Axé is a high-energy popular music from Salvador, Bahia, that fuses Afro-Brazilian and Caribbean rhythms with pop and rock songcraft. Designed for massive Carnival parades, it pairs large percussion ensembles with bright electric guitars, brass hooks, and call-and-response vocals to drive dancing crowds along the trio elétrico (truck-mounted sound stages). Grounded in afoxê/ijexá and samba-reggae grooves, axé favors upbeat major-key melodies, anthemic choruses, and lyrics celebrating joy, love, summer, Afro-Bahian pride, and the collective ecstasy of the street party. Its sound is at once percussive and melodic: layered surdos, timbales, repiniques, and atabaques interlock beneath catchy horn lines and pop arrangements built to move tens of thousands of revelers.

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.

Latin pop is mainstream pop music performed primarily in Spanish (and sometimes Portuguese) that blends contemporary pop songwriting with Latin American and Iberian rhythms, harmonies, and vocal stylings. It typically features verse–pre-chorus–chorus forms, catchy hooks, polished production, and a balance between rhythmic drive and romantic lyric themes. Classic Latin pop often leans on bolero- and ballad-informed melodies and soft-rock textures, while modern Latin pop readily incorporates dance-pop, electronic, and urbano elements (such as reggaeton-influenced grooves) without losing its sing-along pop core.

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.

Contemporary jazz is an umbrella term for post-1970s jazz that absorbs elements of post-bop, fusion, world music, modern classical, R&B, and electronic production. It retains jazz’s core values of improvisation, harmonic sophistication, and ensemble interplay while embracing new timbres, studio techniques, and rhythmic vocabularies beyond traditional swing. Depending on the artist or scene, contemporary jazz may sound acoustic and spacious (ECM-influenced), groove-oriented and electric (fusion-leaning), or harmonically dense and metrically adventurous (post-bop lineage). The result is a flexible, global-facing idiom that treats jazz as a living language, open to new influences, collaborations, and technologies.

Contemporary R&B is a sleek, modern evolution of rhythm and blues that fuses the emotive vocal traditions of soul and gospel with the songwriting immediacy of pop, the rhythmic vocabulary of hip hop, and polished electronic production. Its hallmarks include melismatic lead vocals, lush stacked harmonies, mid‑tempo grooves or slow jams built on drum-machine patterns and 808 bass, and sophisticated chord colors (maj7, min9, add9). The style spans tender ballads to club‑ready tracks, but consistently centers intimacy, romance, empowerment, and personal reflection in its lyrics. While rooted in classic R&B, it differentiates itself through contemporary sound design, hook‑driven structures, and production aesthetics shaped by post‑disco, boogie, quiet storm, and later hip‑hop and trap rhythms.

Dance-pop is a mainstream-oriented pop style built for both radio and the dancefloor. It blends hook-driven songwriting with club-ready rhythms, typically using a steady four-on-the-floor kick, bright synthesizers, and punchy, polished production. Tempos usually sit in the 110–128 BPM range, and arrangements emphasize memorable choruses, clear verses and pre-choruses, and concise structures suitable for radio edits. Compared with club genres like house or techno, dance-pop prioritizes song form, vocal presence, and accessible harmonies, while still retaining an energetic groove. The sound palette often includes layered synths, sampled or electronic drums, tight bass lines, ear-catching toplines, and modern production techniques such as sidechain compression and stacked vocal harmonies.

Disco is a dance-focused style of popular music that emerged in early-1970s urban nightlife, especially in New York City and Philadelphia. It is defined by a steady four-on-the-floor kick drum, syncopated hi-hats and handclaps, octave-jumping basslines, lush string and horn arrangements, and a glamorous, celebratory sensibility. Built for DJs and clubs, disco favored extended 12-inch mixes with breakdowns and build-ups that kept dancefloors moving. The sound drew from soul, funk, and Latin music, embraced orchestral textures, and became a cultural movement associated with Black, Latino, and LGBTQ+ communities before crossing over to mainstream pop by the late 1970s.

