Cylindrical Bore
In music, the bore of a wind instrument (including woodwind and brass) is its interior chamber. This defines a flow path through which air travels, which is set into vibration to produce sounds. The shape of the bore has a strong influence on the instrument's timbre. Bore shapes The cone and the cylinder are the two idealized shapes used to describe the bores of wind instruments. Other shapes are not generally used, as they tend to produce dissonant, anharmonic overtones and an unmusical sound. Instruments may consist of a primarily conical or cylindrical tube, but begin in a mouthpiecs, and end in a rapidly-expanding "flare" or "bell". This flare reduces the acoustic impedance mismatch between the instrument and the air, allowing the instrument to transmit sound to the air more effectively. These shapes affect the prominence of harmonics associated with the timbre of the instrument. A bore that flares from the mouthpiece reduces resistance to the breath, while a bore that n ...

Trumpet
The trumpet is a brass instrument commonly used in classical and jazz ensembles. The trumpet group ranges from the piccolo trumpet—with the highest 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 at least 1500 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, for instance in orchestras, concert bands, and jazz ensembles, as well as in popular music. They are played by blowing air through nearly-closed lips (called the player's embouchure), producing a "buzzing" sound that starts a standing wave vibration in the air column inside the instrument. Since the late 15th century, trumpets have primarily been constructed of brass tubing, usually bent twice into a rounded rectangular shape. There are many distinc ...

Harmonic Series (music)
A harmonic series (also overtone series) is the sequence of harmonics, musical tones, or pure tones whose frequency is an integer multiple of a ''fundamental frequency''. Pitched musical instruments are often based on an acoustic resonator such as a string or a column of air, which oscillates at numerous modes simultaneously. At the frequencies of each vibrating mode, waves travel in both directions along the string or air column, reinforcing and canceling each other to form standing waves. Interaction with the surrounding air causes audible sound waves, which travel away from the instrument. Because of the typical spacing of the resonances, these frequencies are mostly limited to integer multiples, or harmonics, of the lowest frequency, and such multiples form the harmonic series. The musical pitch of a note is usually perceived as the lowest partial present (the fundamental frequency), which may be the one created by vibration over the full length of the string or air co ...

Recorder (musical Instrument)
The recorder is a family of woodwind musical instruments in the group known as ''internal duct flutes'': flutes with a whistle mouthpiece, also known as fipple flutes. A recorder can be distinguished from other duct flutes by the presence of a thumb-hole for the upper hand and seven finger-holes: three for the upper hand and four for the lower. It is the most prominent duct flute in the western classical tradition. Recorders are made in various sizes with names and compasses roughly corresponding to various vocal ranges. The sizes most commonly in use today are the soprano (also known as descant, lowest note C5), alto (also known as treble, lowest note F4), tenor (lowest note C4), and bass (lowest note F3). Recorders were traditionally constructed from wood or ivory. Modern professional instruments are almost invariably of wood, often boxwood; student and scholastic recorders are commonly of molded plastic. The recorders' internal and external proportions vary, but the bore i ...

Boehm System
The Boehm system is a system of keywork for the flute, created by inventor and flautist Theobald Boehm between 1831 and 1847. History Immediately prior to the development of the Boehm system, flutes were most commonly made of wood, with an inverse conical bore, eight keys, and tone holes (the openings where the fingers are placed to produce specific notes) that were small in size, and thus easily covered by the fingertips. Boehm's work was inspired by an 1831 concert in London, given by soloist Charles Nicholson who, with his father in the 1820s, had introduced a flute constructed with larger tone holes than were used in previous designs. This large-holed instrument could produce greater volume of sound than other flutes, and Boehm set out to produce his own large-holed design. In addition to large holes, Boehm provided his flute with "full venting", meaning that all keys were normally open (previously, several keys were normally closed, and opened only when the key was oper ...

Flute
The flute is a family of classical music instrument in the woodwind group. Like all woodwinds, flutes are aerophones, meaning they make sound by vibrating a column of air. However, unlike woodwind instruments with reeds, a flute is a reedless wind instrument that produces its sound from the flow of air across an opening. According to the instrument classification of Hornbostel–Sachs, flutes are categorized as edge-blown aerophones. A musician who plays the flute is called a flautist or flutist. Flutes are the earliest known identifiable musical instruments, as paleolithic examples with hand-bored holes have been found. A number of flutes dating to about 53,000 to 45,000 years ago have been found in the Swabian Jura region of present-day Germany. These flutes demonstrate that a developed musical tradition existed from the earliest period of modern human presence in Europe.. Citation on p. 248. * While the oldest flutes currently known were found in Europe, Asia, too, has ...

