Children AfroRock Rock music played by African musicians, with Western instruments and harmonies, though sometimes with more distinctly African percussion instruments.
  AltMetal Characterized by most notably heavy riffs but usually with a pronounced experimental edge, including unconventional lyrics, more syncopation than typical metal, unusual technique, a resistance to conventional approaches to heavy music and an incorporation of a wide range of influences outside of the metal music scene.
  AlternativeRock Wide-ranging subgenre of rock music, originally underground, or (since the 90s, especially) mainstream but with roots in and major influence from prior underground music, such as punk.
  ArtRock Art Rock and Progressive Rock are quite similar. Art Rock, though, is more likely to have experimental or avant-garde influences, placing novel sonic texture above prog-rock's symphonic ambitions. Both Art Rock and Progressive rock stem from a mostly British attempt to elevate rock music to new levels of artistic credibility.
  BlackMetal Black Metal often employs fast tempos, shrieked vocals, highly distorted guitars played with tremolo picking, double-kick drumming, and unconventional song structure. When composing music, guitarists often use scales, intervals and chord progressions that produce the most dissonant, fearful and ominous sounds. Additionally, guitar solos and low guitar tunings are a rarity in black metal.
  BoogieRock Extending from the popular Blues Rock sounds of the late 1960s, Boogie Rock placed a greater emphasis on a repetitive groove instead of improvisation.
  BritPop Britpop is an amalgam of various group from English Pop history: The Beatles, The Kinks, David Bowie, The Smiths and XTC (among a plethora of others) created music which would influence a generation of British performers. Britpop focuses on British culture and the British experience with little regard for how it is perceived outside of British Society. Although it may have been moderately popular in foreign underground music scenes, the music is/was highly commercialized in the UK. Britpop typically has a bright sound, as the genre was formed as a response to the darker lyrical trends of popular music at the time.
  BritRock Brit Rock refers not to the entire pantheon of British Rock music, but instead a spate of British bands from the late 1980s- early 90s who were influenced by 1960s British Rock, New Wave and Punk.
  BritishInvasion Influenced by American Rock n Roll and Blues, a wave of British bands found popularity in the U.S. in the mid-1960s-- thanks in no small part to the Beatles. Their sound reflected a range of styles-- from bluesy hard rock to sweet pop/rock. A second wave in the late 60s found influence in both American musicians and their British precedents.
  ClassicRock The timeless rock format of the 1960s and 1970s. Hints of glam and psychedelia with the raw energy and palatability of 1960s Pop Rock.
  DarkWave Although Darkwave can be traced back to the beginnings of Post Punk and Synth Pop, the term was first used in the early 1980s to describe bands of these styles with a noticeably dark sound and lyrics. Darkwave is essentially Post Punk with a gothic sound and lyrics focusing on self-deprecation, angst and drug use.
  DeathMetal Death metal is an extreme subgenre of heavy metal. It typically employs fast tempos, heavily distorted guitars, deep demonic growling vocals, blast beat drumming, and complex song structures with multiple tempo changes.
  DoomMetal Doom metal is a form of heavy metal music that typically employs very slow tempos, low-tuned guitars and a much 'thicker' or 'heavier' sound than other metal genres. Both the music and the lyrics intend to evoke a sense of despair, dread, and impending doom.
  EarlyRock Mainstream rock styles prevalent before the 90s.
  ElectroGoth Combination of goth rock/dark wave and electronic music.
  EmoRock Emo rock is a style of rock music characterized by melodic musicianship and expressive, often confessional lyrics. It originated in the mid-1980s hardcore punk movement of Washington, DC, where it was known as 'emotional hardcore' or 'emocore' and pioneered by bands such as Rites of Spring and Embrace.
  ExperimentalRock Characterized by atypical sounds, arrangements, performance techniques, or production techniques.
  FunkMetal Combines hard-driving heavy metal guitar riffs, the pounding bass rhythms characteristic of funk, and sometimes hip hop-style rhymes into an alternative rock approach to songwriting.
