A Component Model of Gestural Primitive Throughput

This paper suggests that there is a need for formalizing a component model of gestural primitive throughput in music instrument design. The purpose of this model is to construct a coherent and meaningful interaction between performer and instrument. Such a model has been implicit in previous research for interactive performance systems. The model presented here distinguishes gestural primitives from units of measure of gestures. The throughput model identifies symmetry between performance gestures and musical gestures, and indicates a role for gestural primitives when a performer navigates regions of stable oscillations in a musical instrument. The use of a highdimensional interface tool is proposed for instrument design, for fine-tuning the mapping between movement sensor data and sound synthesis control data.
