Rock-and-Roll (räk`n roll`) n. first so used (1951) by Alan Freed, Cleveland disc jockey, taken from the song "My Baby Rocks Me with a Steady Roll". The use of rock, roll, rock and roll, etc., with reference to sexual intercourse, is traditional in blues, a form of popular music that evolved in the 1950`s from rhythm and blues, characterized by the use of electric guitars, a strong rhythm with an accent on the offbeat, and youth-oriented lyrics.
Rock & roll (also known as rock `n` roll), is a defined genre of music that originated in the Southern United States in the 1950s, and quickly spread to the rest of the country and on to the world. It later evolved into the various sub-genres of what is now called simply `rock`. From the late 1950s to the mid 1990s rock was one of the most popular form of music in the western world. Rock and roll is most typically played with an electric guitar, an electric bass guitar, a drum kit, and sometimes a piano or keyboard. In the early rock and roll style of the early 1950s, the saxophone was often the lead instrument, replaced by guitar in the late 50`s.
Rock and roll emerged as a defined musical style in America in the 1950s, though elements of rock and roll can be heard in blues records as far back as the 1920s. Early rock and roll combined elements of blues, boogie woogie, and jazz with influences from traditional Appalachian folk music, gospel, and especially country and western. Going back even further, rock and roll can trace a foundational lineage to the old Five Points district of mid-19th century New York City, the scene of the first fusion of heavily rhythmic African shuffles and sand dances with melody-driven European genres, particularly the Irish jig. Rocking was a term first used by black gospel singers in the American South to mean something akin to spiritual rapture. By the 1940s, however, the term was used as a double entendre, ostensibly referring to dancing, but with the hidden subtextual meaning of sex; an example of this is Roy Brown`s "Good Rocking Tonight." This type of song was usually relegated to "race music" (the music industry code name for rhythm and blues) outlets and was rarely heard by mainstream white audiences.
