Program notes:

This is a piece about silence and quasisilence and no silence, about tension and distention, about one movement.
A number of processes, that are no more than progressions between two opposed points, appear both in the global duration of the piece, and also compressed in small fragments: from no continuity to continuity, from "dissonance" to "consonance", from "soli" to "tutti", from imitation to reverberation, from low to high register, from fast to slow tempi. The form results from a constant game between the different levels of energy like the duration of a phrase, the expression of extreme registers, the stability or instability of a texture or even the process itself.
