Royal Kete drums Asante Ghana

"The term Kete refers to […] a specific drum ensemble, a type of music, and a manner of dance found in the Ashanti Region of Ghana. […] Although almost every level of chief has drums, Kete is solely the privilege of paramount chiefs and the Asantehene, the titular head of Ashanti. The Kete drummers are in the service of the chief and hold a position in the royal court. The drums themselves are owned by the chief and are considered one of the marks of his office.
They are played only for court-related functions unless the chief gives special permission for them to be played elsewhere. For example, the Kete ensemble always plays at the funeral of the chief or members of the royal lineage but would not normally play at the funeral of a commoner."
