Rapping is a musical form of vocal delivery often associated with Hip-hop music & culture but according to certain sources, its origin might come from the West African griot tradition.
Three elements compose this musical form: the lyrics, the flow (rythme, rhyme) and the tone (delivery).
Rap is usually performed in time to an instrumental song but can also be performed a cappella.
Note: some people say that Rap stands for « Rhyme And Poetry » but many don’t agree with this definition.
