LP-22: Differentiating the Pitch Bend Function Between the Sitar as a Real and Virtual Instrument

Suhit Chiruthapudi

Abstract: The pitch bend is used as a tool in a virtual instrument/synth that allows one to glide smoothly from one note to another. Almost all virtual instruments today employ the pitch bend joystick/wheel on a keyboard to solely manipulate the fundamental frequency or the pitch of the note being played. While this feature allows a perceptually realistic reproduction of slides in a few instruments, it largely fails to do so with plucked string instruments, especially non-Western traditional instruments. In this abstract, I chose to study the meend technique in Sitar performance in order to understand in finer detail the factors (including, but not limited to, the fundamental frequency) that characterize the glide between two notes.
