Clarinet
–
The clarinet is a musical-instrument family belonging to the group known as the woodwind instruments. It has a mouthpiece, a straight cylindrical tube with an almost cylindrical bore. A person who plays a clarinet is called a clarinetist, the word clarinet may have entered the English language via the French clarinette, or from Provençal clarin, oboe. It would seem however that its roots are to be found amongst some of the various names for trumpets used around the renaissance. Clarion, clarin and the Italian clarino are all derived from the medieval term claro which referred to a form of trumpet. This is probably the origin of the Italian clarinetto, itself a diminutive of clarino, according to Johann Gottfried Walther, writing in 1732, the reason for the name is that it sounded from far off not unlike a trumpet. The English form clarinet is found as early as 1733, while the similarity in sound between the earliest clarinets and the trumpet may hold a clue to its name, other factors may have been involved. The trumpet parts that required this speciality were known by the term clarino, Johann Christoph Denner is generally believed to have invented the clarinet in Germany around the year 1700 by adding a register key to the earlier chalumeau. Over time, additional keywork and airtight pads were added to improve the tone and these days the most popular clarinet is the B♭ clarinet. However, the clarinet in A, just a lower, is commonly used in orchestral music. Since the middle of the 19th century the clarinet has become an essential addition to the orchestra. The clarinet family ranges from the BBB♭ octo-contrabass to the A♭ piccolo clarinet, the clarinet has proved to be an exceptionally flexible instrument, equally at home in the classical repertoire as in concert bands, military bands, marching bands, klezmer, and jazz. The cylindrical bore is primarily responsible for the clarinets distinctive timbre, the tone quality can vary greatly with the musician, the music, the instrument, the mouthpiece, and the reed. The most prominent were the German/Viennese traditions and the French school, the latter was centered on the clarinetists of the Conservatoire de Paris. The proliferation of recorded music has made examples of different styles of clarinet playing available, the modern clarinetist has a diverse palette of acceptable tone qualities to choose from. The A clarinet and B♭ clarinet have nearly the same bore, orchestral players using the A and B♭ instruments in the same concert could use the same mouthpiece for both. The A and the B♭ instruments have nearly identical tonal quality, the tone of the E♭ clarinet is brighter than that of the lower clarinets and can be heard even through loud orchestral or concert band textures. The bass clarinet has a deep, mellow sound, while the alto clarinet is similar in tone to the bass

Saxophone
–
The saxophone is a family of woodwind instruments. Saxophones are usually made of brass and played with a single-reed mouthpiece similar to that of the clarinet, the saxophone family was invented by the Belgian instrument maker Adolphe Sax in 1840. He patented the saxophone on June 28,1846, in two groups of seven instruments each, each series consisted of instruments of various sizes in alternating transposition. The series pitched in B♭ and E♭, designed for bands, have proved extremely popular. The saxophone is used in music, military bands, marching bands. The saxophone was developed in 1846 by Adolphe Sax, a Belgian instrument maker, flautist, born in Dinant and originally based in Brussels, he moved to Paris in 1842 to establish his musical instrument business. Prior to his work on the saxophone, he had several improvements to the bass clarinet by improving its keywork and acoustics. Sax was also a maker of the ophicleide, a large conical brass instrument in the bass register with keys similar to a woodwind instrument. His experience with two instruments allowed him to develop the skills and technologies needed to make the first saxophones. As an outgrowth of his work improving the bass clarinet, Sax began developing an instrument with the projection of a brass instrument and he wanted it to overblow at the octave, unlike the clarinet, which rises in pitch by a twelfth when overblown. An instrument that overblows at the octave has identical fingering for both registers, Sax created an instrument with a single-reed mouthpiece like a clarinet, conical brass body like an ophicleide, and some acoustic properties of both the horn and the clarinet. Having constructed saxophones in several sizes in the early 1840s, Sax applied for, and received, the patent encompassed 14 versions of the fundamental design, split into two categories of seven instruments each, and ranging from sopranino to contrabass. Although the instruments transposed at either F or C have been considered orchestral, the C soprano saxophone was the only instrument to sound at concert pitch. Saxs patent expired in 1866, thereafter, numerous saxophonists and instrument manufacturers implemented their