The Boehm system is a system of keywork for the flute, created by inventor and flautist Theobald Boehm between 1831 and 1847. [1] [2] [3]
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 operated). Boehm also wanted to locate tone holes at acoustically optimal points on the body of the instrument, rather than locations conveniently covered by the player's fingers. To achieve these goals, Boehm adapted a system of axle-mounted keys with a series of "open rings" (called brille, German for "eyeglasses", as they resembled the type of eyeglass frames common during the 19th century) that were fitted around other tone holes, such that the closure of one tone hole by a finger would also close a key placed over a second hole.
In 1832 Boehm introduced a new conical-bore flute, which achieved a fair degree of success. Boehm, however, continued to look for ways to improve the instrument. Finding that an increased volume of air produced a stronger and clearer tone, he replaced the conical bore with a cylindrical bore, finding that a parabolic contraction of the bore near the embouchure hole improved the instrument's low register. He also found that optimal tone was produced when the tone holes were too large to be covered by the fingertips, and he developed a system of finger plates to cover the holes. These new flutes were at first made of silver, although Boehm later produced wooden versions.
The cylindrical Boehm flute was introduced in 1847, with the instrument gradually being adopted almost universally by professional and amateur players in Europe and around the world during the second half of the 19th century. The instrument was adopted for the performance of orchestral and chamber music, opera and theater, wind ensembles (e.g., military and civic bands), and most other music which might be loosely described as relating to "Western classical music" (including, for example, jazz). Many further refinements have been made, and countless design variations are common among flutes today (the "offset G" key, addition of the low B foot, etc.) The concepts of the Boehm system have been applied across the range of flutes available, including piccolos, alto flutes, bass flutes, and so on, as well as other wind instruments. The material of the instrument may vary (many piccolos are made of wood, some very large flutes are wooden or even made of PVC).
The flute is perhaps the oldest musical instrument, other than the human voice itself. There are very many flutes, both traversely blown and end-blown "fipple" flutes, currently produced which are not built on the Boehm model.
The fingering system for the saxophone closely resembles the Boehm system. A key system inspired by Boehm's for the clarinet family is also known as the "Boehm system", although it was developed by Hyacinthe Klosé and not Boehm himself. The Boehm system was also adapted for a small number of flageolets. Boehm did work on a system for the bassoon, and Boehm-inspired oboes have been made, but non-Boehm systems remain predominant for these instruments. The Albert system is another key system for the clarinet.
The bassoon is a musical instrument in the woodwind family, which plays in the tenor and bass ranges. It is composed of six pieces, and is usually made of wood. It is known for its distinctive tone color, wide range, versatility, and virtuosity. It is a non-transposing instrument and typically its music is written in the bass and tenor clefs, and sometimes in the treble. There are two forms of modern bassoon: the Buffet and Heckel systems. It is typically played while sitting using a seat strap, but can be played while standing if the player has a harness to hold the instrument. Sound is produced by rolling both lips over the reed and blowing direct air pressure to cause the reed to vibrate. Its fingering system can be quite complex when compared to those of other instruments. Appearing in its modern form in the 19th century, the bassoon figures prominently in orchestral, concert band, and chamber music literature, and is occasionally heard in pop, rock, and jazz settings as well. One who plays a bassoon is called a bassoonist.
The clarinet is a single-reed musical instrument in the woodwind family, with a nearly cylindrical bore and a flared bell.
The flute is a member of a family of musical instruments in the woodwind group. Like all woodwinds, flutes are aerophones, producing sound with a vibrating column of air. Unlike woodwind instruments with reeds, a flute produces sound when the player's air flows across an opening. In the Hornbostel–Sachs classification system, flutes are edge-blown aerophones. A musician who plays the flute is called a flautist or flutist.
The oboe is a type of double-reed woodwind instrument. Oboes are usually made of wood, but may also be made of synthetic materials, such as plastic, resin, or hybrid composites.
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. 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 of other materials include brass, silver, cane, and 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.
The piccolo is a half-size flute and a member of the woodwind family of musical instruments. Sometimes referred to as a "baby flute" or piccolo flute, the modern piccolo has the same type of fingerings as the standard transverse flute, but the sound it produces is an octave higher. This has given rise to the name ottavino, by which the instrument is called in Italian and thus also in scores of Italian composers.
