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. Each pipe is tuned to a note of the musical scale. A set of organ pipes of similar timbre comprising the complete scale is known as a rank; one or more ranks constitutes a stop.
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 ranks second in the world based on number of pipes. [11] It is the largest fully operational musical instrument in the world, with the weight of 287 tons. This concert organ was initially constructed for the 1904 World's Fair in St. Louis ; it was designed by George Ashdown Audsley .
For example, an 8′ Gedeckt may also be made available as a 4′ Gedeckt, either on the same or a different manual. When both of these stops are selected and a key (for example, C 3) is pressed, two pipes of the same rank will sound: the pipe normally corresponding to the key played (C 3), and the pipe one octave above that (C 4).
A mixture is an organ stop, usually of principal tone quality, that contains multiple ranks of pipes including at least one mutation stop.It is designed to be drawn with a combination of stops that forms a complete chorus, for example, principals of 8 foot (8 ′), 4 ′, and 2 ′ pitches.
Möller thought that anybody who wanted a pipe organ should be able to get one. So, the company built many "Portable" (3 ranks of pipes) and "Artiste" instruments (3 to 9 ranks), smaller mass-produced organs which incorporated standard specifications with fewer sets of pipes.
Certain stops called mixtures contain multiple ranks of pipes sounding at consecutive octaves and fifths (and in some cases, thirds) above unison pitch. The number of ranks in a mixture is denoted by a Roman numeral on the stop knob; for example, a stop labeled "Mixture V" would contain five pipes for every note. So for every key pressed, five ...
The 8', 3 + 1 ⁄ 5 ', and 2' ranks use flared and tapered pipes, and the 2 + 2 ⁄ 3 ' uses harmonic pipes. The 4' pipes are double languid. The 4' pipes are double languid. [ 3 ] : 108–109 The Grand Cornet was fully restored and brought back on line in 2023, returning "a signature clang" to the tone quality of the instrument.
