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.

A virtuosic regional shamisen style from the Tsugaru area of Aomori, Japan, tsugaru-jamisen is known for its driving rhythms, percussive bachi (plectrum) strikes, and improvisatory development over folk-song (min'yō) melodic cells. Players typically use a futozao (thick-neck) shamisen with a large bachi, exploiting the instrument’s sawari (sympathetic buzz) and powerful downstrokes to create both pitch and percussion. Core repertoire pieces such as Tsugaru Jongara-bushi, Tsugaru Yosare-bushi, and Tsugaru Aiya-bushi are treated as frameworks for variation, with free-rhythm introductions blossoming into fast, dance-like sections. The style balances raw intensity and lyricism, combining rapid tremolo, slides, pull-offs, and offbeat accents with the Japanese jo–ha–kyū sense of pacing. It is performed solo, in duo call-and-response with singers and flutes, or in ensembles, and today appears in concert halls, festivals, competitions, and cross-genre collaborations.