own improvements to the design, the first substantial modification was by a French manufacturer who extended the bell slightly and added an extra key to extend the range downwards by one semitone to B♭. It is suspected that Sax himself may have attempted this modification and this extension is now commonplace in almost all modern designs, along with other minor changes such as added keys for alternate fingerings. Using alternate fingerings allows a player to play faster and more easily, a player may also use alternate fingerings to bend the pitch. Some of the alternate fingerings are good for trilling, scales, a substantial advancement in saxophone keywork was the development of a method by which the left thumb operates both tone holes with a single octave key, which is now universal on modern saxophones. This enables a chromatic scale to be played two octaves simply by playing the diatonic scale combined with alternately raising and lowering this one digit

Brass instrument
–
A brass instrument is a musical instrument that produces sound by sympathetic vibration of air in a tubular resonator in sympathy with the vibration of the players lips. Brass instruments are also called labrosones, literally meaning lip-vibrated instruments, there are several factors involved in producing different pitches on a brass instrument. The view of most scholars is that the brass instrument should be defined by the way the sound is made, as above. Thus one finds brass instruments made of wood, like the alphorn, the cornett, the serpent, as valved instruments are predominant among the brasses today, a more thorough discussion of their workings can be found below. The valves are usually piston valves, but can be rotary valves, slide brass instruments use a slide to change the length of tubing. The main instruments in this category are the family, though valve trombones are occasionally used. The trombone familys ancestor, the sackbut, and the folk instrument bazooka are also in the slide family, there are two other families that have, in general, become functionally obsolete for practical purposes. Instruments of both types, however, are used for period-instrument performances of Baroque or Classical pieces. In more modern compositions, they are used for their intonation or tone color. Natural brass instruments only play notes in the harmonic series. These include the bugle and older variants of the trumpet and horn, the trumpet was a natural brass instrument prior to about 1795, and the horn before about 1820. In the 18th century, makers developed interchangeable crooks of different lengths, natural instruments are still played for period performances and some ceremonial functions, and are occasionally found in more modern scores, such as those by Richard Wagner and Richard Strauss. Keyed or Fingered brass instruments used holes along the body of the instrument and these included the cornett, serpent, ophicleide, keyed bugle and keyed trumpet. They are more difficult to play than valved instruments, Brass instruments may also be characterised by two generalizations about geometry of the bore, that is, the tubing between the mouthpiece and the flaring of the tubing into the bell. Those two generalizations are with regard to the degree of taper or conicity of the bore and the diameter of the bore with respect to its length, cylindrical bore brass instruments are generally perceived as having a brighter, more penetrating tone quality compared to conical bore brass instruments. The trumpet, baritone horn and all trombones are cylindrical bore, in particular, the slide design of the trombone necessitates this. Conical bore brass instruments are those in which tubing of constantly increasing diameter predominates, conical bore instruments are generally perceived as having a more mellow tone quality than the cylindrical bore brass instruments. The British brass band group of instruments fall into this category and this includes the flugelhorn, cornet, tenor horn, horn, euphonium and tuba

Madagascar
–
Madagascar, officially the Republic of Madagascar, and previously known as the Malagasy Republic, is an island country in the Indian Ocean, off the coast of Southeast Africa. The nation comprises the island of Madagascar, and numerous smaller peripheral islands, consequently, Madagascar is a biodiversity hotspot, over 90% of its wildlife is found nowhere else on Earth. The islands diverse ecosystems and unique wildlife are threatened by the encroachment of the growing human population. The first archaeological evidence for human foraging on Madagascar dates to 2000 BC, human settlement of Madagascar occurred between 350 BC and AD550 by Austronesian peoples arriving on outrigger canoes from Borneo. These were joined around AD1000 by Bantu migrants crossing the Mozambique Channel from East Africa, other groups continued to settle on Madagascar over time, each one making lasting contributions to Malagasy cultural life. The Malagasy ethnic group is divided into 18 or more sub-groups of which the largest are the Merina of the central