"Voyage" is a piece for 4-track-tape, composed between November 1985 and August 1986 at CEMAMu (Centre d'Etudes de Mathematique et Automatique Musicale) in Paris, using the UP/C, a graphically oriented Computer system designed by lannis Xenakis.
In "Voyage", there is a concentration on continual transformations of all Parameters ofthe musical material; wave-forms, pitches, textures. For large sections of the piece there are five "voices", which are simlar but independent, and with rhythmic structures which are related to each other with the proportions 9:10:11:12:13. In the spatial projection, the four channels are divided into “left" and "right", each side being in Stereo (i. e. "front" and "back"). The “final mix" of the piece only occurs in the concert hall, when the fusion ofthe rhythmic cycles and harmonic evolution ofthe voices, which are separated into two channeis (two Stereo channels) on the tape, is achieved. This effect is most evident in the opening and closing sections, but is still present in the middle sections which are more texturatiy complex and the voices less distinct.