The bass clarinet is a musical instrument of the clarinet family. Like the more common soprano B♭ clarinet, it is usually pitched in B♭, but it plays notes an octave below the soprano B♭ clarinet. Bass clarinets in other keys, notably C and A, also exist, but are very rare. Bass clarinets regularly perform in orchestras, wind ensembles and concert bands, and occasionally in marching bands, and play an occasional solo role in contemporary music and jazz in particular.
A fife is a small, high-pitched, transverse aerophone, that is similar to the piccolo. The fife originated in medieval Europe and is often used in fife and drum corps, military units, and marching bands. Someone who plays the fife is called a fifer. The word fife comes from the German Pfeife, meaning pipe, which comes from the Latin word pipare.
The rackett, raggett, cervelas, or sausage bassoon is a Renaissance-era double reed wind instrument, introduced late in the sixteenth century and already superseded by bassoons at the end of the seventeenth century.
The alto flute is an instrument in the Western concert flute family, pitched below the standard C flute and the uncommon flûte d'amour. It is the third most common member of its family after the standard C flute and the piccolo. It is characterized by its rich, mellow tone in the lower portion of its range. The bore of the alto flute is considerably larger in diameter and longer than the C flute and requires a larger column of air (volume of air) from the player, though it also requires a slower airspeed. This gives it a greater dynamic presence in the bottom octave and a half of its range. Its range is from G3 (the G below middle C) to G6 (4 ledger lines above the treble clef staff) plus an altissimo register stretching to D♭7. It uses the same fingerings as the C flute and piccolo, but is a transposing instrument in G (sounding a perfect fourth lower than written).
Theobald Böhm was a German inventor and musician, who greatly improved the modern Western concert flute and its fingering system. He was a Bavarian court musician, a virtuoso flautist and a renowned composer.
The Western concert flute is a family of transverse (side-blown) woodwind instruments made of metal or wood. It is the most common variant of the flute. A musician who plays the flute is called a “flautist” in British English, and a “flutist” in American English.
The Irish flute is a conical-bore, simple-system, wooden flute of the type favoured by classical flautists of the early 19th century, or to a flute of modern manufacture derived from this design. The majority of traditional Irish flute players use a wooden, simple-system flute.
The guan is a Chinese double reed wind instrument. The northern Chinese version is called guanzi or bili and the Cantonese version is called houguan. It is classified as a bamboo instrument in the Ba Yin system. Unlike other instruments in the double-reed family of woodwinds which mostly have conical bores, such as the Chinese suona or the Western oboe, the guan has a cylindrical bore, giving its distinctive mellow, yet piercing buzz-like timbre.
In music, fingering, or on stringed instruments sometimes also called stopping, is the choice of which fingers and hand positions to use when playing certain musical instruments. Fingering typically changes throughout a piece; the challenge of choosing good fingering for a piece is to make the hand movements as comfortable as possible without changing hand position too often. A fingering can be the result of the working process of the composer, who puts it into the manuscript, an editor, who adds it into the printed score, or the performer, who puts his or her own fingering in the score or in performance.

In music, the bore of a wind instrument 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.
The Boehm system for the clarinet is a system of clarinet keywork, developed between 1839 and 1843 by Hyacinthe Klosé and Auguste Buffet jeune. The name is somewhat deceptive; the system was inspired by Theobald Boehm's system for the flute, but necessarily differs from it, since the clarinet overblows at the twelfth rather than the flute's octave. Boehm himself was not involved in its development.
The five-key flute is a musical instrument once common in school marching bands, and composed of wood with metal keys. It is a transposing instrument, most commonly in A♭, this variant being known as the B♭ flute, named after its lowest note and sounding a minor sixth below the orchestral piccolo. The next most common variants are the E♭ piccolo, sounding a fifth above the B♭ flute, and the F flute, sounding a fifth below the B♭ flute. The E♭ piccolo is used for ornamentation in melodies and the F flute is used as a bass instrument in flute band harmonies. They are now often found in British military corps of drums, often playing various regimental marches.
Reed aerophones is one of the categories of musical instruments found in the Hornbostel-Sachs system of musical instrument classification. In order to produce sound with these Aerophones the player's breath is directed against a lamella or pair of lamellae which periodically interrupt the airflow and cause the air to be set in motion.
