Rap music is a genre of popular music that originated in the African American community during the 1970s. It features rhythmic speech, often called "rapping," over a beat, which can be created using instruments or digital production. The lyrics often address social issues, personal experiences, and cultural themes, making it a powerful form of expression. The genre has evolved over the years, incorporating various styles and influences, including hip-hop, R&B, and jazz. Notable artists like Tupac Shakur and Notorious B.I.G. have significantly shaped its history, while contemporary artists continue to push the boundaries of rap music today.
