Write a note on the origin of the Shehnai.
Emperor Aurangzeb had banned the usage of pungi in the royal residence as it had a shrill unpleasent sound. It also became a generic name for all the reeded noisemakers. So, a barber of a family of professional musicians, who had access to the royal palace, improved the tonal quality of pungi by first choosing a pipe with a natural hollow stem that was longer and broader than the pungi and made 7 holes on the body of the pipe. That produced a melodious sound. The instrument as was first played in the shah's chamber and was played by a nai(barber) was named ''shehnai."
