Calypso originated in West African griots and developed alongside other traditional Caribbean songs to incorporate elements of digging songs changed by people at work; belair and calinda songs when they play; shango and shouter baptist revival songs when they worship; and insurrectionary songs such as were sung by slaves in revolt
