String instrument
–
String instruments, stringed instruments, or chordophones are musical instruments that produce sound from vibrating strings when the performer plays or sounds the strings in some manner. Musicians play some string instruments by plucking the strings with their fingers or a plectrum—and others by hitting the strings with a wooden hammer or by rubbing the strings with a bow. In some keyboard instruments, such as the harpsichord or piano, with bowed instruments, the player rubs the strings with a horsehair bow, causing them to vibrate. With a hurdy-gurdy, the musician operates a wheel that rubs the strings. Bowed instruments include the string instruments of the Classical music orchestra. All of the string instruments can also be plucked with the fingers. Some types of string instrument are mainly plucked, such as the harp, in the Hornbostel-Sachs scheme of musical instrument classification, used in organology, string instruments are called chordophones. Other examples include the sitar, rebab, banjo, mandolin, ukulele, in most string instruments, the vibrations are transmitted to the body of the instrument, which often incorporates some sort of hollow or enclosed area. The body of the instrument also vibrates, along with the air inside it, the vibration of the body of the instrument and the enclosed hollow or chamber make the vibration of the string more audible to the performer and audience. The body of most string instruments is hollow, some, however—such as electric guitar and other instruments that rely on electronic amplification—may have a solid wood body. Archaeological digs have identified some of the earliest stringed instruments in Ancient Mesopotamian sites, like the lyres of Ur, the development of lyre instruments required the technology to create a tuning mechanism to tighten and loosen the string tension. During the medieval era, instrument development varied from country to country, Middle Eastern rebecs represented breakthroughs in terms of shape and strings, with a half a pear shape using three strings. Early versions of the violin and fiddle, by comparison, emerged in Europe through instruments such as the gittern, a four stringed precursor to the guitar and these instruments typically used catgut and other materials, including silk, for their strings. String instrument design refined during the Renaissance and into the Baroque period of musical history, violins and guitars became more consistent in design, and were roughly similar to what we use in the 2000s. At the same time, the 19th century guitar became more associated with six string models. In big bands of the 1920s, the guitar played backing chords. The development of guitar amplifiers, which contained a power amplifier, the development of the electric guitar provided guitarists with an instrument that was built to connect to guitar amplifiers. Electric guitars have magnetic pickups, volume control knobs and an output jack, in the 1960s, larger, more powerful guitar amplifiers were developed, called stacks

Woodwind instrument
–
Woodwind instruments are a family of musical instruments within the more general category of wind instruments. There are two types of woodwind instruments, flutes and reed instruments. What differentiates these instruments from other instruments is the way in which they produce their sound. Examples are a saxophone, a bassoon and a piccolo, 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, open flutes and 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 then splits the airstream. This split airstream then acts upon the air contained within the flutes hollow causing it to vibrate. Examples of open flutes are the flute, panpipes and shakuhachi. Ancient flutes of this variety were often made from sections of plants such as grasses, reeds. Later, flutes were made of such as tin, copper. Modern concert flutes are made of high-grade metal alloys, usually containing nickel, silver, copper. To produce a sound with a 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 then split, this causes the column of air within the closed flute to vibrate and produce sound. Examples of this type of include the recorder, ocarina. Reed instruments produce sound by focusing air into a mouthpiece which then causes a reed, or reeds, similar to flutes, Reed pipes are also 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, saxophone, and others such as the chalumeau, double-reed instruments use two precisely cut, small pieces of cane bound together at the base. This form of 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 and this family of reed pipes is subdivided further into another two sub-families, exposed double reed, and capped double reed instruments

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

Percussion instrument
–
A percussion instrument is a musical instrument that is sounded by being struck or scraped by a beater, struck, scraped or rubbed by hand, or struck against another similar instrument. The percussion family is believed to include the oldest musical instruments, the percussion section of an orchestra most commonly contains instruments such as timpani, snare drum, bass drum, cymbals, triangle and tambourine. However, the section can also contain non-percussive instruments, such as whistles and sirens, percussive techniques can also be applied to the human body, as in body percussion. On the other hand, keyboard instruments, such as the celesta, are not normally part of the percussion section, Percussion instruments may play not only rhythm, but also melody and harmony. Percussion is commonly referred to as the backbone or the heartbeat of an ensemble, often working in close collaboration with bass instruments. In jazz and other popular ensembles, the pianist, bassist, drummer. Most classical pieces written for full orchestra since the time of Haydn and Mozart are orchestrated to place emphasis on the strings, woodwinds, however, often at least one pair of timpani is included, though they rarely play continuously. Rather, they serve to provide additional accents when needed, in the 18th and 19th centuries, other percussion instruments have been used, again generally sparingly. The use of percussion instruments became more frequent in the 20th century classical music, in almost every style of music, percussion plays a pivotal role. In classic jazz, one almost immediately thinks of the rhythm of the hi-hats or the ride cymbal when the word swing is spoken. Because of the diversity of instruments, it is not uncommon to find large musical ensembles composed entirely of percussion. Rhythm, melody, and harmony are all represented in these ensembles, music for pitched percussion instruments can be notated on a staff with the same treble and bass clefs used by many non-percussive instruments. Music for percussive instruments without a pitch can be notated with a specialist rhythm or percussion-clef. The word percussion has evolved from Latin terms, percussio, as a noun in contemporary English it is described in Wiktionary as the collision of two bodies to produce a sound. Hornbostel–Sachs has no high-level section for percussion, Most percussion instruments are classified as idiophones and membranophones.1 Concussion idiophones or clappers, played in pairs and beaten against each other, such as zills and clapsticks. 111.2 Percussion idiophones, includes many percussion instruments played with the hand or by a mallet, such as the hang, gongs and the xylophone. 21 Struck drums, includes most types of drum, such as the timpani, snare drum, (Included in most drum sets or 412. Stringed instruments played with such as the hammered dulcimer

China
–
China, officially the Peoples Republic of China, is a unitary sovereign state in East Asia and the worlds most populous country, with a population of over 1.381 billion. The state is governed by the Communist Party of China and its capital is Beijing, the countrys major urban areas include Shanghai, Guangzhou, Beijing, Chongqing, Shenzhen, Tianjin and Hong Kong. China is a power and a major regional power within Asia. Chinas landscape is vast and diverse, ranging from forest steppes, the Himalaya, Karakoram, Pamir and Tian Shan mountain ranges separate China from much of South and Central Asia. The Yangtze and Yellow Rivers, the third and sixth longest in the world, respectively, Chinas coastline along the Pacific Ocean is 14,500 kilometers long and is bounded by the Bohai, Yellow, East China and South China seas. China emerged as one of the worlds earliest civilizations in the basin of the Yellow River in the North China Plain. For millennia, Chinas political system was based on hereditary monarchies known as dynasties, in 1912, the Republic of China replaced the last dynasty and ruled the Chinese mainland until 1949, when it was defeated by the communist Peoples Liberation Army in the Chinese Civil War. The Communist Party established the Peoples Republic of China in Beijing on 1 October 1949, both the ROC and PRC continue to claim to be the legitimate government of all China, though the latter has more recognition in the world and controls more territory. China had the largest economy in the world for much of the last two years, during which it has seen cycles of prosperity and decline. Since the introduction of reforms in 1978, China has become one of the worlds fastest-growing major economies. As of 2016, it is the worlds second-largest economy by nominal GDP, China is also the worlds largest exporter and second-largest importer of goods. China is a nuclear weapons state and has the worlds largest standing army. The PRC is a member of the United Nations, as it replaced the ROC as a permanent member of the U. N. Security Council in 1971. China is also a member of numerous formal and informal multilateral organizations, including the WTO, APEC, BRICS, the Shanghai Cooperation Organization, the BCIM, the English name China is first attested in Richard Edens 1555 translation of the 1516 journal of the Portuguese explorer Duarte Barbosa. The demonym, that is, the name for the people, Portuguese China is thought to derive from Persian Chīn, and perhaps ultimately from Sanskrit Cīna. Cīna was first used in early Hindu scripture, including the Mahābhārata, there are, however, other suggestions for the derivation of China. The official name of the state is the Peoples Republic of China. The shorter form is China Zhōngguó, from zhōng and guó and it was then applied to the area around Luoyi during the Eastern Zhou and then to Chinas Central Plain before being used as an occasional synonym for the state under the Qing

