Abstract

Timbre is an integral dimension of musical sound quality, and people accumulate knowledge about timbre of sounds generated by various musical instruments throughout their life. Recent studies have proposed the possibility that musical sound is crossmodally integrated with visual information related to the sound. However, little is known about the influence of visual information on musical timbre perception. The present study investigated the automaticity of crossmodal integration between musical timbre and visual image of hands playing musical instruments. In the experiment, an image of hands playing piano or violin, or a control scrambled image was presented to participants unconsciously. Simultaneously, participants heard intermediate sounds synthesised by morphing piano and violin sounds with the same note. The participants answered whether the musical tone sounded like piano or violin. The results revealed that participants were more likely to perceive violin sound when an image of a violin was presented unconsciously than when playing piano was presented. This finding indicates that timbral perception of musical sound is influenced by visual information of musical performance without conscious awareness, supporting the automaticity of crossmodal integration in musical timbre perception.
