The Algoza, common in the Tonk-Ajmer areas, is two such flutes played together. The Kathodis use the Pawri, a flute of bamboo held vertically. The Bhils use a short flute in some of their dances. Ceremonial music is provided by Nafeeri and Surnai, both rudimentrary forms of the shehnai .Then there is the Poongi of the snake charmers and its adaptation by the Langas called the Murla. Both have two tubes, one for the notes and the other for the drone.
