Pitch bends and tonguing articulation in clarinet physical modeling synthesis

A physical modeling approach is used to investigate playing effects in woodwind instruments. This builds upon prior work concerning both empirical studies of the acoustics of the clarinet and extensive development of computer simulations of musical instrument systems. Specifically, explicit implementations of two performance gestures for the clarinet are given and demonstrated: tonguing and pitch bending. Physical modeling for the clarinet is briefly reviewed. Following this we show how both tonguing and pitch bending map to changes in the clarinet physical model itself and in the control parameter data. To our knowledge, tonguing in particular is one effect that has not been widely discussed in the literature, at least in the exact form we present. Finally, some possible future research directions are indicated.
