Moldova the Republic of Moldova, is a landlocked country in Eastern Europe, bordered by Romania to the west and Ukraine to the north and south. The capital city is Chișinău. Most of the Moldovan territory was a part of the Principality of Moldavia from the 14th century until 1812, when it was ceded to the Russian Empire by the Ottoman Empire and became known as Bessarabia. In 1856, southern Bessarabia was returned to Moldavia, which three years united with Wallachia to form Romania, but Russian rule was restored over the whole of the region in 1878. During the 1917 Russian Revolution, Bessarabia became autonomous and the independent Moldavian Democratic Republic until it was integrated into Romania in 1918 following a vote of its assembly; the decision was disputed by Soviet Russia, which in 1924 allowed the establishment, within the Ukrainian SSR, of a Moldavian autonomous republic on partial Moldovan-inhabited territories to the east of the Dniester. In 1940, as a consequence of the Molotov–Ribbentrop Pact, Romania was compelled to cede Bessarabia to the Soviet Union, leading to the creation of the Moldavian Soviet Socialist Republic, which included the greater part of Bessarabia and the westernmost strip of the former MASSR.
On 27 August 1991, as the dissolution of the Soviet Union was under way, the Moldavian SSR declared independence and took the name Moldova. The Constitution of Moldova was adopted in 1994; the strip of the Moldovan territory on the east bank of the Dniester river has been under the de facto control of the breakaway government of Transnistria since 1990. Due to a decrease in industrial and agricultural output following the dissolution of the Soviet Union, the service sector has grown to dominate Moldova's economy and is over 60% of the nation's GDP, its economy is the poorest in Europe in per capita terms and has the lowest Human Development Index in the continent. Moldova is the least visited country in Europe by tourists with only 11,000 annually recorded visitors from abroad. Moldova is a parliamentary republic with a president as head of state and a prime minister as head of government, it is a member state of the United Nations, the Council of Europe, the World Trade Organization, the Organization for Security and Cooperation in Europe, the GUAM Organization for Democracy and Economic Development, the Commonwealth of Independent States and the Organization of the Black Sea Economic Cooperation and aspires to join the European Union.
The name "Moldova" is derived from the Moldova River. The origin of the name of the river remains unclear. According to a legend recounted by Moldavian chroniclers Dimitrie Cantemir and Grigore Ureche, Prince Dragoș named the river after hunting an aurochs: following the chase, the prince's exhausted hound Molda drowned in the river; the dog's name, given to the river, extended to the Principality. For a short time in the 1990s, at the founding of the Commonwealth of Independent States, the name of the current Republic of Moldova was spelled "Moldavia". After the dissolution of the Soviet Union, the country began to use Moldova; the name Republic of Moldova is designated by the United Nations. The prehistory of Moldova covers the period from the Upper Paleolithic which begins with the presence of Homo sapiens in the area of Southeastern Europe some 44,000 years ago and extends into the appearance of the first written records in Classical Antiquity in Greece. In 2010 N. K. Anisjutkin discovered Oldowan flint tools at Bayraki.
During the Neolithic stone-age era, Moldova's territory stood at the centre of the large Cucuteni–Trypillia culture that stretched east beyond the Dniester River in Ukraine and west up to and beyond the Carpathian Mountains in Romania. The people of this civilization, which lasted from 5500 to 2750 BC, practised agriculture, raised livestock and made intricately-designed pottery. In antiquity, Moldova's territory was inhabited by Dacian tribes. Between the 1st and 7th centuries AD, the south was intermittently under the Roman, Byzantine Empires. Due to its strategic location on a route between Asia and Europe, the territory of modern Moldova was invaded many times in late antiquity and the early Middle Ages, including by Goths, Avars, Magyars, Cumans and Tatars. Friar William of Rubruck, who visited the court of the Great Khan in the 1250s, listed "the Blac", or Vlachs, among the peoples who paid tribute to the Mongols, but the Vlachs' territory is uncertain. Rubruck described "Blakia" as "Assan's territory" south of the Lower Danube, showing that he identified it with the northern regions of the Second Bulgarian Empire.
