Woodwind Instruments have a prominent place in Persian classical music orchestras as well as in rural and urban music. For example Ney is an oblique, rim-blown flute and has a unique, sad and at the same time soothing sound. It is the only wind instrument in the Persian orchestra. The Persian ney is made of reed of 40 to 80 cm long, with seven nodes. There are five finger-holes and one thumb-hole producing the basic pitches. Other pitches are produced by varying the breath pressure.
