Salsa is a pan–Latin dance music forged primarily in New York City by Puerto Rican, Cuban, and other Caribbean diasporas. It synthesizes Afro‑Cuban rhythmic blueprints, Puerto Rican bomba and plena, jazz harmony, big‑band horn writing, and Nuyorican street culture into a tightly arranged yet improvisation‑friendly style. The music lives on the clave (either 2‑3 or 3‑2), with layered percussion (congas, bongó, timbales, cowbell, güiro, maracas), a tumbao bass that anticipates the beat, and piano montuno guajeos that interlock with the rhythm section. Call‑and‑response vocals (coro/pregón), punchy horn mambos and moñas, and instrumental solos energize the montuno section. Tempos range from medium to fast in 4/4, optimized for social dancing (commonly “on1” or “on2”). Across decades, salsa has branched into harder, percussion‑forward “salsa dura,” smoother “salsa romántica,” and regional scenes in Puerto Rico, Venezuela, and Colombia, while continuing to influence—and be influenced by—neighboring tropical and jazz idioms.

Chachachá is a Cuban dance‑music genre that emerged in early‑1950s Havana as a dancer‑friendly offshoot of danzón‑mambo. It is typically performed by charanga ensembles—flute and violins over piano, bass, güiro, and timbales—producing a light, elegant sonority distinct from the brass‑heavy mambo big bands. The groove is mid‑tempo with a clear, even pulse that supports the signature “cha‑cha‑chá” triple step heard in the dancers’ feet. Melodies are tuneful and diatonic, harmonies favor simple I–IV–V movements with occasional II–V turnarounds, and arrangements move from a lyrical cuerpo to a montuno section featuring coro‑pregón call‑and‑response, piano tumbao, and tasteful flute improvisations. The name “chachachá” is often traced to the shuffling sound of the dancers’ steps; composer‑violinist Enrique Jorrín simplified mambo syncopations to make the beat more square and intelligible, which helped the style spread worldwide through social and ballroom dance.

Latin (as a genre label) is a broad umbrella used by the recording industry to categorize popular music rooted in Latin America, the Caribbean, and the Iberian world, often characterized by syncopated Afro-diasporic rhythms, dance-forward grooves, and lyrics primarily in Spanish or Portuguese. As a marketplace category that took shape in the mid-20th century United States, it gathers diverse traditions—Afro-Cuban, Brazilian, Mexican, and Caribbean styles—into a shared space. In practice, "Latin" spans everything from big-band mambo and bolero ballads to contemporary pop, rock, hip hop, and dance fusions produced by artists of Latin American heritage.

Son cubano is a foundational Cuban genre that fuses Spanish-derived song forms and harmony with Afro-Cuban rhythms and percussion. Born in eastern Cuba (Oriente) and crystallized in Havana in the 1910s–1920s, it became the backbone of much of 20th‑century Latin popular music. Typical ensembles began as sextetos (tres, guitar, bongó, maracas, claves, and bass or marímbula) and later evolved into septetos with trumpet. Conjunto formats in the 1940s added piano, congas, and multiple horns. The music rides a son clave (in 3‑2 or 2‑3 orientation), features interlocking tres guajeos, a walking/tumbao bass that anticipates the downbeat, and call‑and‑response vocals in the montuno section. Harmonically it is rooted in I–IV–V with bluesy dominant sevenths and occasional secondary dominants. Lyrically it balances romance, everyday life, and streetwise wit, always aimed at dancing and social gathering.

Plena is an Afro–Puerto Rican music and dance genre that arose in working-class neighborhoods—most famously in Ponce and later Santurce—during the early 20th century. Often called the “periodical sung” (periódico cantado), plena songs chronicle everyday life, news, humor, and social commentary through concise verses and refrains. The core sound centers on panderos de plena (a family of frame drums in three sizes), the güiro scraper, handclaps, and call‑and‑response vocals. Rhythms are typically in 2/4 or 4/4 with syncopations related to Afro-Caribbean cells such as the habanera. While harmony is generally simple (I–IV–V with occasional modal color), plena’s power lies in its infectious groove, topical lyrics, and communal participation—qualities that later ensembles expanded with bass, brass (notably trombones), and dance-band arrangements.

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.
