Tubular-pneumatic Action
"Tubular-pneumatic action" refers to an apparatus used in many pipe organs built during the late 19th and early 20th centuries. The term "tubular" refers to the extensive use of lead tubing to connect the organ's console to the valves that control the delivery of "wind" (air under pressure) to the organ's pipes. Many such organs are extant 100 or more years after their construction. Description In any organ, each pipe has a valve located at its foot which responds to the organist's commands from the console's keyboard, pedalboard and stop controls. These valves are contained in windchests upon which the organ's pipework is set. Any type of apparatus that connects an organ's console with its windchest is referred to as its "action". An organ that utilizes tubular-pneumatic action is commonly called a "tubular-pneumatic organ". It seems the first use of this action was in 1851, in Willis' Great Exhibition organ, though it was only very limited. It appears that the first organ usi ...

Pipe Organ
The pipe organ is a musical instrument that produces sound by driving pressurized 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 and volume throughout the keyboard compass. Most organs have many ranks of pipes of differing timbre, pitch, and volume that the player can employ singly or in combination through the use of controls called stops. A pipe organ has one or more keyboards (called '' manuals'') played by the hands, and a pedal clavier played by the feet; each keyboard controls its own division, or group of stops. The keyboard(s), pedalboard, and stops are housed in the organ's ''console''. The organ's continuous supply of wind allows it to sustain notes for as long as the corresponding keys are pressed, unlike the piano and harpsichord whose sound begins to dissipate immediately after a key is depressed.

Direct Electric Action
Direct electric action is one of various systems used in pipe organs to control the flow of air (wind) into the organ's pipes when the corresponding keys or pedals are depressed. In direct electric action, the valves beneath the pipes are opened directly by electro-magnet solenoids, while with electro-pneumatic action, the electro-magnet's action admits air into a pneumatic or small bellows which in turn operates the pipe's valve. Other types of actions used in pipe organs are tracker action, using mechanical linkage of rods and levers, and tubular-pneumatic action "Tubular-pneumatic action" refers to an apparatus used in many pipe organs built during the late 19th and early 20th centuries.

Electro-pneumatic Action
The electro-pneumatic action is a control system by the mean of air pressure for pipe organs, whereby air pressure, controlled by an electric current and operated by the keys of an organ console, opens and closes valves within wind chests, allowing the pipes to speak. This system also allows the console to be physically detached from the organ itself. The only connection was via an electrical cable from the console to the relay, with some early organ consoles utilizing a separate wind supply to operate combination pistons. Invention Although early experiments with Barker lever, tubular-pneumatic and electro-pneumatic actions date as far back as the 1850s, credit for a feasible design is generally given to the English organist and inventor, Robert Hope-Jones.George Laing Miller (1909).

Sir John Stainer
Sir John Stainer (6 June 1840 – 31 March 1901) was an English composer and organist whose music, though seldom performed today (with the exception of ''The Crucifixion'', still heard at Passiontide in some churches of the Anglican Communion), was very popular during his lifetime. His work as choir trainer and organist set standards for Anglican church music that are still influential. He was also active as an academic, becoming Heather Professor of Music at Oxford. Stainer was born in Southwark, London, in 1840, the son of a schoolmaster. He became a chorister at St Paul's Cathedral when aged ten and was appointed to the position of organist at St Michael's College, Tenbury at the age of sixteen. He later became organist at Magdalen College, Oxford, and subsequently organist at St Paul's Cathedral. When he retired owing to his poor eyesight and deteriorating health, he returned to Oxford to become Professor of Music at the university. He died unexpectedly while on holiday ...

