Hip hop music is a style of popular music. It is usually composed of two elements: rapping (also known as emceeing) and DJing. 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 by 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, which is one component of hip hop
