Tabla is a pair of drums. It consists of a small right-hand drum called a Dayan and a larger metal drum called a Bayan. The dayan (right drum) is made of wood. The bayan (left drum) made of copper or brass or steel with a nickel or chrome plate is the most common material. Both come with goatskin drum heads and camel leather straps to adjust the pitch. Black spot on tabla skin is a mixture of rubber, soot and iron filings. Your satisfaction is our priority. We want you to be 100% satisfied with our products and our service.
