The aim of this work is to provide jugglers with gestural control of music. This is based on the willing to control music by recy- cling mastered gestures generated by another art. Therefore we propose the use of a gestural acquisition system based on the processing of the electromyographic signal. The recordings are done during a three-ball cascade, of electromyogram from chosen muscles, which play a specific role in the juggling gesture. Processing of those signals is proposed in order to control musical events by means of parameters related to juggling gesture.