Rock (geology)
–
Rock or stone is a natural substance, a solid aggregate of one or more minerals or mineraloids. For example, granite, a rock, is a combination of the minerals quartz, feldspar. The Earths outer solid layer, the lithosphere, is made of rock, rock has been used by mankind throughout history. The minerals and metals found in rocks have been essential to human civilization, three major groups of rocks are defined, igneous, sedimentary, and metamorphic. The scientific study of rocks is called petrology, which is a component of geology. At a granular level, rocks are composed of grains of minerals, the aggregate minerals forming the rock are held together by chemical bonds. The types and abundance of minerals in a rock are determined by the manner in which the rock was formed, many rocks contain silica, a compound of silicon and oxygen that forms 74. 3% of the Earths crust. This material forms crystals with other compounds in the rock, the proportion of silica in rocks and minerals is a major factor in determining their name and properties. Rocks are geologically classified according to such as mineral and chemical composition, permeability, the texture of the constituent particles. These physical properties are the end result of the processes that formed the rocks, over the course of time, rocks can transform from one type into another, as described by the geological model called the rock cycle. These events produce three general classes of rock, igneous, sedimentary, and metamorphic, the three classes of rocks are subdivided into many groups. However, there are no hard and fast boundaries between allied rocks, hence the definitions adopted in establishing rock nomenclature merely correspond to more or less arbitrary selected points in a continuously graduated series. Igneous rock forms through the cooling and solidification of magma or lava and this magma can be derived from partial melts of pre-existing rocks in either a planets mantle or crust. Typically, the melting of rocks is caused by one or more of three processes, an increase in temperature, a decrease in pressure, or a change in composition, igneous rocks are divided into two main categories, plutonic rock and volcanic. Plutonic or intrusive rocks result when magma cools and crystallizes slowly within the Earths crust, a common example of this type is granite. Volcanic or extrusive rocks result from magma reaching the surface either as lava or fragmental ejecta, the chemical abundance and the rate of cooling of magma typically forms a sequence known as Bowens reaction series. Most major igneous rocks are found along this scale, about 64. 7% of the Earths crust by volume consists of igneous rocks, making it the most plentiful category. Of these, 66% are basalts and gabbros, 16% are granite, only 0. 6% are syenites and 0. 3% peridotites and dunites

Wood
–
Wood is a porous and fibrous structural tissue found in the stems and roots of trees, and other woody plants. It is a material, a natural composite of cellulose fibers which are strong in tension embedded in a matrix of lignin which resists compression. Wood is sometimes defined as only the secondary xylem in the stems of trees, in a living tree it performs a support function, enabling woody plants to grow large or to stand up by themselves. It also conveys water and nutrients between the leaves, other growing tissues, and the roots, Wood may also refer to other plant materials with comparable properties, and to material engineered from wood, or wood chips or fiber. In 2005, the stock of forests worldwide was about 434 billion cubic meters. As an abundant, carbon-neutral renewable resource, woody materials have been of intense interest as a source of renewable energy, in 1991 approximately 3.5 billion cubic meters of wood were harvested. Dominant uses were for furniture and building construction, a 2011 discovery in the Canadian province of New Brunswick discovered the earliest known plants to have grown wood, approximately 395 to 400 million years ago. Wood can be dated by carbon dating and in species by dendrochronology to make inferences about when a wooden object was created. People have used wood for millennia for many purposes, primarily as a fuel or as a material for making houses, tools, weapons, furniture, packaging, artworks. Constructions using wood date back ten thousand years, buildings like the European Neolithic long house were made primarily of wood. Recent use of wood has changed by the addition of steel. The year-to-year variation in tree-ring widths and isotopic abundances gives clues to the climate at that time. This process is known as growth, it is the result of cell division in the vascular cambium, a lateral meristem. These cells then go on to form thickened secondary cell walls, composed mainly of cellulose, hemicellulose, if the distinctiveness between seasons is annual, these growth rings are referred to as annual rings. Where there is little seasonal difference growth rings are likely to be indistinct or absent, if the bark of the tree has been removed in a particular area, the rings will likely be deformed as the plant overgrows the scar. It is usually lighter in color than that near the portion of the ring. The outer portion formed later in the season is known as the latewood or summerwood. However, there are differences, depending on the kind of wood

Silk
–
Silk is a natural protein fiber, some forms of which can be woven into textiles. The protein fiber of silk is composed mainly of fibroin and is produced by insect larvae to form cocoons. The best-known silk is obtained from the cocoons of the larvae of the mulberry silkworm Bombyx mori reared in captivity, Silk is produced by several insects, but generally only the silk of moth caterpillars has been used for textile manufacturing. There has been research into other types of silk, which differ at the molecular level. Silk is mainly produced by the larvae of insects undergoing complete metamorphosis, Silk production also occurs in Hymenoptera, silverfish, mayflies, thrips, leafhoppers, beetles, lacewings, fleas, flies, and midges. Other types of arthropod produce silk, most notably various arachnids such as spiders, the word silk comes from Old English sioloc, from Greek σηρικός serikos, silken, ultimately from an Asian source. Several kinds of silk, which are produced by caterpillars other than the mulberry silkworm, have been known and used in China, South Asia. However, the scale of production was far smaller than for cultivated silks. Thus, the way to obtain silk suitable for spinning into textiles in areas where commercial silks are not cultivated was by tedious. Commercial silks originate from reared silkworm pupae, which are bred to produce a silk thread with no mineral on the surface. The pupae are killed by either dipping them in boiling water before the adult moths emerge or by piercing them with a needle. These factors all contribute to the ability of the cocoon to be unravelled as one continuous thread. Wild silks also tend to be difficult to dye than silk from the cultivated silkworm. Genetic modification of domesticated silkworms is used to facilitate the production of more types of silk. Silk fabric was first developed in ancient China, the earliest example of silk fabric is from 3630 BC, and it was used as wrapping for the body of a child from a Yangshao culture site in Qingtaicun at Xingyang, Henan. Legend gives credit for developing silk to a Chinese empress, Leizu, because of its texture and lustre, silk rapidly became a popular luxury fabric in the many areas accessible to Chinese merchants. Silk was in demand, and became a staple of pre-industrial international trade. In July 2007, archaeologists discovered intricately woven and dyed silk textiles in a tomb in Jiangxi province, Silk is described in a chapter on mulberry planting by Si Shengzhi of the Western Han

