Nagphani or the serpent horn is a traditional instrument of Uttarakhand, Rajasthan and Gujarat. It is a brass horn/trumpet that is stylized as a serpent, with four tight coils. The tail serves as the mouthpiece, where the player buzzes their lips. The serpent-shaped head serves as the bell and has a forked tongue extending out of the bell. The movement of this metal tongue and embouchure (buzzing lips) adjustments, both support a variety of pitches. The nagphani is used by tantrik ritual performers during ritual ceremonies, story tellers and street performers. Apart from social occasions, the instrument was also played during battles to boost the morale of the troops.
