Rap
Rapping, also referred to as MCing or emceeing, is a vocal style in which the artist speaks lyrically, in rhyme and verse, generally to an instrumental or synthesized beat. Beats, almost always in 4/4 time signature, can be created by looping portions of other songs, usually by a DJ, or sampled from portions of other songs by a producer. Modern beats incorporate synthesizers, drum machines, and live bands. Rappers may write, memorize, or improvise their lyrics and perform their works a cappella or to a beat.
