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 British and 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 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.

Rock and roll is a genre of popular music that evolved in the United States during the late 1940s and early 1950s. It originated from African American music such as jazz, rhythm and blues, boogie-woogie, electric blues, gospel, jump blues, as well as country music. While rock and roll's formative elements can be heard in blues records from the 1920s and in country records of the 1930s, the genre did not acquire its name until 1954.
