Three works for classical instruments and oscillators (1982–1985). Lucier explains the process:
“The three works on this compact disk explore interference phenomena between sound waves. When two or more closely tuned tones are sounded, their oscillations periodically coincide to produce audible beats of sound. The speed of the beating depends upon the distances between the pitches of the sounds. The further apart, the faster the beating; at unison, no beating occurs. Furthermore, under certain conditions, the beats may be heard to spin around the room . . . ”
