Alternative rock is a broad umbrella for guitar-based rock that emerged from the independent and college-radio scenes as a counterpoint to mainstream, commercial rock. It blends the energy and ethos of punk with the textural and songwriting experiments of post-punk, new wave, jangle pop, and noise rock, often foregrounding introspective or socially aware lyrics. Across its many strains—from the melodic minimalism of college rock to the loud-quiet-loud dynamics of grunge and the artful experimentation of Radiohead-era modernism—alternative rock prioritizes authenticity, sonic individuality, and a do-it-yourself approach. Its sound ranges from chiming, chorus-laden clean guitars to abrasive distortion and feedback, supported by straightforward rock rhythms or off-kilter grooves, and production that can be either raw and live-sounding or polished yet unconventional.

Bachata is a guitar-driven popular music and dance style that originated in the Dominican Republic. It blends the romantic lyricism and harmonic language of bolero with rhythmic accents and dance energy connected to Dominican merengue and Afro-Caribbean son traditions. The classic ensemble features a lead guitar (requinto), rhythm guitar, bass, bongos, and güira. Typical songs are in 4/4 time with syncopated bongo martillos and a steady güira pattern, while the guitars alternate arpeggios, bachata rasgueos, and melodic fills. Lyrically, bachata is renowned for amargue (bitterness)—poignant narratives of love, longing, heartbreak, and desire—though modern variants also embrace flirtation and celebration. Since the 1990s, "bachata romántica" and 2000s urban/pop bachata have expanded the sound with electric guitars, keyboards, R&B harmonies, and pop structures, taking the genre from a once-marginalized style to a global Latin pop mainstay.

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 rock blends the instrumentation and attitude of rock with Afro‑Latin and Caribbean rhythms, percussion, and song forms. Typical bands combine electric guitars, bass, and drum kit with congas, bongos, timbales, and hand percussion, creating a driving, danceable groove grounded in the clave. Vocals may be in Spanish, Portuguese, Spanglish, or English, and lyrics range from love songs and urban life to social and political commentary. Harmonically, Latin rock draws from blues/rock progressions but frequently incorporates modal colors (Dorian, Mixolydian) and montuno‑style vamps borrowed from salsa and Afro‑Cuban traditions. The result sits comfortably between club‑ready rhythm and arena‑sized rock 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.

Cumbia is a syncretic dance-music tradition from Colombia’s Caribbean coast that blends African rhythmic heritage, Indigenous (especially gaita flute) melodic practice, and Spanish colonial instrumentation and forms. Traditionally performed in a moderate 2/4 (often felt in 4/4 today), it features interlocking hand-drum parts (tambora, alegre, llamador), guacharaca or maracas for steady texture, and long cane flutes (gaita hembra and gaita macho) carrying call-and-response melodies. As it spread in the 20th century, orchestras and dance bands added accordion, horns, piano, bass, and later electric guitar and synthesizers, creating urban and pan–Latin American variants. Harmonically simple and rhythm-forward, cumbia places groove, ostinati, and vocal refrains at the center, making it both ceremonial in origin and enduringly popular on social dance floors across the Americas.

Cumbia argentina is the Argentine adaptation of Colombian cumbia that took root in the 1960s and evolved into a family of local styles. It blends the syncopated cumbia groove with regional tastes, instrumentation, and social realities in Argentina, producing variants such as the accordion‑led cumbia santafesina, the synth‑driven and street‑narrative cumbia villera, and radio‑friendly cumbia pop. Typical arrangements feature the cumbia beat on drum kit or programmed drums, congas and güiro driving the off‑beat swing, bass guitar outlining a steady tumbao, and lead voices supported by call‑and‑response coros. Depending on the substyle, melodies are carried by accordion, electric guitar, or bright keyboards. Lyrics range from romantic stories and dancefloor invitations to depictions of barrio life, celebration, and struggle. The result is a dance music that is both festive and deeply tied to Argentine urban and provincial identities.