highlands. Until the late 18th century, the island of Madagascar was ruled by an assortment of shifting sociopolitical alliances. Beginning in the early 19th century, most of the island was united and ruled as the Kingdom of Madagascar by a series of Merina nobles, the monarchy collapsed in 1897 when the island was absorbed into the French colonial empire, from which the island gained independence in 1960. The autonomous state of Madagascar has since undergone four major constitutional periods, since 1992, the nation has officially been governed as a constitutional democracy from its capital at Antananarivo. However, in an uprising in 2009, president Marc Ravalomanana was made to resign. Constitutional governance was restored in January 2014, when Hery Rajaonarimampianina was named president following a 2013 election deemed fair, Madagascar is a member of the United Nations, the Organisation Internationale de la Francophonie and the Southern African Development Community. Madagascar belongs to the group of least developed countries, according to the United Nations, Malagasy and French are both official languages of the state. The majority of the population adheres to traditional beliefs, Christianity, ecotourism and agriculture, paired with greater investments in education, health, and private enterprise, are key elements of Madagascars development strategy. As of 2017, the economy has been weakened by the 2009-2013 political crisis, in the Malagasy language, the island of Madagascar is called Madagasikara and its people are referred to as Malagasy. The islands appellation Madagascar is not of origin, but rather was popularized in the Middle Ages by Europeans. On St. Laurences Day in 1500, Portuguese explorer Diogo Dias landed on the island, polos name was preferred and popularized on Renaissance maps. At 592,800 square kilometres, Madagascar is the worlds 47th largest country, the country lies mostly between latitudes 12°S and 26°S, and longitudes 43°E and 51°E. Neighboring islands include the French territory of Réunion and the country of Mauritius to the east, as well as the state of Comoros, the nearest mainland state is Mozambique, located to the west

Adolphe Sax
–
Antoine-Joseph Adolphe Sax was a Belgian inventor and musician who invented the saxophone in 1846. He played the flute and clarinet, and his inventions are the saxotromba, saxhorn. Antoine-Joseph Sax was born on 6 November 1814, in Dinant, Belgium, to Charles-Joseph Sax, while his first name was Antoine, he was referred to as Adolphe from childhood. His father and mother were instrument designers themselves, who made changes to the design of the horn. Adolphe began to make his own instruments at an early age and he subsequently studied performance on those two instruments as well as voice at the Royal Conservatory of Brussels. According to the biography of Adolphe Sax published on the city of Dinants website and his neighbors called him little Sax, the ghost. After leaving the Royal Conservatory of Brussels, Sax began to experiment with new instrument designs, adolphes first important invention was an improvement of the bass clarinet design, which he patented at the age of 24. Sax relocated permanently to Paris in 1841 and began working on a new set of instruments exhibited there in 1844. These were valved bugles, and although he had not invented the instrument itself, his examples were more successful than those of his rivals. They came in seven different sizes, and paved the path to the creation of the flugelhorn. Today, saxhorns are sometimes used in bands and orchestras. The saxhorn also laid the groundwork for the modern euphonium, Sax also developed the saxotromba family, valved brass instruments with narrower bore than the saxhorns, in 1845, though they survived only briefly. The saxhorn valves were accepted as state-of-the-art and are largely unchanged today, the advances made by Adolphe Sax were soon followed by the British brass band movement which exclusively adopted the saxhorn range. The Jedforest Instrumental Band formed in 1854 and The Hawick Saxhorn Band formed in 1855, within the Scottish Borders, the period around 1840 saw Sax inventing the clarinette-bourdon, an early unsuccessful design of contrabass clarinet. Around this time he developed the instrument for which he is best known. The saxophone was invented for use in orchestras and concert bands. Composer Hector Berlioz wrote approvingly of the new instrument in 1842, by 1846 Sax had designed, on paper, a full range of saxophones. Although they never became standard orchestral instruments, the made his reputation and secured him a job

Classical music
–
