Before Ornette Coleman arrived at the Five Spot Café in November 1959, he had spent years being turned away. In Los Angeles, where he’d moved in 1952 after growing up in Fort Worth, Texas, he worked as an elevator operator while studying music theory from books. When he showed up to jam sessions, the other musicians threw him out. They said he didn’t know how to play. They said his intonation was wrong. They said he was changing the chord changes to something unrecognizable.

They were right about the last part. Coleman wasn’t playing the chord changes because he had decided the chord changes were not where the music lived anymore. He had arrived, through years of self-teaching and what he would later call “harmolodic” theory, at a different idea: that melody could generate its own harmonic logic, that rhythm could be free without being formless, that jazz could move forward only by abandoning the system that had produced bebop’s most dazzling achievements.

The jazz world was not ready to hear this. But it was about to.

The Shape of Jazz to Come

In 1959, Coleman recorded The Shape of Jazz to Come for Atlantic Records. The album did not sound like its title — it did not sound like a manifesto or a theoretical statement. It sounded like a band playing with a freedom and urgency that was almost physical. Don Cherry on cornet, Charlie Haden on bass, Billy Higgins on drums. The compositions had memorable melodies, blues feeling, a directness that sat oddly alongside the harmonic liberation underneath them. Something was wrong — or rather, something was different — in a way that was immediately apparent and impossible to explain.

That November, Coleman’s quartet took up a two-month residency at the Five Spot in New York. The jazz world showed up every night. Not all of it was convinced. Miles Davis, who was at the peak of his own considerable powers — Kind of Blue had come out earlier that year — heard Coleman and delivered what may be the most compressed critical verdict the music ever produced: “He just came and f**ked up everybody.” Miles meant it, at least partly, as a complaint. Coleman, he felt, didn’t know how to play. Leonard Bernstein, the classical conductor, heard Coleman and declared him a genius. Trumpeter Roy Eldridge was skeptical: “I think he’s jiving, baby.”

The disagreement was the point. Coleman’s music was dividing the jazz world into people who heard liberation and people who heard chaos, and the argument those two camps had with each other produced the most fertile period in the music’s history since bebop.

What Free Jazz Actually Was

The term came from Coleman’s 1960 album Free Jazz: A Collective Improvisation, recorded on December 21 of that year with a double quartet — eight musicians improvising simultaneously for nearly forty minutes, with only loose pre-composed themes as guideposts. The experience of listening to it is still disorienting sixty-five years later. The musicians don’t take turns. They don’t trade fours. They talk over each other, interrupt each other, follow each other into territory that no chart could have mapped.

Coleman had intended “free jazz” as simply an album title. He was uncomfortable with it becoming a genre name, and with good reason: the label suggested formlessness, when what he was actually interested in was a different kind of form. “Although they were freeing up certain strictures of bebop,” the guitarist Marc Ribot observed later, Coleman and Albert Ayler “were in fact each developing new structures of composition.” The freedom was freedom from specific conventions, not freedom from structure altogether.

What free jazz gave up was functional harmony — the system of chord changes that had organized jazz from its beginning — in exchange for what one writer called “a far-ranging, stream-of-consciousness approach to melodic variation.” This was not nothing. It was a complete reimagining of how improvised music could be organized. And it pulled the music back, paradoxically, toward older, pre-jazz forms: the field hollers, street cries, and work songs that had preceded the whole European harmonic apparatus that bebop had pushed to its limit.

The Fallout

By 1961, John Coltrane — who had sat in with Coleman’s group, studied his approach, and been changed by it — was beginning his own journey toward the outer limits of the music. His 1965 album Ascension, a large-ensemble collective improvisation, was the most direct acknowledgment of what Coleman had set loose. Albert Ayler was going further still, stripping jazz down to something closer to folk music heard through a fever dream. Cecil Taylor was building a piano vocabulary that had nothing to do with the harmonic tradition and everything to do with density, weight, and the physical impact of sound.

The critics who had dismissed Coleman found themselves outpaced by events. The musicians who had thrown him out of jam sessions were playing catch-up to an argument he had already moved on from.

What Remains

Ornette Coleman kept playing until near the end of his life in 2015. His 2006 album Sound Grammar won the Pulitzer Prize — making him only the second jazz musician to receive the honor, after Wynton Marsalis — and the music on it was unmistakably, irreducibly itself. The same plastic-horn feeling, the same blues roots, the same harmolodic logic that had gotten him thrown out of Los Angeles clubs in the early 1950s.

Miles Davis eventually absorbed elements of free jazz into his own music. The musicians who had laughed at Coleman in 1959 were playing his compositions by 1965. The Five Spot residency that had divided the jazz world became, in retrospect, a before-and-after moment — one of those rare events in which a musician simply insisted, through sheer force of musical conviction, that the future would sound different from the past.

It did. It still does.