Electronic is a broad umbrella genre defined by the primary use of electronically generated or electronically processed sound. It encompasses music made with synthesizers, drum machines, samplers, computers, and studio/tape techniques, as well as electroacoustic manipulation of recorded or synthetic sources. The genre ranges from academic and experimental traditions to popular and dance-oriented forms. While its sonic palette is rooted in electricity and circuitry, its aesthetics span minimal and textural explorations, structured song forms, and beat-driven club permutations. Electronic emphasizes sound design, timbre, and studio-as-instrument practices as much as melody and harmony.

Euro house is a commercially oriented branch of house music that crystallized in continental Europe in the early 1990s. It blends the four-on-the-floor rhythms and club structure of house with the glossy melodies, big hooks, and pop accessibility of European chart music. Characterized by bright piano/organ stabs (often from the Korg M1), prominent diva-style vocals or chant-like hooks, punchy 909/808 drum programming, and uplifting chord progressions, euro house aimed squarely at radio and mainstream dancefloors. It often overlaps with early Eurodance, but tends to keep closer to straight house grooves and fewer rap verses. The style was driven largely by Italian, German, Belgian, and British producers and labels, delivering high-energy tracks that translated equally well to clubs, TV music shows, and pan-European charts.

Eurobeat is a high-tempo, hook-driven form of European dance music that emerged in Italy in the late 1980s and was developed primarily for the Japanese market in the 1990s. It is characterized by four-on-the-floor rhythms around 150–160 BPM, bright supersaw leads, dramatic chord progressions in minor keys, and anthemic, often English-language choruses. Unlike Eurodance, Eurobeat leans heavily on Italo-disco and Hi-NRG aesthetics, with dense layers of synths, punchy drum programming, and soaring toplines sung by a roster of Italian session vocalists under multiple aliases. The style became tightly linked to Japan through the long-running Super Eurobeat compilations, Para Para club culture, and pop-cultural placements (notably the Initial D franchise).

Folk is a song-centered acoustic tradition rooted in community storytelling, everyday life, and social history. It emphasizes clear melodies, simple harmonies, and lyrics that foreground narrative, protest, and personal testimony. As a modern recorded genre, folk coalesced in the early-to-mid 20th century in the United States out of older ballad, work song, and rural dance traditions. It typically features acoustic instruments (guitar, banjo, fiddle, mandolin, harmonica), strophic song forms, and participatory singing (choruses, call-and-response).

Hard rock is a loud, riff-driven style of rock music built around heavily amplified electric guitars, a powerful rhythm section, and assertive vocals. Songs typically center on memorable, blues-based guitar riffs, strong backbeats, and energetic, often shouted or belted choruses. The genre emphasizes power, groove, and visceral impact over intricate harmony or extended improvisation. Distortion, power chords, pentatonic melodies, and call‑and‑response between vocals and guitar are core traits, while lyrical themes often explore rebellion, lust, swagger, escape, and cathartic release.

Heavy metal is a loud, guitar-driven style of rock defined by heavily distorted riffs, thunderous drums, and powerful vocals. Its musical language emphasizes minor modes, modal (Aeolian, Phrygian) riffing, and energy over groove, often featuring virtuosic guitar solos and dramatic dynamic contrasts. Emerging from late-1960s blues rock and psychedelic experimentation, heavy metal codified a darker, heavier sound with bands like Black Sabbath, Deep Purple, and Led Zeppelin. The genre values weight, intensity, and grandeur—whether through plodding, doom-laden tempos or galloping, high-energy rhythms—paired with themes that range from personal struggle and social critique to fantasy, mythology, and the occult.

Hip hop is a cultural and musical movement that emerged from Black, Latino, and Caribbean communities, centering around rapping (MCing), DJing/turntablism, sampling-based production, and rhythmic speech over beats. It prioritizes groove, wordplay, and storytelling, often reflecting the social realities of urban life. Musically, hip hop is built on drum-centric rhythms (from breakbeats to 808 patterns), looped samples, and bass-forward mixes. Lyrically, it ranges from party anthems and braggadocio to political commentary and intricate poetic forms, with flow, cadence, and rhyme density as core expressive tools. Beyond music, hip hop encompasses a broader culture, historically intertwined with graffiti, b-boying/b-girling (breakdance), fashion, and street entrepreneurship, making it both an art form and a global social language.

