French Horns
The French horn (since the 1930s known simply as the horn in professional music circles) is a brass instrument made of tubing wrapped into a coil with a flared bell. The double horn in F/B (technically a variety of German horn) is the horn most often used by players in professional orchestras and bands, although the descant and triple horn have become increasingly popular. A musician who plays a horn is known as a horn player or hornist. Pitch is controlled through the combination of the following factors: speed of air through the instrument (controlled by the player's lungs and thoracic diaphragm); diameter and tension of lip aperture (by the player's lip muscles—the embouchure) in the mouthpiece; plus, in a modern horn, the operation of valves by the left hand, which route the air into extra sections of tubing. Most horns have lever-operated rotary valves, but some, especially older horns, use piston valves (similar to a trumpet's) and the Vienna horn uses double-piston valves ...

Aerophone
An aerophone is a musical instrument that produces sound primarily by causing a body of air to vibrate, without the use of strings or membranes (which are respectively chordophones and membranophones), and without the vibration of the instrument itself adding considerably to the sound (or idiophones). According to Curt Sachs: These may be lips, a mechanical reed, or a sharp edge. Also, an aerophone may be excited by percussive acts, such as the slapping of the keys of a flute or of any other woodwind. A free aerophone lacks the enclosed column of air yet, "cause a series of condensations and rarefications by various means." Overview Aerophones are one of the four main classes of instruments in the original Hornbostel–Sachs system of musical instrument classification, which further classifies aerophones by whether or not the vibrating air is contained within the instrument. The first class (41) includes instruments which, when played, do ''not'' contain the vibrating air. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Horn Techniques
Some of these horn techniques are not unique to the horn, but are applicable to most or all wind instruments. Stopped horn This is the act of fully closing off the bell of the instrument with either the right hand or a special stopping mute. This results in producing a somewhat nasal sound. When required, in the sheet music the usual notation is a '+' above the note followed by a 'o' above notes that are to be played open. For longer stopped passages, the word indicating a stopped horn is written out. The pitch lowers gradually when the hand is placed in the bell and slowly moved inward. When the bell is completely covered (stopped), the pitch falls to a half-step above the next lower partial (harmonic). For example, playing a middle C (F-horn, open) and gradually covering the bell into stopped horn, the pitch will lower a major 3rd to A (or 1/2 step above G, the next lower partial). However, playing a 3rd space C (F-horn, open) and repeating the stopped horn, the pitch will ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Octaves
In music, an octave (: eighth) or perfect octave (sometimes called the diapason) is an interval between two notes, one having twice the frequency of vibration of the other. The octave relationship is a natural phenomenon that has been referred to as the "basic miracle of music", the use of which is "common in most musical systems". The interval between the first and second harmonics of the harmonic series is an octave. In Western music notation, notes separated by an octave (or multiple octaves) have the same name and are of the same pitch class. To emphasize that it is one of the perfect intervals (including unison, perfect fourth, and perfect fifth), the octave is designated P8. Other interval qualities are also possible, though rare. The octave above or below an indicated note is sometimes abbreviated ''8a'' or ''8va'' (), ''8va bassa'' (, sometimes also ''8vb''), or simply ''8'' for the octave in the direction indicated by placing this mark above or below the staf ...

Crook (music)
A crook, also sometimes called a shank, is an exchangeable segment of tubing in a natural horn (or other brass instrument, such as a natural trumpet) which is used to change the length of the pipe, altering the fundamental pitch and harmonic series which the instrument can sound, and thus the key in which it plays. Apel, pp. 392, 926. Master crook and coupler system Early horns had unalterable lengths and permanently attached mouthpieces. This presented problems in concert situations. A different horn was required for different keys, and the instrument could not be tuned. Around 1700 the Leichnamschneider brothers in Vienna developed a horn with a removable mouthpiece that could be connected to a short piece of tubing, called a master crook. Additional pieces, couplers, of different lengths were inserted between the master crook and the body of the horn to change the horn's length, and thus the pitch. Fine-tuning was done with even shorter segments called tuning bits. This simple ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bugle (instrument)
The bugle is a simple signaling brass instrument with a wide conical bore. It normally has no valves or other pitch-altering devices, and is thus limited to its natural harmonic notes, and pitch is controlled entirely by varying the air and embouchure. History :''See also Clarion'' and '' Natural trumpet'' The English word ''bugle'' comes from a combination of words. From French, it reaches back to ''cor buglèr'' and ''bugleret'', indicating a signaling horn made from a small cow's horn. Going back further, it touches on Latin, ''buculus,'' meaning bullock. Old English also influences the modern word with ''bugle'', meaning "wild ox." The name indicates an animal's (cow's) horn, which was the way horns were made in Europe after the fall of the Western Roman Empire. The modern bugle is made from metal tubing, and that technology has roots which date back to the Roman Empire, as well as to the Middle East during the Crusades, where Europeans re-discovered metal-tube ...

