For those interested in the technical details of organ reeds
(the beating type used in pipe organs), there is a book entitled
"The Organ Reed" by N. A. Bonavia-Hunt that is interesting reading.

There is a great deal of material as to the theory and operation of
the reed pipe mechanism and the factors that produce the various reed
tones such as reed material, reed curvature, resonator characteristics,
etc.  There is also a section on making and voicing reeds for the
adventurous types.
