New ensemble system based on mutual entrainment

Ensemble is a kind of cooperative musical performance between humans, and this kind of flexible cooperation cannot be observed between human and music machine. Thus, to realize human-like ensemble, the analysis of actual performance between humans is necessary. In this research, we constructed a new ensemble system based on mutual entrainment, which re-creates the human ensemble process. By comparing among the ensembles of humans, previous system and our system, we clarify the importance of interaction between performers. Finally, we advocate co-creation and its process to expand the previous communication between human and machine.
