Music and Motion——How Music-Related Ancillary Body Movements Contribute to the Experience of Music

EXPRESSIVE PERFORMER MOVEMENTS IN MUSICAL performances represent implied levels of communication and can contain certain characteristics and meanings of embodied human expressivity. This study investigated the contribution of ancillary body movements on the perception of musical performances. Using kinematic displays of four clarinetists, perceptual experiments were conducted in which participants were asked to rate specific music-related dimensions of the performance and the performer. Additionally, motions of particular body parts, such as movements of the arms and torso, as well as motion amplitudes of the whole body were manipulated in the kinematic display. It was found that manipulations of arm and torso movements have fewer effects on the observers' ratings of the musicians than manipulations concerning the movement of the whole body. The results suggest that the multimodal experience of musicians is less dependent on the players' particular body motion behaviors than it is on the players' overall relative motion characteristics.
