supports: A birbyn is a Lithuanian aerophone that can be either single or double-reeded and may or may not have a mouthpiece. "Birbyn" can be made of a variety of materials: wood, bark, horn, straw, goose feather, etc. The earliest and simplest examples were used by children as playtoys and by shepherds as a tool to control the herd. In the 19th century, influenced by classical instruments and especially the clarinet, the "birbyn" evolved into a serious musical instrument used in ensembles. Modern "birbyns" are made of wood with bells of horn and usually have ten tone holes. They are divided by pitch range into three categories: soprano, tenor, and contrabass. Bark is the outermost layers of stems and roots of woody plants. Plants with bark include trees, woody vines, and shrubs. Bark refers to all the tissues outside of the vascular cambium and is a nontechnical term. It overlays the wood and consists of the inner bark and the outer bark. The inner bark, which in older stems is living tissue, includes the innermost area of the periderm. The outer bark in older stems includes the dead tissue on the surface of the stems, along with parts of the innermost periderm and all the tissues on the outer side of the periderm. The outer bark on trees which lies external to the last formed periderm is also called the rhytidome. The dili tuiduk,   (also dilli düdük, dilli tuyduk , dili tüidük, dilli tüidük ) is a Turkmen woodwind instrument. It is a clarinet-like, single-reed instrument used mainly in Turkmen folk music. Dilli-tuyduk These come in two kinds. In one, the reed end of the instrument is closed and in the other it is open. A reed is cut in the upper part of the pipe and 3 or 4 finger holes are cut on the upper part, at intervals of some 5-6mm. Its range is a 6thor 7th, from about fa in the first octave to re or mi in the second. Some sounds have to be made by overblowing or by partly exposing the finger holes. The dilli-tuyduk makes a penetrating sound and is used to play the tunes of Turkmen folk songs. Versions of song tunes in the form of ditties for the dilli-tuyduk start in a long drawn-out sound going into the main melody. The zurna ( also called surnay , birbyn , lettish horn , surla , sornai , dili tuiduk , zournas , or zurma ) , is a wind instrument played in central Eurasia , ranging from the Balkans to Central Asia . It is usually accompanied by a davul ( bass drum ) in Anatolian folk music . 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. The davul or tupan is a large double-headed drum that is played with mallets. It has many names depending on the country and region. The drum is a member of the percussion group of musical instruments. In the Hornbostel-Sachs classification system, it is a membranophone. Drums consist of at least one membrane, called a drumhead or drum skin, that is stretched over a shell and struck, either directly with the player's hands, or with a drum stick, to produce sound. There is usually a "resonance head" on the underside of the drum, typically tuned to a slightly lower pitch than the top drumhead. Other techniques have been used to cause drums to make sound, such as the thumb roll. Drums are the world's oldest and most ubiquitous musical instruments, and the basic design has remained virtually unchanged for thousands of years. A tone hole is an opening in the body of a wind instrument which, when alternately closed and opened, changes the pitch of the sound produced. Tone holes may serve specific purposes, such as a trill hole or register hole. A tone hole is, "in wind instruments[,] a hole that may be stopped by the finger, or a key, to change the pitch of the tone produced." The clarinet is a musical-instrument family belonging to the group known as the woodwind instruments. It has a single-reed mouthpiece, a straight cylindrical tube with an almost cylindrical bore, and a flared bell. A person who plays a clarinet is called a "clarinetist" (sometimes spelled "clarinettist"). Woodwind instruments are a family of musical instruments within the more general category of wind instruments. There are two main types of woodwind instruments: flutes and reed instruments (otherwise called reed pipes). What differentiates these instruments from other wind instruments is the way in which they produce their sound. Examples are a saxophone, a bassoon and a piccolo. A resonator is a device or system that exhibits resonance or resonant behavior, that is, it naturally oscillates at some frequencies, called its resonant frequencies, with greater amplitude than at others. The oscillations in a resonator can be either electromagnetic or mechanical (including acoustic). Resonators are used to either generate waves of specific frequencies or to select specific frequencies from a signal. Musical instruments use acoustic resonators that produce sound waves of specific tones. Another example is quartz crystals used in electronic devices such as radio transmitters and quartz watches to produce oscillations of very precise frequency. Lithuania (UK and US: ), officially the Republic of Lithuania, is a country in Northern Europe. One of the three Baltic states, it is situated along the southeastern shore of the Baltic Sea, to the east of Sweden and Denmark. It is bordered by Latvia to the north, Belarus to the east and south, Poland to the south, and Kaliningrad Oblast (a Russian exclave) to the southwest. Lithuania has an estimated population of 2.9 million people , and its capital and largest city is Vilnius. Lithuanians are a Baltic people. The official language, Lithuanian, along with Latvian, is one of only two living languages in the Baltic branch of the Indo-European language family. A single-reed instrument is a woodwind instrument that uses only one reed to produce sound. The very earliest single-reed instruments were documented in ancient Egypt, as well as the Middle East, Greece, and the Roman Empire. The earliest types of single-reed instruments used idioglottal reeds, where the vibrating reed is a tongue cut and shaped on the tube of cane. Much later, single-reed instruments started using heteroglottal reeds, where a reed is cut and separated from the tube of cane and attached to a mouthpiece of some sort. By contrast, in a double reed instrument (such as the oboe and bassoon), there is no mouthpiece; the two parts of the reed vibrate against one another. Reeds are traditionally made of cane and produce sound when air is blown across or through them.
  Most single-reed instruments are descended from single-reed idioglot instruments called 'memet', found in Egypt as early as 2700 BCE. Due to their fragility, no instruments from antiquity were preserved but iconographic evidence is prevalent. During the Old Kingdom in Egypt (27782723 BCE), memets were depicted on the reliefs of seven tombs at Saqqarra, six tombs at Giza, and the pyramids of Queen Khentkaus. Most memets were double-clarinets, where two reed tubes were tied or glued together to form one instrument. Multiple pipes were used to reinforce sound or generate a strong beat-tone with slight variations in tuning among the pipes. One of the tubes usually functioned as a drone, but the design of these simple instruments varied endlessly. The entire reed entered the mouth, meaning that the player could not easily articulate so melodies were defined by quick movement of the fingers on the tone holes. These types of double-clarinets are still prevalent today, but also developed into simplified single-clarinets and hornpipes. Modern-day idioglots found in Egypt include the arghul and the zummara. An aerophone is any musical instrument that produces sound primarily by causing a body of air to vibrate, without the use of strings or membranes, and without the vibration of the instrument itself adding considerably to the sound. Aerophones categorically comprise "the largest and most complex group of instruments in the Americas".