The Bolohoveni, a Vlach population, is mentioned by the Hypatian Chronicle in the 13th century. The chronicle shows that this land is bordered on the principalities of Halych and Kiev. Archaeological research identified the location of 13th-century fortified settlements in this region. Alexandru V. Boldur identified Voscodavie, Voloscovti, Volcovti and their other towns and villages between the middle course of the rivers Nistru/Dniester and Nipru/Dnieper; the Bolohoveni disappeared from chronicles after their defeat in 1257 by Daniel of Galicia's troops. In the early 13th century, the Brodniks, a possible Slavic–Vlach vassal state of Halych, were present, alongside the Vlachs, in much of the region's territory. On the border between Halych and the
The Balkans known as the Balkan Peninsula, is a geographic area in southeastern Europe with various definitions and meanings, including geopolitical and historical. The region takes its name from the Balkan Mountains that stretch throughout the whole of Bulgaria from the Serbian-Bulgarian border to the Black Sea coast; the Balkan Peninsula is bordered by the Adriatic Sea on the northwest, the Ionian Sea on the southwest, the Aegean Sea in the south and southeast, the Black Sea on the east and northeast. The northern border of the peninsula is variously defined; the highest point of the Balkans is 2,925 metres, in the Rila mountain range. The concept of the Balkan peninsula was created by the German geographer August Zeune in 1808, who mistakenly considered the Balkan Mountains the dominant mountain system of Southeast Europe spanning from the Adriatic Sea to the Black Sea; the term of Balkan Peninsula was a synonym for European Turkey in the 19th century, the former provinces of the Ottoman Empire in Southeast Europe.
It had a geopolitical rather than a geographical definition, further promoted during the creation of the Kingdom of Yugoslavia in the early 20th century. The definition of the Balkan peninsula's natural borders do not coincide with the technical definition of a peninsula and hence modern geographers reject the idea of a Balkan peninsula, while scholars discuss the Balkans as a region; the term has acquired a stigmatized and pejorative meaning related to the process of Balkanization, hence the rather used alternative term for the region is Southeast Europe. The word Balkan comes from Ottoman Turkish balkan'chain of wooded mountains'; the origin of the Turkic word is obscure. From classical antiquity through the Middle Ages, the Balkan Mountains were called by the local Thracian name Haemus. According to Greek mythology, the Thracian king Haemus was turned into a mountain by Zeus as a punishment and the mountain has remained with his name. A reverse name scheme has been suggested. D. Dechev considers that Haemus is derived from a Thracian word *saimon,'mountain ridge'.
A third possibility is that "Haemus" derives from the Greek word "haema" meaning'blood'. The myth relates to a fight between the monster/titan Typhon. Zeus injured Typhon with a thunder bolt and Typhon's blood fell on the mountains, from which they got their name; the earliest mention of the name appears in an early 14th-century Arab map, in which the Haemus mountains are referred to as Balkan. The first attested time the name "Balkan" was used in the West for the mountain range in Bulgaria was in a letter sent in 1490 to Pope Innocent VIII by Buonaccorsi Callimaco, an Italian humanist and diplomat; the Ottomans first mention it in a document dated from 1565. There has been no other documented usage of the word to refer to the region before that, although other Turkic tribes had settled in or were passing through the Peninsula. There is a claim about an earlier Bulgar Turkic origin of the word popular in Bulgaria, however it is only an unscholarly assertion; the word was used by the Ottomans in Rumelia in its general meaning of mountain, as in Kod̲j̲a-Balkan, Čatal-Balkan, Ungurus-Balkani̊, but it was applied to the Haemus mountain.
The name is still preserved in Central Asia with the Balkan Daglary and the Balkan Province of Turkmenistan. English traveler John Morritt introduced this term into the English literature at the end of the 18th-century, other authors started applying the name to the wider area between the Adriatic and the Black Sea; the concept of the "Balkans" was created by the German geographer August Zeune in 1808, who mistakenly considered it as the dominant central mountain system of Southeast Europe spanning from the Adriatic Sea to the Black Sea. During the 1820s, "Balkan became the preferred although not yet exclusive term alongside Haemus among British travelers... Among Russian travelers not so burdened by classical toponymy, Balkan was the preferred term"; the term was not used in geographical literature until the mid-19th century because then scientists like Carl Ritter warned that only the part South of the Balkan Mountains can be considered as a peninsula and considered it to be renamed as "Greek peninsula".
