New Orleans Jazz

1900s–1920s · New Orleans, Louisiana

The music that became jazz: collective improvisation on a brass-band structure, born in Storyville and the second-line parades, carrying everything that followed in its DNA.

New Orleans jazz emerged from the specific cultural conditions of New Orleans: a city with a large Creole community, an active tradition of French-language music and Catholic culture, an annual Mardi Gras that required bands, a brass-band funeral tradition that required different music going to the cemetery (solemn) and coming back (joyful), and, from 1897 to 1917, the Storyville red-light district where musicians were employed continuously.

The music’s structural breakthrough was collective improvisation: three voices — cornet (melody), clarinet (countermelody above), trombone (bass voice below) — improvising simultaneously against a rhythm section. This polyphonic ensemble style gave New Orleans jazz its characteristic texture: busy, conversational, layered, with no single voice dominating.

The key figures were Buddy Bolden (the first bandleader credited with playing jazz, though no recordings survive), King Oliver (the dominant cornet voice of the 1910s), Sidney Bechet (soprano saxophone, the music’s most extravagant melodist), Jelly Roll Morton (its first composer-theorist), and above all Louis Armstrong, who left New Orleans for Chicago in 1922 and transformed the collective tradition into something centered on the soloist.

The New Orleans style persisted in the “trad jazz” and Dixieland revival movements that appeared in the 1940s and continued through the twentieth century. It remains the foundational form: everything in jazz descends from it.

Ragtime

1897–1917 · genre

The first Black popular music form with a broad white audience: Scott Joplin's syncopated piano compositions gave American music its characteristic lilt and made 'rag' a synonym for modernity.

New Orleans jazz took ragtime's syncopated rhythmic language and transferred it from composed piano pieces to improvising ensembles.

The modern Black sacred music built by Thomas A. Dorsey from spirituals and blues technique — the training ground for soul and for half the great voices of American popular music.

The Baptist and sanctified church music of New Orleans Black communities contributed rhythmic energy and a devotional intensity to jazz's emotional vocabulary.
