A frame drum is a type of drum where the drumhead is wider than it is deep. It is one of the oldest musical instruments and may be the first drum ever created. The drum has one head, often made from animal skin, though other materials are sometimes used. Some frame drums use mechanical tuning, while others have the drumhead attached with tacks. The drumhead is stretched over a round wooden frame called a shell. The shell is usually made from bent wood like rosewood, oak, or ash, joined together. Some shells are made from plywood or other man-made materials. Metal rings or jingles might also be added to the frame. In many cultures, larger frame drums are often played by men during spiritual ceremonies, while medium-sized drums are usually played by women.
