But during the last thirty years, scholarly and scientifc research has fo-cused increasingly on the visual aspects of music performances, i. e. on the percep-tion of the musician’s body in action. This article provides a basic overview of recent empirical studies on this topic. Visual aspects of music performances can be differ-entiated into bodily gestures that produce sounds and those who serve as means of nonverbal communication. The article discusses interactions on the level of visual and auditory perception, which reveal details about the multisensory aspects of mu-sic performances. The results can not only be of use for performers but also push us to rethink our conception of music itself.
