Rapping, also known as Emceeing, MCing, Rhyme spitting, Spitting, or just Rhyming, is the rhythmic delivery of rhymes, one of the central elements of hip hop music and culture. Although the word rap has sometimes been claimed to be a backronym of the phrase "Rhythmic American Poetry", "Rhythm and Poetry", "Rhythmically Applied Poetry", or "Rhythmically Associated Poetry", use of the word to describe quick and slangy speech or repartee long predates the musical form.One early example includes the spoken word group The Last Poets. Rapping can be delivered over a beat or without accompaniment.
