This instrument is famous for its loud and rigid sound. A Chenda has two sides, the left side called “Edamthala” and the right side “Valamthala”. The “Edamthala” is made of only one/two layer of cow skin and the “Valamthala” will have a five/seven layer skin, so as to have a bass sound. The skin are dried under shadow and fastened on wooden rings made of the trunk of a locally available palm tree (Eeranpana) or bamboo, using a gum prepared from the seed of a tree called “pananchi maram”. The circular frame is kept in a vessel and boiled for a whole long day and then bended in the form of circle and drying it up. The body of the Chenda which is 2 ft 36 inches diameter and 1.5 inches thickness is made of the soft wood of the jackfruit tree (Varikka Plavu). The thickness is again reduced by 0.25 inches, at simultaneous points separated by 4 inches. This is done in order to produce highly resonating sound. Only the wooden rings with the skin (Chenda Vattam) is replaced once the quality of the sound is not up to the mark. For regular Chenda artistes an average of 15 rings are required every year.
The Chenda is mainly played in Hindu temple festivals and as an accompaniment in the religious art forms of Kerala. The chenda is used as an accompaniment for Kathakali, Koodiyattam, Kannyar Kali, Theyyam and among many forms of dances and rituals in Kerala. It is also played in a dance-drama called Yakshagana (Tenku Thittu) which is popular in Tulu Nadu of Karnataka. There is a variant of this instrument used in northern school of Yakshagana called Chande. It is traditionally considered to be an Asura Vadyam ((demonic instrument)) which means it cannot go in harmony. Chenda is an unavoidable musical instrument in all form of cultural activities in Kerala.