Bamboo
–
The bamboos /bæmˈbuː/ are evergreen perennial flowering plants in the subfamily Bambusoideae of the grass family Poaceae. The dicotyledonous woody xylem is also absent, the absence of secondary growth wood causes the stems of monocots, including the palms and large bamboos, to be columnar rather than tapering. Bamboos include some of the plants in the world, due to a unique rhizome-dependent system. Certain species of bamboo can grow 91 cm within a 24-hour period, giant bamboos are the largest members of the grass family. Bamboos are of economic and cultural significance in South Asia, Southeast Asia and East Asia, being used for building materials, as a food source. Bamboo has a higher compressive strength than wood, brick, or concrete. The word bamboo comes from the Kannada term bambu, which was introduced to English through Indonesian, the subfamily in its current sense belongs to the BOP clade of grasses, where it is sister to the Pooideae. The woody bamboos do not form a group, instead. Altogether, more than 1,400 species are placed in 115 genera, most bamboo are native to warm and moist tropical and warm temperate climates. However, many species are found in climates, from hot tropical regions to cool mountainous regions. In the Asia-Pacific region they occur across East Asia, from 50°N latitude in Sakhalin south to Northern Australia, and west to India, China, Japan, Korea, India, and Australia, all have several endemic populations. They also occur in numbers in sub-Saharan Africa, confined to tropical areas, from southern Senegal in the north to southern Mozambique. Bamboo is also native through Central America and Mexico, northward into the Southeastern United States, canada and continental Europe is not known to have any native species of bamboo. Recently, some attempts have been made to grow bamboo on a basis in the Great Lakes region of east-central Africa. In the United States, several companies are growing, harvesting, bamboos include some of the fastest-growing plants on Earth, with reported growth rates up to 91 cm in 24 hours. Primarily growing in regions of warmer climates during the late Cretaceous period, some of the largest timber bamboo can grow over 30 m tall, and be as large as 25–30 cm in diameter. However, the range for mature bamboo is species-dependent, with the smallest bamboos reaching only several inches high at maturity. A typical height range that would cover many of the common bamboos grown in the United States is 4. 6–12 m, depending on species

Zhou dynasty
–
The Zhou dynasty was a Chinese dynasty that followed the Shang dynasty and preceded the Qin dynasty. This period of Chinese history produced what many consider the zenith of Chinese bronze-ware making, the dynasty also spans the period in which the written script evolved into its almost-modern form with the use of an archaic clerical script that emerged during the late Warring States period. He even received sacrifice as a harvest god, the term Hòujì was probably an hereditary title attached to a lineage. Jus son Liu, however, led his people to prosperity by restoring agriculture and settling them at a place called Bin, tai later led the clan from Bin to Zhou, an area in the Wei River valley of modern-day Qishan County. Taibo and Zhongyong had supposedly fled to the Yangtze delta. Jilis son Wen bribed his way out of imprisonment and moved the Zhou capital to Feng, the Zhou enfeoffed a member of the defeated Shang royal family as the Duke of Song, which was held by descendants of the Shang royal family until its end. This practice was referred to as Two Kings, Three Reverences, according to Nicholas Bodman, the Zhou appear to have spoken a language not basically different in vocabulary and syntax from that of the Shang. A recent study by David McCraw, using lexical statistics, reached the same conclusion, the Zhou emulated extensively Shang cultural practices, perhaps to legitimize their own rule, and became the successors to Shang culture. At the same time, the Zhou may also have connected to the Xirong, a broadly defined cultural group to the west of the Shang. According to the historian Li Feng, the term Rong during the Western Zhou period was used to designate political and military adversaries rather than cultural. The proto-Zhou were first located in the Shaanxi-Shanxi highland, where they absorbed elements from the Guangshe culture, King Liu moved his people to the lower Fen Valley and to the western bank of the Yellow River, where they resumed agriculture. His son Qing Jie, led the Zhou to the valley of the Jing River. They stayed there until Dan Fu moved again to the Wei Valley in order to avoid incursion by the Rongdi nomads. During this period, the Zhou mingled with the Qiang people, in all these stages, the advanced Shang bronze culture constantly imparted its influence on the Zhou. The Qi area was the region in all these influences would come to fruition. The contact among the proto-Zhou, the native Shaanxi Longshan, the Qiang, King Wu maintained the old capital for ceremonial purposes but constructed a new one for his palace and administration nearby at Hao. Although Wus early death left a young and inexperienced heir, the Duke of Zhou assisted his nephew King Cheng in consolidating royal power. Wary of the Duke of Zhous increasing power, the Three Guards, Zhou princes stationed on the eastern plain, to maintain Zhou authority over its greatly expanded territory and prevent other revolts, he set up the fengjian system

Metal
–
A metal is a material that is typically hard, opaque, shiny, and has good electrical and thermal conductivity. Metals are generally malleable—that is, they can be hammered or pressed permanently out of shape without breaking or cracking—as well as fusible and ductile, about 91 of the 118 elements in the periodic table are metals, the others are nonmetals or metalloids. Some elements appear in both metallic and non-metallic forms, astrophysicists use the term metal to collectively describe all elements other than hydrogen and helium, the simplest two, in a star. The star fuses smaller atoms, mostly hydrogen and helium, to larger ones over its lifetime. In that sense, the metallicity of an object is the proportion of its matter made up of all chemical elements. Many elements and compounds that are not normally classified as metals become metallic under high pressures, the atoms of metallic substances are typically arranged in one of three common crystal structures, namely body-centered cubic, face-centered cubic, and hexagonal close-packed. In bcc, each atom is positioned at the center of a cube of eight others, in fcc and hcp, each atom is surrounded by twelve others, but the stacking of the layers differs. Some metals adopt different structures depending on the temperature, atoms of metals readily lose their outer shell electrons, resulting in a free flowing cloud of electrons within their otherwise solid arrangement. This provides the ability of metallic substances to easily transmit heat, while this flow of electrons occurs, the solid characteristic of the metal is produced by electrostatic interactions between each atom and the electron cloud. This type of bond is called a metallic bond, Metals are usually inclined to form cations through electron loss, reacting with oxygen in the air to form oxides over various timescales. Examples,4 Na + O2 →2 Na2O2 Ca + O2 →2 CaO4 Al +3 O2 →2 Al2O3, the transition metals are slower to oxidize because they form a passivating layer of oxide that protects the interior. Others, like palladium, platinum and gold, do not react with the atmosphere at all, some metals form a barrier layer of oxide on their surface which cannot be penetrated by further oxygen molecules and thus retain their shiny appearance and good conductivity for many decades. The oxides of metals are generally basic, as opposed to those of nonmetals, exceptions are largely oxides with very high oxidation states such as CrO3, Mn2O7, and OsO4, which have strictly acidic reactions. Painting, anodizing or plating metals are good ways to prevent their corrosion, however, a more reactive metal in the electrochemical series must be chosen for coating, especially when chipping of the coating is expected. Water and the two form an electrochemical cell, and if the coating is less reactive than the coatee. Metals in general have high conductivity, high thermal conductivity. Typically they are malleable and ductile, deforming under stress without cleaving, in terms of optical properties, metals are shiny and lustrous. Sheets of metal beyond a few micrometres in thickness appear opaque, although most metals have higher densities than most nonmetals, there is wide variation in their densities, lithium being the least dense solid element and osmium the densest

