Extempo

Extempo (also extempo calypso) is a lyrically improvised form of calypso and is most notably practiced in Grenada and Trinidad and Tobago. It consists of performers improvising in song or in rhythmic speech on a given theme before an audience, which take turns to perform. It is inherently competitive, and success is judged by the wit and the ingenuity of the performance.

It is similar in form to what has been defined as traditional African song: "a recitative or chants with a short chorus. The soloist gives the melody while a chorus sings a refrain. As the melody is given out, they turn to one another, each improvising in turn. Extempo tends to comprise topics from current events treated with mockery, ridicule and sarcasm, or with flattery or praise.”[This quote needs a citation]
