Rock and roll (often written as rock & roll or rock 'n' roll) is a genre of popular music that originated and evolved in the United States during the late 1940s and early 1950s, primarily from a combination of the blues, country music, jazz and gospel music. Though elements of rock and roll can be heard in country records of the 1930s, and in blues records from the 1920s, rock and roll did not acquire its name until the 1950s. An early form of rock and roll was rockabilly, which combined country and jazz with influences from traditional Appalachian folk music and gospel.
The term "rock and roll" now has at least two different meanings, both in common usage. The American Heritage Dictionary and the Merriam-Webster Dictionary both define rock and roll as synonymous with rock music. Allwords.com, however, refers specifically to the music of the 1950s. For the purpose of differentiation, this article uses the latter definition, while the broader musical genre is discussed in the rock music article.
