Place 8 speakers in a circle around the audience. Play the 8 channel recording (contact me to obtain a copy). Each singer should stand next to one speaker. The singers should concentrate on full awareness of the sound coming from each speaker, unconcerned with classification of pitch or timbre, but rather simply observing. After the crotale strike at 4 minutes, 28 seconds, each singer should begin to sing the sound she or he hears coming from his or her speaker.
Continue until the sound stops.
