Jazz accordion is a jazz practice that features the accordion—either piano accordion or chromatic button accordion—as a principal improvising and comping instrument. It adapts swing-time phrasing, bebop vocabulary, and modern jazz harmony to the bellows-driven mechanics of the accordion. The right hand typically carries melodic lines and solos, while the left hand provides bass motion and harmonic support, either via the traditional stradella bass system or a free-bass system that enables walking bass and rootless voicings. In European contexts the style often draws on musette waltzes and Parisian café idioms; elsewhere it readily blends with tango, Latin, and chamber-like small-group settings. The result ranges from fleet, guitar-like single‑note runs and elegant chord‑melody textures to luminous, reed‑choir timbres—capable of both lively swing and intimate, lyrical ballad playing.

Tango is a song-and-dance music from the Río de la Plata region, crystallizing in Buenos Aires (Argentina) and Montevideo (Uruguay) in the late 19th century. It is characterized by a melancholic, dramatic tone; richly expressive melodies; and a distinctive rhythmic feel rooted in the habanera and milonga. Core ensembles feature bandoneón, violin(s), piano, double bass, and sometimes guitar, forming the famed orquesta típica. Across the 1920s–1950s it became a worldwide craze, moving from rough immigrant bars to grand salons and radio, developing highly sophisticated arranging and performance practices. Lyrics often employ lunfardo (Buenos Aires slang) and dwell on urban nostalgia, love, betrayal, and the neighborhood (el barrio). Note on terminology: in flamenco, “tangos” is a distinct palo (song form) with a lively 4/4 compás, often in A Phrygian, closely related in feeling to rumba flamenca. Although it shares the name and a spirited character, flamenco tangos is a different tradition from the Río de la Plata tango described above.
