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.

Brass band refers to ensemble-driven music performed primarily by brass instruments and percussion, with a sound characterized by powerful, blended timbres, antiphonal choirs, and a strong emphasis on melody and counter-melody. In its most codified form (the British-style brass band), the ensemble uses cornets, flugelhorn, tenor horns, baritones, euphoniums, trombones, tubas, and percussion, all written in transposed parts to create a homogenous, organ-like sonority. Repertoire spans marches, hymn tune settings, operatic and orchestral transcriptions, original contest works, and light music. Globally, the term also encompasses regional traditions such as New Orleans parade/second-line bands (merging ragtime, early jazz, and funk), and Balkan Romani brass bands (fast dance meters and virtuosic ornamentation), showing the format’s adaptability across cultures and celebrations.

Klezmer is the traditional instrumental music of Ashkenazi Jews from Eastern Europe, originally performed by itinerant bands for weddings and communal celebrations. It is characterized by expressive, voice-like ornamentation (krekhts, slides, trills), flexible phrasing, and a repertoire of dance forms such as freylekhs, bulgar, sher, khosidl, and horas. Modal color is central: the freygish (Ahava Rabbah/Phrygian dominant) and Mi Sheberakh (Ukrainian Dorian) modes are common, lending the music its plaintive, celebratory, and at times bittersweet sound. Typical ensembles feature clarinet or violin as lead, with tsimbl (hammered dulcimer), accordion, trumpet/trombone, bass, and later American additions like piano and drum set. While rooted in Jewish liturgical and Hasidic song, klezmer absorbed 19th‑century European social dances (polka, waltz, mazurka) and Balkan/Romanian influences (notably the free-rhythm doina), producing a flexible style that moves from rhapsodic improvisation to propulsive dance tunes.
