Beat music, British beat, or Merseybeat (after bands from Liverpool and nearby areas beside the River Mersey) is a pop and rock music genre that developed in the United Kingdom in the early 1960s. Beat music is a fusion of rock and roll (mainly Chuck Berry guitar style and the midtempo beat of artists like Buddy Holly), doo-wop, skiffle and R&B. The genre provided many of the bands responsible for the British Invasion of the American pop charts starting in 1964, and provided the model for many important developments in pop and rock music, including the format of the rock group around lead, rhythm and bass guitars with drums.
The exact origins of the terms 'beat music' and 'Merseybeat' are uncertain. Beat music seems to have had little to do with the Beat Generation literary movement of the 1950s, and more to do with driving rhythms, which the bands had adopted from their rock and roll, rhythm and blues and soul music influences. As the initial wave of rock and roll declined in the later 1950s "big beat" music, later shortened to "beat", became a live dance alternative to the balladeers like Tommy Steele, Marty Wilde and Cliff Richard who were dominating the charts.