Other prominent geographers who didn't agree with Zeune were Hermann Wagner, Theobald Fischer, Marion Newbigin, Albrecht Penck, while Austrian diplomat Johann Georg von Hahn in 1869 for the same territory used the term Südostereuropäische Halbinsel. Another reason it was not accepted as the definition of European Turkey had a similar land extent. However, after the Congress of Berlin there was a political need for a new term and the Balkans was revitalized, but in the maps the northern border was in Serbia and Montenegro without Greece, while Yugoslavian maps included Croatia and Bosnia; the term Balkan Peninsula was a synonym for European Turkey, the political borders of former Ottoman Empire provinces. The usage of the term changed in the end of the 19th and beginning of the 20th century when was embraced by Serbian geographers, most prominently by Jovan Cvijić, it was done with political reasoning as affirmation for Serbian nationalism on the whole territory of the South Slavs, included anthropological and ethnological studies of the South Slavs through which were claimed various nationalistic and racistic theories.
Through such policies and Yugoslavian maps the term was elevated to the modern status of
Woodwind instruments are a family of musical instruments within the more general category of wind instruments. There are two main types of woodwind instruments: reed instruments. What differentiates these instruments from other wind instruments is the way in which they produce their sound. All woodwinds produce sound by splitting an exhaled air stream on a sharp edge, such as a reed or a fipple. A woodwind may be made of any material, not just wood. Common examples include brass, cane, as well as other metals such as gold and platinum. Woodwinds are made out of earthen materials ocarinas. Common examples include flute, clarinet and saxophone. Flutes produce sound by directing a focused stream of air below the edge of a hole in a cylindrical tube; the flute family can be divided into two sub-families: closed flutes. To produce a sound with an open flute, the player is required to blow a stream of air across a sharp edge that splits the airstream; this split airstream acts upon the air column contained within the flute's hollow causing it to vibrate and produce sound.
Examples of open flutes are the transverse flute and shakuhachi. Ancient flutes of this variety were made from tubular sections of plants such as grasses and hollowed-out tree branches. Flutes were made of metals such as tin, copper, or bronze. Modern concert flutes are made of high-grade metal alloys containing nickel, copper, or gold. To produce a sound with a closed flute, the player is required to blow air into a duct; this duct acts as a channel bringing the air to a sharp edge. As with the open flutes, the air is split. Examples of this type of flute include the recorder and organ pipes. Reed instruments produce sound by focusing air into a mouthpiece which causes a reed, or reeds, to vibrate. Similar to flutes, Reed pipes are further divided into two types: single reed and double reed. Single-reed woodwinds produce sound by placing a reed onto the opening of a mouthpiece; when air is forced between the reed and the mouthpiece, the reed causes the air column in the instrument to vibrate and produce its unique sound.
Single reed instruments include the clarinet and others such as the chalumeau. Double-reed instruments use two cut, small pieces of cane bound together at the base; this form of sound production has been estimated to have originated in the middle to late Neolithic period. The finished, bound reed is inserted into the instrument and vibrates as air is forced between the two pieces; this family of reed pipes is subdivided further into another two sub-families: exposed double reed, capped double reed instruments. Exposed double-reed instruments are played by having the double reed directly between the player's lips; this family includes instruments such as the oboe, cor anglais and bassoon, many types of shawms throughout the world. On the other hand, Capped double-reed instruments have the double reed covered by a cap; the player blows through a hole in this cap that directs the air through the reeds. This family includes the crumhorn. Bagpipes are unique reed pipe instruments since they use two or more single reeds.
However, bagpipes are functionally the same as a capped double reed instruments since the reeds are never in direct contact with player's lips. Free reed aerophone instruments are unique since sound is produced by'free reeds' – small metal tongues arranged in rows within a metal or wooden frame; the airflow necessary for the instruments sound is generated either by a player's breath, or by bellows. The modern orchestra's woodwind section includes: flutes, oboes and bassoons; the piccolo, cor anglais, bass clarinet, E-flat clarinet, contrabassoon are used supplementary woodwind instruments. The section may on occasion be expanded by the addition of saxophone; the concert band's woodwind section is much larger and more diverse than the orchestra's. The concert band's woodwind section includes piccolos, oboes, B♭ clarinets, bass clarinets, alto saxophones, tenor saxophones, baritone saxophones; the cor anglais, E♭ clarinet, alto clarinet, contra-alto clarinet, contrabass clarinet and soprano saxophone are used, but not as as the other woodwinds.

A musical instrument is an instrument created or adapted to make musical sounds. In principle, any object that produces sound can be considered a musical instrument—it is through purpose that the object becomes a musical instrument; the history of musical instruments dates to the beginnings of human culture. Early musical instruments may have been used for ritual, such as a trumpet to signal success on the hunt, or a drum in a religious ceremony. Cultures developed composition and performance of melodies for entertainment. Musical instruments evolved in step with changing applications; the date and origin of the first device considered. The oldest object that some scholars refer to as a musical instrument, a simple flute, dates back as far as 67,000 years; some consensus dates early flutes to about 37,000 years ago. However, most historians believe that determining a specific time of musical instrument invention is impossible due to the subjectivity of the definition and the relative instability of materials used to make them.
