The Creative and Scientific Legacies of Iannis Xenakis: International Symposium

Guelph/Waterloo/Toronto, Canada, 8-10 June, 2006

Iannis Xenakis (1922-2001) is a unique figure in contemporary music, not
only for the iconoclastic nature of his music but also for the scientific
attitude he brought to his work. His training as a civil engineer, his
experience as an architect, as well as his immersion in ancient Greek
philosophy, have all shaped his approach to developing a new theoretical
foundation of music and a style built from a unique set of compositional
techniques. His music and thought have proven highly influential, although
his work has been studied in detail by only a few. At the same time, some
have gone on to develop extensions to his theories and techniques.

The aim of this international symposium is to gather researchers and
artists/composers who consider their work to form part of Xenakis.s
legacy, either creative or scientific. In addition, joint sessions are
planned to bring together researchers from the music field with those in
science (Perimeter Institute for Theoretical Physics) and mathematics
(Fields Institute for Research in Mathematical Sciences).

This Symposium is being held in conjunction with soundaXis (1-11 June,
2006), a festival where, among much else, a number of compositions by
Iannis Xenakis will be performed at various venues in and around Toronto
by the leading new music ensembles of the region. [see