  GarageRock Far more gritty and less melodic than its Pop Punk counterparts, Garage bands fostered an attitude that was frequently angry, cynical, darkly humorous and violent-- though its early practitioners were more playful. Garage garnered its name thanks to its amateur inclinations both in its live performance and production values. However, it defied geography and significantly influenced mainstream acts of the 1960s and 70s.
  GlamRock A sub-genre whose aesthetic is based as much on fashion as music, Glam Rock's flamboyant hedonism catered to a style that dabbled at once in hard rock and eccentric balladeering.
  GothicMetal It combines the aggression of heavy metal with the dark melancholy of gothic rock. The music of gothic metal is diverse with bands known to adopt the gothic approach to different styles of heavy metal music. Lyrics are generally melodramatic and mournful with inspiration from gothic fiction as well as personal experiences.
  GothicRock Also referred to as goth rock or simply goth, Gothic Rock is a musical subgenre of alternative rock. Gothic rock bands grew from the strong ties they had to the English punk rock and emerging post-punk scenes. The genre itself was defined as a separate movement from punk rock during the early 1980s largely due to the significant stylistic divergences of the movement; gothic rock, as opposed to punk, combines dark, often keyboard-heavy music with introspective and depressing lyrics.
  Grindcore Grindcore is characterized by heavily distorted, down-tuned guitars, high speed tempo, blast beats, songs often lasting no more than two minutes (some are seconds long), and vocals which consist of growls and high-pitched screams. Lyrical themes range from social and political issues to gore and black humor.
  Grunge Has its roots in Punk and Heavy Metal with heavily distorted guitars and lyrical themes of existential angst. Grunge was a reaction to the polished production, overwrought showmanship and fashion of mainstream music in the 1980s. However, in the 1990s Grunge dominated mainstream rock music due to the success of bands like Nirvana and Pearl Jam.
  HairMetal Also known as Glam Metal, Hair Metal is a subgenre of heavy metal, which features pop-influenced hooks and guitar riffs, and borrows from the fashion of 1970s glam rock.
  HardRock The major influence on hard rock is blues music. Considerably harder than conventional rock music. Hard rock is loud, aggressive guitar rock, but it isn't as heavy as heavy metal, and it's only very rarely influenced by punk (though it helped inspire punk). Hard rock generally prizes big, stadium-ready guitar riffs, anthemic choruses, and stomping, swaggering backbeats.
  HardcorePunk Hardcore punk (or hardcore) is an underground music genre that originated in the late 1970s, following the mainstream success of punk rock. Hardcore is generally faster, thicker, and heavier than earlier punk rock, while its vocalists usually scream, chant and use spoken word poetry. Hardcore was heavily involved with the rise of the independent record labels in the 1980s and with the DIY ethics in underground music scenes. It has influenced a number of music genres which have experienced mainstream success, such as alternative rock, metalcore, grunge, thrash metal, emo, and post-hardcore.
  HeartlandRock Influenced by 60s and 70s Garage Rock, Americana, and Roots rock, Heartland rock is a timeless genre that has mass appeal, catchy hooks, and anthemic production. This sub-genre is epitomized by Bruce Springsteen, Tom Petty, and Bob Seger.
  IndieRock Indie is short for 'independent,' leading one to assume that Indie Rock is concurrent with the Punk DIY aesthetic. Since Indie Rock is free of the mainstream, it allows bands to experiment and incorporate aspects of underground culture. Since the late 1990s, Indie Rock has grown in popularity with bands signing to corporate record labels and music publishers, thus Indie Rock has become more of a prescription for song composition than a protest against commercialism.
  Industrial Abrasive and aggressive fusion of rock and electronic music, industrial was initially a blend of avant-garde electronics experiments (tape music, musique concrète, white noise, synthesizers, sequencers, etc.) and punk provocation. It's early forms included mail art, performance art, installation pieces and other art forms.
