Multiple similarly tuned snare drums are placed around a space with their snares turned off. A single snare drum in the center is amplified and begins to feedback on itself.

One by one, the other drums have their snares switched on so that the resonance of the first drum infects an increasing number of drums, causing them to resonate and rattle in sympathy with the first drum.

These sounds build up, interfere with each other, dissipate, and recompose, culminating in a single assemblage of sound and rhythm.