Crumhorn
The crumhorn is a double reed instrument of the woodwind family, most commonly used during the Renaissance period. In modern times, particularly since the 1960s, there has been a revival of interest in early music, and crumhorns are being played again. It was also spelled krummhorn, krumhorn, krum horn, and cremorne. Terminology The name derives from the German ''Krumhorn'' (or ''Krummhorn'' or ''Krumporn'') meaning ''bent horn''. This relates to the old English ''crumpet'' meaning curve, surviving in modern English in 'crumpled' and 'crumpet' (a curved cake). The similar-sounding French term cromorne, when used correctly, refers to a woodwind instrument of different design, though the term cromorne is often used in error synonymously with that of crumhorn. It is uncertain if the Spanish wind instrument ''orlo'' (attested in an inventory of 1559) designates the crumhorn, but it is known that crumhorns were used in Spain in the sixteenth century, and the identification seems l ...

Cornamuse
The cornamuse is a double reed instrument dating from the Renaissance period. It is similar to the crumhorn in having a windcap over the reed and cylindrical bore. The only evidence for the cornamuse comes from a description and a few comments by Michael Praetorius in ''Syntagma musicum'' II, published in 1619. Since the paragraph by Praetorius is the only clear description of the cornamuse and no period specimen or picture has been found, all reconstructions of the instrument rely on a certain amount of conjecture. The text in German reads "Die CornaMuse sind gleich aus/und nicht mit doppelten/sondern mit einer einfachen Röhre/gleich den Bassanelli €¦aber unten zugedackt / und uff der seiten herumb etliche löcherlein / dadurch der Resonanz herausser gehet. Am klang seynd sie gar den Krumbhörnern gleich / nur dass sie stiller / lieblicher und gar sanft klingen €¦ (''The cornamuse are similar to/and do not have a double, but rather a single tube (bore)/like the bassanelli'' ...

Clarinet
The clarinet is a musical instrument in the woodwind family. The instrument has a nearly cylindrical bore and a flared bell, and uses a single reed to produce sound. Clarinets comprise a family of instruments of differing sizes and pitches. The clarinet family is the largest such woodwind family, with more than a dozen types, ranging from the BBâ™­ contrabass to the Eâ™­ soprano. The most common clarinet is the B soprano clarinet. German instrument maker Johann Christoph Denner is generally credited with inventing the clarinet sometime after 1698 by adding a register key to the chalumeau, an earlier single-reed instrument. Over time, additional keywork and the development of airtight pads were added to improve the tone and playability. Today the clarinet is used in classical music, military bands, klezmer, jazz, and other styles. It is a standard fixture of the orchestra and concert band. Etymology The word ''clarinet'' may have entered the English language via the Fr ...

Chalumeau
The chalumeau (; ; plural chalumeaux) is a single-reed woodwind instrument of the late baroque and early classical eras. The chalumeau is a folk instrument that is the predecessor to the modern-day clarinet. It has a cylindrical bore with eight tone holes (seven in front and one in back for the thumb) and a broad mouthpiece with a single heteroglot reed (''i.e.'' separate, not a continuous part of the instrument's body) made of cane. Similar to the clarinet, the chalumeau overblows a twelfth. History The word ''chalumeau'' first begins to appear in writing during the 1630s, but may have been in use as early as the twelfth century. Several French dictionaries in the sixteenth century use the word to refer to various types of simple, idioglot reed-pipes all with tone holes. The heteroglot style reed was later adopted in the seventeenth and into the eighteenth centuries. These single-pipe instruments probably evolved from earlier multiple-pipe instruments through the a ...

Wind Instrument
A wind instrument is a musical instrument that contains some type of resonator (usually a tube) in which a column of air is set into vibration by the player blowing into (or over) a mouthpiece set at or near the end of the resonator. The pitch of the vibration is determined by the length of the tube and by manual modifications of the effective length of the vibrating column of air. In the case of some wind instruments, sound is produced by blowing through a reed; others require buzzing into a metal mouthpiece, while yet others require the player to blow into a hole at an edge, which splits the air column and creates the sound. Methods for obtaining different notes * Using different air columns for different tones, such as in the pan flute. These instruments can play several notes at once. * Changing the length of the vibrating air column by changing the length of the tube through engaging valves ''(see rotary valve, piston valve)'' which route the air through additional tubing ...

Overblowing
Overblowing is the manipulation of supplied air through a wind instrument that causes the sounded pitch to jump to a higher one without a fingering change or the operation of a slide. Overblowing may involve a change in the air pressure, in the point at which the air is directed, or in the resonance characteristics of the chamber formed by the mouth and throat of the player. (The latter is a feature of embouchure.) In some instruments, overblowing involves the direct manipulation of the vibrating reed(s), and/or the pushing of a register key while otherwise leaving fingering unaltered. With the exception of harmonica overblowing, the pitch jump is from one vibratory mode of the reed or air column, e.g., its fundamental, to an overtone. Overblowing can be done deliberately in order to get a higher pitch, or inadvertently, resulting in the production of a note other than intended. Characteristics In simple woodwind instruments, overblowing can cause the pitch to change into a ...

Octave
In music, an octave ( la, octavus: eighth) or perfect octave (sometimes called the diapason) is the interval between one musical pitch and another with double its frequency. 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'' ( it, all'ottava), ''8va bassa'' ( it, all'ottava bassa, sometimes also ''8vb''), or simply ''8'' for the octave in the direction indicated by placing ...
