The "Nyonyose" (the ancient farmers and spiritual segment of Mossi society) use masks in their religious observances and rituals. The "Nakomse" (chief class) do not use masks. Masks in initiations and funerals is typical of all the Voltaic or Gur-speaking peoples, including the Nyonyose, Lela, Winiama, Nouna, Bwaba, and Dogon. Masks appear at burials to observe on behalf of the ancestors that proper procedures are carried out. They appear at funeral or memorial services held at regular intervals over the few years after an elder has died. Masks attend to honor the deceased and to verify that the spirit of the deceased merits admission into the world of ancestors. Without a proper funeral, the spirit remains near the home and causes trouble for his/her descendants.
