Latin jazz is a fusion of jazz harmony and improvisation with Afro–Latin American rhythms, song forms, and percussion. It combines the swing, bebop, and big-band traditions with clave-based grooves such as son, rumba, danzón, and mambo, and later integrates Brazilian feels like samba and bossa nova. Typical features include the use of the clave (2–3 or 3–2), piano montunos (guajeos), bass tumbao patterns, timbales cáscara, conga marcha, and call-and-response horn "mambo" figures. While the rhythm section locks into cyclical patterns, soloists improvise using the vocabulary of jazz, creating music that is both danceable and harmonically rich.

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.

Danzón is a refined Cuban dance-music genre that emerged in the late 19th century and became the island’s national dance. It is characterized by an elegant, measured tempo, a promenading introduction called the paseo, and a succession of graceful, melodically rich themes. Rhythmically, danzón is anchored by Afro-Cuban syncopations such as the tresillo and the cinquillo, articulated by güiro and timbales (paila) over a steady bass. Traditionally performed by charanga ensembles—featuring wooden flute, violins, piano, string bass, güiro, and timbales—the style epitomizes salon sophistication while retaining a distinctly Afro-Caribbean rhythmic identity.

Habanera is a Cuban song-and-dance genre that emerged in Havana in the 19th century, written in duple meter and defined by a distinctive syncopated rhythmic cell often described as a tresillo with an added backbeat (frequently felt as a 3–3–2 grouping across the bar). Typically moderate in tempo and frequently set in a minor key, habaneras combine European salon-song harmony with Afro-Cuban rhythmic sensibility. The style flourished both as a vocal strophic canción with romantic or nostalgic lyrics and as an instrumental dance form for piano and small ensembles. Its characteristic lilt and sensual sway made it an international craze by the late 19th century, permeating opera, art song, and popular music across Europe and the Americas.
