Rock music


Rock music is a form of popular music with a prominent vocal melody accompanied by guitar, drums, and bass. Many styles of rock music also use keyboard instruments such as organ, piano, or synthesizers. Rock music usually has a strong back beat, and often revolves around guitar, either electric or acoustic.

Rock music has its roots in 1950s-era rock and roll and rockabilly. In the late 1960s, rock music was blended with folk music to create folk rock, and with jazz, to create jazz-rock fusion, and without a time signature to create Psychedelic rock. In the 1970s, rock incorporated influences from soul, funk, and latin music. Also in the 1970s, rock developed a number of subgenres, such as soft rock, blues rock, hard rock, progressive rock, heavy metal and punk rock. The most popular rock from the seventies evolved though out of a mixture of Psychedelic rock and progressive rock to create Art or Glamour Rock. Rock subgenres from the 1980s included glam metal, synth-rock and alternative rock. In the 1990s, rock subgenres included grunge-style rock, Britpop, Indie rock, piano rock, surf rock and nu metal.