Hip hop soul fuses the vocal traditions of soul and contemporary R&B with the production aesthetics and rhythms of hip hop. It typically features emotive, melismatic singing over boom‑bap or sample-driven beats, with frequent rap features and remix culture bridging R&B hooks and MC verses. Compared with new jack swing’s brighter, digitized swingbeat, hip hop soul adopts grittier drum textures, deeper bass, and loop-based arrangements drawn from crate-digging or programmed on samplers. Lyrically it centers on love, heartbreak, resilience, and urban life, often delivered with an assertive, streetwise attitude that mirrors hip hop’s aesthetics. The style reached mainstream prominence in the 1990s through artists like Mary J. Blige, Aaliyah, TLC, and Faith Evans, and set the template for much of late-1990s and 2000s R&B.

House is a dance music genre that emerged in Chicago in the early 1980s, defined by a steady four-on-the-floor kick drum, off-beat hi-hats, soulful or hypnotic vocals, and groove-centric basslines. Typical tempos range from 118–130 BPM, and tracks are structured in DJ-friendly 16–32 bar phrases designed for seamless mixing. Drawing on disco’s celebratory spirit, electro-funk’s drum-machine rigor, and Italo/Hi-NRG’s synth-led sheen, house prioritizes repetition, tension-and-release, and communal energy on the dancefloor. Its sound palette often includes 808/909 drums, sampled or replayed disco/funk elements, filtered loops, piano/organ stabs, and warm, jazzy chords. Over time, house diversified into many substyles—deep house, acid house, French house, tech house, progressive house, and more—yet it remains a global foundation of club culture, known for emphasizing groove, inclusivity, and euphoria.

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.

MPB (Música Popular Brasileira) is a broad Brazilian popular music movement that crystallized in the mid-1960s after bossa nova. It blends samba and other regional rhythms with jazz harmony, singer‑songwriter craft, and elements of contemporary pop and rock. The style is marked by sophisticated melodies, extended harmonies, inventive arrangements, and lyrically rich songs that often use poetry and metaphor. Many classic MPB works balance intimacy (voice and violão/nylon‑string guitar) with lush studio orchestration, drawing from samba‑canção, choro, baião, and frevo while engaging modern influences. Historically, MPB provided a platform for social commentary during Brazil’s military dictatorship, with artists employing allegory to navigate censorship. It remains a living tradition that continually renews itself through new generations (“nova MPB”).

Nueva trova is a Cuban singer‑songwriter movement that emerged in the late 1960s, blending the poetic intimacy of the island’s older trova tradition with socially conscious, often revolutionary, lyrics. It is typically guitar‑led and intimate, but can expand to small ensembles with subtle jazz‑inflected harmonies, echoing the filin (feeling) style and the romanticism of bolero while drawing rhythmic color from Cuban son and guajira. While aesthetically close to the broader Latin American nueva canción, nueva trova is distinctly Cuban in its idiom, metaphorical language, and engagement with post‑1959 cultural life.

Pop is a broad, hook-driven style of popular music designed for wide appeal. It emphasizes memorable melodies, concise song structures, polished vocals, and production intended for radio, charts, and mass media. While pop continually absorbs elements from other styles, its core remains singable choruses, accessible harmonies, and rhythmic clarity. Typical forms include verse–pre-chorus–chorus, frequent use of bridges and middle-eights, and ear-catching intros and outros. Pop is not defined by a single instrumentation. It flexibly incorporates acoustic and electric instruments, drum machines, synthesizers, and increasingly digital production techniques, always in service of the song and the hook.

Pop rap blends the rhythmic vocal delivery and beat-centric production of hip hop with the catchy hooks, polished structures, and radio-friendly sensibilities of pop music. It typically features melodic choruses (often sung), accessible themes, and mid-tempo grooves designed for mass appeal. Production prioritizes clean, bright sonics, simple harmonic progressions, and memorable top-line melodies, while verses keep to clear, punchy flows that are easy for broad audiences to follow. Because it sits between two commercial powerhouses—pop and hip hop—pop rap has frequently served as a gateway for mainstream listeners to explore rap, while giving hip hop artists a framework to cross over to pop charts.

R&B (Rhythm and Blues) is a vocal- and groove-centered popular music tradition that blends blues tonality, jazz harmony, and gospel-inflected singing with a steady backbeat. It emphasizes expressive lead vocals, call-and-response, lush harmonies, and danceable rhythms. From its 1940s roots in African American communities to its later evolutions, R&B has continually absorbed and reshaped surrounding sounds—from jump blues and swing in the early days to soul, funk, hip hop, and electronic production in the contemporary era. Today, R&B ranges from intimate, slow-burning ballads to club-ready tracks, all tied together by a focus on feel, melody, and vocal performance.

