Beat music, British beat, or Merseybeat is a British popular music genre that developed, particularly in and around Liverpool, in the late 1950s and early 1960s. The genre melded influences from American rock and roll, rhythm and blues, skiffle, traditional pop and music hall. It rose to mainstream popularity in the UK and Europe by 1963 before spreading to the North America in 1964 with the British Invasion. The beat style had a significant impact on popular music and youth culture, from 1960s movements such as garage rock, folk rock and psychedelic music to 1970s punk rock and 1990s Britpop.