Classical music is art music produced or rooted in the traditions of Western music, including both liturgical and secular music. The central norms of this tradition became codified between 1550 and 1900, which is known as the common-practice period, Western staff notation is used by composers to indicate to the performer the pitches, tempo, meter and rhythms for a piece of music. This can leave less room for such as improvisation and ad libitum ornamentation. The term classical music did not appear until the early 19th century, the earliest reference to classical music recorded by the Oxford English Dictionary is from about 1836. This score typically determines details of rhythm, pitch, and, the written quality of the music has enabled a high level of complexity within them, J. S. The use of written notation also preserves a record of the works, Musical notation enables 2000s-era performers to sing a choral work from the 1300s Renaissance era or a 1700s Baroque concerto with many of the features of the music being reproduced. That said, the score does not provide complete and exact instructions on how to perform a historical work, even if the tempo is written with an Italian instruction, we do not know exactly how fast the piece should be played. Bach was particularly noted for his complex improvisations, during the Classical era, the composer-performer Mozart was noted for his ability to improvise melodies in different styles. During the Classical era, some virtuoso soloists would improvise the cadenza sections of a concerto, during the Romantic era, Beethoven would improvise at the piano. The instruments currently used in most classical music were largely invented before the mid-19th century and they consist of the instruments found in an orchestra or in a concert band, together with several other solo instruments. The symphony orchestra is the most widely known medium for music and includes members of the string, woodwind, brass. The concert band consists of members of the woodwind, brass and it generally has a larger variety and number of woodwind and brass instruments than the orchestra but does not have a string section. However, many bands use a double bass. Many of the used to perform medieval music still exist. Medieval instruments included the flute, the recorder and plucked string instruments like the lute. As well, early versions of the organ, fiddle, Medieval instruments in Europe had most commonly been used singly, often self accompanied with a drone note, or occasionally in parts. From at least as early as the 13th century through the 15th century there was a division of instruments into haut, during the earlier medieval period, the vocal music from the liturgical genre, predominantly Gregorian chant, was monophonic, using a single, unaccompanied vocal melody line. Polyphonic vocal genres, which used multiple independent vocal melodies, began to develop during the medieval era, becoming prevalent by the later 13th

Jazz
–
Jazz is a music genre that originated amongst African Americans in New Orleans, United States, in the late 19th and early 20th centuries, and developed from roots in Blues and Ragtime. Since the 1920s jazz age, jazz has become recognized as a form of musical expression. Jazz is characterized by swing and blue notes, call and response vocals, polyrhythms, Jazz has roots in West African cultural and musical expression, and in African-American music traditions including blues and ragtime, as well as European military band music. Although the foundation of jazz is deeply rooted within the Black experience of the United States, different cultures have contributed their own experience, intellectuals around the world have hailed jazz as one of Americas original art forms. As jazz spread around the world, it drew on different national, regional, and local musical cultures, New Orleans jazz began in the early 1910s, combining earlier brass-band marches, French quadrilles, biguine, ragtime and blues with collective polyphonic improvisation. In the 1930s, heavily arranged dance-oriented swing big bands, Kansas City jazz, bebop emerged in the 1940s, shifting jazz from danceable popular music toward a more challenging musicians music which was played at faster tempos and used more chord-based improvisation. Cool jazz developed in the end of the 1940s, introducing calmer, smoother sounds and long, modal jazz developed in the late 1950s, using the mode, or musical scale, as the basis of musical structure and improvisation. Jazz-rock fusion appeared in the late 1960s and early 1970s, combining jazz improvisation with rock rhythms, electric instruments. In the early 1980s, a form of jazz fusion called smooth jazz became successful. Other styles and genres abound in the 2000s, such as Latin, the question of the origin of the word jazz has resulted in considerable research, and its history is well documented. It is believed to be related to jasm, a term dating back to 1860 meaning pep. The use of the word in a context was documented as early as 1915 in the Chicago Daily Tribune. Its first documented use in a context in New Orleans was in a November 14,1916 Times-Picayune article about jas bands. In an interview with NPR, musician Eubie Blake offered his recollections of the slang connotations of the term, saying, When Broadway picked it up. That was dirty, and if you knew what it was, the American Dialect Society named it the Word of the Twentieth Century. Jazz has proved to be difficult to define, since it encompasses such a wide range of music spanning a period of over 100 years. Attempts have been made to define jazz from the perspective of other musical traditions, in the opinion of Robert Christgau, most of us would say that inventing meaning while letting loose is the essence and promise of jazz. As Duke Ellington, one of jazzs most famous figures, said, although jazz is considered highly difficult to define, at least in part because it contains so many varied subgenres, improvisation is consistently regarded as being one of its key elements

