A reed pipe comprises a metal tongue (the reed) which rests against a shallot, in which is carved a tunnel. The reed and shallot are held in place by a wooden wedge. This assembly protrudes from the underside of the block and hangs down into the boot. A tuning wire is inserted through the boot and is bent to hold the reed against the shallot.
In a rank of stopped pipes, the lowest pipe is 4 feet in length but sounds at unison pitch—that is, at the same pitch as an 8 ′ open pipe—so it is known as an 8 ′ stop. Reed pipes are also labeled the same as that of an open pipe with the same pitch, regardless of the actual length of the pipe.
Scaling is the ratio of an organ pipe's diameter to its length. The scaling of a pipe is a major influence on its timbre. Reed pipes are scaled according to different formulas than for flue pipes. In general, the larger the diameter of a given pipe at a given pitch, the fuller and more fundamental the sound becomes.

Such tuning is extremely stable, but causes gradual damage to the pipe over time. Reed pipes may be tuned in any of several ways: (1) by lengthening or shortening the vibrating length of the reed tongue by means of a wire protruding from the boot of the pipe; (2) by adjusting the effective speaking length of the resonator; (3) by adjusting the ...
A stop which speaks at unison pitch, or "native pitch", is known as an 8′ (pronounced "eight-foot") stop. This nomenclature refers to the approximate length of the longest pipe in a rank of open pipes. In a rank of stopped pipes, the lowest pipe is about 4 feet long, but because it sounds at unison pitch, it is also known as an 8′ stop.
