Rock music roll, which originated in the United States during the late 1940s and early 1950s, and quickly spread to much of the rest of the world. Its immediate origins lay in a melding of various black musical genres of the time, including rhythm and blues and gospel music, with country and western. In 1951, Cleveland, Ohio disc jockey Alan Freed began playing rhythm and blues music (then termed "race music") for a multi-racial audience, and is credited with first using the phrase "rock and roll" to describe the music. Debate surrounds which record should be considered the first rock and roll
Origins of rock and roll to the phrase being taken as a double entendre, with the interpretation as religious or sexual. The following year, Western swing musician Buddy Jones recorded "Rockin' Rollin' Mama", which drew on the term's original meaning – "Waves on the ocean, waves in the sea/ But that gal of mine rolls just right for me/ Rockin' rollin' mama, I love the way you rock and roll". In August 1939, Irene Castle devised a new dance called "The Castle Rock and Roll", described as "an easy swing step", which she performed at the Dancing Masters of America convention at the Hotel Astor.