Many early musical instruments were made from animal skins, bone and other non-durable materials. Musical instruments developed independently in many populated regions of the world. However, contact among civilizations caused rapid spread and adaptation of most instruments in places far from their origin. By the Middle Ages, instruments from Mesopotamia were in maritime Southeast Asia, Europeans played instruments from North Africa. Development in the Americas occurred at a slower pace, but cultures of North and South America shared musical instruments. By 1400, musical instrument development was dominated by the Occident. Musical instrument classification is a discipline in its own right, many systems of classification have been used over the years. Instruments can be classified by their material composition, their size, etc.. However, the most common academic method, Hornbostel-Sachs, uses the means by which they produce sound; the academic study of musical instruments is called organology. A musical instrument makes sounds.
Once humans moved from making sounds with their bodies—for example, by clapping—to using objects to create music from sounds, musical instruments were born. Primitive instruments were designed to emulate natural sounds, their purpose was ritual rather than entertainment; the concept of melody and the artistic pursuit of musical composition were unknown to early players of musical instruments. A player sounding a flute to signal the start of a hunt does so without thought of the modern notion of "making music". Musical instruments are constructed in a broad array of styles and shapes, using many different materials. Early musical instruments were made from "found objects" such a shells and plant parts; as instruments evolved, so did the selection and quality of materials. Every material in nature has been used by at least one culture to make musical instruments. One plays a musical instrument by interacting with it in some way—for example, by plucking the strings on a string instrument. Researchers have discovered archaeological evidence of musical instruments in many parts of the world.
Some finds are 67,000 years old, however their status as musical instruments is in dispute. Consensus solidifies about artifacts dated back to around 37,000 years old and later. Only artifacts made from durable materials or using durable methods tend to survive; as such, the specimens found. In July 1995, Slovenian archaeologist Ivan Turk discovered a bone carving in the northwest region of Slovenia; the carving, named the Divje Babe Flute, features four holes that Canadian musicologist Bob Fink determined could have been used to play four notes of a diatonic scale. Researchers estimate the flute's age at between 43,400 and 67,000 years, making it the oldest known musical instrument and the only musical instrument associated with the Neanderthal culture. However, some archaeologists and ethnomusicologists dispute the flute's status as a musical instrument. German archaeologists have found mammoth bone and swan bone flutes dating back to 30,000 to 37,000 years old in the Swabian Alps; the flutes were made in the Upper Paleolithic age, are more accepted as being the oldest known musical instruments.
Archaeological evidence of musical instruments was discovered in excavations at the Royal Cemetery in the Sumerian city of Ur. These instruments, one of the first ensembles of instruments yet discovered, include nine lyres, two harps, a silver double flute and cymbals. A set of reed-sounded silver pipes discovered in Ur was the predecessor of modern bagpipes; the cylindrical pipes feature three side-holes. These excavations, carried out by Leonard Woolley in the 1920s, uncovered non-degradable fragments of instruments and the voids left by the degraded segments that, have been used to reconstruct them; the graves these instruments were buried in have been carbon dated to between 2600 and 2500 BC, providing evidence that these instruments were used in Sumeria by this time. Archaeologists in the Jiahu site of central Henan province of China have found flutes made of bones that date back 7,000 to 9,000 years, representing some of the "earliest complete, tightly-dated, multinote musical instruments" found.
Scholars agree that there are no reliable methods of determining the exact chronology of musical instruments across cultures. Comparing and organizing instruments based on their complexity is misleading, since advancements in musical instruments have sometimes reduced complexity. For example, construction of early slit drums involved f
The chanter is the part of the bagpipe upon which the player creates the melody. It consists of a number of finger-holes, in its simpler forms looks similar to a recorder. On more elaborate bagpipes, such as the Northumbrian bagpipes or the Uilleann pipes, it may have a number of keys, to increase the instrument's range and/or the number of keys it can play in. Like the rest of the bagpipe, they are decorated with a variety of substances, including metal, ivory, or plastic mountings. Chanters come in two main types and non-parallel bored; this refers to the shape of the internal bore of the chanter. On the Great Highland Bagpipe, the internal bore is conical: it is this that gives the chanter its exceptional volume; the Northumbrian pipes, on the other hand, have a parallel bore, giving them a much sweeter and quieter tone. Although the majority of chanters are unkeyed, some make extensive use of keys to extend the range and/or the number of accidentals the chanter can play; the most common pipe featuring this arrangement is the Northumbrian smallpipe.