Turbulence
–
Turbulence or turbulent flow is a flow regime in fluid dynamics characterized by chaotic changes in pressure and flow velocity. It is in contrast to a flow regime, which occurs when a fluid flows in parallel layers. Turbulence is caused by kinetic energy in parts of a fluid flow. For this reason turbulence is easier to create in low viscosity fluids, in general terms, in turbulent flow, unsteady vortices appear of many sizes which interact with each other, consequently drag due to friction effects increases. This would increase the energy needed to pump fluid through a pipe, however this effect can also be exploited by such as aerodynamic spoilers on aircraft, which deliberately spoil the laminar flow to increase drag and reduce lift. The onset of turbulence can be predicted by a constant called the Reynolds number. However, turbulence has long resisted detailed physical analysis, and the interactions within turbulence creates a complex situation. Richard Feynman has described turbulence as the most important unsolved problem of classical physics, smoke rising from a cigarette is mostly turbulent flow. However, for the first few centimeters the flow is laminar, the smoke plume becomes turbulent as its Reynolds number increases, due to its flow velocity and characteristic length increasing. If the golf ball were smooth, the boundary layer flow over the front of the sphere would be laminar at typical conditions. However, the layer would separate early, as the pressure gradient switched from favorable to unfavorable. To prevent this happening, the surface is dimpled to perturb the boundary layer. This results in higher skin friction, but moves the point of boundary layer separation further along, resulting in form drag. The flow conditions in industrial equipment and machines. The external flow over all kind of such as cars, airplanes, ships. The motions of matter in stellar atmospheres, a jet exhausting from a nozzle into a quiescent fluid. As the flow emerges into this external fluid, shear layers originating at the lips of the nozzle are created and these layers separate the fast moving jet from the external fluid, and at a certain critical Reynolds number they become unstable and break down to turbulence. Biologically generated turbulence resulting from swimming animals affects ocean mixing, snow fences work by inducing turbulence in the wind, forcing it to drop much of its snow load near the fence

Wikisource
–
Wikisource is an online digital library of free content textual sources on a wiki, operated by the Wikimedia Foundation. Wikisource is the name of the project as a whole and the name for each instance of that project, the projects aims are to host all forms of free text, in many languages, and translations. Originally conceived as an archive to store useful or important historical texts, the project officially began in November 24,2003 under the name Project Sourceberg. The name Wikisource was adopted later that year and it received its own domain name seven months later, the project has come under criticism for lack of reliability but it is also cited by organisations such as the National Archives and Records Administration. The project holds works that are either in the domain or freely licensed, professionally published works or historical source documents, not vanity products. Verification was initially made offline, or by trusting the reliability of digital libraries. Now works are supported by online scans via the ProofreadPage extension, some individual Wikisources, each representing a specific language, now only allow works backed up with scans. While the bulk of its collection are texts, Wikisource as a whole hosts other media, some Wikisources allow user-generated annotations, subject to the specific policies of the Wikisource in question. Wikisources early history included several changes of name and location, the original concept for Wikisource was as storage for useful or important historical texts. These texts were intended to support Wikipedia articles, by providing evidence and original source texts. The collection was focused on important historical and cultural material. The project was originally called Project Sourceberg during its planning stages, in 2001, there was a dispute on Wikipedia regarding the addition of primary source material, leading to edit wars over their inclusion or deletion. Project Sourceberg was suggested as a solution to this, perhaps Project Sourceberg can mainly work as an interface