In this demo, a new application for the wireless sensor networks (WSN) is presented. This is the first time WSN is used to in the music field, where the music is being manipulated and changed according to the movement of the dancer. Twenty-three tmote sensors have been deployed on a dancing stage, and two sensors were attached to the arms of each dancer. Information collected from sensors deployed on the stage are being sent and processed at a central location where the music being played is manipulated. This project is the first phase of collaboration in a multi-disciplinary research between the Computer Science department and the College-Conservatory of Music at the University of Cincinnati.
