Study no. 15a.1 is 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 30 players [clapping and vocalizing].
The score should be projected on the floor, with performers arranged around the circle, standing or sitting in front of their assigned event node. If it is not possible to project on the floor, the score can be projected on a screen or wall, with players facing the screen in a circular formation. In both cases, audience members may be inside or outside the circle.
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 made one full revolution. Pitch and dynamic envelope are open.
One vocalization suggestion is that each performer 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.
Duration: 10 minutes or more.
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.