Reggae is a popular music genre from Jamaica characterized by a laid-back, syncopated groove, prominent bass lines, and steady offbeat “skank” guitar or keyboard chords. The rhythmic core often emphasizes the third beat in a bar (the “one drop”), creating a spacious, rolling feel that foregrounds bass and drums. Typical instrumentation includes drum kit, electric bass, rhythm and lead guitars, keyboards/organ (notably the Hammond and the percussive "bubble"), and often horn sections. Tempos generally sit around 70–80 BPM (or 140–160 BPM felt in half-time), allowing vocals to breathe and messages to be clearly delivered. Lyrically, reggae ranges from love songs and everyday storytelling to incisive social commentary, resistance, and spirituality, with Rastafarian culture and language (e.g., “I and I”) playing a central role in many classic recordings. Studio production techniques—spring reverbs, tape delays, and creative mixing—became signature elements, especially through dub versions that strip down and reimagine tracks.

Rock is a broad family of popular music centered on amplified instruments, a strong backbeat, and song forms that foreground riffs, choruses, and anthemic hooks. Emerging from mid‑20th‑century American styles like rhythm & blues, country, and gospel-inflected rock and roll, rock quickly expanded in scope—absorbing folk, blues, and psychedelic ideas—while shaping global youth culture. Core sonic markers include electric guitar (often overdriven), electric bass, drum kit emphasizing beats 2 and 4, and emotive lead vocals. Rock songs commonly use verse–chorus structures, blues-derived harmony, and memorable melodic motifs, ranging from intimate ballads to high‑energy, stadium‑sized performances.

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.

Samba is an Afro‑Brazilian musical and dance tradition that crystallized in Rio de Janeiro in the early 20th century, rooted in the rhythms, rituals, and communal celebrations of the Afro‑diasporic population. It is typically in 2/4 meter with characteristic syncopations, off‑beat accents, and call‑and‑response refrains. The groove is carried by a bateria (percussion ensemble) featuring surdo, pandeiro, tamborim, cuíca, agogô, reco‑reco, and repinique, while chordal instruments such as violão (6‑ and 7‑string guitars) and cavaquinho provide rich, swinging harmonies. Melodies often draw on Portuguese lyric traditions, African rhythmic phrasing, and the expressive poetics of everyday urban life—love, neighborhood pride, carnival, devotion, and saudade. Across the 20th century, samba diversified into many substyles (samba‑canção, samba‑enredo, partido‑alto, samba de roda, samba de gafieira), and later catalyzed entire currents like bossa nova, MPB, and samba‑rock, remaining Brazil’s most globally recognizable sound.

Trance is a form of electronic dance music characterized by steady four-on-the-floor beats, long build‑ups and breakdowns, and euphoric, melodic progressions designed to induce a hypnotic or “trance‑like” state. Typical tempos range from about 130 to 142 BPM, with arrangements often stretching 7–10 minutes to allow DJs room for tension, release, and seamless mixing. The sound palette emphasizes shimmering pads, arpeggiated synth motifs, supersaw leads, and wide, reverberant spaces. Harmonically, trance tends to favor minor keys, modal mixture, and extended suspense before cathartic drops. Production hallmarks include sidechain compression (“pumping”), off‑beat open hi‑hats, rolling basslines, and lush delay/reverb tails. While largely instrumental, a major branch—vocal trance—features lyrical toplines and pop‑leaning structures without losing its club‑centric dynamics.

World music is a broad, industry-coined umbrella for traditional, folk, and contemporary popular styles from around the globe that fall outside the Anglo-American pop mainstream. The label emerged in the 1980s as a retail and marketing category to group diverse regional musics for international distribution. Musically, it spans acoustic and electric instrumentation; modal, pentatonic, and microtonal pitch systems; and rhythms ranging from cyclical grooves and polyrhythms to asymmetrical meters. While the term can obscure local specificity, it also facilitated cross-cultural collaboration, festivals, and recordings that brought regional genres to wider audiences.
