Fig. 18. Haskell's Clarinet Without Reed

In the last half-century the art of reed voicing has been entirely revolutionized. Prior to the advent of Willis, organ reeds were poor, thin, buzzy things, with little or no grandeur of effect, and were most unmusical in quality. Testimony to the truth of this fact is to be found in old instruction books for organ students. It is there stated that reeds should never be used alone, but that a Stopped Diapason or other rank of flue pipes must always be drawn with them to improve the tone quality.
