context_page_description: A reed is a thin strip of material that vibrates to produce a sound on a musical instrument. Most woodwind instrument reeds are made from Arundo donax or synthetic material. Tuned reeds are made of metal or synthetics. Musical instruments are classified according to the type and number of reeds.
  The earliest types of single-reed instruments used idioglottal reeds, where the vibrating reed is a tongue cut and shaped on the tube of cane. Much later, single-reed instruments started using heteroglottal reeds, where a reed is cut and separated from the tube of cane and attached to a mouthpiece of some sort. By contrast, in an uncapped double reed instrument, there is no mouthpiece; the two parts of the reed vibrate against one another.
context_section_description: Quadruple reed instruments have four reeds, two on top and two on bottom. Examples of this include an archetypal instrument from India, the shehnai, as well as the pi from Thailand, and the Cambodian sralai. Having four reeds instead of two produces a very different tone and set of harmonics.
