Abstract
Bowed string sound synthesis has long relied on physical modelling techniques; the achievable realism and flexibility of gestural control are appealing, and computational cost is increasingly manageable as technology has improved. A bowed string is simulated in two polarisations by numerically solving the partial differential equations governing its behaviour, using the finite difference method; a globally energy balanced scheme is used, as a guarantee of numerical stability under highly nonlinear conditions. In the vertical polarisation, a nonlinear contact model is used for the normal forces exerted by the bow hair, left hand fingers, and fingerboard. In the horizontal polarisation, a forcevelocity friction curve is used for the resulting tangential forces in the other polarisation. The scheme update requires the solution of two nonlinear vector equations; iterative methods (in this case, the NewtonRaphson method) are employed. Sound examples and video demonstrations are presented.
