Timila

There are special caps for the fingers to produce a harsher sound

Timila, thimila or paani, (Malayalam: തിമില) is an hour-glass shaped drum used in Kerala, South India. Usually, the instrument is made of wood. It is often used with religious ceremonies. Sometimes four different percussion instruments (one of them the Timila), and a trumpet are grouped. Such a group is called Panchavadyam.
