Jazz is an improvisation-centered music tradition that emerged from African American communities in the early 20th century. It blends blues feeling, ragtime syncopation, European harmonic practice, and brass band instrumentation into a flexible, conversational art. Defining features include swing rhythm (a triplet-based pulse), call-and-response phrasing, blue notes, and extended harmonies built on 7ths, 9ths, 11ths, and 13ths. Jazz is as much a way of making music—spontaneous interaction, variation, and personal sound—as it is a set of forms and tunes. Across its history, jazz has continually hybridized, from New Orleans ensembles and big-band swing to bebop, cool and hard bop, modal and free jazz, fusion, and contemporary cross-genre experiments. Its influence permeates global popular and art music.

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.

Vintage jazz refers to the early styles of jazz that flourished from the 1910s through the 1930s, encompassing New Orleans/early hot jazz, classic blues, and the rise of swing-era dance bands. It emphasizes collective improvisation, call-and-response horn parts, two-beat and early swing feels, and repertoire drawn from blues, ragtime, and Tin Pan Alley standards. Instrumentation typically features cornet/trumpet, clarinet, and trombone as the front line, supported by a rhythm section of piano, banjo or early archtop guitar, tuba or acoustic bass, and drums. Performances often follow 12-bar blues and 32-bar AABA song forms, with head arrangements and short solos that serve the groove and the dance floor. Today, "vintage jazz" is also used to describe historically informed performance and recording approaches that recreate the sound and aesthetic of pre-bebop jazz—mono or minimally mic’d sessions, ribbon mic warmth, and arrangements that spotlight collective energy over virtuosic individualism.

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.
