Rap and hip hop are two genres of music that emerged in the late 1970s and early 1980s in the United States, especially among African American and Latino communities. Rap is a form of vocal delivery that incorporates rhyme, rhythm, and wordplay, often accompanied by a beat or musical accompaniment. Hip hop is a broader cultural movement that encompasses rap, as well as other elements such as DJing, breakdancing, graffiti, and fashion. Rap and hip hop have influenced many aspects of popular culture, such as language, art, politics, and social issues. Rap and hip hop artists use their music to express their views, experiences, and identities, as well as to challenge stereotypes, injustices, and oppression.