Harmonics
In physics, acoustics, and telecommunications, a harmonic is a sinusoidal wave with a frequency that is a positive integer multiple of the ''fundamental frequency'' of a periodic signal. The fundamental frequency is also called the ''1st harmonic''; the other harmonics are known as ''higher harmonics''. As all harmonics are periodic at the fundamental frequency, the sum of harmonics is also periodic at that frequency. The set of harmonics forms a '' harmonic series''. The term is employed in various disciplines, including music, physics, acoustics, electronic power transmission, radio technology, and other fields. For example, if the fundamental frequency is 50 Hz, a common AC power supply frequency, the frequencies of the first three higher harmonics are 100 Hz (2nd harmonic), 150 Hz (3rd harmonic), 200 Hz (4th harmonic) and any addition of waves with these frequencies is periodic at 50 Hz. In music, harmonics are used on string instruments and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trumpet
The trumpet is a brass instrument commonly used in classical and jazz musical ensemble, ensembles. The trumpet group ranges from the piccolo trumpet—with the highest Register (music), register in the brass family—to the bass trumpet, pitched one octave below the standard B or C trumpet. Trumpet-like instruments have historically been used as signaling devices in battle or hunting, with examples dating back to the 2nd Millenium BC. They began to be used as musical instruments only in the late 14th or early 15th century. Trumpets are used in art music styles, appearing in orchestras, concert bands, chamber music groups, and jazz ensembles. They are also common in popular music and are generally included in school bands. Sound is produced by vibrating the lips in a mouthpiece, which starts a standing wave in the air column of the instrument. Since the late 15th century, trumpets have primarily been constructed of brass tubing, usually bent twice into a rounded rectangular ...

Piston Valve
A piston valve is a device used to control the motion of a fluid or gas along a tube or pipe by means of the linear motion of a piston within a chamber or cylinder. Examples of piston valves are: * The valves used in many brass instruments * The valves used for pneumatic propulsion * The valves used in many stationary steam engines and steam locomotives Brass instruments Cylindrical piston valves called Périnet valves (after their inventor François Périnet) are used to change the length of tube in the playing of most brass instruments, particularly the trumpet-like members of the family ( cornet, flugelhorn, saxhorn, etc.). Other brass instruments use rotary valves, notably the orchestral horns and many tuba models, but also a number of rotary-valved variants of those brass instruments which more commonly employ piston valves. The first piston-valved musical instruments were developed just after the start of the 19th century. The Stölzel valve (invented by H ...

Rotary Valve
A rotary valve (also called rotary-motion valve) is a type of valve in which the rotation of a passage or passages in a transverse plug regulates the flow of liquid or gas through the attached pipes. The common stopcock is the simplest form of rotary valve. Rotary valves have been applied in numerous applications, including: * Changing the pitch of brass instruments. * Controlling the steam and exhaust ports of steam engines, most notably in the Corliss steam engine. * Periodically reversing the flow of air and fuel across the open hearth furnace. * Loading sample on chromatography columns. * Certain types of two-stroke and four-stroke engines. * Most hydraulic automotive power steering control valves. Use in brass instruments In the context of brass instruments, Brass instrument valve#Rotary valve, rotary valves are found on French horn, horns, trumpets, trombones, flugelhorns, and tubas. The cornet derived from the posthorn, by applying rotary valves to it in the 1820s in Fran ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brass Instrument Valve
Brass instrument valves are valves used to change the length of tubing of a brass instrument allowing the player to reach the notes of various harmonic series. Each valve pressed diverts the air stream through additional tubing, individually or in conjunction with other valves. This lengthens the vibrating air column thus lowering the fundamental tone and associated harmonic series produced by the instrument. Valves in brass instruments require regular maintenance and lubrication to ensure fast and reliable movement. Piston valve The first musical instruments with piston valves were developed just after the start of the 19th century. Stölzel valve The first of these types was the Stölzel valve, bearing the name of its inventor Heinrich Stölzel, who first applied these valves to the French horn in 1814. Until that point, there had been no successful valve design, and horn players had to stop off the bell of the instrument, greatly compromising tone quality to achieve a parti ...

Embouchure
Embouchure () or lipping is the use of the lips, facial muscles, tongue, and teeth in playing a wind instrument. This includes shaping the lips to the mouthpiece (woodwind), mouthpiece of a woodwind or brass instrument. The word is of French language, French origin and is related to the root ', 'mouth'. Proper embouchure allows instrumentalists to play their instrument at its full range with a full, clear tone and without strain or damage to their muscles. Brass embouchure While performing on a brass instrument, the sound is produced by the player buzzing their lips into a mouthpiece. Pitches are changed in part through altering the amount of muscular contraction in the lip formation. The performer's use of the air, tightening of cheek and jaw muscles, as well as tongue manipulation can affect how the embouchure works. Maintaining an effective embouchure is an essential skill for any brass instrumentalist, but its personal and particular characteristics mean that different pedag ...

Thoracic Diaphragm
The thoracic diaphragm, or simply the diaphragm (; ), is a sheet of internal Skeletal striated muscle, skeletal muscle in humans and other mammals that extends across the bottom of the thoracic cavity. The diaphragm is the most important Muscles of respiration, muscle of respiration, and separates the thoracic cavity, containing the heart and lungs, from the abdominal cavity: as the diaphragm contracts, the volume of the thoracic cavity increases, creating a negative pressure there, which draws air into the lungs. Its high oxygen consumption is noted by the many mitochondria and capillaries present; more than in any other skeletal muscle. The term ''diaphragm'' in anatomy, created by Gerard of Cremona, can refer to other flat structures such as the urogenital diaphragm or Pelvic floor, pelvic diaphragm, but "the diaphragm" generally refers to the thoracic diaphragm. In humans, the diaphragm is slightly asymmetric—its right half is higher up (superior) to the left half, since th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
