describe the smallest motion that we are able to produce and experience, typically at a rate smaller than 10 mm/s. The last decades have seen an increased focus on the role of the human body in both the performance and the perception of music. Up to now, however, the micro-level of these experiences has received little attention. This project investigated music-related micromotion of people experiencing music (perceivers), with an aim of contributing to knowledge about how musical sound influences human motion at the micro-level. This was based on literature studies, theoretical modelling, and a longitudinal observational study as well as three large-scale experiments of sound-motion relationships. The project also provided knowledge to a large, annotated and metadata-rich database of the micromotion recordings mentioned above. The database was central to the current project, and will be made available for future research in the field. Further, the project provided conceptual models and software tools for using micromotion to control musical sound in computer-based systems. Such musical microinteraction can be used for music performance or production, or for "active listening". The project was based on recent theories of embodied music cognition, combining musical phenomenology with new models from cognitive neuroscience. Methodologically, the project span widely, from introspection and discussion in small groups to statistical analysis of motion capture recordings and development of new interactive music systems.
