Ritmo en el corazón

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.

Guaguancó is a vibrant couple-dance style within the Cuban rumba family that emerged in working‑class Afro‑Cuban neighborhoods, especially in Havana and Matanzas. It features an interlocking percussion ensemble, call‑and‑response vocals, and a flirtatious dance whose central dramatic gesture is the vacunao, a playful, sudden pelvic or hand "tag" that the partner attempts to block. Musically, guaguancó is organized around the rumba clave (in 3‑2 or 2‑3 orientation), with layered patterns on congas (tumbadoras), the lead quinto drum improvising over the groove, and timekeeping on claves and a wooden guagua/cata. The singing typically begins with an improvised diana (vocal fanfare), moves into solo verses (pregón) and a catchy coro (estribillo). The overall effect is communal, earthy, and intensely rhythmic—designed as much for dance and social play as for musical display.

Guaracha is a fast‑paced Cuban song–dance genre known for witty, satirical, and often picaresque lyrics delivered over a driving Afro‑Cuban groove. It typically uses the son clave (in 2–3 or 3–2 orientation), call‑and‑response coros, and a lively montuno section that invites dance and audience participation. Originally tied to popular and comic theater, guaracha later became a staple of Cuban conjuntos and charangas, and it survives in the salsa repertoire as a label for brisk, upbeat numbers. Instrumentation commonly includes voice(s), guitar or tres, bass, bongó, maracas, claves, and often trumpets or charanga flute/violins. Harmonies are straightforward and bright (major keys, I–IV–V with frequent secondary dominants), while the rhythmic feel is relentlessly syncopated and festive. The term should not be confused with modern "guaracha edm" (a separate, contemporary club style); historical Cuban guaracha is a distinct traditional genre with roots in 19th‑century Havana and theatrical culture.
