Hip hop music

Hip hop music is a style of popular music composed of a rhythmic, rhyming vocal style called rapping (also known as emceeing) over backing beats and scratching performed on a turntable by a DJ. When combined with breakdancing and graffiti art, these are the four components of hip hop, a cultural movement which began in New York City in the 1970s, predominantly among African Americans and Latinos. The term rap music is sometimes used synonymously with hip hop music, though it is also used to refer specifically to the practice of rapping.
