Difference between shehnai and pungi

Shehnai is a musical instrument similar to the oboe, common in India, Pakistan, and Bangladesh. It is made out of wood, with a double reed at one end and a metal or wooden flared bell at the other end. Pungi is a wind instrument played by snake charmers on the Indian subcontinent. The instrument consists of a mouth-blown air reservoir made from a gourd, which channels air into two reedpipes.
