Rap is original poetry recited in rhythm and rhyme over prerecorded instrumental tracks. Rap music (also referred to as rap or hip-hop music) evolved in conjunction with the cultural movement called hip-hop. Rap emerged as a minimalist street sound against the backdrop of the heavily orchestrated and formulaic music coming from the local house parties to dance clubs in the early 1970s. Its earliest performers comprise MCs (derived from master of ceremonies but referring to the actual rapper) and DJs (who use and often manipulate pre-recorded tracks as a backdrop to the rap), break dancers and graffiti writers.