for easily linking from Wikipedia to a Project Gutenberg file, and as an interface for people to easily submit new work to PG. Wed want to complement Project Gutenberg--how, exactly, and Jimmy Wales adding like Larry, Im interested that we think it over to see what we can add to Project Gutenberg. It seems unlikely that primary sources should in general be editable by anyone -- I mean, Shakespeare is Shakespeare, unlike our commentary on his work, the project began its activity at ps. wikipedia. org. The contributors understood the PS subdomain to mean either primary sources or Project Sourceberg, however, this resulted in Project Sourceberg occupying the subdomain of the Pashto Wikipedia. A vote on the name changed it to Wikisource on December 6,2003. Despite the change in name, the project did not move to its permanent URL until July 23,2004, since Wikisource was initially called Project Sourceberg, its first logo was a picture of an iceberg

Oxford English Dictionary
–
The Oxford English Dictionary is a descriptive dictionary of the English language, published by the Oxford University Press. The second edition came to 21,728 pages in 20 volumes, in 1895, the title The Oxford English Dictionary was first used unofficially on the covers of the series, and in 1928 the full dictionary was republished in ten bound volumes. In 1933, the title The Oxford English Dictionary fully replaced the name in all occurrences in its reprinting as twelve volumes with a one-volume supplement. More supplements came over the years until 1989, when the edition was published. Since 2000, an edition of the dictionary has been underway. The first electronic version of the dictionary was available in 1988. The online version has been available since 2000, and as of April 2014 was receiving two million hits per month. The third edition of the dictionary will probably appear in electronic form, Nigel Portwood, chief executive of Oxford University Press. As a historical dictionary, the Oxford English Dictionary explains words by showing their development rather than merely their present-day usages, therefore, it shows definitions in the order that the sense of the word began being used, including word meanings which are no longer used. The format of the OEDs entries has influenced numerous other historical lexicography projects and this influenced later volumes of this and other lexicographical works. As of 30 November 2005, the Oxford English Dictionary contained approximately 301,100 main entries, the dictionarys latest, complete print edition was printed in 20 volumes, comprising 291,500 entries in 21,730 pages. The longest entry in the OED2 was for the verb set, as entries began to be revised for the OED3 in sequence starting from M, the longest entry became make in 2000, then put in 2007, then run in 2011. Despite its impressive size, the OED is neither the worlds largest nor the earliest exhaustive dictionary of a language, the Dutch dictionary Woordenboek der Nederlandsche Taal is the worlds largest dictionary, has similar aims to the OED and took twice as long to complete. Another earlier large dictionary is the Grimm brothers dictionary of the German language, begun in 1838, the official dictionary of Spanish is the Diccionario de la lengua española, and its first edition was published in 1780. The Kangxi dictionary of Chinese was published in 1716, trench suggested that a new, truly comprehensive dictionary was needed. On 7 January 1858, the Society formally adopted the idea of a new dictionary. Volunteer readers would be assigned particular books, copying passages illustrating word usage onto quotation slips, later the same year, the Society agreed to the project in principle, with the title A New English Dictionary on Historical Principles. He withdrew and Herbert Coleridge became the first editor, on 12 May 1860, Coleridges dictionary plan was published and research was started

Reed (mouthpiece)
–
A reed is a thin strip of material which vibrates to produce a sound on a musical instrument. The reeds of most woodwind instruments are made from Arundo donax or synthetic material, musical instruments may be classified according to the type and number of reeds used. The earliest types of single-reed instruments used idioglottal reeds, where the reed is a tongue cut. Much later, single-reed instruments started using heteroglottal reeds, where a reed is cut and separated from the tube of cane, by contrast, in a an uncapped double reed instrument, there is no mouthpiece, the two parts of the reed vibrate against one another. Single reeds are used on the mouthpieces of clarinets and saxophones, the back of the reed is flat and is placed against the mouthpiece, the rounded top side tapers to a thin tip. These reeds are roughly rectangular in shape except for the thin vibrating tip, all single reeds are shaped similarly but vary in size to fit each instruments mouthpiece. Reeds designed for the instrument may look identical to each other. Hardness is generally measured on a scale of 1 through 5 from softest to hardest