Hip-hop or hip hop is a popular music genre that emerged in the early 1970s from the African-American community of New York City. The style is characterized by its synthesis of a wide range of musical techniques. Hip-hop includes rapping often enough that the terms can be used synonymously. However, "hip-hop" more properly denotes an entire subculture. Other key markers of the genre are the disc jockey, turntablism, scratching, beatboxing, and instrumental tracks. Cultural interchange has always been central to the hip-hop genre. It simultaneously borrows from its social environment while commenting on it. From Wikipedia
