rap is the vocal part of it. you can do it to music or not. one can rap on a street corner with no accompaniment whatsoever, or in the shower, etc. hip hop is the wider genre of music, much of which has rapping in it, but not all of it. there are instrumental hip hop songs, and hip hop songs with only non-rap singing. kool keith, beastie boys and jurassic 5 come to mind for instrumental tracks, out of the stuff i've heard. that is, hip hop tracks with no rapping. DJs like z-trip also produce hip-hop backing tracks suitable for rapping over but wouldn't be called rap music by itself.
