Sound-Motion Bonding in Body and Mind
This chapter focuses on the links between sound and body motion in music. It can readily be observed that musical sound is produced by body motion and also triggers body motion in many contexts, meaning scholars have an inexhaustible supply of sound-motion bonding available for research. The main challenges here are to get an overview of the different kinds of sound-motion bonding at work in music, and to go deeper into the subjective experiences of sound-motion bonding. To this end, the chapter presents sound-motion bonding in a so-called motor theory perspective on perception, suggesting that whatever humans perceive of sound, motion, and/or visual features is spontaneously re-enacted in our minds, meaning active mental simulation of whatever it is that we are perceiving. This leads to the idea of sound-motion objects, entities that fuse sensations of sound and motion into salient and holistically perceived units in musical experience.
