Abstract
In music performance, performers don't communicate with only auditory cues (musical sound) but also visual cues. Previous research (Kawase et al., 2006) suggested that performers used various visual communication channels such as body movements and gaze directions. In this research, we focused on performers' visual cues, especially their body movements. We investigated which region of body was considered important to communicate. In addition, we investigated the position of performers at rehearsal and on live performance. This research will contribute to understanding of communication in music performance.
