Kendhang, Or and Vug: three works for performer and live computer system

Abstract

This paper outlines some of the technical and aesthetic issues arising from my works which involve computer technology directly in live performance. A process of experimentation in algorithmic composition is described, particularly in relation to aspects of form and ways of automating musical processes at various structural levels. Three works are then described: Kendhang is a work in which a dancer influences the output of a simple algorithmic music system based on interpolation; Or is an instrumental trio which uses realtime sound granulation; and Vug extends this realtime granulation and applies it to a solo clarinet line. An exploration of both the distinctions and similarities between these works is used to develop a general approach to the integration of computer-based algorithmic systems with live performance. This approach emphasises the need for efficient use of technological resources in order to convey expressive content accurately.
