Hip hop music is a genre of popular music developed in the United States by inner-city African Americans and Latino Americans in the Bronx borough of New York City in the 1970s. It consists of a stylized rhythmic music that commonly accompanies rapping, a rhythmic and rhyming speech that is chanted. While often used to refer solely to rapping, hip hop more properly denotes the practice of the entire subculture. The genre may also incorporate other elements of hip hop culture, including DJing, turntablism, scratching, beatboxing, and instrumental tracks.
