The Mridangam is a double-sided drum. The body of the instrument is made of one piece of wood. Hollow, the body has two opertures of different size, one very small, that will generate high-pitched sounds and another, wide, for low-pitched sounds. The walls of the instrument are 2/3 centiments thick and give it stability in the low frequencies. The goatskin, coupled to the high pitch opeture, wears a thick black disk made of flour, ferric oxide powder and starch stuck to its centre to allow the emission of harmonics. The skin coupled to the bas operture is coated in its middle with plain flour paste to give it a perfect tune. The two skins are stretched together with leather strips. The Mridangam is the main rhythm instrument of Carnatic Music- Music with Ghatam.
