Reed Pipe
A reed pipe (also referred to as a ''lingual'' pipe) is an organ pipe that is sounded by a vibrating brass strip known as a ''reed''. Air under pressure (referred to as ''wind'') is directed towards the reed, which vibrates at a specific pitch. This is in contrast to flue pipes, which contain no moving parts and produce sound solely through the vibration of air molecules. Reed pipes are common components of pipe organs. Stop Reed pipes include all stops of the "Reed" class, and some stops from the "Hybrid" class. The reed stops of an organ are collectively called the "reed-work". Construction A reed pipe comprises a metal ''tongue'' (the reed) which rests against a ''shallot'', in which is carved a tunnel. The reed and shallot are held in place by a wooden ''wedge''. This assembly protrudes from the underside of the ''block'' and hangs down into the ''boot''. A ''tuning wire'' is inserted through the boot and is bent to hold the reed against the shallot. The wire is moved up ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Woodwind Instrument
Woodwind instruments are a family of musical instruments within the greater category of wind instruments. Common examples include flute, clarinet, oboe, bassoon, and saxophone. There are two main types of woodwind instruments: flutes and reed instruments (otherwise called reed pipes). The main distinction between these instruments and other wind instruments is the way in which they produce sound. All woodwinds produce sound by splitting the air blown into them on a sharp edge, such as a reed or a fipple. Despite the name, a woodwind may be made of any material, not just wood. Common examples include brass, silver, cane, as well as other metals such as gold and platinum. The saxophone, for example, though made of brass, is considered a woodwind because it requires a reed to produce sound. Occasionally, woodwinds are made of earthen materials, especially ocarinas. Flutes Flutes produce sound by directing a focused stream of air below the edge of a hole in a cylindrical tu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Miter Joint
A mitre joint (often miter in American English) is a joint made by cutting each of two parts to be joined, across the main surface, usually at a 45° angle, to form a corner, usually to form a 90° angle, though it can comprise any angle greater than 0 degrees. It is called beveling when the angled cut is done on the side, although the resulting joint is still a mitre joint. For woodworking, a disadvantage of a mitre joint is its weakness, but it can be strengthened with a spline (a thin wafer of wood inserted into a slot, usually arranged with the long grain of the spline across the short grain of the frame timber). There are two common variations of a splined mitre joint, one where the spline is long and runs the length of the mating surfaces and another where the spline is perpendicular to the joined edges. Common applications include picture frames, pipe Pipe(s), PIPE(S) or piping may refer to: Objects * Pipe (fluid conveyance), a hollow cylinder following certain di ...

Timbre
In music, timbre ( ), also known as tone color or tone quality (from psychoacoustics), is the perceived sound quality of a musical note, sound or tone. Timbre distinguishes different types of sound production, such as choir voices and musical instruments. It also enables listeners to distinguish different instruments in the same category (e.g., an oboe and a clarinet, both woodwind instruments). In simple terms, timbre is what makes a particular musical instrument or human voice have a different sound from another, even when they play or sing the same note. For instance, it is the difference in sound between a guitar and a piano playing the same note at the same volume. Both instruments can sound equally tuned in relation to each other as they play the same note, and while playing at the same amplitude level each instrument will still sound distinctively with its own unique tone color. Experienced musicians are able to distinguish between different instruments of the same typ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Expression Pedal
An expression pedal is an important control found on many musical instruments including organs, electronic keyboards, and pedal steel guitar. The musician uses the pedal to control different aspects of the sound, commonly volume. Separate expression pedals can often be added to a guitar amplifier or effects unit and used to control many different aspects of the tone. Because the source of power with a pipe organ and electronic organs is not generated by the organist, the volume of these instruments has no relationship with how hard its keys or pedals are struck; i.e., the organ produces the same volume whether the key or pedal is depressed gently or firmly. Moreover, the tone will remain constant in pitch, volume, and timbre until the key or pedal is lifted, at which point the sound stops. The expression pedal gives the organist control over the external source of power, and thus the volume, of the instrument, while leaving the user's hands free. This system of dynamic control ...

Organist
An organist is a musician who plays any type of organ. An organist may play solo organ works, play with an ensemble or orchestra, or accompany one or more singers or instrumental soloists. In addition, an organist may accompany congregational hymn-singing and play liturgical music. Classical and church organists The majority of organists, amateur and professional, are principally involved in church music, playing in churches and cathedrals. The pipe organ still plays a large part in the leading of traditional western Christian worship, with roles including the accompaniment of hymns, choral anthems and other parts of the worship. The degree to which the organ is involved varies depending on the church and denomination. It also may depend on the standard of the organist. In more provincial settings, organists may be more accurately described as pianists obliged to play the organ for worship services; nevertheless, some churches are fortunate to have trained organists capable ...

