Gesture-based human-robot Jazz improvisation

We present Shimon, an interactive improvisational robotic marimba player, developed for research in Robotic Musicianship. The robot listens to a human musician and continuously adapts its improvisation and choreography, while playing simultaneously with the human. We discuss the robot's mechanism and motion-control, which uses physics simulation and animation principles to achieve both expressivity and safety. We then present a novel interactive improvisation system based on the notion of gestures for both musical and visual expression. The system also uses anticipatory beat-matched action to enable real-time synchronization with the human player. Our system was implemented on a full-length human-robot Jazz duet, displaying highly coordinated melodic and rhythmic human-robot joint improvisation. We have performed with the system in front of a live public audience.
