Cage began as an acolyte of Arnold Schoenberg. In 1935 and 1936 he attended several of the great man’s classes at USC and UCLA. His attempts at twelve-tone writing were peculiar, featuring rows of up to twenty-five notes. From the start, he expressed disdain for the conventions of mainstream classical music and looked around for alternatives. In 1930, when he was only eighteen, he made a trip to Berlin and received stimulation from the culture of the Weimar Republic. He happened to attend a “phonograph concert” presented by Paul Hindemith and Ernst Toch, at which phonographs played prerecorded sounds onstage, including a “spoken music” of phonetic syllables. In 1939 Cage wrote a work in which a phonograph becomes a musical instrument—Imaginary Landscape No. 1, for muted piano, Chinese cymbal, and variable-speed turntables. Three years later came Credo in Us, which includes a part for a record player or radio; the score suggests, with apparent sarcasm, that the operator “use some classic: e.g. Dvořák, Beethoven, Sibelius, or Shostakovich.”
For Cage, the classical tradition was worn-out kitsch ripe for de-construction, in the manner of his intellectual hero, the conceptual artist Marcel Duchamp. A record player squawking random bits of Beethoven or Shostakovich became the sonic equivalent of painting a mustache on the Mona Lisa or displaying a urinal as sculpture.
Also, Cage loved noise. In a 1940 manifesto he declared, “I believe that the use of noise to make music will continue and increase until we reach a music produced through the aid of electrical instruments which will make available for musical purposes any and all sounds that can be heard.” He made his name as a composer for percussion, manufacturing instruments from brake drums, hubcaps, spring coils, and other cast-off car parts. At the same time, he was bewitched by soft sounds, rustlings on the border between noise and silence. The prepared piano, his most famous invention, never fails to surprise listeners expecting to be battered by some unholy racket; the preparation process, involving the insertion of bolts, screws, coins, pieces of wood and felt, and other objects between the strings, is conceptually violent, but the sounds themselves are innately sweet. Cage’s prepared-piano pieces—among them The Perilous Night, Daughters of the Lonesome Isle, and the cycle Sonatas and Interludes—have some of the supernatural poignancy of Erik Satie, whose music Cage loved from an early age.
The same gentleness governs the String Quartet in Four Parts (1949–50), whose movements are titled “Quietly Flowing Along,” “Slowly Rocking,” “Nearly Stationary,” and “Quodlibet.” Underneath the ethereal surface, however, unsettling new processes are at work. In the quartet Cage gathers various kernels of musical sound and arranges them in a “gamut,” a kind of chessboard of possibilities. He moves from one sound to another in a detached frame of mind, trying not to push them where they do not want to go. This abdication of control sets the stage for an enormous shock.
When Cage heard Boulez’s Second Sonata, he was, in his own words, “stupefied by its activism, by the sum of the activities inherent in it.” In his next works, Sixteen Dances and the Concerto for Prepared Piano and Chamber Orchestra, everything disintegrated. At first, Cage maintained the method of the String Quartet in Four Parts, making moves on a chart of sixty-four sounds, containing notes, chords, trills, and so on. Then, while writing the final movement of the Concerto, in late 1950 and early 1951, the composer began tossing coins in order to determine what should come next. He followed the rules of the Chinese divinatory practice of the I Ching, or Book of Changes, which uses random operations to generate any one of sixty-four hexagrams, each describing a different state of mind or being (“force,” “radiance,” and so on). The piano cycle Music of Changes, composed in 1951, depended on the I Ching throughout; successive coin tosses determined what sound would be heard, how long it should last, how loud it should be, what tempo should be observed, and how many simultaneous layers of activity should accumulate. When the process called for maximum density, Cage wrote down what he acknowledged to be an “irrational” quantity of notes, leaving the execution to the performer’s discretion.
Half the sounds on the charts were, in fact, silences. As James Pritchett writes in a study of Cage’s music, the composer was becoming interested in the “interchangeability of sound and silence.”
The use of chance—Cage would later make musical decisions based on imperfections in manuscript paper, star charts, and computer-generated numbers—strayed far outside European classical tradition. By downtown New York standards, however, it was nothing terribly outlandish. In these years Jackson Pollock, Willem de Kooning, Franz Kline, Barnett Newman, Mark Rothko, and Robert Rauschenberg were throwing down violent swirls of paint, stark monochrome patterns, and shiny geometric lines, or making canvases entirely black or entirely white. Pollock’s “drip paintings” used a semi-chance process.
Cage consorted with the painters, following them from the Artists’ Club on East Eighth Street to the Cedar Tavern. He also worked in tandem with Merce Cunningham, who had created the role of the Revivalist in Martha Graham’s Appalachian Spring and later devised his own joltingly free and fluid choreographic language. Together, Cunningham and Cage invented a new kind of chance-driven dance in which sound and movement went their separate ways only to meet up again on a deeper conceptual level. Around this time, Cage browsed through the literature of Zen Buddhism, which supplied him with an all-accepting, “whatever happens will happen” approach to the creative process.
A few other New York–based composers were thinking along similar lines, and they gravitated into Cage’s orbit. The most important of these was Morton Feldman, a New York native who had steeped himself in Bartók, Varèse, the Second Viennese School, and Abstract Expressionist painting. It was Feldman who set loose the imp of chance; one day at Cage’s apartment he offered up for inspection a draft of a piece titled Projection 1, whose score consisted not of notes on staves but of a grid of boxes, each box lasting a certain period of time and indicating a high, middle, or low range. This novel practice came to be known as graphic notation: the composer was no longer telling performers exactly which notes to play at any given time.
A laboratory atmosphere developed in Cage’s apartment. Other frequent visitors were the teenage experimental prodigy Christian Wolff, whose early works drew on severely limited gamuts of three or four pitches; Earle Brown, whose open-form pieces imported some of the energy of bebop; and the pianist David Tudor, whose realizations of his friends’ graphic and chance scores were compositions in themselves.
Cage launched his revolution at three historic concerts in the spring and summer of 1952. First came Water Music, at the New School for Social Research, in May. David Tudor not only played the prepared piano but shuffled cards, poured water from one receptacle to another, blew a duck whistle, and changed stations on a radio. Each action was plotted on a time continuum. Then came Black Mountain Piece, at Black Mountain College, the first true “happening.” The boundary between artist and audience disappeared as participants stepped out of the crowd to perform musical or extramusical actions. Martin Duberman, in his history of the college, valiantly tried to determine what happened at the happening, but no two accounts agreed. Cage lectured on Zen Buddhism, perhaps standing on a ladder. Robert Rauschenberg exhibited artworks and/or played Edith Piaf records at double speed. Merce Cunningham danced. David Tudor played prepared piano. Movies of some kind were shown, boys or girls served coffee, a dog may or may not have barked. Black Mountain had always been a haven for adventurous spirits, but some of the faculty felt that Cage had gone too far. Stefan Wolpe, who had gone through his own Dada phase in 1920s Berlin, walked out in protest.
The final breakthrough was the premiere of 49330, the so-called silent piece, on August 29, in the upstate New York town of Woodstock. Cage later said that he had been inspired to write 49330 after seeing a group of all-white Rauschenberg canvases at Black Mountain the previous year. “Music is lagging,” he thought to himself, on encountering Rauschenberg’s work. In fact, he had already experimented with spells of silence in Music of Changes, and, back in 1948, he had talked about writing a four-and-a-half-minute soundless piece titled Silent Prayer. Rauschenberg simply emboldened him to do the unthinkable.