  IndustrialMetal While pure 'industrial' takes its primary cues from experimental music and electronic dance, Industrial Metal makes the distorted noise of electric guitars a crucial part of the music. Ministry was the first band to popularize industrial metal in the late '80s, basing their signature grind on countless repetitions of jackhammer guitar riffs, as well as electronics, samples, and distorted vocals; however, it was Nine Inch Nails that really brought the sound to the mainstream during the early '90s, thanks to Trent Reznor's flair for melodic songwriting and multi-layered production.
  JovemGuarda Music from a Brazilian Television Program with performing musicians playing music influenced by early American rock and British Invasion bands.
  Krautrock Kraut Rock refers to the legions of German bands of the early '70s that expanded the sonic possibilities of art and progressive rock. Working with early synthesizers and splicing together seemingly unconnected reels of tape, bands like Faust, Can, and Neu created a droning, pulsating sound that owed more to the avant garde than to rock & roll.
  MathRock Has complex, frequently changing meters, contrapuntal guitar lines, and dissonant harmonies. Math rock draws influence from progressive rock and 20th century composers.
  Merseybeat Beat music constituted one of the first forms of British Pop not directly inspired by American musicians. Its most famous proponents are the Beatles, whose melodic sensibility and complex songwriting style harkened to more traditional forms of European folk music.
  Metal Characterized by a thick, massive sound with highly amplified distortion, extended guitar solos, and emphatic beats. The genre was pioneered by the bands Led Zeppelin, Black Sabbath, and Deep Purple. Metal music has since split into many sub genres.
  Metalcore Metalcore combines extreme metal with hardcore punk. The most defining characteristic of metalcore is the presence of breakdowns where the music goes into a half-time heavily syncopated groove. These breakdowns are generally the climax of intensity for the song. Blastbeats, and hardcore style double time riffs are also common.
  NoWave An avant-garde music scene that existed in the late 1970s and early 80s in New York City. Most No Wave groups prominently featured dissonance, atonality, and noise in their music, and they generally foregrounded musical texture over melody. No Wave groups, unlike other reactive scenes of the 70s, such as punk, generally rejected common rock tropes. The name 'No Wave' is a tongue-in-cheek reference to the then mainstream genre of New Wave. No Wave music varied widely in sound, and groups took influence from genres such as funk, free jazz, blues, and punk rock. No Wave represented a nihilistic philosophy inspired by the urban decay of 1970s New York. Brian Eno's compilation album No New York is a good introduction to the scene. In the 80s, the No Wave scene gravitated toward making more danceable music, and started to work in elements of hip hop, disco, dub reggae, and world music.
  NoiseRock Noise-Rock is an outgrowth of punk rock, specifically the sort of punk that expressed youthful angst and exuberance through the glorious racket of amateurishly played electric guitars. Most noise-rock bands concentrate on the ear-shattering sounds that can be produced by distorted electric guitars, some also use electronic instrumentation, whether as percussion or to add to an overall cacophony of sound.
  NuMetal Nu metal is a blend of grunge, alternative metal, and funk metal. Vocals have a range extending from melodic singing, rapping, and guttural screaming, to death growls and shouting. Bass parts are often reminiscent of hip hop or funk grooves, and in some songs, slap bass technique is used to give the music a funk groove.
  Oi Began in the UK as an attempt to keep Punk music rooted in working-class/street culture. It was a simpler, harder, and faster version of Punk - aligning itself with drinking songs and football chants. Unfortunately, (due to the band 'Skrewdriver') the genre became closely associated with Neo-Nazism.
  PopPunk Pop Punk is an amalgam of Punk and Pop, taking cues from mainstream pop music while playing in a punk style: fast distorted riffs, simple composition and melodies. Lyrics are usually wry, cocky and/or apathetic.
  PostGrunge Began to surface almost immediately after the commercial success of the Grunge movement. Post Grunge essentially used the Grunge aesthetic as a prescription for song composition-- imitating the Grunge sound, while incorporating mainstream production techniques. The result is a movement created specifically for the spotlight of the 1990s.
