Rapping, also referred to as MCing emceeing, is a vocal style in which the artist speaks lyrically, in the rhyme and verse, generally to an instrumental or synthesised 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 synthesisers, drum machines and live bands. Rappers may write, memorised or improvised their lyrics and perform their works as cappella or to a beat.
