Expressive musical re-performance is about enabling a person to experience the creative aspects of a playing a favorite song regardless of technical expertise. This is done by providing users with computer-linked electronic instruments that distills the instruments' interface but still allows them to provide expressive gesture. The next note in an audio source is triggered on the instrument, with the computer providing correctly pitched audio and mapping the expressive content onto it. Thus, the physicality of the instrument remains, but requires far less technique. We are implementing an expressive re-performance system using commercially available, expressive electronic musical instruments and an actual recording as the basis for deriving audio. Performers will be able to select a voice within the recording and re-perform the song with the targeted line subject to their own creative and expressive impulse.
