New Orleans jazz is an early jazz style that emerged in New Orleans as small ensembles blended African-American musical practices with European instrumentation. It is characterized by collective improvisation, where multiple frontline instruments (typically cornet/trumpet, clarinet, and trombone) improvise simultaneously around the melody. Rhythm is driven by a steady, marching-band-derived pulse and syncopation, often supported by tuba (or string bass), banjo (or guitar), drums, and sometimes piano. The repertoire commonly draws on blues, ragtime, marches, quadrilles, hymns, and popular songs, with frequent use of call-and-response phrasing and a strong sense of swing that predates later big-band styles. In many catalogs this tradition overlaps with what is later called Dixieland, though historically it includes both African-American New Orleans styles and subsequent revival interpretations.

Ragtime is an African American–rooted piano style that flourished from the 1890s to the 1910s, characterized by lively syncopation in the right hand against a steady, march-like “oom‑pah” accompaniment in the left hand. Typically written in 2/4 or 4/4 time and notated with straight (unswung) eighth notes, classic rags unfold in multiple 16‑bar strains, often in the form AABBACCDD. The music draws on cakewalk rhythms, marching-band forms, and popular song, and it became a sensation through sheet music, piano rolls, and parlor performance. Scott Joplin, known as the “King of Ragtime,” helped codify the genre’s refined, compositional approach, calling for moderate tempos and a clear, singing melody. Beyond solo piano, ragtime was arranged for small ensembles and orchestras, found a home in vaudeville and dance halls, and laid essential groundwork for early jazz, stride piano, and much of 20th‑century American popular music.
