À propos de Bohor (1962) de Iannis Xenakis

Bohor is the last of the five electronic works composed by Iannis Xenakis at the studio of the Groupe de Recherches Musicales at the French Radio in Paris. It is also presented as the first piece conceived for eight channels. Relying on Xenakis's writings and interviews, and on documents and sketches located in the Xenakis Archives, this paper contextualises Bohor and provides elements of analysis on the relationship between music and the composer's graphic plan of the work. It also shows the many possibilities imagined by Xenakis over the years for the sound diffusion of Bohor.