and this is not a standardized scale and reed strengths vary by manufacturer. The thickness of the tip and heel and the profile in between affect the sound and playability, cane of different grades, even if cut with the same profile, will also respond differently. This is due to the natural differences in the density of the cane fibers. The cane used to make reeds for saxophone, clarinet, once the cane is cut, it must lay out and dry in direct sunlight for about a month. The cane is rotated regularly to ensure proper and complete drying, once dry, they are taken to be stored in a warehouse. As the cane is needed, it is pulled from the warehouse, once at the factory, the cane is taken to the cutting department where it is cut into tubes. The tubes are graded by diameter and wall density, the tubes are then cut into splits which are transformed into reed blanks. The blanks are tapered and profiled using blades or CNC machines into reeds, after the reeds are completed, they are taken to a machine that grades them for strength. Double reeds are used on the oboe, oboe damore, English horn, bass oboe, Heckelphone, bassoon, contrabassoon, sarrusophone, shawm, bagpipes, nadaswaram and they are typically not used in conjunction with a mouthpiece, rather the two reeds vibrate against each other. Reed strengths are graded from hard to soft, the making of double reeds begins in the same way as how single reeds are made. The cane is collected from Arundo donax, dried, processed, similar to single reed production, the cane is separated into various diameters. The most common diameters for American-style oboe reeds are as follows,9. 5–10 mm, 10–10.5 mm, many American oboists prefer a specific diameter at one time of the year and a different diameter at other times, depending on the season and the weather

Embouchure
–
The embouchure is the use of facial muscles and the shaping of the lips to the mouthpiece of woodwind instruments or the mouthpiece of the brass instruments. The word is of French origin and is related to the root bouche, the proper embouchure allows the instrumentalist to play the instrument at its full range with a full, clear tone and without strain or damage to ones muscles. While performing on an instrument, the sound is produced by the player buzzing his or her lips into a mouthpiece. Pitches are changed in part through altering the amount of muscular contraction in the lip formation, the performers use of the air, tightening of cheek and jaw muscles, as well as tongue manipulation can affect how the embouchure works. Even today, many brass pedagogues take an approach to teaching how a brass players embouchure should function. Many of these authors also disagree with each other regarding which technique is correct, research suggests efficient brass embouchures depend on the player using the method that suits that players particular anatomy. In 1962, Philip Farkas hypothesized that the air stream traveling through the lip aperture should be directed straight down the shank of the mouthpiece and he believed that it would be illogical to violently deflect the air stream downward at the point of where the air moves past the lips. In this text, Farkas also recommends that the lower jaw be protruded so that the upper and lower teeth are aligned, in 1970, Farkas published a second text which contradicted his earlier writing. Out of 40 subjects, Farkas showed that 39 subjects directed the air downward to varying degrees, the lower jaw position seen in these photographs show more variation from his earlier text as well. This supports what was written by trombonist and brass pedagogue Donald S. Reinhardt in 1942. According to this text, players who place the mouthpiece higher on the lips, so that more upper lip is inside the mouthpiece. Performers who place the lower, so that more lower lip is inside the mouthpiece. In order for the performer to be successful, the air stream direction, lloyd Leno confirmed the existence of both upstream and downstream embouchures. More controversial was Reinhardts description and recommendations regarding a phenomenon he termed a pivot, whether the player uses one general pivot direction or the other, and the degree to which the motion is performed, depends on the performers anatomical features and stage of development. The placement of the mouthpiece upon the lips doesnt change, but rather the relationship of the rim, later research supports Reinhardts claim that this motion exists and might be advisable for brass performers to adopt. Froelich noted that the symphonic trombonists used the least amount of direct and shear forces and recommends this model be followed. Other research notes that virtually all brass performers rely upon the upward and downward embouchure motion, other authors and pedagogues remain skeptical about the necessity of this motion, but scientific evidence supporting this view has not been sufficiently developed at this time to support this view. Some noted brass pedagogues prefer to instruct the use of the embouchure from an analytical point of view
