Abstract

In this paper, we describe a multi-level approach for the extraction of instrumental gesture parameters taken from the characteristics of the signal captured by a microphone and based on the knowledge of physical mechanisms taking place on the instrument. We also explore the relationships between some features of timbre and gesture parameters, taking as a starting point for the exploration the timbre descriptors commonly used by professional musicians when they verbally describe the sounds they produce with their instrument. Finally, we present how this multi-level approach can be applied to the study of the timbre space of the classical guitar.
