Abstract

In this article, we present and discuss timbre and sound morphology in live electroacoustic and instrumental music from a compositional standpoint. We approach interaction and convergence issues in live electroacoustic music, related to the idea of sound morphology, based on the undulatory and granular sound paradigms. In instrumental composition, we analyze instrumental synthesis based on frequency modulation so as to generate pitches and enable timbre interpolation. Timbre fusion is also addressed, based on concepts of jitter, permeability and timbre of movement (Bewegungsfarbe). For these purposes, some examples of our compositions are addressed to illustrate these sound properties. In order to analyze the generated timbres, we apply time-varying audio descriptors to reveal some characteristics of the generated timbres. We conclude by comparing the analyzed operations with the emerging form of these works considering both the micro and macro temporal aspects. This article is an extended version of the paper "Interaction, Convergence and Instrumental Synthesis in Live Electronic Music", presented on the 12th CMMR. (AU)
