Nadaswaram

The nadaswaram (Tamil: ) (Malayalam: ) is a double reedwind instrument from Tamil Nadu. It is used as a traditional classical instrument in Tamil Nadu, Andhra Pradesh, Telangana, Karnataka, Kerala and in the northern and eastern parts of Sri Lanka.

This instrument is "among the world's loudest non-brass acoustic instruments". It is a wind instrument partially similar to the North Indianshehnai, but much longer, with a hardwood body, and a large flaring bell made of wood or metal, and also with a double reed rather than a quadruple reed.

In South Indian culture, the nadasvaram is considered to be very auspicious, and it is a key musical instrument played in almost all Hindu weddings and temples of the South Indian tradition. It is part of the family of instruments known as mangala vadyam (lit. mangala "auspicious", vadya "instrument"). The instrument is usually played in pairs, and accompanied by a pair of drums called thavil; it can also be accompanied by a drone from a similar oboe, called the ottu.
