Experimental

A tradition of refusing tradition, where prepared pianos, tape loops, graphic scores, and sheer noise have spent eight decades asking what counts as music and never settling on an answer.

The Sound of the Question

Experimental music has no fixed instrumentation, no characteristic rhythm, no hometown. What holds it together is method: treating composition as inquiry rather than expression, prioritizing process over known forms. John Cage, in his 1955 essay “Experimental Music,” defined it as actions whose outcome is not foreseen. That definition still works.

Concrete Beginnings

The first rupture came from Paris. On October 5, 1948, Pierre Schaeffer, an engineer at Radiodiffusion-Television Francaise, broadcast his Cinq etudes de bruits on French radio. The opening piece, Etude aux chemins de fer, was built from recordings of trains. Schaeffer used turntables with locked grooves to loop sound fragments, speed controls to alter pitch, and a mixing board to layer recordings. He called it musique concrete: music from recorded sound rather than written notation. By the early 1950s, Schaeffer and Pierre Henry had moved to magnetic tape, cutting and splicing with a razor blade. Every sample-based music that followed descends from that studio.

In Cologne, Karlheinz Stockhausen took the opposite approach at the Westdeutscher Rundfunk studio, generating sound from scratch with sine-tone oscillators, pulse generators, and filtered white noise. His Gesang der Junglinge (1956) fused electronic tones with the recorded voice of twelve-year-old Josef Protschka singing from the Book of Daniel, spatialised across five channels. Stockhausen had proposed it as an electronic Mass for Cologne Cathedral; the Church refused, but the piece merged the French and German schools into something neither had imagined.

Cage and the Prepared Piano

John Cage arrived at his inventions through practical constraints. In 1940, working as a dance accompanist at the Cornish School in Seattle, he needed percussion sounds but had only a piano. He wedged screws, bolts, rubber, and felt between the strings, transforming the instrument into a one-person gamelan. His Sonatas and Interludes (1946 to 1948) requires forty-five notes to be prepared with screws, bolts, fifteen pieces of rubber, four pieces of plastic, several nuts, and one eraser; setup takes two to three hours.

On August 29, 1952, pianist David Tudor sat at a Steinway in the Maverick Concert Hall near Woodstock, New York, closed the keyboard lid, and did not play for four minutes and thirty-three seconds. 4’33” consisted of three movements of silence. The audience heard wind in the first movement, rain on the roof in the second, and their own murmuring in the third. One local artist stood up and suggested driving these people out of town. Cage’s point: silence does not exist, sound is always present, listening itself is a creative act.

Fluxus and the Event Score

In 1961, Lithuanian-born art historian George Maciunas organized the first Fluxus events at the AG Gallery in New York. The movement counted Yoko Ono, Nam June Paik, La Monte Young, and George Brecht among its participants. Brecht developed the “Event Score,” written instructions anyone could perform. Ono created Voice Piece for Soprano in 1961: “Scream. 1. against the wind. 2. against the wall. 3. against the sky.” Her Cut Piece, first performed at the Yamaichi Concert Hall in Kyoto on July 20, 1964, invited audience members to cut away pieces of her clothing while she knelt silently. These were not concerts. They were propositions about what performance could be.

Drones, Deep Listening, and Graphic Scores

La Monte Young’s 1958 Trio for Strings is often cited as the first minimalist composition: sustained tones with no melody or conventional development. In 1962 he formed the Theatre of Eternal Music with Marian Zazeela, John Cale, and Tony Conrad, performing drone improvisations governed by strict rules about allowable intervals. From 1966 to 1970, Young and Zazeela maintained a continuous sound-and-light installation in their New York loft, the Dream House, living inside sine-wave frequencies and magenta light. Brian Eno called Young “the daddy of us all.”

Pauline Oliveros, a founding member of the San Francisco Tape Music Center, coined “deep listening” in 1988 after recording inside the Dan Harpole cistern in Port Townsend, Washington, a concrete tank fourteen feet underground with a forty-five-second reverb. Her practice distinguished between hearing (involuntary) and listening (conscious, directed), building a pedagogy around the difference.

Cornelius Cardew, who had studied under Stockhausen in Cologne, spent four years (1963 to 1967) creating Treatise, a graphic score: 193 pages of lines, circles, and geometric shapes with no conventional notation and no performance instructions. Musicians play it on any instrument, interpreting the visual forms however they choose.

Rock’s Outer Limits

Captain Beefheart’s Trout Mask Replica (1969) sits where experimental method meets rock instrumentation. Don Van Vliet composed the album’s interlocking polyrhythmic parts by banging them out on a piano he could barely play; drummer John French transcribed them for the band. The Magic Band then rehearsed at 4295 Ensenada Drive in Woodland Hills, California, for roughly eight months under conditions approaching confinement: little food, no outside contact, marathon sessions deep into the night. The result, recorded in under five hours with Frank Zappa producing, sounds like several songs played simultaneously in the same room.

No Wave and the Guitar Orchestra

In 1978, a five-night festival at Artists Space in New York featured ten post-punk bands rejecting mainstream rock and punk’s simplicity alike. Glenn Branca performed with Theoretical Girls. Within two years he was writing symphonies for massed electric guitars in alternative tunings, exploiting overtone collisions at high volume. At the 1981 premiere of Symphony No. 1, two guitarists were Thurston Moore and Lee Ranaldo, who formed Sonic Youth. In 2001 Branca conducted Symphony No. 13 for one hundred guitars at the base of the World Trade Center.

Noise and Beyond

In Tokyo, Masami Akita began recording as Merzbow in 1979, naming the project after Kurt Schwitters’ Dada installation Merzbau. His output exceeds five hundred releases on over a hundred labels, treating distortion, feedback, and electronic overload as primary material rather than byproducts to be suppressed.

The experimental impulse kept surfacing. Bjork built Medulla (2004) almost entirely from human voices, recruiting beatboxers Rahzel and Dokaka, Inuit throat singer Tanya Tagaq, Mike Patton, and the London and Icelandic choirs. Animal Collective recorded Merriweather Post Pavilion (2009) at Sweet Tea Studio in Oxford, Mississippi, layering Roland SH-2 and Juno-60 arpeggios into psychedelic pop with no guitar. Reed Ghazala discovered circuit bending by accident in the 1960s when a short-circuiting toy amplifier produced unexpected oscillations in his desk drawer; he turned it into a practice of opening battery-powered devices and bridging random circuit-board points with wire. No theory required.

Experimental music keeps returning to one proposition: the rules are optional, the instruments are negotiable, and the only requirement is willingness to find out what happens next.
