Hip hop or hip-hop is a subculture and art movement developed in South Bronx in New York City during the late 1970s.
 While people unfamiliar with hip hop culture often use the expression "hip hop" to refer exclusively to hip hop music (also called "rap"), Hip hop is characterized by nine distinct elements or expressive realms, of which hip hop music is only four elements (rapping, djaying, beatboxing and breaking).
 Afrika Bambaataa of the hip hop collective Zulu Nation outlined the pillars of hip hop culture, coining the terms: "rapping" (also called MCing or emceeing), a rhythmic vocal rhyming style (orality); DJing (and turntablism), which is making music with record players and DJ mixers (aural/sound and music creation); b-boying/b-girling/breakdancing (movement/dance); and graffiti art, which he called "aerosol writin'", although many say that the graffiti that hip hop adopted had been around years earlier, and had nothing to do with hip hop culture.
 (visual art).
 Other elements of hip hop subculture and arts movements beyond the main four are: hip hop culture and historical knowledge of the movement (intellectual/philosophical); beatboxing, a percussive vocal style; street entrepreneurship; hip hop language; and hip hop fashion and style, among others.
