The atabaque (/ɑːtəˈbɑːkiː/; Brazilian Portuguese: [ataˈbaki]) 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. Because of this tuning mechanism the drum is sometimes known as 'Atabaque de Corda'.
