Abstract:

This paper considers the problem of simulating Jazz improvisation and accompaniment. Unlike most current approaches, we try to model the musicians' behavior by taking into account their experience and how they use it with respect to the evolving contexts of live performance. To represent this experience we introduce the notion of Musical Memory, which exploits the principles of Case-Based Reasoning (Schank & Riesbeck 1989). To produce live music using this Musical Memory we propose a problem solving method based on the notion of PACTs (Potential ACTions) (Ramalho & Ganascia 1994b). These PACTs are a generic framework for representing the musical actions that are activated according to the context and then combined in order to produce notes.
