Study no. 15a.2 s part of a series of animated scores that use convergence to indicate attack times. This animated notational approach is complemented with a rotating attack cursor to indicate vocalization.
For 23 players [clapping and vocalizing].
Players should stand facing the projected score, arranging themselves relative to their assigned event node.
Each time a red circle converges on a player's event node, clap once. Clap quality (loud, quiet, flat, cupped, etc.) should be varied often.
Each time a small circle appears at 12 O'Clock on a player's respective circle and begins to rotate, sing a tone until it has completed one full revolution. Pitch and dynamic envelope are open.
One vocalization suggestion is that each player pick a pitch that is not already being sung, start quietly, crescendo to MF by 6 O'Clock, and decrescendo to nothing by 12 O'Clock. Other versions can be determined before performance. Use 'ah' or 'oh'. Pitch should not change during a revolution, but may change on subsequent revolutions.
Percussion instruments may be substituted for clapping.
If possible, the animated score should be projected for both the performers and audience to see. If this is not possible, one or more monitors can be used.
