Abstract This paper outlines a technique for generative musical accompaniment of a polyphonic audio stream. The process involves the real-time extraction of salient harmonic features and the generation of relevant musical accompaniment. We outline a new system for polyphonic pitch tracking of an audio signal which draws upon and extends previous pitch tracking techniques. We demonstrate how this machine listening system can be used as the basis for a generative music improvisation system with the potential to jam with a live ensemble without prior training.
