An 8 ′ stop is said to sound at "unison pitch": the keys on the organ console produce the expected pitch (e.g. the key for middle C causes a middle C pipe to speak), like a piano. 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 ...
the row of organ pipes used to create a particular sound, more appropriately known as a rank; the sound itself; Organ stops are sorted into four major types: principal, string, reed, and flute. This is a sortable list of names that may be found associated with electronic and pipe organ stops. Countless stops have been designed over the ...
348 ranks; 19,371 pipes; The world's third largest church organ, is the largest organ in Europe. It is also the largest cathedral organ in the world. All the pipes of the organ can currently be played with the gallery console. [30] [citation needed] Italy: Duomo di Milano (Milan Cathedral) Various 15,350 pipes; 254 ranks; 185 stops
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).
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.
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.
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 ...
A cornet, or Jeu de Tierce, is a compound organ stop, containing multiple ranks of pipes. The individual ranks are, properly, of flute tone quality but can also be of principal tone. In combination, the ranks create a bright, piquant tone thought by some listeners to resemble the Renaissance brass instrument, the cornett.
