Cornet (organ Stop)
A cornet, or Jeu de Tierce, is a compound organ stop, containing multiple ranks of pipes. The individual ranks are, properly, of flute tone quality but can also be of principal tone. In combination, the ranks create a bright, piquant tone thought by some listeners to resemble the Renaissance brass instrument, the cornett The cornett, cornetto, or zink is an early wind instrument that dates from the Medieval, Renaissance and Baroque periods, popular from 1500 to 1650. It was used in what are now called alta capellas or wind ensembles. It is not to be confused wi .... A cornet stop usually starts at middle C, distinguishing it from the sesquialtera, which has pipes for the full compass of the manual. A sesquialtera is also usually softer in tone. The cornet is primarily used as a solo voice and the ranks of the cornet follow the harmonic series; 8', 4', 2', 2', 1' (fundamental, octave, 12th, 15th, 17th respectively). The 8' rank is stopped while the other ranks are open. The c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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, ...

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] |
Flue Pipe
A flue pipe (also referred to as a ''labial'' pipe) is an organ pipe that produces sound through the vibration of air molecules, in the same manner as a recorder or a whistle. Air under pressure (called ''wind'') is driven through a flue and against a sharp lip called a ''labium'', causing the column of air in the pipe to resonate at a frequency determined by the pipe length (see wind instrument). Thus, there are no moving parts in a flue pipe. This is in contrast to reed pipes, whose sound is driven by beating reeds, as in a clarinet. Flue pipes are common components of pipe organs. Stop Flue pipes include all stops of the "Principal", "Flute", and "String" classes, and some stops from the "Hybrid" class. Construction Flue pipes may be metallic or wooden. Metal pipes are usually circular in cross section; wooden pipes are usually square or rectangular, though triangular and round wooden pipes do exist. A flue pipe has two major parts, a foot and a resonator. The ''foot'' i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cornett
The cornett, cornetto, or zink is an early wind instrument that dates from the Medieval, Renaissance and Baroque periods, popular from 1500 to 1650. It was used in what are now called alta capellas or wind ensembles. It is not to be confused with the modern cornet. The sound of the cornett is produced by lip vibrations against a cup mouthpiece, similar to modern brass instruments. A cornett consists of a conical wooden pipe covered in leather, is about long, and has finger holes and a small horn, ivory, or bone mouthpiece. The range is from A3 to A5, however the bottom note can be lipped as far as G3 and a good player can get up to E6. Construction The ordinary treble cornett is made by splitting a length of wood and gouging out the two halves to make the gently conical, curved bore. The halves are then glued together, and the outside planed to an octagonal cross section, the whole being bound in thin black leather. Six front finger holes and a thumb hole on the back (like on ...

Sesquialtera (organ Stop)
Sesquialtera ('one and a half') may refer to: * Sesquialterum in mathematics, the ratio 3:2, a superparticular ratio * Sesquialtera or the equivalent Greek term hemiola, three in the time of two as variously used in music theory: ** Sesquialtera commonly describes a tempo proportion in mensural notation ** Hemiola is more common for the temporary substitution of a 2+2+2 musical meter In music, metre (British English, Commonwealth spelling) or meter (American and British English spelling differences#-re, -er, American spelling) refers to regularly recurring patterns and accents such as bar (music), bars and Beat (music), beats ... for 3+3 * Sesquialtera (organ stop), combining mutation ranks at 2' and 1', i.e. both 3:2 and 5:4 pitch ratios * ''Sesquialtera'' (moth), a genus of moth in the family Geometridae {{disambiguation ...

Mixture (organ Stop)
A mixture is an organ stop, usually of principal tone quality, that contains multiple ranks of pipes including at least one mutation stop. It is designed to be drawn with a combination of stops that forms a complete chorus (for example, principals of 8′, 4′, and 2′ pitches). The mixture sounds the upper harmonics of each note of the keyboard, adding a chord to each note played. The individual pitches in the mixture are not distinguished by the listener; rather, they reinforce the fundamental pitches of the chorus, adding volume and brilliance to the sound. Because pipes playing upper harmonics produce their own set of harmonic overtones, an element of harmonic dissonance is introduced, giving mixtures their characteristic tonal texture as they enrich the ensemble. Historically, the mixture descends from the medieval Blockwerk concept, an organ in which there were no stops and all the ranks sounded simultaneously. Nomenclature Mixture stops are typically labeled i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
