Yogis play this copper instrument at Changu Narayan Jaatraa and at the Melaa of Swargadwari and Goshainkunda. At Changu Narayan temple it is played during daily ritual ceremonies. It is also played at several other temples. The Naagphani’s shape is like that of a very convoluted snake. It is 63cm long, with a mouthpiece at the tail end and a forked tongue in the snake’s mouth where the sound emerges. By altering the balance of the mouthpiece on lip and tongue the musician can play a range of notes.
