The Recent Revolution in Organ Building / Being an Account of Modern Developments

REEDS.

As remarked in our opening chapter, pipes with strips of cane or reeds in the mouthpiece are of great antiquity, being found side by side with the flutes in the Egyptian tombs. These reeds, as those used at the present day, were formed of the outer siliceous layer of a tall grass, Arundo donax, or sativa, which grows in Egypt and the south of Europe. They were frequently double, but the prototype of the reed organ-pipe is to be seen in the clarinet, where the reed is single and beats against the mouthpiece. Of course, an artificial mouthpiece has to be provided for our organ-pipe, but this is called the boot. See Figure 19, which shows the construction of a reed organ-pipe. A is the boot containing a tube called the eschallot B, partly cut away and the opening closed by a brass tongue C, which vibrates under pressure of the wind. D is the wire by which the tongue is tuned; E the body of the pipe which acts as a resonator.
