Francois Bayle, "Vibrations Composees"

Vibrations Composees
35'58 -- 1973

First series rosace 1 -- respiration -- rosace 2 -- texture -- rosace 3
Second series rosace 4 -- polyrythmy -- small polyphony -- rosace 5



Some motions of vibrations can be organically linked to produce compositions of forces, morphodynamic singularities beneath the threshold of the audible. There results from this a special, intense type of audition which attends carefully to the palpitations of the material, its emotivity, its "respiration", its "texture", the movement of its patterns. This is the basis of the progression, an increasing step by step richness, of the short compositions called "rosaces". In effect it is a matter of attaining, through successive stages of auditive adaptation, the central experience of the last "rosace" -- the fifth -- which presents itself as the core of the composition, the heart of the organism. Meanwhile various interjected digressions and departures offer us imaginary breathings, textures, polyrhythms, small polyphonies.
One gets a sense of perspective: the trajectory is temporarily suspended at the center of its spiral (rosace 5).
Beyond, for a later time, a larger polyphony...
(There is now a distance between the two separate pieces, which were formerly joined: they must be visited separately).
The listener is urged to pick out the vocabulary of "dynams".
* The two pieces share a repertory consisting of:
isolated instrumental notes or sound objects linear extensions of thin sounds -- lines deployed in fanlike or whiplike formations
* as opposed to more elaborate formations:
colored masses of rustlings -- muted or scanning rhythms -- veiled songs - chaotic fragments that gradually become organized or, on the contrary, stuck regularities that dissolve into drifting smoke - streams of points that wrap themselves around motifs.

First series premiered on February 12, 1974 at the Espace Cardin in Paris. The full composition
premiered on october 15, 1974 in the main amphitheatre of the Sorbonne in Paris.
