Nadaswaram

The Nadaswaram (nādḥasvaram) is a double reed wind instrument from South India. It is used as a traditional classical instrument in Tamil Nadu, Andhra Pradesh, Telangana, Karnataka and Kerala and in the North and East 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 Indian shehnai, but much longer, with a hardwood body, and a large flaring bell made of wood or metal.

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 with a drone from a similar oboe, called the ottu.