Pump Organ
The pump organ is a type of free-reed organ that generates sound as air flows past a vibrating piece of thin metal in a frame. The piece of metal is called a reed. Specific types of pump organ include the reed organ, harmonium, and melodeon. The idea for the free reed was imported from China through Russia after 1750, and the first Western free-reed instrument was made in 1780 in Denmark. More portable than pipe organs, free-reed organs were widely used in smaller churches and in private homes in the 19th century, but their volume and tonal range were limited. They generally had one or sometimes two manuals, with pedal-boards being rare. The finer pump organs had a wider range of tones, and the cabinets of those intended for churches and affluent homes were often excellent pieces of furniture. Several million free-reed organs and melodeons were made in the US and Canada between the 1850s and the 1920s, some of which were exported. The Cable Company, Estey Organ, and Mason & ...

Accordion
Accordions (from 19th-century German ''Akkordeon'', from ''Akkord''—"musical chord, concord of sounds") are a family of box-shaped musical instruments of the bellows-driven free-reed aerophone type (producing sound as air flows past a reed in a frame), colloquially referred to as a squeezebox. A person who plays the accordion is called an accordionist. The concertina , harmoneon and bandoneón are related. The harmonium and American reed organ are in the same family, but are typically larger than an accordion and sit on a surface or the floor. The accordion is played by compressing or expanding the bellows while pressing buttons or keys, causing ''pallets'' to open, which allow air to flow across strips of brass or steel, called '' reeds''. These vibrate to produce sound inside the body. Valves on opposing reeds of each note are used to make the instrument's reeds sound louder without air leaking from each reed block.For the accordion's place among the families of mu ...

Harmonica
The harmonica, also known as a French harp or mouth organ, is a free reed wind instrument used worldwide in many musical genres, notably in blues, American folk music, classical music, jazz, country, and rock. The many types of harmonica include diatonic, chromatic, tremolo, octave, orchestral, and bass versions. A harmonica is played by using the mouth (lips and tongue) to direct air into or out of one (or more) holes along a mouthpiece. Behind each hole is a chamber containing at least one reed. The most common is the diatonic Richter-tuned with ten air passages and twenty reeds, often called the blues harp. A harmonica reed is a flat, elongated spring typically made of brass, stainless steel, or bronze, which is secured at one end over a slot that serves as an airway. When the free end is made to vibrate by the player's air, it alternately blocks and unblocks the airway to produce sound. Reeds are tuned to individual pitches. Tuning may involve changing a reed’s len ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
En Chamade
''En chamade'' (French: "to sound a parley") refers to powerfully voiced reed stops in a pipe organ that have been mounted horizontally, rather than vertically, in the front of the organ case, projecting out into the church or concert hall. They produce a commanding, loud trumpet-like tone, used for fanfares and solos. It is known as Fan Trumpet, Horizontal Trumpet, and Trompette en Chamade. Any stop mounted ''en chamade'' will be much louder than a stop elsewhere in the organ, even though in church organs the stops may stand on the same windpressure. In theatre and concert organs, ''en chamade'' stops often stand on higher windpressure than the other stops, to sound even more powerful and commanding. History First seen in Iberian and Mexican organs of the early eighteenth century, it came in many forms to create choruses in divided registers: the ''Trompeta de Batalla'' (8′), ''Bajoncillo'' (4′), ''Bajo'' (16′), ''Violeta'' (2′), ''Trompeta Magna'' (16′), the ''Clar ...

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 (music), 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 organ stop, stops. A pipe organ has one or more keyboards (called ''Manual (music), manuals'') played by the hands, and a pedal keyboard, 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 Organ console, ''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 be ...

Molecules
A molecule is a group of two or more atoms held together by attractive forces known as chemical bonds; depending on context, the term may or may not include ions which satisfy this criterion. In quantum physics, organic chemistry, and biochemistry, the distinction from ions is dropped and ''molecule'' is often used when referring to polyatomic ions. A molecule may be homonuclear, that is, it consists of atoms of one chemical element, e.g. two atoms in the oxygen molecule (O2); or it may be heteronuclear, a chemical compound composed of more than one element, e.g. water (two hydrogen atoms and one oxygen atom; H2O). In the kinetic theory of gases, the term ''molecule'' is often used for any gaseous particle regardless of its composition. This relaxes the requirement that a molecule contains two or more atoms, since the noble gases are individual atoms. Atoms and complexes connected by non-covalent interactions, such as hydrogen bonds or ionic bonds, are typically not c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
