a surround choral performance piece | cycles per second by revolutions per minute
“CPS / RPM” is a surround choral performance piece, exploring the basic elements of music: pitch (cps, Hertz) and rhythm (rpm, beats), as seen through a telescope, to a magnifying glass.

Meaning ‘cycles per second’ by ‘revolutions per minute’, the piece is anchored by a metronome, pulsing at quarter note = 60, and a choral pulse of A(440Hz) that rotates the audience in clockwise motion.  A double choir  of constancy and patterns is employed to create a harmonic math rhythm complex, where the relationship to the pulse is what breathes.  Cycles come in and out of focus, as akin to the nature of events, time, and life.
