As cultural and literary scholar Henry Louis Gates, Jr.  claims, "Repetition and revision are fundamental to black artistic forms, from painting and sculpture to music and language use."

Therefore, discuss one significant subject or theme that hip-hop artists Signify on in the African American literary tradition as they express their own notions of Blackness in lyrical rap music.