Electrotango (often called tango electrónico) fuses the melodic drama, syncopated phrasing, and emblematic bandoneon timbre of Argentine tango with contemporary electronic production. Producers blend sampled or newly recorded tango ensembles (bandoneon, violin, piano, double bass, guitar) with downtempo, trip-hop, and house beats, warm analog-style bass lines, and ambient textures. Tempos commonly range from 90–120 BPM for lounge/downtempo contexts and up to 120–128 BPM for club-focused remixes. Core rhythmic cells include the tango’s 3–3–2 syncopation, habanera-derived grooves, and marcato patterns, while harmonies favor minor keys, chromatic lines, and bittersweet cadences that accentuate tango’s nostalgic and urban character.

Experimental rock is a broad, exploratory branch of rock music that prioritizes innovation over convention. It stretches rock’s core instrumentation and song forms through unusual timbres, extended techniques, nonstandard tunings, chance procedures, and studio-as-instrument production. Drawing on avant-garde composition, free jazz, minimalism, and electronic/tape music, experimental rock often rejects verse–chorus structures in favor of drones, suites, collage, and improvisation. It embraces dissonance and noise as expressive tools, employs odd or fluid meters, and incorporates non-rock instruments, found sounds, and unconventional recording methods. The result is a lineage of music that treats rock not as a fixed style but as a laboratory for new sound worlds.

Folk rock is a fusion genre that blends the narrative lyricism, modal melodies, and acoustic timbres of traditional folk with the backbeat, amplification, and song structures of rock. It typically pairs acoustic or traditional instruments (acoustic guitar, mandolin, fiddle) with a rock rhythm section (electric guitar, bass, drums), often featuring chiming 12‑string guitar textures, close vocal harmonies, and socially conscious or storytelling lyrics. The result ranges from intimate, reflective ballads with a steady backbeat to more anthemic, roots‑driven rock. Emerging in the mid‑1960s through artists such as Bob Dylan and The Byrds, folk rock became a gateway for traditional and roots materials to enter mainstream popular music, and it seeded later movements from country rock and Americana to jangle pop and modern indie folk.

Gothic rock is a dark, atmospheric branch of post-punk that emphasizes brooding moods, melodic basslines, baritone or icy vocal deliveries, and guitar textures drenched in chorus, delay, and reverb. Its lyrics often explore themes of romanticism, existential dread, night, mysticism, and decay, drawing on Gothic literature and cinema as much as rock tradition. Sonically, it blends the stark rhythms and minimalism of post-punk with the theatricality of glam and the textural experimentation of art and psychedelic rock. Drum machines or tightly metronomic drumming underpin prominent, melodic bass figures, while guitars shimmer or scrape with chorus/flanger effects. The result is danceable yet somber music that feels both dramatic and introspective.

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.

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 rock blends the hook-focused immediacy of pop with the instrumentation and drive of rock. It prioritizes catchy melodies, concise song structures, and polished production while retaining guitars, bass, and drums as core elements. Typical pop rock tracks use verse–pre-chorus–chorus forms, strong vocal harmonies, and memorable riffs. The sound ranges from jangly and bright to mildly overdriven and arena-ready, aiming for radio-friendly appeal without abandoning rock’s rhythmic punch.

Progressive is an umbrella aesthetic that prioritizes musical development—extended forms, evolving arrangements, sophisticated harmony, and conceptual ambition—over verse–chorus simplicity. Emerging from late-1960s rock and psychedelia, the progressive approach soon permeated multiple styles (rock, electronic, metal, pop, dance music), where "progressive" signals pieces that unfold gradually, introduce new motifs across long arcs, and use timbral and harmonic exploration as core drama. Across its variants, listeners can expect longer tracks, thematic continuity (sometimes across whole albums), expanded instrument palettes (from orchestral colors to synthesizers), odd meters, key changes, and a narrative sense of journey.

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.
