Atabaque

The atabaque (/ɑːtəˈbɑːkiː/; ) is a tall, wooden, Afro-Brazilian hand drum. The shell is made traditionally of Jacaranda wood from Brazil. The head is traditionally made from calfskin. A system of ropes are intertwined around the body, connecting a metal ring near the base to the head. Wooden wedges are jammed between this ring and the body and one uses a hammer to tighten or loosen the ropes, raising or lowering the pitch of the drum.
