Its analogue in Rajasthan is known as the madga and pani mataqa. The ghatam is one of the most ancient percussion instruments of South India. It is a clay pot with narrow mouth. Made mainly of clay backed with brass or copper filings with a small amount of iron filings, the size of the ghatam varies according to its pitch.
