Abstract
GENDY3 (1991), composed by Iannis Xenakis (1922-2001) with his computer program called GENDYN, is an example of rigorous algorithmic composition (RAC), not of a musical score but of the sounding end product itself. This paper explores the pitch structure of this composition with a self-written tool that implements the same algorithm as the composer's, but which is enriched by analytical procedures and graphical output. Some laws governing the ermergence of pitch are discussed which help to understand the configuration of pitch structures available to a Gendyn composition in general and to GENDY3 in particular. This discussion is hoped to help in better understanding the interdependency of algorithmic requirements and artistic freedom in the case of Xenakis' last electroacoustic project.
