Hip Hop is a popular culture movement that originated in African American and Latino communities in New York City during the 1970s. It encompasses four main elements: rapping (MCing), DJing, breakdancing, and graffiti art. Hip hop music often contains rhythmic and rhyming speech, and it frequently discusses themes such as poverty, crime, and social injustice. The culture has since spread worldwide and evolved into various subgenres, including gangsta rap, conscious hip hop, and alternative hip hop.
