Shehnai is a double reed oboe, common in India, Pakistan, Bangladesh and Iran, made out of wood, with a metal flare bell at the end. Its sound is thought to create and maintain a sense of auspiciousness and sanctity and, as a result, is widely used during marriages, processions, and in temples, although it is also played in concerts. This tubular instrument gradually broadens towards the lower end. It usually has between six and nine holes. It employs one set of quadruple reeds, making it a quadruple reed woodwind. By controlling the breath, various tunes can be played on it. The shehnai has a range of two octaves, from the A below middle C to the A one line above the treble clef.Soak the reed in water for 12 hours before playing.
