Congos also known as tumbadora, is a tall, narrow, single-headed drum from Cuba. Congos have a staved wooden or fiberglass shell, and a screw-tensioned drumhead. They are usually played in sets of two to four with the fingers and palms of the hand. Typical congas stand approximately 75 centimetres (30 in) from the bottom of the shell to the head. The drums may be played while seated.
