Tavil is an instrument found only in the extreme south. It has a shell of nearly spherical proportions which is open on both sides. There are two skins wrapped around two large hemp hoops. The left side is played with a stick. The right side is played with the hands with metal thimbles placed over the fingers to give a sharp sound.
This instrument is commonly played in South Indian temples, weddings, and other auspicious occasions. It is the most common accompaniment to the nadaswaram. In addition there will always be a drone. This is usually either an ottu or a hand pumped surpeti.
