For 9 or more instrumentalists.
At the beginning of the piece, each player independently chooses one of the event nodes in the interior of the larger circle. This is the only ring of event nodes that does not have a rotating attack cursor, the absence of which denotes silence.
In their own time, each player independently decides when to move to another event node. All moves must be to event nodes that are connected by a line. Once on a ring other than the center, a series of attack cursors will cross each event node. Each time an attack cursor crosses a player's active event node, play a short sonic event. If the attack cursor has a red arc following it, sustain that event for the duration of the arc (until the end of the red arc has passed through the active event node).
Each player should spend at least 15-20 seconds on each event node before moving on. While on an event node, a player's sound should stay consistent. A new sound can be introduced upon arrival at a new node. These sounds need not be predetermined.
Variations: Prior to performance the ensemble can collectively decide a) what each performer will play, and to adhere to this throughout the duration of the piece, b) that each concentric circle denotes a specific pitch/sonic event, or c) ?????
Duration: 10 minutes or more.
