Ransingha
The nansingha or nansinga is a type of primitive trumpet made of copper or copper alloys, used in both India and Nepal. The instrument is made of two metal curves, joined to form an "S" shape. It may also be reassembled to form a crescent.
It is part of a group of curved-tube instruments that include the ransingha, the narsinga and the sringa. It may also be related to the laawaa and Tibetan dungchen, both straight tubular copper horns.
