An organ pipe is a sound-producing element of the pipe organ that resonates at a specific pitch when ... A pipe with a wide diameter will tend to produce a flute tone ...
The wider the pipe, the greater the suppression. Thus, other factors being equal, wide pipes are poor in harmonics, and narrow pipes are rich in harmonics. The scale of a pipe refers to its width compared to its length, and an organ builder will refer to a flute as a wide-scaled stop, and a string-toned gamba as a narrow-scaled stop.
The diameter of a flue pipe directly affects its tone. When comparing pipes of otherwise identical shape and size, a wide pipe will tend to produce a flute tone, a medium pipe a diapason tone, and a narrow pipe a string tone. These relationships are referred to as the scale of the pipe: i.e., wide-scaled, normal-scaled, or narrow-scaled. As a ...
The pipe organ is a musical instrument that produces sound by driving pressurised air (called wind) through the organ pipes selected from a keyboard.Because each pipe produces a single pitch, the pipes are provided in sets called ranks, each of which has a common timbre, volume, and construction throughout the keyboard compass.
It is a large-scale, stopped wood flute pipe, usually with a leathered lip. The rank was invented by Robert Hope-Jones. Tibia Clausas provides the basic foundation tone of the organ with few overtones or harmonics. The Tibia Clausa is arguably the most important rank of pipes in a theatre pipe organ, [1] with some
Bourdon is a stopped pipe, having an airtight stopper fitted into the top. This makes the tone one octave lower than a pipe of open construction (they are only one half the length of an open pipe of the same pitch), and also eliminates the development of even-numbered harmonics (" squaring off " the timbre), helping to create the characteristic ...

An organ pipe, or a harpsichord string, designated as eight-foot pitch (8′) is sounded at standard, ordinary pitch. [1] For example, the A above middle C in eight-foot pitch would be sounded at 440 Hz (or at some similar value, depending on how concert pitch was set at the time and place the organ or harpsichord was made).
