The Yorouba king of drummers is called Ayan. The drum is the only way for the living to communicate with the Orishas and invite them to join them. The drummer seduces the ancestors and Orishas with the sound of the drum, asking them to participate. During this celebration, the Elegun or dancer is possessed by the Orisha. Omo Ayan are the children of Ayan and the only ones capable of bringing the “revenants” (undead) back to life. They play a key role in all Yoruba rituals and can enter sacred places forbidden to others, as their musical service is essential in worship.