Gourd
–
A gourd is a plant of the family Cucurbitaceae, particularly Cucurbita and Lagenaria or the fruit of the two genera of Bignoniaceae calabash tree, Crescentia and Amphitecna. The term refers to a number of species and subspecies, many with hard shells, likely one of the earliest domesticated types of plants, subspecies of the bottle gourd, Lagenaria siceraria, have been discovered in archaeological sites dating from as early as 13,000 BC. Gourds have had numerous uses throughout history, including as tools, musical instruments, objects of art, film, gourd is occasionally used to describe crop plants in the family Cucurbitaceae, like pumpkins, cucumbers, squash, luffa, and melons. More specifically, gourd refers to the fruits of plants in the two Cucurbitaceae genera Lagenaria and Cucurbita, or also to their hollow, dried-out shell, a gourd can also have a hard shell when dehydrated. There are many different gourds worldwide, the main plants referred to as gourds include several species from the Cucurbita genus, Crescentia cujete and Lagenaria siceraria. The bitter melon/balsam apple/balsam pear is also referred to as a gourd. L. siceraria was brought to Europe and the Americas very early in history, being found in Peruvian archaeological sites dating from 13,000 to 11,000 BC and Thailand sites from 11,000 to 6,000 BC. The gourds found in the Americas appear to have come from the Asian subspecies, very early in history, a new study now indicates Africa. The archaeological and DNA records show it likely that the gourd was among the first domesticated species, gourds continued to be used throughout history, in almost every culture throughout the world. European contact in North America found extensive use, including the use of bottle gourds as birdhouses to attract purple martins. Almost every culture had musical instruments made of gourds, including drums, stringed instruments common to Africa and wind instruments and these include Teasle gourd, Spine gourd, Sweet gourd, balsam apple and Momordica sahyadrica. Cultures from arid regions often associated gourds with water, and they appear in creation myths. Since the beginning of their history, they have had a multitude of uses, including food, kitchen tools, toys, musical instruments and decoration. Today, gourds are used for a wide variety of crafts, including jewelry, furniture, dishes, utensils. The Chinese developed a technique of tying a two-part mould around young gourds, or a part of them, so that the gourd grew into the mould, shaped gourds had various decorative uses, especially as boxes, bottles and other containers. The Luffa gourds, Luffa aegyptiaca and Luffa acutangula, have been used throughout recent history as scrubbing sponge and this is prepared by removing the skin and pulp from the gourd, and bleaching the fibers. A güiro is a Latin American percussion instrument made from a gourd, maracas are percussion instruments often made from gourds. A sitar is a stringed instrument, parts of which are made from gourds

Clay
–
Clay is a fine-grained natural rock or soil material that combines one or more clay minerals with traces of metal oxides and organic matter. Geologic clay deposits are composed of phyllosilicate minerals containing variable amounts of water trapped in the mineral structure. Clays are plastic due to water content and become hard, brittle. Depending on the content in which it is found, clay can appear in various colours from white to dull grey or brown to deep orange-red. Although many naturally occurring deposits include both silts and clay, clays are distinguished from other fine-grained soils by differences in size, silts, which are fine-grained soils that do not include clay minerals, tend to have larger particle sizes than clays. There is, however, some overlap in size and other physical properties. The distinction between silt and clay varies by discipline, geologists and soil scientists usually consider the separation to occur at a particle size of 2 µm, sedimentologists often use 4–5 μm, and colloid chemists use 1 μm. Geotechnical engineers distinguish between silts and clays based on the plasticity properties of the soil, as measured by the soils Atterberg limits, ISO14688 grades clay particles as being smaller than 2 μm and silt particles as being larger. These solvents, usually acidic, migrate through the rock after leaching through upper weathered layers. In addition to the process, some clay minerals are formed through hydrothermal activity. There are two types of deposits, primary and secondary. Primary clays form as residual deposits in soil and remain at the site of formation, secondary clays are clays that have been transported from their original location by water erosion and deposited in a new sedimentary deposit. Clay deposits are associated with very low energy depositional environments such as large lakes. Depending on the source, there are three or four main groups of clays, kaolinite, montmorillonite-smectite, illite, and chlorite. Chlorites are not always considered to be a clay, sometimes being classified as a group within the phyllosilicates. There are approximately 30 different types of clays in these categories. Varve is clay with visible annual layers, which are formed by deposition of those layers and are marked by differences in erosion. This type of deposit is common in glacial lakes

Leather
–
Leather is a durable and flexible material created by tanning animal rawhide and skin, often cattle hide. It can be produced at manufacturing scales ranging from cottage industry to heavy industry, people use leather to make various goods—including clothing, bookbinding, leather wallpaper, and as a furniture covering. It is produced in a variety of types and styles. Several tanning processes transform hides and skins into leather, Chrome-tanned leather, invented in 1858, is tanned using chromium sulfate and it is more supple and pliable than vegetable-tanned leather and does not discolor or lose shape as drastically in water as vegetable-tanned. It is also known as wet-blue for its color derived from the chromium, more exotic colors are possible when using chrome tanning. The chrome tanning method usually only takes a day to finish, and it is reported that chrome-tanned leather adds up to 80% of the global leather supply. Vegetable-tanned leather is tanned using tannins and other found in different vegetable matter, such as tree bark prepared in bark mills, wood, leaves, fruits. It is supple and brown in color, with the exact shade depending on the mix of chemicals and it is the only form of leather suitable for use in leather carving or stamping. Vegetable-tanned leather is not stable in water, it tends to discolor, so if left to soak and then dried it shrinks, in hot water, it shrinks drastically and partly congeals—becoming rigid, and eventually brittle. Boiled leather is an example of this, where the leather has been hardened by being immersed in hot water, historically, it was occasionally used as armour after hardening, and it has also been used for book binding. Aldehyde-tanned leather is tanned using glutaraldehyde or oxazolidine compounds and this is the leather that most tanners refer to as wet-white leather due to its pale cream or white color. It is the type of chrome-free leather, often seen in shoes for infants. Formaldehyde tanning is another aldehyde tanning method, brain-tanned leathers fall into this category, and are exceptionally water absorbent. Brain tanned leathers are made by a process that uses emulsified oils, often those of animal brains such as deer, cattle. They are known for their softness and washability. Chamois leather also falls into the category of aldehyde tanning, and like brain tanning, produces a porous, chamois leather is made using marine oils that oxidize easily to produce the aldehydes that tan the leather to color it. Rose-tanned leather is a variation of oil tanning and brain tanning. Rose-tanned leather tanned leaves a powerful rose fragrance even years from when it is manufactured and it has been called the most valuable leather on earth, but this is mostly due to the high cost of rose otto and its labor-intensive tanning process

Rites of Zhou
–
The Rites of Zhou, originally known as Officers of Zhou is actually a work on bureaucracy and organizational theory. It was renamed by Liu Xin to differentiate it from a chapter in the Book of History by the same name. To replace a lost work, it was included along with the Book of Rites and the Etiquette and Ceremonial – becoming one of three ancient ritual texts listed among the classics of Confucianism. The book appeared in the middle of the 2nd century BC, when it was found and included in the collection of Old Texts in the library of Prince Liu De and its first editor was Liu Xin, who credited it to the Duke of Zhou. Tradition since at least the Song dynasty continued this attribution, with the claim that Liu Xins edition was the final one. In the 12th century, it was given recognition by being placed among the Five Classics as a substitute for the long-lost sixth work. In the late 19th and early 20th centuries, following Kang Youwei, currently, a few holdouts continue to insist on a Western Zhou date while the majority follow Qian Mu and Gu Jiegang in assigning the work to about the 3rd century BC. The work consists mainly of lists of Zhou dynasty bureaucrats, stating what the function of each office is. Sometimes though the mechanical listing is broken off by pieces of philosophical exposition on how a given office contributes to social harmony, the division of chapters follows the six departments of the Zhou dynasty government. The bureaucrats within a department come in five ranks, minister, councilor, senior clerk, middle clerk, there is only one minister per department -the department head-, but the other four ranks all have multiple holders spread across various specific professions. A part of the Winter Offices, the Record of Trades, contains important information on technology, architecture, city planning, a passage records that, The master craftsman constructs the state capital. He makes a square nine li on one side, each side has three gates, within the capital are nine north-south and nine east-west streets. The north-south streets are nine tracks in width.

