Sound is constant. Perception is context.
The composer chooses a theoretical setting in which sounds are arrayed as they occur in perceptual consciousness and sets them in motion. Patterns, therefore, are not established beforehand, but are the result of fluidity and juxtaposition as the work progresses. This is listening, and hearing, as it takes place outside the context of "music", its paradigms, and its arrangements.
