then stretches of silence (e.g. five to fifteen seconds).
Variation 1: Without saying so, pick another player and use the same densities she does.
Variation 2: Mentally pick another player and use the opposite densities that he does: when he is ‘flurrying’, you play sparsely.
Variation 3: Switch back and forth at will between playing independently, playing the same density as another player, and playing the opposite densities.
Variation 4: Make some of the notes of altered timbre, i.e. extended techniques.
Variation 5: Switch back and forth at will between your main instrument, your voice, and some kind of percussion (body, room, found, or small percussion instrument).
Variation 6: Add one or two percussionists who ignore the flurries and keep a steady beat.
Variation 7: One player at a time who ignores the flurries (but listens to the percussion, if present) and plays a long, lyrical line.