Another variant of the chanter is the two-piped chanter. The chanter pipes may be designed to be played separately, one with each hand, or the two chanters may be played in unison. One chanter may provide a drone accompaniment to the other, or the two chanters may play in a harmony of thirds and sixths. In pipes of the Carpathian basin up to five separate chanter bores may be placed in parallel within a single chanter assembly, providing both melodic and rhythmic possibilities: in the simplest case, one pipe is used to play the melody while the second provides a variable drone, while more complex pipes may separate certain individual notes into separate, stopped pipes; because of the accompanying drone or drones, the lack of modulation in bagpipe melody, stable timbre of the reed sound, in many bagpipe traditions the tones of the chanter are tuned using just intonation, although bagpipe tuning is variable across traditions. On the Great Highland bagpipe, tuning of the individual notes of the chanter is done using tape to cover the finger holes as needed.
It was done with wax, as was done with other woodwind instruments. The practice chanter is used as a practice instrument for the Great Highland Bagpipe, it is somewhat similar in appearance, though smaller than the bagpipe chanter, has a top piece so it can be blown directly from the mouth. It is used as a first instrument so that learners can learn the finger technique before learning the mechanics of controlling the bag, it is exclusively made of hardwood or plastic. The practice chanter of today may be a descendant of the hornpipe or "stock-and-horn", a historical reed pipe of Scotland with a capped double reed and bell made of horn, played by shepherds, among others
Romania is a country located at the crossroads of Central and Southeastern Europe. It borders the Black Sea to the southeast, Bulgaria to the south, Ukraine to the north, Hungary to the west, Serbia to the southwest, Moldova to the east, it has a predominantly temperate-continental climate. With a total area of 238,397 square kilometres, Romania is the 12th largest country and the 7th most populous member state of the European Union, having 20 million inhabitants, its capital and largest city is Bucharest, other major urban areas include Cluj-Napoca, Timișoara, Iași, Constanța, Brașov. The River Danube, Europe's second-longest river, rises in Germany's Black Forest and flows in a general southeast direction for 2,857 km, coursing through ten countries before emptying into Romania's Danube Delta; the Carpathian Mountains, which cross Romania from the north to the southwest, include Moldoveanu Peak, at an altitude of 2,544 m. Modern Romania was formed in 1859 through a personal union of the Danubian Principalities of Moldavia and Wallachia.
The new state named Romania since 1866, gained independence from the Ottoman Empire in 1877. Following World War I, when Romania fought on the side of the Allied powers, Bessarabia, Transylvania as well as parts of Banat, Crișana, Maramureș became part of the sovereign Kingdom of Romania. In June–August 1940, as a consequence of the Molotov–Ribbentrop Pact and Second Vienna Award, Romania was compelled to cede Bessarabia and Northern Bukovina to the Soviet Union, Northern Transylvania to Hungary. In November 1940, Romania signed the Tripartite Pact and in June 1941 entered World War II on the Axis side, fighting against the Soviet Union until August 1944, when it joined the Allies and recovered Northern Transylvania. Following the war, under the occupation of the Red Army's forces, Romania became a socialist republic and member of the Warsaw Pact. After the 1989 Revolution, Romania began a transition back towards a market economy; the sovereign state of Romania is a developing country and ranks 52nd in the Human Development Index.
It has the world's 47th largest economy by nominal GDP and an annual economic growth rate of 7%, the highest in the EU at the time. Following rapid economic growth in the early 2000s, Romania has an economy predominantly based on services, is a producer and net exporter of machines and electric energy, featuring companies like Automobile Dacia and OMV Petrom, it has been a member of the United Nations since 1955, part of NATO since 2004, part of the European Union since 2007. An overwhelming majority of the population identifies themselves as Eastern Orthodox Christians and are native speakers of Romanian, a Romance language. Romania derives from the Latin romanus, meaning "citizen of Rome"; the first known use of the appellation was attested to in the 16th century by Italian humanists travelling in Transylvania and Wallachia. The oldest known surviving document written in Romanian, a 1521 letter known as the "Letter of Neacșu from Câmpulung", is notable for including the first documented occurrence of the country's name: Wallachia is mentioned as Țeara Rumânească.
