A Component Model of Gestural Primitive Throughput

This paper suggests that there is a need for formalizing acomponent model of gestural primitive throughput in musicinstrument design. The purpose of this model is to construct acoherent and meaningful interaction between performer andinstrument. Such a model has been implicit in previous researchfor interactive performance systems. The model presented heredistinguishes gestural primitives from units of measure ofgestures. The throughput model identifies symmetry betweenperformance gestures and musical gestures, and indicates a rolefor gestural primitives when a performer navigates regions ofstable oscillations in a musical instrument. The use of a highdimensional interface tool is proposed for instrument design, forfine-tuning the mapping between movement sensor data andsound synthesis control data.
