In Zimbabwean music, the mbira is a musical instrument consisting of a wooden board to which staggered metal keys have been attached. It is often fitted into a deze that functions as a resonator. Mbira performances are usually accompanied by hosho. The Mbira is usually classified as part of the lamellophone family of musical instruments.
