== Form and use == It is composed of a stretched skin over a hollow container that serves as a resonance box (which may be a can, a jug, a wooden cylinder or similar). The center of the skin is pierced by a wood stick or a reed, and the sound is obtained by moving the rod downward and upward, so that the rod rubs the stretched skin. This rod may sometimes be replaced with a rope. When the rod is rubbed with both hands, the vibration produced by the rod is transmitted to the skin, creating a deep and peculiar sound.
