Sarronca

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.

• In some zones in Spain, zambomba refers to the typical Christmas celebrations in which people sing villancicos while playing this instrument.
• In the autonomous community of Andalusia, mainly in the province of Málaga, zambomba is a term used to describe techno electronic music, in its faster and more obscure branches, generally, acid techno and schranz. This connotation has its origins in a collective called AstralTech, that promotes these musical standards considered obsolete by current tendencies in electronic music. This term is used due to the similarities of the sounds.
