Hip hop music, also called hip-hop or rap music, is a music genre developed in the United States by inner-city African Americans in the late 1970s which consists of a stylized rhythmic music that commonly accompanies rapping, a rhythmic and rhyming speech that is chanted. It developed as part of Hip Hop culture, a subculture defined by four key stylistic elements: MCing/rapping, DJing/scratching with turntables, break dancing, and graffiti writing. Other elements include sampling beats or bass lines from records (or synthesized beats and sounds), and rhythmic beatboxing. While often used to refer solely to rapping, "hip hop" more properly denotes the practice of the entire subculture. The term rapping is not a required component of hip hop music; the genre may also incorporate other elements of hip hop culture, including DJing, turntablism, scratching, beatboxing, and instrumental tracks.
Etymology: "Hip-hop" has been in use since the 17th century to mean a succession of hops. In George Villiers' 1671 play The Rehearsal, Prince Volscius exits a scene awkwardly with one boot on and the other off. The director of the scene exclaims, "to go off hip hop, hip hop, upon this occasion, is a thousand times better than any conclusion in the world". A common variation on "hip hop" is "hippity hop", which was in wide usage by the 19th century. It appears in works like a poem from 1882 where four children sing, "Hippity hop to the candy Shop!" It was a common refrain in skipping games.
Many dance steps include a hop. By the 18th century, "hop" began to be used interchangeably with "dance" as both a noun and a verb.
