Whatever the sound may be, it carries with it the trace of a gesture. Intimately embedded within it is a direct or indirect relation with another or others. The force of sound is to be found precisely in the nuance carried by this gesture: the meaning of what is spoken (softly or violently), music interpreted more or less emphatically or functioning like the accelerator of a motorbike, ridden by an adolescent, screaming through the housing projects in the middle of the night… Examples of gestures to analyze, each with a nuance, from extreme gentleness to the violence of revolt. Somewhere between the very soft and the unbearably loud lies the perceptible, the making and the sharing of sonic matter. The fragility of exchange is at the center of the question of listening: listening is the place of access to the distribution of the sensible.
