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.
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.
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 ...
The choir division of the organ at St. Raphael's Cathedral, Dubuque, Iowa.Wood and metal pipes of a variety of sizes are shown in this photograph. An organ pipe is a sound-producing element of the pipe organ that resonates at a specific pitch when pressurized air (commonly referred to as wind) is driven through it.
Ophicleide (/ ˈ ɒ f ɪ k l aɪ d / OFF-ih-klyde) and Contra Ophicleide are powerful pipe organ reed pipes used as organ stops. The name comes from the early brass instrument, the ophicleide, forerunner of the euphonium. The Ophicleide is generally at 16 ft pitch, and the Contra Ophicleide at 32 ft.
The pitch of a single bank of reeds is traditionally defined in a similar manner to the organ stops of a pipe organ.A bank that sounds at unison pitch when keys are depressed is called 8′ (pronounced "eight-foot") pitch: alluding to the length of the lowest-sounding organ pipe in that rank, which is approximately eight feet.
Reed A reed stop at 8 ft pitch on the manuals with a tone similar to that of a bassoon. Dulciana Dulziana String An 8 ft pitch metal string stop. Usually the softest stop on an organ.
