概要

We explored how a pianist manipulates his upper body according to his interpretation of music. We asked a professional pianist to perform artistic, deadpan, and exaggerated renditions of two structurally contrasting pieces. The pianist's affective interpretations clearly differentiated among the three renditions. The artistic rendition, representing the true nature of the piece, was compared to the contrived deadpan and exaggerated renditions. The pianist's range of body movement in the artistic rendition differed from the other two for a fast, energetic piece, whereas it only differed from the deadpan for a slow, romantic piece. The pianist highlighted the structural contrasts within the artistic rendition by manipulating his range of body movement and by coordinating the variations between body movement and temporal/dynamical projection of tones.