Two spelling forms: român and rumân were used interchangeably until sociolinguistic developments in the late 17th century led to semantic differentiation of the two forms: rumân came to mean "bondsman", while român retained the original ethnolinguistic meaning. After the abolition of serfdom in 1746, the word rumân fell out of use and the spelling stabilised to the form român. Tudor Vladimirescu, a revolutionary leader of the early 19th century, used the term Rumânia to refer to the principality of Wallachia."The use of the name Romania to refer to the common homeland of all Romanians—its modern-day meaning—was first documented in the early 19th century. The name has been in use since 11 December 1861. In English, the name of the country was spelt Rumania or Roumania. Romania became the predominant spelling around 1975. Romania is the official English-language spelling used by the Romanian government. A handful of other languages have switched to "o" like English, but most languages continue to prefer forms with u, e.g. French Roumanie and Swedish Rumänien, Spanish Rumania, Polish Rumunia, Russian Румыния, Japanese ルーマニア.

Neolithic techniques and agriculture spread after the arrival of a mixed group of people from Thessaly in the 6th millenium BC. Excavations near a salt spring at Lunca yielded the earliest evidence for salt exploitation in Europe; the first permanent settlements appeared in the Neolithic. Some of them developed into "proto-cities"; the Cucuteni–Trypillia culture—the best known archaeological culture of Old Europe—flourished in Muntenia, southeastern Transylvania and northeastern Moldavia in the 3rd m
Musical instrument classification
Throughout history, various methods of musical instrument classification have been used. The most used system divides instruments into string instruments, woodwind instruments, brass instruments and percussion instruments; the oldest known scheme of classifying instruments is Chinese and dates from the 3rd millennium BC. It grouped instruments according to the materials they are made of. Instruments made of stone were in one group, those of wood in another, those of silk are in a third, those of bamboo in a fourth, as recorded in the Yo Chi, compiled from sources of the Chou period and corresponding to the four seasons and four winds; the eight-fold system of pa yin, from the same source, occurred and in the legendary Emperor Zhun's time it is believed to have been presented in the following order: metal, silk, gourd, clay and wood classes, it correlated to the eight seasons and eight winds of Chinese culture and west, autumn-winter and NW, summer and south and east, winter-spring and NE, summer-autumn and SW, winter and north, spring-summer and SE, respectively.
However, the Chou-Li, an anonymous treatise compiled from earlier sources in about the 2nd century BC, had the following order: metal, clay, silk, wood and bamboo. The same order was presented in the Tso Chuan, attributed to Tso Chiu-Ming compiled in the 4th century BC. Much Ming dynasty scholar Chu Tsai Yu recognized three groups: those instruments using muscle power or used for musical accompaniment, those that are blown, those that are rhythmic, a scheme, the first scholarly attempt, while the earlier ones were traditional, folk taxonomies. More instruments are classified according to how the sound is produced; the modern system divides instruments into wind and percussion. It is of Greek origin; the scheme was expanded by Martin Agricola, who distinguished plucked string instruments, such as guitars, from bowed string instruments, such as violins. Classical musicians today do not always maintain this division, but distinguish between wind instruments with a reed and those where the air is set in motion directly by the lips.
Many instruments do not fit neatly into this scheme. The serpent, for example, ought to be classified as a brass instrument, as a column of air is set in motion by the lips. However, it looks more like a woodwind instrument, is closer to one in many ways, having finger-holes to control pitch, rather than valves. Keyboard instruments do not fit into this scheme. For example, the piano has strings, but they are struck by hammers, so it is not clear whether it should be classified as a string instrument or a percussion instrument. For this reason, keyboard instruments are regarded as inhabiting a category of their own, including all instruments played by a keyboard, whether they have struck strings, plucked strings or no strings at all, it might be said that with these extra categories, the classical system of instrument classification focuses less on the fundamental way in which instruments produce sound, more on the technique required to play them. Various names have been assigned to these three traditional Western groupings: Boethius labelled them intensione ut nervis, spiritu ut tibiis, percussione.
Ottoman encyclopedist Hadji Khalifa recognized the same three classes in his Kashf al-Zunun an Asami al-Kutub wa al-Funun, a treatise on the origin and construction of musical instruments. But this was exceptional for Near Eastern writers as they ignored the percussion group as did early Hellenistic Greeks, the Near Eastern culture traditionally and that period of Greek history having low regard for that group; the T'boli of Mindanao use the same three categories as well, but group the strings with the winds together based on a gentleness-strength dichotomy, re
