wind system distribution Explanation: Wind system A view from behind the organ of St. Raphael's Cathedral in Dubuque, Iowa. One of the wind trunks is visible under the windchest. An organ's wind system comprises the parts that produce, store, and deliver wind to the pipes. The pressure of the wind supply is measured by a manometer. In the United States and United Kingdom, wind pressure is described in "inches of water"; in other countries, the metric "millimetres of water" is often used instead. Although the phrase is scientifically incorrect, pipe organs are said to be "on x inches (of wind)".[13][14] The exact wind pressure depends on the design of the organ. An Italian organ from the Renaissance period may only be on 2.2 inches (56 mm),[15] while certain stops in a large twentieth-century organ can feature wind pressures as high as 100 inches (2540 mm).[16] Wind was originally produced by mechanical means. When signalled by the organist (often by a small bell), a calcant would operate a set of bellows, supplying them with air.[17] Therefore, playing the organ before electricity required at least one person to operate the bellows. Because calcants were expensive, organists would usually practice on smaller instruments that required no external energy source, such as the clavichord or harpsichord.[18] Beginning in the late nineteenth century, electric motors called blowers were used to fill the bellows with air. This made it possible for organists to practice regularly on the organ. Most organs, both new and historic, have electric blowers, though some organs' wind systems can be operated manually. The wind supply is stored in one or more reservoirs to maintain a constant wind pressure. The wind flows from the bellows to the various windchests through one or more large tubes called wind trunks. It is stored there until the action allows it to flow into the pipes. Action The term action may refer to either a key action, which admits wind into a pipe when a key is depressed, or a stop action, which allows the organist to control which ranks are engaged. An action may be either mechanical or electrical.[9] A key action which physically connects the keys and the windchests is called a mechanical action or a tracker action. This connection is achieved through a series of wooden or metal rods called trackers. When the organist depresses a key, the corresponding tracker moves, allowing wind to enter the pipe.[ http://en.wikipedia.org/wiki/Pipe_organ#Pipes |