  PostHardcore A product of the early hardcore punk movement, Post-Hardcore conveys a more expressive and complex means of communicating aggravation and angst. Post-Hardcore utilizes the harsh, guitar-heavy timbres of Hardcore Punk, but expands beyond the fast tempos and three-chord composition.
  PostPunk Post Punk took the independent, D.I.Y. attitude of Punk and incorporated musical experimentation. This resulted in a more complicated derivative of Punk, with particular attention paid to lyrics and composition. Post Punk paved the way for what would become known as Alternative Rock/Pop music.
  PostRock Post-rock was the dominant form of experimental rock during the '90s. Post-rock was hypnotic and often droning (especially the guitar- oriented bands), and the brighter-sounding groups were still cool and cerebral -- overall, the antithesis of rock's visceral power.
  PowerPop Amalgam of pop and rock-- incorporates the energy of 1960s British rock groups with the Beatles-esque melodies and harmonies. Power Pop typically features crisp catchy guitar riffs, vibrant synths, tight vocal harmonies and a strong rhythm section. Production-wise, songs are typically polished and processed.
  ProgressiveMetal Progressive metal is a fusion genre; a mixture of progressive rock and heavy metal. Progressive metal blends the powerful, guitar-driven sound of metal with the complex compositional structures, odd time signatures, and intricate instrumental playing of progressive rock. Some progressive metal bands are also influenced by jazz fusion and classical music. Like progressive rock songs, progressive metal songs are usually much longer than standard metal songs, and they are often thematically linked in concept albums.
  ProgressiveRock Art Rock and Progressive Rock (Prog Rock) are quite similar. Prog Rock, though, tends to be more traditionally melodic (even when multi-sectioned compositions replace normal song structures), and more oriented toward classically trained instrumental technique. Both Art Rock and Prog Rock stem from a mostly British attempt to elevate rock music to new levels of artistic credibility.
  ProtoPunk Proto-Punk refers to a number of bands which were essential precursors to the Punk movement. Since the term refers to a large group of bands, the characteristics of the subgenre vary from band to band. For the most part, these bands were precursors to Punk because they represented the Punk aesthetic before there technically was a Punk aesthetic. These characteristics include primitive production, amateur sounding composition, DIY aesthetic, etc.
  PsychedelicRock Influenced by the psychedelic culture of the 1960s, Psychedelic Rock bands sought to expand the possibilities of Rock music by incorporating Eastern musical traditions, unusual effects for instruments and free-form song structures. Psychedelic Rock tends toward a dreamy impressionism in its aesthetic, though many of its practitioners were also attached to a traditional, hard-driving Rock sound.
  Psychobilly Psychobilly combined the Rockabilly revival of the late 70s/early 80s with a distinctly Punk aesthetic and attitude; fast rhythms and loud guitars are accompanied by a countrified swing. Psychobilly maintains a lyrical style that usually plays with cultural taboos, exploring topics like violence and sexuality.
  Punk Born in the 1970s out of 1960s garage music. Focused on the rejection of mainstream music and culture. Punk rock featured short fast-paced songs with simple instrumentation and harsh guitar and vocal tone. Some notable artists include Ramones, The Clash, and Sex Pistols.
  RiotGrrrl Riot Grrrl is a feminist punk movement closely associated with the LGBT movement, Queer Theory, and Straight Edge movements. Because of it's association with political activism, it has developed into a subculture. The music is comprised of typically loud and distorted instrumentation with a primary focus on political and social issue themed lyrics.
  RockNRoll Rock n Roll constitutes an early incarnation of Rock music, a genre of popular music characterized by small groups, boogie woogie blues rhythms, and often sexual lyrics. Rock n Roll had a massive social impact, influencing dance, fashion, language and other art forms, and would generate innumerable new genres over the ensuing decades.
