====Things that have been described as a reed ====

Bullroarer \\
Jaw Harp \\
Free Reeds- acordian, harmonica, melodica, reed organs, sheng \\ 
Lamell Reeds- Clarinet or saxophone Reeds \\
Double Reeds- Oboe, Shawm, Bassoon \\
Crushed Double Reeds- Duduk, Guanzi, Hichiriki \\
Membranophone- A double chamber where air passes from the outer chamber into the inner chamber which is a tube by forcing open a membrane that is under tension. \\ 
Invert reed- Like lips playing into a brass instrument (these are invert because its two edges that are forced open instead of forced closed like on a double reed) 
Grass Blade- This is a Air activated ribbon (a type of string) \\ 
 
====Previous Definitions====
Summarized from Wikipedia and Encyclopedia Britannica 


This definition has a major issue in that is describes single reeds (lamell reeds like those of a clarinet or saxophone) as well as free reeds (like those of a harmonica) but inadequacy describes the behavior of double reeds (or any other class listed above) because the focus is on the shape of the material. 
====My New Definition ====

A reed is any solid material that vibrates in a stable and consistent manner in response to wind as the generating force of the oscillation. 
===Understanding the distinction ===

Wind --> Material that vibrates in response --> Sound is directed into a resonating tube (air column with standing waves) \\
Wind --> An edge that causes an oscillation --> Sound is generated by an Air Column with standing Waves or a Helmholtz resonator with pressure waves with Cavity Resonance ((http://hyperphysics.phy-astr.gsu.edu/hbase/Waves/cavity.html)) \\