Zuo zhuan
–
It comprises thirty chapters covering a period from 722 to 468 BC, and focuses mainly on political, diplomatic, and military affairs from that era. The Zuo zhuan was, for centuries, the primary text through which the Chinese gained an understanding of their ancient history. The Zuo zhuan is the source of more Chinese sayings and idioms than any other classical work, notwithstanding its prominent position throughout Chinese history as the paragon of Classical Chinese prose, little is known of the Zuo zhuans creation and early history. Its earliest known mention appears in Sima Qians Records of the Grand Historian, the first of Chinas twenty-four dynastic histories, which was completed about 94 BC. Other than his mention in the Analects, nothing is concretely known of Zuo Qiumings life or identity. This traditional assumption that the titles Master Zuo refers to the Zuo Qiuming of the Analects is not based on any specific evidence, in 1792, the scholar Yao Nai wrote, The text did not come from one person. There were repeated accretions and additions, with those of Wu Qi, in the early 1930s, the French Sinologist Henri Maspero performed a detailed textual study of the issue, concluding the Han dynasty forgery theory to be untenable. While Lius hypothesis that the Zuo zhuan was not originally an Annals commentary has been generally accepted, four of the fragments date to the Six Dynasties period, while the other two date to the early Tang dynasty. The oldest known complete Zuo zhuan manuscript is the ancient manuscript scroll preserved at the Kanazawa Bunko Museum in Yokohama, the Zuo zhuan recounts the major political, military, and social events of the Spring and Autumn period, and is famous for its dramatic power and realistic details. The Zuo zhuan originally contained only its content, without any content from or references to the Spring. In the 3rd century AD, the Chinese scholar Du Yu intercalated the Annals into the Zuo zhuan and its overarching theme is that haughty, evil, and stupid individuals generally bring disaster upon themselves, while those who are good, wise, and humble are usually justly rewarded. The Confucian principle of ritual propriety or ceremony is seen as governing all actions, including war, however, the observance of li is never shown as guaranteeing victory, and the Zuo zhuan includes many examples of the good and innocent suffering senseless violence. Much of the Zuo zhuans status as a literary masterpiece stems from its realistic portrayal of a turbulent era marked by violence, political strife, intrigues. The narratives of the Zuo zhuan are highly didactic in nature, several of the Zuo zhuans most famous sections are those dealing with critical historical battles, such as the Battle of Chengpu and the Battle of Bi. The Battle of Chengpu, the first of the Zuo zhuans great battles, on one side were the troops of the powerful State of Chu, from what was then far southern China, led by the Chu prime minister Cheng Dechen. They were opposed by the armies of the State of Jin, led by Chonger, Duke of Jin, one of the most prominent, Chu suffered a disastrous defeat in the battle itself, and it resulted in Chonger being named Hegemon of the various states. Several of the most notable passages in the Zuo zhuan describe succession crises, the best known of these stories is that of Duke Zhuang of Zheng, who ruled the State of Zheng from 743 to 701 BC. Duke Zhuang was born in a manner that startled his mother, a number of Zuo zhuan anecdotes end with brief moral comments or verdicts that are attributed to either Confucius or an unnamed junzi

Tso Chiu-Ming
–
Zuo Qiuming was a Chinese writer and contemporary of Confucius who lived in the State of Lu during the Spring and Autumn period of ancient China. It is uncertain whether his surname is Zuo or Zuoqiu, therefore the name may be written as Zuo Qiuming or Zuoqiu Ming, the influential historical text Zuo Zhuan is traditionally attributed to him. He is also possibly a contributor to Guoyu, one tradition, according to the Records of the Grand Historian, holds that he was blind. Zuo is quoted in the Analects to be a paragon of the conduct of Confucius, the Master said, Fine words, an insinuating appearance, and excessive respect - Zuo Qiuming was ashamed of them. I also am ashamed of them, to conceal resentment against a person, and appear friendly with him - Zuo Qiuming was ashamed of such conduct

Ming dynasty
–
The Ming dynasty was the ruling dynasty of China – then known as the Empire of the Great Ming – for 276 years following the collapse of the Mongol-led Yuan dynasty. The Ming, described by some as one of the greatest eras of orderly government, although the primary capital of Beijing fell in 1644 to a rebellion led by Li Zicheng, regimes loyal to the Ming throne – collectively called the Southern Ming – survived until 1683. He rewarded his supporters and employed them as a counterweight against the Confucian scholar-bureaucrats. One, Zheng He, led seven enormous voyages of exploration into the Indian Ocean as far as Arabia, the rise of new emperors and new factions diminished such extravagances, the capture of the Zhengtong Emperor during the 1449 Tumu Crisis ended them completely. The imperial navy was allowed to fall into disrepair while forced labor constructed the Liaodong palisade, haijin laws intended to protect the coasts from Japanese pirates instead turned many into smugglers and pirates themselves. The growth of Portuguese, Spanish, and Dutch trade created new demand for Chinese products and produced an influx of Japanese. This abundance of specie remonetized the Ming economy, whose money had suffered repeated hyperinflation and was no longer trusted. While traditional Confucians opposed such a prominent role for commerce and the newly rich it created, combined with crop failure, floods, and epidemic, the dynasty collapsed before the rebel leader Li Zicheng, who was defeated by the Manchu-led Eight Banner armies who founded the Qing dynasty. The Mongol-led Yuan dynasty ruled before the establishment of the Ming dynasty, consequently, agriculture and the economy were in shambles, and rebellion broke out among the hundreds of thousands of peasants called upon to work on repairing the dykes of the Yellow River. A number of Han Chinese groups revolted, including the Red Turbans in 1351, the Red Turbans were affiliated with the White Lotus, a Buddhist secret society. Zhu Yuanzhang was a peasant and Buddhist monk who joined the Red Turbans in 1352. In 1356, Zhus rebel force captured the city of Nanjing, with the Yuan dynasty crumbling, competing rebel groups began fighting for control of the country and thus the right to establish a new dynasty. In 1363, Zhu Yuanzhang eliminated his archrival and leader of the rebel Han faction, Chen Youliang, in the Battle of Lake Poyang, arguably the largest naval battle in history. Known for its ambitious use of ships, Zhus force of 200,000 Ming sailors were able to defeat a Han rebel force over triple their size, claimed to be 650. The victory destroyed the last opposing rebel faction, leaving Zhu Yuanzhang in uncontested control of the bountiful Yangtze River Valley, Zhu Yuanzhang took Hongwu, or Vastly Martial, as his era name. Hongwu made an effort to rebuild state infrastructure. He built a 48 km long wall around Nanjing, as well as new palaces, Hongwu organized a military system known as the weisuo, which was similar to the fubing system of the Tang dynasty. With a growing suspicion of his ministers and subjects, Hongwu established the Jinyiwei, some 100,000 people were executed in a series of purges during his rule

Zhu Zaiyu

Zhu Zaiyu was a prince of the Ming dynasty of China. In 1584, Prince Zhu innovatively described the equal temperament via accurate mathematical calculation, Zhu was born in Qinyang, Henan Province to an aristocratic family, the sixth-generation descendant of the Hongxi Emperor, the fourth emperor of the Ming Dynasty. Zhu inherited the title the Prince of Zheng in 1593, on the emperors order, he was granted a new princely title in 1606, the year he delivered a set of ten musicological treatises to the court, establishing his scholarly merit. His posthumous name was 鄭端靖世子 Zhu wrote on music theory and temperament, music history, dance and dance music, three music theory works in particular are associated with the ideas of equal temperament, the「律學新說」, 「律呂精義」, and 「算學新說」. His work has described as the crowning achievement of two millennia of acoustical experiment and research and he is described as one of the most important historians of his nations music.

