The Chenda (, ) is a cylindrical percussion instrument used widely in the state of Kerala, Tulu Nadu of Karnataka and Tamil Nadu in India. In Tulu Nadu it is known as chande.
A Chenda is a cylindrical wooden drum, and has a length of two feet and a diameter of one foot. Both ends are covered (usually with animal's skin) with the "Chenda Vattam". The animal skin is usually of a cow ( Heifer), in a traditional Chenda other skins are not used (skin of bull, ox etc. are not used), to have a quality sound the skin from the abdominal part of the cow is taken. The Chenda is suspended from the drummers neck so that it hangs vertically. Though both sides can be used for playing, only one is actually beaten. Using two sticks, the drummer strikes the upper parchment.
This instrument is famous for its loud and rigid sound. A Chenda has two sides, the left side called " Edamthala" (ഇടം തല)(Left Head) and the right side " Valamthala" (വലം തല)(Right Head). 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 (Chenda Vattam, ചെണ്ട വട്ടം) 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, boiled for an entire day and then bent in the form of circle and dried up. The body of the Chenda which is 1 ft in diameter and 1.5 inches thickness is made of the soft wood of the jackfruit tree (വരിക്ക പ്ലാവ്) (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 artists 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. In Kerala the craft of making Chenda is now associated with some few "Perumkollan" ( smith) families at Peruvembu, Nemmara, Lakkidi, Vellarkad and Valappaya villages. Many famous Chenda percussionists in Kerala make their Chendas from Vellarkad village for it is famous for the quality of the instrument.
