Nadaswarm

The nadaswaram (also spelt nadhaswaram, and also called nagaswaram) is one of the most popular classical instruments of South India and the world's loudest non-brass acoustic instrument. It is a wind instrument similar to the North Indian shehnai but larger, with a hardwood body and a large flaring bell made of wood or metal.
In India the nadaswaram is considered to be very auspicious, and it is the key instrument which is played in almost all Hindu marriages and temples in South India. The instrument is usually played in pairs, and accompanied by a pair of drums called thavil.
The nadaswaram contains three parts namely, kuzhal, thimiru, and anasu. Traditionally the body of the nagaswaram is made out of a tree called aacha.
Some of the greatest early exponents of the nadaswaram include Thiruvavadudurai Rajaratnam Pillai and Sangita Kalanidi Thiruvizhimizhalai Subrahmanya Pillai. In more recent times Namagiripettai Krishnan, Karukurichi Arunachalam, Sheik Chinna Moulana, Thiruvarur S Latchappa Pillai are well known nadaswaram artists.
