Origins of rock and roll The phrase "rocking and rolling" originally described the movement of a ship on the ocean, but it was used by the early 20th century, both to describe a spiritual fervor and as a sexual analogy. Various gospel, blues and swing recordings used the phrase before it became used more frequently – but still intermittently – in the late 1930s and 1940s, principally on recordings and in reviews of what became known as "rhythm and blues" music aimed at black audiences. In 1951, Cleveland-based disc jockey Alan Freed began playing this music style while popularizing the term "rock and roll" to describe it.[1]
