Abstract:

A commuted-synthesis model for bowed strings is driven by a separate nonlinear model of bowed-string dynamics. This gives the desirable combination of a full range of complex bow-string interaction behavior together with an efficiently implemented body resonator. A ``single-hair bow'' may control a pulsed-noise version which provide the effects of multiple bow hairs. The pulsed noise may also include qualitatively the impulse responses of commuted high-frequency body modes.
