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.
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.
Organ pipes are so sensitive to temperature that the body heat of the organ tuner can affect the tuning. If one holds a small metal flue pipe briefly in one's hand and then returns it to the chest ( windchest ), its pitch (relative to a tuning reference) can be heard to change as the pipe returns to room temperature.
On April 26, 1941 Ray Nelson entertained fans that showed up early with a pipe organ behind the ballpark's grandstands. The Chicago Tribune notes that Nelson had to cut the music before the first ...
Pedalboards range in size from 13 notes on small spinet organs designed for in-home use (an octave, conventionally C 2 –C 3) to 42 notes (three and a half octaves, G 1 –C 5) on church or concert organs. Modern pipe organs typically have 30- or 32-note pedalboards, while some electronic organs and many older pipe organs have 25-note pedalboards.
Today this organ may be a pipe organ (see above), a digital or electronic organ that generates the sound with digital signal processing (DSP) chips, or a combination of pipes and electronics. It may be called a church organ or classical organ to differentiate it from the theatre organ , which is a different style of instrument.
The organ at the Naval Academy Chapel has 522 stops. The pitch produced by an organ pipe is a function of its length. All else equal, longer pipes produce lower-pitched notes, and shorter pipes are higher in pitch. An organ stop uses a set (rank) of pipes of graduated lengths to produce the range of notes needed.
the control on an organ console that selects a particular sound; 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 ...
