Pungi fifty years ago. However, prior to this it derived from Indian folk music and was used for religious purposes for snake charming. The pungi is traditionally made from a dried bottle gourd. Often, the neck of the gourd is carved for aesthetic reasons. On the other end, two (sometimes one or three) reed or bamboo pipes are connected. These are known as the "jivala". One of the pipes has 5 - 9 holes and plays the melody; the other pipe is for drone. The jivala is fitted to the gourd with beeswax, which can be adjusted for pitch modification. The
Wind instrument a half-wavelength. To a rough approximation, a tube of about 40 cm. will exhibit resonances near the following points: In practice, however, obtaining a range of musically useful tones from a wind instrument depends to a great extent on careful instrument design, and playing technique. The frequency of the vibrational modes depends on the speed of sound in air, which varies with air density. A change in temperature, and only to a much smaller degree also a change in humidity, influences the air density and thus the speed of sound, and therefore affects the tuning of wind instruments. The effect
