Casting is a real-time composition for a single performer using the Microsoft Kinect and Kyma. The piece embodies both the programmatic and the magical use of the term. By giving form to gesture that conjures sound and visual elements, a body’s movement becomes intertwined with the visceral. The performer’s body ‘throws’ and controls sound, enabling the viewer to perceive sound as transfigured by motion. In this way, music becomes defined by the human mold of the performer and listener.
