In the 1970s, rap began to emerge as a distinct genre of music. Early rap artists such as Grandmaster Flash and the Furious Five, Kurtis Blow, and LL Cool J helped to popularize the genre, and by the 1980s, rap had become a mainstream phenomenon.
Rap music is often characterized by its use of rhyming lyrics, spoken in a rhythmic, percussive style over a backing beat. Rap artists often use their lyrics to express their personal experiences, social and political issues, or to simply entertain their listeners.
Rap music has had a significant influence on popular culture, and has helped to shape the way we think about music, language, and art. It has also played an important role in giving a voice to African Americans and other marginalized communities.
