Repetition is based on body rhythms, so we identify with the heartbeat, or with walking, or with breathing.
Or the other process that is important is that I compress longer sections of composed music, either found or made by myself, to such an extent that the rhythm becomes a timbre, and formal subdivisions become rhythm.
Or in other works I have also projected the sound in a cube of loudspeakers. The sound can move vertically and diagonally at all speeds around the public.
One experiments and has to choose always the best results.
No, what is important is neither linearity or non-linearity, but the change, the degree of change from something that doesn't move to other events with different tempos in particular.
It is true that the eyes dominate the ears in our time.
