Pure Noise

PAULINE OLIVEROS   November 1971

Group/Solo Activity
from Sonic Meditations

Sing the purest tone possible, that is, with the fewest partials, in a comfortable register. Gradually change the quality of this tone to include more and more partials until it approaches or becomes a noise band. Continue as long as possible, going from pure tone to noise band with each breath.

Variation: Reverse the above process.
