From Wikipedia: "Hip hop music is a genre of music typically consisting of a rhythmic style of speaking called rap over backing beats performed on a turntable by a DJ. Hip hop music is part of hip hop culture, which began in New York City in the 1970s, predominantly among African Americans and Latinos (the other two elements are breakdancing and graffiti art). The term rap is sometimes used synonymously with hip hop music, though it originally referred only to rapping itself."
