Alvin Lucier • 1990 • Crossings. Three Works for Classical Instruments and Oscillators

This CD offers three significant electro-acoustic works by Lucier which explore interference or wave-beating effects between acoustic instruments and electronic oscillators. «In Memoriam Jon Higgins» for clarinet in A and slow-sweep pure wave oscillator (1984), played here by Thomas Ridenour, has an oscillator which changes pitch every 30 seconds while a clarinet tone is held for a full minute. The interference of these close pitches causes the psychoacoustic illusion of the tones spinning across the room. 'Septet for Three Winds, Four Strings and Pure Wave Oscillator' (1985), performed here by The New World Consort of Wesleyan Universiy, is in four sections with the grouping of the instruments and the microtonal movements changed for each section. Fascinating beat patterns result. With 'Crossings', composed in 1982, for a small orchestra of 16 players equally divided on either side of the stage, and a slow-sweep pure wave oscillator that slowly ascends throughout the entire seven octave range of the orchestra, Lucier creates a beautiful and peacefulness inducing illusion. During the oscillator's ascent, the instrumentalists, cued by video monitors, catch onto and hold a particular pitch, before, during, and after that same pitch is played from the oscillator. As the pitches slowly move toward each other, you can hear the beat of the frequencies slow down until reaching a steady pitch with no beating, instruments and electronics in exact unison. Then the beating speeds up again as the oscillator moves away from the instrument's pitch. For all their directness and apparent simplicity, Lucier's works provide an elegant listening experience.
