Samba‑jazz is a Brazilian small‑combo style that fuses the propulsive, syncopated rhythms of samba with the harmony, form, and improvisational language of modern jazz (especially hard bop and cool jazz). It is typically more energetic and instrumental than bossa nova, emphasizing virtuosic interaction in piano‑trio and quartet/quintet settings. The drumming concept—pioneered by Edison Machado and others—moves the samba pulse to the ride cymbal and hi‑hat ("samba no prato"), while the bass suggests surdo patterns and the piano/guitar supplies rich jazz voicings. Heads are often concise, followed by swinging, straight‑eighth samba grooves under extended improvisations, and a tight return to the theme.

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.

Bossa nova is a Brazilian popular music style that emerged in Rio de Janeiro in the late 1950s, blending samba’s syncopated pulse with the harmonic sophistication and understated cool of jazz. It is characterized by intimate, almost whispered vocals; a nylon‑string guitar playing the distinctive batida (a gently syncopated, two-beat accompaniment); subtle, brushed percussion; and lush, extended jazz harmonies. The mood is relaxed, refined, and full of saudade—a bittersweet sense of longing—often evoking images of Rio’s beaches, nightclubs, and urban modernity.

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.

Experimental big band is a forward-looking offshoot of the jazz big band tradition that applies avant‑garde composition, free improvisation, and nonstandard orchestrations to the classic large‑ensemble format. While it often retains a core lineup of saxophones, trumpets, trombones, and rhythm section, it commonly expands the palette with woodwind doublings, strings, electronics, unconventional percussion, and voice. Harmony ranges from extended tonal and modal writing to polytonality and atonality, often employing quartal/quintal harmony, tone clusters, and timbral (color‑based) harmonies. Rhythm favors odd meters, polyrhythms, metric modulation, and groove/texture hybrids. Forms may be through‑composed, modular, or suite‑like, and pieces frequently integrate conducted or cued improvisation, graphic notation, and other experimental score practices. Rather than a single codified style, experimental big band functions as an umbrella for large ensembles that push beyond swing and post‑bop arranging by drawing on contemporary classical approaches, free jazz, minimalism, electronics, and global traditions.

Avant-garde jazz is a boundary-pushing current of jazz that privileges experimentation, collective improvisation, and timbral exploration over conventional song forms and chord progressions. It often uses atonality or loose tonality, extended instrumental techniques, shifting or absent meters, and open forms. Ensembles may emphasize texture and density as much as melody and harmony, drawing as readily from modern classical music and non-Western traditions as from blues and bebop. While sometimes intense or noisy, avant-garde jazz also embraces spaciousness and silence, allowing players to interact in real time without predetermined roles. The result is music that questions the limits of jazz itself, foregrounding sound, spontaneity, and social expression.