  Rockabilly An amalgam of early Rock n Roll, Blues and Country music, Rockabilly's frenzied and visceral beat was usually performed with spare instrumentation that touched on traditional country/folk arrangements.
  SambaRock A Brazilian genre that fuses samba and rock elements.
  Screamo Screamo takes cues from Hardcore and Emo music, combining the two. The lyrics are typically overwrought and melodramatic, referring to relationships, self-deprecation and violence. The music is distorted and loud, embodying the existential angst inherent to the lyrics.
  Shoegaze Named after the stoic, hunched performances of its early progenitors, Shoegaze describes a style of Pop that is at once introspective, dense, melodic and noisy. Heavily effected guitars are often layered to create an all-encompassing and dreamlike atmosphere
  SoftRock Smoother sounding than hard rock, with melodic songs and lush production.
  SouthAmericanRock Blends influences from American Rock and South American Latin styles.
  SouthernRock Fusing 60s Blues Rock and Country, Southern Rock places an emphasis on electric guitar-led jams and Country-influenced melodies.
  SpaceRock Space rock refers to a new generation of alternative/indie bands that draw from psychedelic rock, ambient music, and -- more often than not -- experimental and avant-garde influences. Space rock is nearly always slow, hypnotic, and otherworldly; it typically favors lengthy, mind- bending sonic explorations over conventional song structures, and vocals sometimes play second fiddle to the shimmering instrumental textures.
  SpeedMetal Described as aggressive and 'extremely fast, abrasive, and technically demanding music. Also speed metal eventually toned down its intense tempos and evolved into thrash metal. Two of the most influential bands to the genre were English groups Motörhead and Judas Priest
  StonerRock Stoner rock and stoner metal are interchangeable terms describing sub-genres of rock and metal music. It combines elements of psychedelic rock, blues-rock and doom metal. Stoner rock is typically slow-to-mid tempo and features low-tuned guitars, a bass-heavy sound, melodic vocals, and 'retro' production.
  Surf Came out of the surfing culture of the early 1960s. Initially it was instrumental music featuring a lead saxophone or electric guitar heavily affected by reverb (to emulate the sound of the ocean). Vocal Surf Pop followed with notable acts such as The Beach Boys and Jan & Dean. There are a variety of guitar playing techniques that are associated with surf including bending notes downward with the whammy bar and tremolo picking. It was also one of the first Pop music styles to incorporate the use of electric bass. Through use of these techniques, the reverb, and later, beach-themed lyrics, performers sought to capture the essence of surfing in musical form. Named after the sport with which it became so closely associated, Surf rock is typified by reverb-effected electric guitar, three-chord song structures, rolling drum fills, and vocal harmonies.
  SwampRock Started in south Louisiana and combines New Orleans R&B, country, and traditional French Louisiana Musical Influences.
  ThirdWaveSka Combines elements of ska with punk, rock, and pop. e.g. The Mighty Mighty Bosstones and Reel Big Fish.
  ThrashMetal Thrash metal (sometimes referred to simply as thrash), is an extreme subgenre of heavy metal that is characterized by its fast tempo and aggression. Thrash metal songs typically use fast, percussive and low-register guitar riffs, overlaid with shredding-style lead work.[1] Thrash metal lyrics often deal with social issues using direct and denunciatory language, an approach which partially overlaps with the hardcore genre.
  Tropicalia The 1968 album Tropicália: ou Panis et Circencis is regarded as the musical manifesto of the Tropicália movement. Although it was a collaborative project, the main creative forces behind the album were Caetano Veloso and Gilberto Gil. The album experimented with unusual time signatures and unorthodox song structures, and also mixed tradition with innovation.
  TwoTone British music that fuses traditional ska with musical elements of punk rock and new wave music. It developed in the late 1980s.
  Underground Underground rock fabricated from bands and artists unwilling to be influenced by mainstream music and culture. Underground rock is described by the aesthetic of complete disconnect.
