in Jamaican ska era, 60's, a DJ would spin and cut the wax and a MC would sing or shout or dub poetry over it. That's the roots of hiphop which were brought to New York City by Kool DJ Herc, but hip-hop or rap was created in New York City
Hip hop or hip-hop is a sub-cultural movement that formed during the early 1970s by African-American and Puerto Rican youths residing in the South Bronx in New York City. It became popular outside of the African-American community in the late 1980s and by the 2000s became the most listened-to musical genre in the world. It is characterized by four distinct elements, all of which represent the different manifestations of the culture: rap music (oral), turntablism or DJing (aural), b-boying (physical) and graffiti art (visual). Even while it continues to develop globally in myriad styles, these four foundational elements provide coherence to hip hop culture. The term is often used in a restrictive fashion as synonymous only with the oral practice of rap music.