Rhythm
–
Rhythm generally means a movement marked by the regulated succession of strong and weak elements, or of opposite or different conditions. In the performance arts, rhythm is the timing of events on a scale, of musical sounds and silences that occur over time, of the steps of a dance, or the meter of spoken language. In some performing arts, such as hip hop music, the delivery of the lyrics is one of the most important elements of the style. Rhythm may also refer to visual presentation, as timed movement through space, in recent years, rhythm and meter have become an important area of research among music scholars. Recent work in these areas includes books by Maury Yeston, Fred Lerdahl and Ray Jackendoff, Jonathan Kramer, Christopher Hasty, Godfried Toussaint, William Rothstein, and Joel Lester. In Thinking and Destiny, Harold W. Percival defined rhythm as the character and meaning of thought expressed through the measure or movement in sound or form, or by written signs or words. In his television series How Music Works, Howard Goodall presents theories that human rhythm recalls the regularity with which we walk, other research suggests that it does not relate to the heartbeat directly, but rather the speed of emotional affect, which also influences heartbeat. Yet other researchers suggest that certain features of human music are widespread. The perception and abstraction of rhythmic measure is the foundation of human instinctive musical participation, Joseph Jordania recently suggested that the sense of rhythm was developed in the early stages of hominid evolution by the forces of natural selection. Plenty of animals walk rhythmically and hear the sounds of the heartbeat in the womb, some types of parrots can know rhythm. There is not a report of an animal being trained to tap, peck. For this reason, the fast-transient sounds of percussion instruments lend themselves to the definition of rhythm, Musical cultures that rely upon such instruments may develop multi-layered polyrhythm and simultaneous rhythms in more than one time signature, called polymeter. Such are the cross-rhythms of Sub-Saharan Africa and the interlocking kotekan rhythms of the gamelan, for information on rhythm in Indian music see Tala. For other Asian approaches to rhythm see Rhythm in Persian music, Rhythm in Arabian music and Usul—Rhythm in Turkish music and this consists of a series of identical yet distinct periodic short-duration stimuli perceived as points in time. It is currently most often designated as a crotchet or quarter note in western notation, faster levels are division levels, and slower levels are multiple levels. Rhythms of recurrence arise from the interaction of two levels of motion, the faster providing the pulse and the slower organizing the beats into repetitive groups. Once a metric hierarchy has been established, we, as listeners, a durational pattern that synchronises with a pulse or pulses on the underlying metric level may be called a rhythmic unit. A rhythmic gesture is any pattern that, in contrast to the rhythmic unit

Audio editing software
–
Audio editing software is software which allows editing and generating of audio data. Audio editing software can be implemented completely or partly as library, as computer application, wave Editors are digital audio editors and there are many sources of software available to perform this function. Most can edit music, apply effects and filters, adjust stereo channels etc, Editors designed for use with music typically allow the user to do the following, The ability to import and export various audio file formats for editing. Audio editors may process the audio data non-destructively in real-time, or destructively as a process, or a hybrid with some real-time effects. Destructive editing modifies the data of the audio file, as opposed to just editing its playback parameters. Destructive editors are also known as sample editors, destructive editing applies edits and processing directly to the audio data, changing the data immediately. If, for example, part of a track is deleted, real-time editing does not apply changes immediately, but applies edits and processing on the fly during playback. If, for example, part of a track is deleted, the audio data is not actually removed from the track. In graphical editors, all changes to the audio is usually visible immediately as the waveform is updated to match the audio data. The number of effects that may be applied is virtually unlimited, editing is usually precise down to exact sample intervals. Effects may be applied to a precisely specified selected region, mixing down or exporting the edited audio is usually relatively quick as little additional processing is required. Once an effect has been applied, it cannot usually be changed and this is usually mitigated by the ability to undo the last performed action. Typically a destructive audio editor will maintain many levels of history so that multiple actions may be undone in the reverse order that they were applied. Edits can only be undone in the order that they were applied. Effects can usually be adjusted during playback, or at any other time, edits may be undone or adjusted at any time in any order. Multiple effects and edits may be stacked so that they are applied to the audio as an effect chain, a stack of effects may be changed so that effects are applied in a different order, or effects inserted or removed from the chain. Some real-time editors support effect automation so that changes to effect parameters may be programmed to occur at specified times during audio playback, the waveform does not usually show the effect of processing until the audio has been mixed-down or bounced to another track. The number of effects that may be applied is limited by the processing power of the computer or editing hardware

Effects unit
–
An effects unit or pedal is an electronic or digital device that alters how a musical instrument or other audio source sounds. In the 2010s, most effects use solid state electronics and/or computer chips, some vintage effects units from the 1930s to the 1970s and modern reissues of these effects use mechanical components as well or vacuum tubes. Musicians, audio engineers and record producers use effects units during live performances or in the studio, typically with electric guitar, electronic keyboard, while guitar effects are most frequently used with electric or electronic instruments, effects can also be used with acoustic instruments, drums and vocals. Rackmounted or audio console-integrated reverb effects are used with vocals in live sound and sound recording. Examples of common units include wah-wah pedals, fuzzboxes and reverb units. A stompbox or pedal is a metal or plastic box placed on the floor in front of the musician and connected to the instrument. Pedals are usually the least expensive format, a rackmount device mounts on a standard 19-inch equipment rack and usually contains several types of effects. Rackmount effects typically have buttons and/or knobs on the face of the chassis for controlling the effects, an effects unit is also called an effect box, effects device, effects processor or simply effects. In audio engineer parlance, a signal without effects is dry, the abbreviation F/X or FX is sometimes used. A pedal-style unit may be called a box, stompbox. When a musician has multiple effects in a rack mounted road case, Effects units are available in a variety of formats or form factors. Stompboxes are usually the smallest, least expensive, and most rugged effects units, rackmount devices are generally more expensive and offer a wider range of functions. An effects unit can consist of analog or digital circuitry or a combination of the two, during a live performance, the effect is plugged into the electrical signal path of the instrument. In the studio, the instrument or other sound-sources auxiliary output is patched into the effect, form factors are part of a studio or musicians outboard gear. Stompboxes are small plastic or metal chassis which usually lie on the floor or in a pedalboard to be operated by the users feet, pedals are often rectangle-shaped, but there are a range of other shapes. Typical simple stompboxes have a single footswitch, one to three potentiometers for controlling the effect, and a single LED that indicates if the effect is on, depending on the type of pedal, the potentiometers may control different parameters of the effect. For a chorus effect, for example, the knobs may control the depth, some pedals have two knobs stacked on top of each other, enabling the unit to provide two knobs per single knob space. An effects chain or signal chain is formed by connecting two or more stompboxes, effect chains are typically created between the guitar and the amp or between the preamplifier and the power amp

