Organ Builder
Organ building is the profession of designing, building, restoring and maintaining pipe organs. The Organ builders , organ builder usually receives a commission to design an organ with a particular disposition of Organ stop, stops, Manual (music), manuals, and Tracker action, actions, creates a design to best respond to spatial, technical and acoustic considerations, and then constructs the instrument. The profession requires specific knowledge of such matters as the Scale height , scale length of organ pipes and also familiarity with the various materials used (including woods, metals, felt, and leather) and an understanding of statics, aerodynamics, mechanics and electronics. However, although in theory the builder is responsible for all facets of construction, in practice organ-building workshops include specialists in pipes, actions, and cabinets; tasks such as the manufacture of pipes, metal Casting (metalworking), casting, and making rarely-used components are often del ...

Organ Pipe
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 specific 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. Construction Materials Organ pipes are generally made out of either metal or wood. Very rarely, glass, porcelain, plastic, paper, Papier-mâché, or even stone pipes may be seen. A historical organ in the Philippines has pipes made exclusively of bamboo. Metal Metal pipes are usually made of lead; for increased rigidity it is alloyed with tin along with trace amounts of antimony and copper. The percentage of each metal in the alloy influences the characteristics of the resulting pipe. A high proportion of tin results in a slightly brighter colour (optical colour, not timbre). In addition, high amounts of tin give a glea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 ...

Craft
A craft or trade is a pastime or an occupation that requires particular skills and knowledge of skilled work. In a historical sense, particularly the Middle Ages and earlier, the term is usually applied to people occupied in small scale production of goods, or their maintenance, for example by tinkers. The traditional term ''craftsman'' is nowadays often replaced by ''artisan'' and by ''craftsperson'' (craftspeople). Historically, the more specialized crafts with high-value products tended to concentrate in urban centers and formed guilds. The skill required by their professions and the need to be permanently involved in the exchange of goods often demanded a generally higher level of education, and craftsmen were usually in a more privileged position than the peasantry in societal hierarchy. The households of craftsmen were not as self-sufficient as those of people engaged in agricultural work, and therefore had to rely on the exchange of goods. Some crafts, especially in ...

Conservation-restoration
The conservation and restoration of cultural property focuses on protection and care of cultural property (tangible cultural heritage), including artworks, architecture, archaeology, and museum collections. Conservation activities include preventive conservation, examination, documentation, research, treatment, and education. This field is closely allied with conservation science, curators and registrars. Definition Conservation of cultural property involves protection and restoration using "any methods that prove effective in keeping that property in as close to its original condition as possible for as long as possible." Conservation of cultural heritage is often associated with art collections and museums and involves collection care and management through tracking, examination, documentation, exhibition, storage, preventive conservation, and restoration. The scope has widened from art conservation, involving protection and care of artwork and architecture, to co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Casting (metalworking)
In metalworking and jewelry making, casting is a process in which a liquid metal is delivered into a mold (usually by a crucible) that contains a negative impression (i.e., a three-dimensional negative image) of the intended shape. The metal is poured into the mold through a hollow channel called a sprue. The metal and mold are then cooled, and the metal part (the ''casting'') is extracted. Casting is most often used for making complex shapes that would be difficult or uneconomical to make by other methods. Casting processes have been known for thousands of years, and have been widely used for sculpture (especially in bronze), jewelry in precious metals, and weapons and tools. Highly engineered castings are found in 90 percent of durable goods, including cars, trucks, aerospace, trains, mining and construction equipment, oil wells, appliances, pipes, hydrants, wind turbines, nuclear plants, medical devices, defense products, toys, and more. Traditional techniques include lost ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scale Height
In atmospheric, earth, and planetary sciences, a scale height, usually denoted by the capital letter ''H'', is a distance ( vertical or radial) over which a physical quantity decreases by a factor of e (the base of natural logarithms, approximately 2.718). Scale height used in a simple atmospheric pressure model For planetary atmospheres, scale height is the increase in altitude for which the atmospheric pressure decreases by a factor of ''e''. The scale height remains constant for a particular temperature. It can be calculated by H = \frac or equivalently H = \frac where: * ''k''B = Boltzmann constant = * ''R'' = gas constant * ''T'' = mean atmospheric temperature in kelvins = 250 K for Earth * ''m'' = mean mass of a molecule (units kg) * ''M'' = mean mass of one mol of atmospheric particles = 0.029 kg/mol for Earth * ''g'' = acceleration due to gravity at the current location (m/s2) The pressure (force per unit area) at a given altitude is a result of the ...

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] |
