Yambu

Descarga is the Cuban tradition of extended, largely improvised jam sessions built on Afro‑Cuban dance grooves and montuno vamps. Emerging in 1950s Havana and later flourishing in New York, it brought the spontaneity of jazz to Cuban popular forms such as son, mambo, and chachachá. Typically recorded by all‑star studio ensembles, descargas feature rotating solos over repeating guajeos (ostinatos), anchored by the clave and a driving percussion section. They are celebratory, high‑energy gatherings where arrangers set up simple harmonic frameworks and horn "moñas" (riffs), then let the players stretch out.

Rumba cubana is an Afro‑Cuban secular music and dance tradition born in the working‑class solares and dockyards of Havana and Matanzas in the late 19th century. It is percussion‑driven, sung in call‑and‑response, and danced in a highly interactive way. The genre revolves around the rumba clave (in 3‑2 or 2‑3 orientation), interlocking conga (tumbadora) parts, wooden sticks (palitos) on the drum shell, and often cajones (wooden boxes) and chekeré. Its main substyles are yambú (slow and graceful), guaguancó (medium tempo, playful “vacunao” courtship gesture), and columbia (fast, often in 12/8, originally a solo male competitive dance). Rumba cubana is distinct from the ballroom “rhumba.” It is a community practice that blends Central/West African rhythmic logics with Spanish song poetry, improvisation, and dance theater.
