Freestyle is a style of Hip Hop where an artist improvises an unwritten verse from the head, with or without instrumental beats, in which lyrics are recited with no particular subject or structure.[1][2][3][4][5] It is similar to other improvisational music, such as jazz,[6] where a lead instrumentalist acts as an improviser with a supporting band providing a beat. Freestyle originally was simply verse that is free of style, written rhymes that do not follow a specific subject matter, or predetermined cadence. The newer style with the improvisation grew popular starting in the early 1990s. It is now mainly associated with hip hop.
