Alvin Lucier is an American composer of experiemntal music and sound installations that explore acoustic phenomena and auditory perception. Much of his work is influenced by science and explores the physical properties of sound itself: resonance of spaces, phase interference between closely tuned pitches, and the transmission of sound through physical media.
The composer and his critics count his 1965 composition Music For the Solo Performer (above) as the proper beginning of his compositional career. In that piece, EEG electrodes attached to the performer’s scalp detect bursts of alpha waves generated when the performer achieves a meditative, non-visual brain state. These alpha waves are amplified and the resulting electrical signal is used to vibrate percussion instruments distributed around the performance space.
Vespers (1968), in which performers use hand-held echolocation devices to locate the approximate physical center of a room, to deepen their understanding of acoustical perception, and to reveal the elements of environmental space through non-visual means.
I Am Sitting in a Room
One of Lucier’s most important and best-known works is I am sitting in a room (1969), in which Lucier records himself narrating a text, and then plays the recording back into the room, re-recording it. The new recording is then played back and re-recorded, and this process is repeated. Since all rooms have a characteristic resonance (e.g., between a large hall and a small room), the effect is that certain frequencies are gradually emphasized as they resonate in the room, until eventually the words become unintelligible, replaced by the pure resonant harmonies and tones of the room itself.
Other key pieces include North American Time Capsule (1966), which employed a prototype vocoder to isolate and manipulate elements of speech; Music on a thin wire (1977), in which a piano wire is strung across a room and activated by an amplified oscillator and magnets on either end, producing changing overtones and sounds; Crossings (1982), in which tones play across a steadily rising sine wave producing interference beats; Still and moving lines of Silence in Families of Hyperbolas (1973–74), in which the interference tones between sine waves create “troughs” and “valleys” of sound and silence; and Clocker (1978), which uses biofeedback and reverberation.
