What is "calypsonian"

n. A calypso musician.

A calypsonian, originally known as the chantwell, is a musician, from the anglophone Caribbean, who sings songs called calypso. Calypsos are musical renditions having their origins in the West African griot tradition. Originally called "Kaiso" in Trinidad, these songs, based on West African Yoruba, Ewe-Fon and Akan musical beats, were sung by slaves and later ex-slaves in Trinidad and Tobago during recreation time and about a host of topics – their land of origin, social relationships on the plantations and the lives of community members, including plantation managers, overseers and owners.
