Timila, thimila or paani, is an hour-glass shaped percussion instrument used in Kerala, South India. It is made of polished jackwood, and the drumheads made of calfskin (preferably taken from 1-2 year old calf) are held together by leather braces which are also twined round the waist of the drum. This mechanism helps in adjusting the tension and controlling the sound, mainly two: 'tha' and 'thom'. It is one of the constituting instruments in Panchavadyam. It is also a major percussion instrument used in sree-bali, sree-bhootha-bali and related temple rites.
