Flute


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. Flutes produce 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.
Paleolithic flutes with hand-bored holes are the earliest known identifiable musical instruments. 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, indicating a developed musical tradition from the earliest period of modern human presence in Europe. While the oldest flutes currently known were found in Europe, Asia also has a long history with the instrument. A playable bone flute discovered in China is dated to about 9,000 years ago. The Americas also had an ancient flute culture, with instruments found in Caral, Peru, dating back 5,000 years and in Labrador dating back about 7,500 years.
The bamboo flute has a long history, especially in China and India. Flutes have been discovered in historical records and artworks starting in the Zhou dynasty. The oldest written sources reveal the Chinese were using the kuan and xīao in the 12th–11th centuries BC, followed by the chi in the 9th century BC and the yüeh in the 8th century BC. Of these, the bamboo chi is the oldest documented transverse flute.
Musicologist Curt Sachs called the cross flute "the outstanding wind instrument of ancient India", and said that religious artwork depicting "celestial music" instruments was linked to music with an "aristocratic character". The Indian bamboo cross flute, Bansuri, was sacred to Krishna, who is depicted with the instrument in Hindu art. In India, the cross flute appeared in reliefs from the 1st century AD at Sanchi and Amaravati from the 2nd–4th centuries AD.
According to historian Alexander Buchner, there were flutes in Europe in prehistoric times, but they disappeared from the continent until flutes arrived from Asia by way of "North Africa, Hungary, and Bohemia". The end-blown flute began to be seen in illustration in the 11th century. Transverse flutes entered Europe through Byzantium and were depicted in Greek art about 800 AD. The transverse flute had spread into Europe by way of Germany, and was known as the German flute.

Etymology and terminology

The word flute first appeared in the English language during the Middle English period, as floute, flowte, or flote, possibly from Old French flaute and Old Provençal flaüt, or possibly from Old French fleüte, flaüte, flahute via Middle High German floite or Dutch fluit. The English verb flout has the same linguistic root, and the modern Dutch verb fluiten still shares the two meanings. Attempts to trace the word back to the Latin flare have been called "phonologically impossible" or "inadmissable". The first known use of the word flute was in the 14th century. According to the Oxford English Dictionary, this was in Geoffrey Chaucer's The Hous of Fame,.
A musician who plays any instrument in the flute family can be called a flutist, flautist, or flute player. Flutist dates back to at least 1603, the earliest quotation cited by the Oxford English Dictionary. Flautist was used in 1860 by Nathaniel Hawthorne in The Marble Faun, after being adopted during the 18th century from Italy, like many musical terms in England since the Italian Renaissance. Other English terms, now virtually obsolete, are fluter and flutenist.

History

A fragment of a juvenile cave bear's femur, with two to four holes, was found at Divje Babe in Slovenia and dated to about 43,000 years ago. It may be the oldest flute discovered, but this has been disputed. In 2008, a flute dated to at least 35,000 years ago was discovered in Hohle Fels cave near Ulm, Germany. It is a five-holed flute with a V-shaped mouthpiece and was made from a vulture wing bone. The discovery was published in the journal Nature, in August 2009. This was the oldest confirmed musical instrument ever found, until a redating of flutes found in Geißenklösterle cave revealed them to be older, at 42,000 to 43,000 years.
The Hohle Fels flute is one of several found in the Hohle Fels cavern next to the Venus of Hohle Fels and a short distance from the oldest known human carving. On announcing the discovery, scientists suggested that the "finds demonstrate the presence of a well-established musical tradition at the time when modern humans colonized Europe". Scientists have also suggested that this flute's discovery may help to explain "the probable behavioural and cognitive gulf between" Neanderthals and early modern human.
An 18.7 cm flute with three holes, made from a mammoth tusk and dated to 30,000–37,000 years ago, was found in 2004 in the Geißenklösterle cave near Ulm, in the southern German Swabian Alb. Two flutes made from swan bones were excavated a decade earlier from the same cave and dated to about 36,000 years ago.
A playable 9,000-year-old Chinese Gudi was excavated from a tomb in Jiahu along with 29 similar specimens. They were made from the wing bones of red-crowned cranes and each has five to eight holes.
The earliest extant Chinese transverse flute is a chi flute discovered in the Tomb of Marquis Yi of Zeng at the Suizhou site, Hubei province, China, dating from 433 BC, during the later Zhou dynasty. It is fashioned of lacquered bamboo with closed ends and has five stops on the flute's side instead of the top. Shi Jing, traditionally said to have been compiled and edited by Confucius, mentions chi flutes.
The earliest written reference to a flute is from a Sumerian-language cuneiform tablet dated to c. 2600–2700 BC.
Flutes are mentioned in a recently translated tablet of the Epic of Gilgamesh, an epic poem whose development spanned the period from about 2100–600 BC. A set of cuneiform tablets knows as the "musical texts" provide precise tuning instructions for seven scales of a stringed instrument. One of those scales is named "embūbum", which is an Akkadian word for "flute".
The Bible, in Genesis 4:21, cites Jubal as being the "father of all those who play the ugab and the kinnor". The former Hebrew term is believed by some to refer to a wind instrument, or wind instruments in general, the latter to a stringed instrument, or stringed instruments in general. As such, Jubal is regarded in the Judeo-Christian tradition as the inventor of the flute. In other sections of the Bible the flute is referred to as "chalil", from the root word for "hollow". Archeological digs in the Holy Land have discovered flutes from the Bronze Age and the Iron Age, the latter era "witness the creation of the Israelite kingdom and its separation into the two kingdoms of Israel and Judea."
Some early flutes were made out of tibias. The flute has also always been an essential part of Indian culture, and the cross flute believed by several accounts to originate in India as Indian literature from 1500 BC has made vague references to the cross flute.

