Jazz: How a New Orleans Sound Became America's Original Art Form

The Intersection Where Jazz Was Born

At the corner of Canal Street and North Rampart in New Orleans stands Congo Square, where enslaved Africans gathered on Sunday afternoons throughout the eighteenth and early nineteenth centuries to sing, drum, and dance under one of the few local laws that permitted such gatherings. Scholars consider Congo Square one of the essential incubators of American vernacular music — the place where African rhythmic traditions survived intact long enough to merge with European harmonic structures, Protestant hymns, and the blues of the Mississippi Delta. From that collision emerged jazz, which Duke Ellington would later call America's only original art form.

New Orleans and the First Jazz Generation (1890–1920)

Jazz emerged in the late nineteenth century from the specific cultural conditions of New Orleans: a majority-Black and Creole population with a tradition of public music-making, a licensed red-light district called Storyville where musicians found steady employment, and a city saturated with brass-band parade music. Cornetist Buddy Bolden, active from around 1895 to 1907 before mental illness ended his career, is widely cited as the first jazz bandleader — though no recordings exist. Jelly Roll Morton, who claimed (with characteristic modesty) to have invented jazz in 1902, did leave recordings that document the music's early sophistication: ragged syncopated rhythms, blues inflections, and improvised melodic embellishment over composed chord changes.

The Original Dixieland Jass Band made the first commercially released jazz recording in 1917 — a fact complicated by the band being white, when the music's creators were overwhelmingly Black. Their record sold over a million copies and introduced jazz to audiences far beyond New Orleans. The Great Migration, which brought hundreds of thousands of Black Southerners north to Chicago, New York, and other cities between 1910 and 1940, carried jazz musicians and their music with them.

The Swing Era (1930–1945)

The Great Depression paradoxically accelerated jazz's commercial spread through the radio and recording industries. Big bands — ensembles of 12 to 20 musicians organized into brass, reed, and rhythm sections — replaced small combos as jazz's dominant format. Benny Goodman's 1938 Carnegie Hall concert, broadcast on radio and later released as a record, is often cited as the moment jazz received full mainstream cultural legitimacy. Count Basie's Kansas City orchestra and Duke Ellington's Cotton Club band developed swing styles that blended danceable rhythms with sophisticated harmonic writing.

Major Jazz Eras and Their Defining Characteristics

Louis Armstrong and the Primacy of Improvisation

Louis Armstrong, who traveled from New Orleans to Chicago in 1922 to join King Oliver's Creole Jazz Band, transformed jazz from a collective improvisation tradition into a soloist's art. His Hot Five and Hot Seven recordings of 1925–1928 established the extended solo as jazz's primary vehicle of expression and set a technical standard — range, speed, and melodic invention — that shaped every subsequent trumpeter. Armstrong's 1923 solo on Chimes Blues with King Oliver's band is considered the first recorded jazz solo of major significance.

Bebop and the Intellectual Turn (1944–1955)

In the early 1940s, a group of younger musicians began gathering after hours at Harlem clubs — notably Minton's Playhouse — to develop a style that deliberately excluded casual listeners and dancers. Alto saxophonist Charlie Parker and trumpeter Dizzy Gillespie worked out what became bebop: breakneck tempos, complex substituted chord changes, and improvised melodies that bore little surface resemblance to the original theme. The intention was in part artistic — pushing the music's boundaries — and in part social, asserting jazz as a serious art form rather than entertainment.

• Parker's 1945 recordings for Savoy Records, including Ko-Ko and Billie's Bounce, are considered bebop's founding documents.
• Bebop's rejection of dance rhythms permanently separated jazz from pop music, beginning a long decline in jazz's commercial dominance.
• Thelonious Monk's highly individualistic piano style — angular melodies, unexpected harmonic turns, deliberate use of dissonance — influenced virtually every jazz pianist who followed.

Miles Davis and Constant Innovation

Miles Davis had the unusual distinction of being central to at least four major jazz transformations. He led the nonet sessions released as Birth of the Cool in 1957 (recorded 1949–50) that defined cool jazz. His 1959 album Kind of Blue introduced modal jazz — improvising over scales rather than chord changes — and remains the best-selling jazz album of all time, with estimated sales over five million copies. His 1970 album Bitches Brew fused electric instruments, studio editing, and rock rhythms into jazz fusion and alienated a substantial portion of his existing audience in the process. He regarded the alienation as confirmation he was moving forward.

• Kind of Blue was recorded in two sessions totaling nine hours, with minimal rehearsal — most musicians saw the music for the first time on the day of recording.
• Davis's quintets of the mid-1960s, featuring Wayne Shorter, Herbie Hancock, Ron Carter, and Tony Williams, are considered among the most innovative small-group jazz on record.

Jazz Today

Contemporary jazz defies easy categorization. Artists like Kamasi Washington blend jazz with gospel, soul, and hip-hop influences and release records that reach streaming audiences in the millions. Robert Glasper's crossover work between jazz, R&B, and hip-hop earned multiple Grammy Awards and placed jazz musicians in recording sessions with Kendrick Lamar, Common, and Erykah Badu. Abroad, Norwegian and Scandinavian labels like ECM Records have developed a distinctly spare, melodic jazz aesthetic with global influence.

Best-Selling Jazz Albums of All Time

Jazz's story is one of continuous reinvention by musicians who found the conventions of previous generations too limiting. Each new style provoked controversy — bebop was called noise by swing fans, free jazz was called chaos by bebop fans — and each became in time a recognized tradition worthy of preservation and study. The argument about what jazz is has never been settled, which may be the best possible evidence that the music remains alive.