Ancient Greece
–
Ancient Greece was a civilization belonging to a period of Greek history from the Greek Dark Ages of the 12th-9th centuries BC to the end of antiquity. Immediately following this period was the beginning of the Early Middle Ages and this was followed by the period of Classical Greece, an era that began with the Greco-Persian Wars, lasting from the 5th to 4th centuries BC. Due to the conquests by Alexander the Great of Macedonia, Hellenistic civilization flourished from Central Asia to the end of the Mediterranean Sea. Classical Greek culture, especially philosophy, had a influence on ancient Rome. For this reason Classical Greece is generally considered to be the culture which provided the foundation of modern Western culture and is considered the cradle of Western civilization. Classical Antiquity in the Mediterranean region is considered to have begun in the 8th century BC. Classical Antiquity in Greece is preceded by the Greek Dark Ages and this period is succeeded, around the 8th century BC, by the Orientalizing Period during which a strong influence of Syro-Hittite, Jewish, Assyrian, Phoenician and Egyptian cultures becomes apparent. The end of the Dark Ages is also dated to 776 BC. The Archaic period gives way to the Classical period around 500 BC, Ancient Periods Astronomical year numbering Dates are approximate, consult particular article for details The history of Greece during Classical Antiquity may be subdivided into five major periods. The earliest of these is the Archaic period, in which artists made larger free-standing sculptures in stiff, the Archaic period is often taken to end with the overthrow of the last tyrant of Athens and the start of Athenian Democracy in 508 BC. It was followed by the Classical period, characterized by a style which was considered by observers to be exemplary, i. e. classical, as shown in the Parthenon. This period saw the Greco-Persian Wars and the Rise of Macedon, following the Classical period was the Hellenistic period, during which Greek culture and power expanded into the Near and Middle East. This period begins with the death of Alexander and ends with the Roman conquest, Herodotus is widely known as the father of history, his Histories are eponymous of the entire field. Herodotus was succeeded by authors such as Thucydides, Xenophon, Demosthenes, Plato, most of these authors were either Athenian or pro-Athenian, which is why far more is known about the history and politics of Athens than those of many other cities. Their scope is limited by a focus on political, military and diplomatic history, ignoring economic. In the 8th century BC, Greece began to emerge from the Dark Ages which followed the fall of the Mycenaean civilization, literacy had been lost and Mycenaean script forgotten, but the Greeks adopted the Phoenician alphabet, modifying it to create the Greek alphabet. The Lelantine War is the earliest documented war of the ancient Greek period and it was fought between the important poleis of Chalcis and Eretria over the fertile Lelantine plain of Euboea. Both cities seem to have suffered a decline as result of the long war, a mercantile class arose in the first half of the 7th century BC, shown by the introduction of coinage in about 680 BC

Porphyry (philosopher)
–
Porphyry of Tyre was a Neoplatonic philosopher who was born in Tyre, in the Roman Empire. He edited and published the Enneads, the collection of the work of his teacher Plotinus. His commentary on Euclids Elements was used as a source by Pappus of Alexandria and he also wrote many works himself on a wide variety of topics. His Isagoge, or Introduction, is an introduction to logic and philosophy, under Longinus he studied grammar and rhetoric. In 262 he went to Rome, attracted by the reputation of Plotinus, at one point he became suicidal. On the advice of Plotinus he went to live in Sicily for five years to recover his mental health, on returning to Rome, he lectured on philosophy and completed an edition of the writings of Plotinus together with a biography of his teacher. Iamblichus is mentioned in ancient Neoplatonic writings as his pupil, the two men differed publicly on the issue of theurgy. In his later years, he married Marcella, a widow with seven children, little more is known of his life, and the date of his death is uncertain. Porphyry is best known for his contributions to philosophy, in medieval textbooks, the all-important Arbor porphyriana illustrates his logical classification of substance. To this day, taxonomy benefits from concepts in Porphyrys Tree, the Introduction was translated into Arabic by Abd-Allāh Ibn al-Muqaffaʿ from a Syriac version. With the Arabicized name Isāghūjī it long remained the standard introductory text in the Muslim world and influenced the study of theology, philosophy, grammar. Besides the adaptations and epitomes of this work, many independent works on logic by Muslim philosophers have been entitled Isāghūjī, Porphyrys discussion of accident sparked a long-running debate on the application of accident and essence. There is debate as to whether it was written in his youth or closer in time to the persecutions of Christians under Diocletian, whether or not Porphyry was the pagan philosopher opponent in Lactantius Divine Institutes, written at the time of the persecutions, has long been discussed. The fragments of the Philosophy from Oracles are only quoted by Christians, especially Eusebius, Theodoret, Augustine, the fragments contain oracles identifying proper sacrificial procedure, the nature of astrological fate, and other topics relevant for Greek and Roman religion in the third century. Whether this work contradicts his treatise defending vegetarianism, which warned the philosopher to avoid animal sacrifice, is disputed among scholars. During his retirement in Sicily, Porphyry wrote Against the Christians which consisted of fifteen books, Porphyry acknowledged Jesus Christ only as an outstanding philosopher. Some thirty Christian apologists, such as Methodius, Eusebius, Apollinaris, Augustine, Jerome, in fact, everything known about Porphyry’s arguments is found in these refutations, largely because Theodosius II ordered every copy burned in A. D.435 and again in 448. Porphyry became one of the most able pagan adversaries of Christianity of his day and his aim was not to disprove the substance of Christianity’s teachings but rather the records within which the teachings are communicated

Guitar
–
The guitar is a musical instrument classified as a fretted string instrument with anywhere from four to 18 strings, usually having six. The sound is projected either acoustically, using a wooden or plastic and wood box, or through electrical amplifier. It is typically played by strumming or plucking the strings with the fingers, the guitar is a type of chordophone, traditionally constructed from wood and strung with either gut, nylon or steel strings and distinguished from other chordophones by its construction and tuning. There are three types of modern acoustic guitar, the classical guitar, the steel-string acoustic guitar, and the archtop guitar. The tone of a guitar is produced by the strings vibration, amplified by the hollow body of the guitar. The term finger-picking can also refer to a tradition of folk, blues, bluegrass. The acoustic bass guitar is an instrument that is one octave below a regular guitar. Early amplified guitars employed a body, but a solid wood body was eventually found more suitable during the 1960s and 1970s. As with acoustic guitars, there are a number of types of guitars, including hollowbody guitars, archtop guitars and solid-body guitars. The electric guitar has had a influence on popular culture. The guitar is used in a variety of musical genres worldwide. It is recognized as an instrument in genres such as blues, bluegrass, country, flamenco, folk, jazz, jota, mariachi, metal, punk, reggae, rock, soul. The term is used to refer to a number of chordophones that were developed and used across Europe, beginning in the 12th century and, later, in the Americas. The modern word guitar, and its antecedents, has applied to a wide variety of chordophones since classical times. Many influences are cited as antecedents to the modern guitar, at least two instruments called guitars were in use in Spain by 1200, the guitarra latina and the so-called guitarra morisca. The guitarra morisca had a back, wide fingerboard. The guitarra Latina had a sound hole and a narrower neck. By the 14th century the qualifiers moresca or morisca and latina had been dropped, and it had six courses, lute-like tuning in fourths and a guitar-like body, although early representations reveal an instrument with a sharply cut waist