Acoustics

A flute produces sound when a stream of air directed across a hole in the instrument creates a vibration of air at the hole. The airstream creates a Bernoulli or siphon. This excites the air contained in the resonant cavity within the flute. The flutist changes the pitch of the sound produced by opening and closing holes in the body of the instrument, thus changing the effective length of the resonator and its corresponding resonant frequency. By varying the air pressure, a flutist can also change the pitch by causing the air in the flute to resonate at a harmonic rather than the fundamental frequency without opening or closing any of the holes.
Head joint geometry appears particularly critical to acoustic performance and tone, but there is no clear consensus among manufacturers on a particular shape. Acoustic impedance of the embouchure hole appears the most critical parameter. Critical variables affecting this acoustic impedance include: the length of the chimney, chimney diameter, and radii or curvature of the ends of the chimney and any designed restriction in the "throat" of the instrument, such as that in the Japanese Nohkan flute.
A study in which professional flutists were blindfolded could find no significant differences between flutes made from a variety of metals. In two different sets of blind listening, no flute was correctly identified in a first listening, and in a second, only the silver flute was identified. The study concluded that there was "no evidence that the wall material has any appreciable effect on the sound color or dynamic range".

Materials

Historically, flutes were most commonly made of reed, bamboo, wood, or other organic materials. They were also made of glass, bone, and nephrite. Most modern flutes are made of metal, primarily silver and nickel. Silver is less common than silver alloys. Other materials used for flutes include gold, platinum, grenadilla and copper.

Types

In its most basic form, a flute is an open tube which is blown into. After focused study and training, players use controlled air-direction to create an airstream in which the air is aimed downward into the tone hole of the flute's headjoint. There are several broad classes of flutes. With most flutes, the musician blows directly across the edge of the mouthpiece, with 1/4 of their bottom lip covering the embouchure hole. However, some flutes, such as the whistle, gemshorn, flageolet, recorder, tin whistle, tonette, fujara, and ocarina have a duct that directs the air onto the edge. These are known as fipple flutes. The fipple gives the instrument a distinct timbre which is different from non-fipple flutes and makes the instrument easier to play, but takes a degree of control away from the musician.
Another division is between side-blown flutes, such as the Western concert flute, piccolo, fife, dizi and bansuri; and end-blown flutes, such as the ney, xiao, kaval, danso, shakuhachi, Anasazi flute and quena. The player of a side-blown flute uses a hole on the side of the tube to produce a tone, instead of blowing on an end of the tube. End-blown flutes should not be confused with fipple flutes such as the recorder, which are also played vertically but have an internal duct to direct the air flow across the edge of the tone hole.
Flutes may be open at one or both ends. The ocarina, xun, pan pipes, police whistle, and bosun's whistle are closed-ended. Open-ended flutes such as the concert flute and the recorder have more harmonics, and thus more flexibility for the player, and brighter timbres. An organ pipe may be either open or closed, depending on the sound desired.
Flutes may have any number of pipes or tubes, though one is the most common number. Flutes with multiple resonators may be played one resonator at a time or more than one at a time.
Flutes can be played with several different air sources. Conventional flutes are blown with the mouth, although some cultures use nose flutes. The flue pipes of organs, which are acoustically similar to duct flutes, are blown by bellows or fans.
