Abstract
It is difficult problem to make a human like ensemble system. In this research, we analyzed the rhythm interaction between performers by measure the hutting time and hitting cycle of keyboard performance. From the analysis, we discovered importance of two effects, which are hitting lag and hitting lag variation between performers. We modeled its dynamics by non-linear phase oscillator, which has two kinds of interaction mechanism, which represents the effect from hitting lag and the effect from hitting lag variation. We evaluated this system with human performer and discovered that the coupling constant of each model determine the dynamics of performance and the balance of these two interactions is important to realize human like ensemble. Finally we show the best parameters of the models and realize human like ensemble system.
