Visual Perception of Performance Manner in the Movements of Solo Musicians

The study of music perception has focused almost exclusively on sound, ignoring the role of seeing the performer's body movements. Whilst anecdotes frequently refer to the importance of the performer's movements, there is scant psychological evidence to support this finding. The closest equivalent work in visual event perception research has shown that covert mental dispositions (for instance, an intention to deceive an observer) are specified in body movements, and therefore provide important information for the observer.. With these findings in mind, this article investigates the information conveyed by the movements of a musical performer when s/he is asked to play-the same piece in three different expressive manners. These performance manners are presented to observers in three modes: vision alone, sound alone and sound and vision together to investigate the relative contributions of the different perceptual modes. The results reveal that not only is vision a useful source of information about manner, but that it actually more clearly specifies manner than the other modes. These findings emphasise the need to consider visual as well as sound information in psychological enquiries into music perception.
