 The choir division of the organ at St. Raphael's Cathedral, Dubuque, Iowa. Wood and metal pipes of a variety of sizes are shown in this photograph. Organ pipes are the sound-producing elements of the pipe organ. These resonators are made of either wood or metal that produce sound when air under pressure (commonly referred to as wind) is allowed through it. Each pipe is tuned to a specific note of the musical scale. Image File history File linksMetadata StRaphaelsDubOrganSmall. ...

Pipe varieties Flue pipes and Reed pipes are by far the most common organ pipes, and variations on these are found on every instrument. Diaphone pipes are also made, but these are very rare, and found on only a handful of pipe organs around the world. Organ pipes are categorised according to the construction style of each pipe, variables of which include the mechanism, materials, and structure of the pipe.
Flue pipes -
Flue pipes (or flues), also referred to as labial pipes, contain no moving parts. They produce sound by the use of whistles or fipples (in a similar manner to a recorder. The majority of pipes in most organs are flue pipes. Flue pipes are themselves divided into three broad classes: In a pipe organ, a flue pipe is any pipe that is sounded by a fipple, similar to that in a whistle or a flute a bec, rather than by a beating reed, see reed pipe. ...
A fipple mouthpiece uses a narrow windway and a blade-like edge to channel and vibrate air blown into it. ...
Various recorders The recorder is a woodwind musical instrument of the family known as fipple flutes or internal duct flutes—whistle-like instruments which include the tin whistle and ocarina. ...
- Flute pipes have the purest tones, and are generally the widest-scaled flue pipes.
- Diapasons are intermediate in tone, and represent the fundamental sound of the pipe organ.
- String pipes have the richest harmonics, and tend to be the narrowest pipes.
The word diapason (pronounced ) is another name for the musical interval of the octave, especially in the context of Pythagorean intervals. ...
In a pipe organ, a string stop is an organ stop that uses a single rank of narrow, conical or tapered flue pipes to produce a bright sound, rich in harmonics. ...
Reed pipes -
Reed pipes (or reeds), also referred to as lingual pipes, are driven by a beating reed. Diagram of typical reed pipe A Reed pipe is a type of pipe found in pipe organs qualified by the use of a vibrating metal strip instead of the simple vibration of air. ...
A reed is a thin strip of material which vibrates to make music. ...
Diaphone pipes The diaphone is a unique and uncommon organ pipe. Invented by Robert Hope-Jones around 1900, it has characteristics of both flue pipes and reed pipes. The pipe speaks through a resonator, much like a reed pipe, but a pallet instigates the vibration instead of a reed. The pipe is generally of wooden construction (although some examples of metal diaphones exist) and can be voiced on various wind pressures. The diaphone is usually found at 16′ and 32′ pitches, however there are a few examples of 8′ diaphones, and a full-length 64′ Diaphone-Dulzian is installed in the Boardwalk Hall Auditorium Organ in Atlantic City (which is one of only two full-length 64′ stops in the world, the other being the Contra Trombone reed stop in the organ at the Sydney Town Hall in Sydney, Australia). Robert Hope-Jones (9 February 1859 in Hooton Grange, Cheshire – 13 September 1914 in Rochester, New York, USA)) is considered to be the inventor of the theatre organ. ...

Hope-Jones also developed an imitative version called the diaphonic horn, which had a more reed-like quality than the diaphone and was voiced on lower wind pressures. Wurlitzer built a version for their theater organs at 32′ and 16′ pitches with huge wooden resonators as extensions of its Diaphonic diapason, and at 16′ with metal resonators as an extension of its smaller-scale Open diapason. The Austin Organ Company also developed a metal diaphone at 16′ pitch known as a Magnaton. In addition to its usage in the pipe organ, the diaphone has also been used in foghorns and fire signals due to its penetrating tone. The Rudolph Wurlitzer Company, usually referred to simply as Wurlitzer, is an American company, formerly a producer of stringed instruments, woodwind, brass instruments, theatre organs, band organs, orchestrions, electric pianos and jukeboxes. ...

