Influence of attack parameters on the playability of a virtual bowed string instrument

In this paper, we test the hypothesis proposed in a companion paper submitted to this conference (see [SS00]), namely that the playability of a bow stroke can be fully described by three parameters- bow velocity, bow position and bow force. Moreover, the envelope of these parameters influences the quality of the attack. In this paper, we present a novel technique for measuring parameters of bowing. By coupling a haptic display to a computational model of a bowed string, we simulate the normal and frictional forces present during bow-string interaction.
