Cajun is the dance-driven traditional music of the Francophone Cajuns of south Louisiana, characterized by driving two-steps, lonesome waltzes, and heartfelt, often nasal-tinged vocals sung in Cajun French and English. Its core sound blends button accordion and fiddle, propelled by guitar, bass, and the metallic pulse of the triangle (tit-fer). Built for social dancing in packed halls, the music emphasizes strong melodic hooks, call-and-response refrains, and sturdy rhythms. Repertoires include up-tempo two-steps in duple meter and lyrical waltzes in triple meter, with instrumental breaks that showcase the accordion’s bellows phrasing and the fiddle’s double-stops and slides. Over time, Cajun incorporated elements from country, blues, and swing while retaining a distinct regional identity.

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.