George Ashdown Audsley
George Ashdown Audsley (September 6, 1838 – June 21, 1925) was an accomplished architect, artist, illustrator, writer, decorator and pipe organ designer who excelled in many artistic fields but is perhaps best known today for having designed the Wanamaker Organ in Philadelphia. Life Born September 6, 1838, in Elgin, Scotland, Audsley apprenticed with A. & W. Reid, architects there. In 1856, he followed his older brother, William James Audsley to Liverpool, England, and was employed by architect John Weightman. By 1860, Audsley & Co., architects and makers of mounts and passe-partout, was established. The firm was eventually named W. & G. Audsley and completed ten churches in the Gothic Revival Style in the Liverpool area. An eclectic style was used for synagogues built in Liverpool and London. The firm's secular buildings, such as the Layton Art Gallery in Milwaukee, WI, USA, closely followed the style of Alexander Thomson (1817-1875), featuring Greek, Egyptian and Hind ...

Henry Willis
Henry Willis (27 April 1821 – 11 February 1901), also known as "Father" Willis, was an English organ player and builder, who is regarded as the foremost organ builder of the Victorian era. His company Henry Willis & Sons remains in business. Early life and work Willis was born in London, the son of a North London builder, and with George Cooper, later sub-organist of St Paul's Cathedral, he learned to play the organ with some help from Thomas Attwood, St Paul's organist. In 1835, Willis was articled to organ builder John Gray (later of Gray and Davison) for seven years. During this time, he invented the manual and pedal couplers which he used throughout his later career. Following his apprenticeship he worked for three years in Cheltenham, assisting an instrument maker, Wardle Evans, who specialised in free reed instruments. Willis later attributed his personal skill in reed voicing to this experience. Willis met Samuel Sebastian Wesley at Cheltenham, and this led to t ...

Tracker Action
Tracker action is a term used in reference to pipe organs and steam calliopes to indicate a mechanical linkage between keys or pedals pressed by the organist and the valve that allows air to flow into pipe(s) of the corresponding note. This is in contrast to "direct electric action" and "electro-pneumatic action", which connect the key to the valve through an electrical link or an electrically assisted pneumatic system respectively, or "tubular-pneumatic action" which utilizes a change of pressure within lead tubing which connects the key to the valve pneumatic. History Ancient history Organs trace their history as far back as at least the 3rd century BC with an organlike device known as the hydraulis. Also known as a "water organ" or "Roman organ", the hydraulis was an instrument in which water was used as a source of power to push wind through organ pipes. (It is not to be confused with the hydraulic action of a hydraulophone, an instrument that actually uses water to produ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Organ Console
The pipe organ is played from an area called the console or keydesk, which holds the manuals (keyboards), pedals, and stop controls. In electric-action organs, the console is often movable. This allows for greater flexibility in placement of the console for various activities. Some very large organs, such as the van den Heuvel organ at the Church of St. Eustache in Paris, have more than one console, enabling the organ to be played from several locations depending on the nature of the performance. Controls at the console called stops select which ranks of pipes are used. These controls are generally either draw knobs (or stop knobs), which engage the stops when pulled out from the console; stop tablets (or tilting tablets) which are hinged at their far end; or rocker-tablets, which rock up and down on a central axle. Different combinations of stops change the timbre of the instrument considerably. The selection of stops is called the registration. On modern organs, the registr ...

Organ Stop
An organ stop is a component of a pipe organ that admits pressurized air (known as ''wind'') to a set of organ pipes. Its name comes from the fact that stops can be used selectively by the organist; each can be "on" (admitting the passage of air to certain pipes), or "off" (''stopping'' the passage of air to certain pipes). The term can also refer to the control that operates this mechanism, commonly called a stop tab, stop knob, or drawknob. On electric or electronic organs that imitate a pipe organ, the same terms are often used, with the exception of the Hammond organ and clonewheel organs, which use the term "Hammond organ#Drawbars, drawbar". The term is also sometimes used as a synonym for register, referring to rank(s) of pipes controlled by a single stop. Registration (organ), Registration is the art of combining stops to produce a certain sound. The phrase "wikt:pull out all the stops, pull out all the stops,” while once only meant to engaging all voices on the organ, ...
