Jazz fusion (often simply called "fusion") blends the improvisational language and harmonic richness of jazz with the amplified instruments, grooves, and song forms of rock, funk, and R&B. It typically features electric guitars, electric bass or fretless bass, Rhodes electric piano, clavinet, analog and digital synthesizers, and a drum kit playing backbeat- and syncopation-heavy patterns. Hallmarks include extended chords and modal harmony, complex and shifting meters, brisk unison lines, virtuosic improvisation, and a production aesthetic that embraces effects processing and studio craft. The style ranges from fiery, aggressive workouts to polished, atmospheric textures, often within the same piece. Emerging in the late 1960s and flourishing through the 1970s, jazz fusion became a bridge between jazz audiences and rock/funk listeners, shaping later styles such as jazz-funk, smooth jazz, nu jazz, and parts of progressive and technical rock/metal.

Brazilian jazz is the meeting point of Brazilian popular music and North American jazz, blending samba and bossa nova rhythms with jazz harmony, improvisation, and ensemble interaction. The style typically features syncopated Brazilian grooves (samba, bossa, partido‑alto) under extended jazz chord voicings and lyrical melodies. Acoustic guitar or piano often supplies a gently propulsive, off‑beat rhythmic bed, while bass and drums translate samba’s surdo and pandeiro patterns to the jazz rhythm section. Timbres range from intimate (nylon‑string guitar, brushed drum kit, flute) to expansive (full percussion batteries, horns, and electric keys). The overall feel can be both laid‑back and danceable—romantic yet harmonically sophisticated.

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.

Murga is a carnival-rooted performance genre that blends choral singing, sharp social satire, and highly rhythmic street percussion. Typically presented by neighborhood troupes, it combines theatrical staging, elaborate costumes, and choreographed movement with a driving, snare-led groove. Although it has variants across the Hispanic world, murga is especially associated with the Río de la Plata region, where its sound crystallized into massed chorus, rapid-fire "cuplés" (satirical couplets), and set pieces that open (saludo) and close (retirada) each show. The tone ranges from festive and humorous to bitingly political, all delivered with bold vocal projection and call-and-response energy.

Candombe is an Afro‑Uruguayan percussion tradition centered on the interplay of three barrel drums called tamboriles: chico (the high, time‑keeping drum), repique (the improvisatory, conversational drum), and piano (the deep, bass foundation). Played in a forward‑moving parade formation known as a cuerda de tambores, its groove is driven by a characteristic clave‑like timeline articulated on the shell (madera) and by the interlocking parts of the three drums. Beyond rhythm, candombe is a living cultural practice linked to Afro‑Uruguayan neighborhoods in Montevideo—especially Barrio Sur, Palermo, and Cordón—where comparsas (troupes) combine drummers, dancers, flag bearers, and emblematic characters (mamas viejas, gramilleros, and the escobero). While primarily percussive, modern song forms and fusions often add vocals, guitar, bass, and keyboards, projecting candombe into jazz, pop, and rock contexts while retaining its unmistakable swing and street‑parade energy.
