During an annual Mossi people ritual which takes place in Oueguedo in Burkina Faso, stories of the ancestors are told in drum language. “Who is your grandfather?” cries the master of ceremony to the chief of the tribe and to all those present, after the ritual sacrifice of a beast. “Who is your grandfather?” In response, the ‘benda’ gives the names of ancestors and tells the anecdotes that relate to them, in rhythm. This is how the oral history is transmitted from generation to generation.