Pipe construction
Materials Organ pipes are generally made out of either wood or metal. Metal flue pipes are usually made of varying mixtures of lead and tin, depending on the requirements sought for that particular pipe. The more lead used in the alloy, the darker the resulting tone will be. Conversely, if a pipe has a high proportion of tin, it will have a brighter tone. In addition, high amounts of tin give a gleaming and long-lasting polish which may be required if the pipe is clearly visible. Pure lead is too soft to be used alone; stiffening agents such as antimony and copper must be added for increased rigidity. Additionally, hammering sheets of pure lead increases strength. The cost of each metal is also a factor, with tin being of far greater expense than lead. The usual exceptions to tin-lead alloys are very lowest pipes in a rank, which are sometimes made of rolled zinc. In addition, pipes have been made of many metals, including gold, silver, aluminum, brass, copper, and iron. Very rarely, glass, porcelain, plastic, or even stone pipes may be seen.
Metal pipes are made by first casting a metal alloy onto a long flat surface. This alloy is usually a mixture of lead and tin, with trace amounts of other metals. Once the metal dries, it is cut into pieces, which are then rolled into shapes around molds (mandrels) and welded together. Wooden pipes are made by cutting wood into the required shapes and sizes and assembling the pieces together. An alloy is a combination, either in solution or compound, of two or more elements, at least one of which is a metal, and where the resulting material has metallic properties. ...

Mandrel (pronounced mandrul, and also transliterated as manderil) is a term that can refer to: an object used to shape machined work; a tool component that grips or clamps materials to be machined; or a tool component that can be used to grip other moving tool components. ...
Shape Organ pipes are generally made in three shapes: cylindrical, conical, and square/rectangular. There are some irregular shapes that appear as well (the Flûte triangulaire, for example, is a triangular-shaped flue pipe). In addition to this, a pipe can be tapered from top to bottom.
End construction An organ pipe can be either open or closed (also known as stopped) at the end opposite the reed or mouth. An open pipe produces a tone in which both the even-numbered and the odd-numbered partials are present, while a stopped pipe produces a tone with only the odd-numbered partials. See Harmonic series (music) Harmonic series (mathematics) These two concepts are related. ...
A stop tuned to unison pitch is known as an 8′ stop ("eight foot"). This refers to the approximate speaking length of the longest open flue pipe of that stop, sounding C (the C two octaves below middle C). It is these 8′ stops which sound at the same pitch as a piano. A 4′ stop (so called because its C pipe is approximately four feet long) speaks an octave above an 8′ stop. In a pipe organ, a flue pipe is any pipe that is sounded by a fipple, similar to that in a whistle or a flute a bec, rather than by a beating reed, see reed pipe. ...
In Western music, the expression middle C refers to the note C or Do located exactly between the two staves of the grand staff, quoted as C4 in note-octave notation (also known as scientific pitch notation). ...
A stopped pipe is one in which the top end of the pipe is blocked ("stopped") meaning the air travels up and back down the pipe, doubling the length of the sound column. This means a stopped pipe of 4′ length will sound as an 8′ stop. This has many space saving advantages as well as varying tone qualities available. This would mean that the longest pipe in an 8′ Stopped Diapason is actually only 4′ long. A gedackt is another example of a stopped pipe. Gedackt (also spelled gedeckt) is the name of a family of stops in pipe organ building. ...
Stopped pipes tend to be gentler and sweeter in tone than open pipes, though this is largely at the discretion of the voicer. Stopped pipes are also used in situations in which there is limited space and/or money available, and a full-length rank of pipes (especially bass pipes of 16′ and 32′ length) would take up too much space and/or be too costly to build. It is quite common for the lowest few notes of an otherwise open rank of pipes to be stopped for this reason.

A pipe's tone color can be affected to certain degrees by many variables. The degree to which a particular variable affects a pipe's tone color depends upon whether the pipe is of the flue or reed variety. More important than any of these considerations, however, is the way in which the organ builder voices the pipes during installation. A skilled pipe voicer can coax a stunning variety of sounds out of one pipe. In music, timbre is the quality of a musical note which distinguishes different types of musical instrument. ...