Violin
–
The violin is a wooden string instrument in the violin family. It is the smallest and highest-pitched instrument in the family in regular use, smaller violin-type instruments are known, including the violino piccolo and the kit violin, but these are virtually unused in the 2010s. The violin typically has four strings tuned in fifths, and is most commonly played by drawing a bow across its strings. Violins are important instruments in a variety of musical genres. They are most prominent in the Western classical tradition and in varieties of folk music. They are also used in genres of folk including country music and bluegrass music. Electric violins are used in forms of rock music, further. The violin is sometimes called a fiddle, particularly in Irish traditional music and bluegrass. The violin was first known in 16th-century Italy, with further modifications occurring in the 18th and 19th centuries. In Europe it served as the basis for stringed instruments used in classical music, the viola. According to their reputation, the quality of their sound has defied attempts to explain or equal it, many of these trade instruments were formerly sold by Sears, Roebuck and Co. and other mass merchandisers. A person who makes or repairs violins is called a luthier or violinmaker, the parts of a violin are usually made from different types of wood and on the use of a pickup and an amplifier and speaker). Violins can be strung with gut, Perlon or other synthetic, the earliest stringed instruments were mostly plucked. Similar and variant types were probably disseminated along East-West trading routes from Asia into the Middle East, the first makers of violins probably borrowed from various developments of the Byzantine lira. These included the rebec, the Arabic rebab, the vielle, the earliest pictures of violins, albeit with three strings, are seen in northern Italy around 1530, at around the same time as the words violino and vyollon are seen in Italian and French documents. One of the earliest explicit descriptions of the instrument, including its tuning, is from the Epitome musical by Jambe de Fer, by this time, the violin had already begun to spread throughout Europe. The violin proved very popular, both among street musicians and the nobility, the French king Charles IX ordered Andrea Amati to construct 24 violins for him in 1560, one of these noble instruments, the Charles IX, is the oldest surviving violin. The Messiah or Le Messie made by Antonio Stradivari in 1716 remains pristine and it is now located in the Ashmolean Museum of Oxford

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

Sheet music
–
Sheet music is a handwritten or printed form of music notation that uses modern musical symbols to indicate the pitches, rhythms and/or chords of a song or instrumental musical piece. The first printed sheet music made with a press was made in 1473. Sheet music is the form in which Western classical music is notated so that it can be learned and performed by solo singers or instrumentalists or musical ensembles. Many forms of traditional and popular Western music are commonly learned by singers and musicians by ear, Score is a common alternative term for sheet music, and there are several types of scores, as discussed below. Sheet music from the 20th and 21st century typically indicates the title of the song or composition on a page or cover, or on the top of the first page. If the song or piece is from a movie, Broadway musical, or opera, if the songwriter or composer is known, her or his name is typically indicated along with the title. Black market sheet music, such as illegal jazz fake books may or may not indicate the songwriter or composer, the type of musical notation varies a great deal by genre or style of music. In most classical music, the melody and accompaniment parts are notated on the lines of a staff using round note heads, the lyrics, if present, are written near the melody notes. However, music from the Baroque music era or earlier eras may have neither a tempo marking nor a dynamic indication. The singers and musicians of that era were expected to know what tempo and loudness to play or sing a song or piece due to their musical experience. In the contemporary music era, and in some cases before, composers often used their native language for tempo indications. These conventions of music notation, and in particular the use of English tempo instructions, are also used for sheet music versions of 20th. Popular music songs often indicate both the tempo and genre, slow blues or uptempo rock, pop songs often contain chord names above the staff using letter names, so that an acoustic guitarist or piano player can improvise a chordal accompaniment. In other styles of music, different musical notation methods may be used, in jazz, while most professional performers can read classical-style notation, many jazz tunes are notated using chord charts, which indicate the chord progression of a song and its form. Like popular music songs, jazz tunes often indicate both the tempo and genre, slow blues or fast bop, professional country music session musicians typically use music notated in the Nashville Number System, which indicates the chord progression using numbers. Chord charts using letter names, numbers, or Roman numerals are widely used for notating music by blues, R&B, rock music. Many guitar players and electric bass players learn songs and note tunes using tablature, tab is widely used rock music and heavy metal guitarists. Singers in many music styles learn a song using only a lyrics sheet

Serpent (instrument)
–
The serpent is the bass wind instrument, descended from the cornett, and a distant ancestor of the tuba, with a mouthpiece like a brass instrument but side holes like a woodwind. It is usually a long cone bent into a snakelike shape, the serpent is closely related to the cornett, although it is not part of the cornett family, due to the absence of a thumb hole. It is generally out of wood, with walnut being a particularly popular choice. The outside is covered with brown or black leather. The serpents range varies according to the instrument and the player, the serpent usually has six holes, which are ordered in two groups of three. On early models, the fingerholes were keyless, like those of a recorder, however, later models added keys as on a clarinet, although they were for additional holes, while the original holes remained unkeyed, and are covered or uncovered directly by the players fingers. The serpent player also has a unique right-hand finger position, in that the finger may be further down the tube towards the bell than the other fingers of that hand. Later, players began to hold the instrument horizontally, the instrument is claimed to have been invented by Canon Edmé Guillaume in 1590 in Auxerre, France, and was first used to strengthen the sound of choirs in plainchant. This date for the invention of the serpent did not appear until 1743, herbert Heyde asserts the serpent evolved from a type of bass cornetto and was invented in Italy in the 16th century. Around the middle of the 18th century, it began to appear in bands and orchestras. Richard Wagner used the serpent in place of the bassoon in his opera Rienzi. After that the serpent dropped off in popularity for a period of time, bernard Herrmann used a serpent in the scores of White Witch Doctor and Journey to the Center of the Earth, as did Jerry Goldsmith in his score for Alien. In the 1970s, instrument-maker Christopher Monk began playing, and later making Serpents, since then, the instrument has undergone a revival of sorts. In 1987, Simon Proctor wrote the first concerto for the instrument, the Serpent Concerto was first performed on October 21,1989 at the First International Serpent Festival with serpent soloist Alan Lumsden. In 2008, Douglas Yeo premiered another serpent concerto, Old Dances in New Shoes by Washington D. C. –based composer Gordon Bowie, with the Boston Classical Orchestra, conducted by Steven Lipsitt. On July 14,2012 in the Monopoli Conservatory of Music was performed the premiere of a Serpent Concerto with the title Diversita. The soundtrack by Austin Wintory of the PlayStation 3 videogame Journey uses a serpent as one of the five soloists, there are two main types of serpent, curved and straight/upright. Within the curved style, there are two variations, Church and Military, the Church serpent is the original type, popularized in France, and is distinguished by gentle, sweeping curves and little metal reinforcements

Keyboard instrument
–
A keyboard instrument is a musical instrument played using a keyboard. The most common of these are the piano, organ, and various keyboards, including synthesizers. Other keyboard instruments include celestas, which are struck idiophones operated by a keyboard, and carillons, today, the term keyboard often refers to keyboard-style synthesizers. Another important use of the keyboard is in historical musicology. Particularly in the 18th century, the harpsichord, the clavichord, and the piano were in competition. Hence in a phrase like Mozart excelled as a player the word keyboard is usefully noncommittal. The earliest known keyboard instrument was the Ancient Greek hydraulis, a type of pipe organ, the keys were likely balanced and could be played with a light touch, as is clear from the reference in a Latin poem by Claudian, who says magna levi detrudens murmura tactu. Intent, that is “let him thunder forth as he presses out mighty roarings with a light touch”, from its invention until the fourteenth century, the organ remained the only keyboard instrument. Often, the organ did not feature a keyboard at all, almost every keyboard until the fifteenth century had seven naturals to each octave. The clavichord and the harpsichord appeared during the 14th century—the clavichord probably being earlier, the harpsichord and clavichord were both common until widespread adoption of the piano in the 18th century, after which their popularity decreased. The piano was revolutionary, because a pianist could vary the volume of the sound by varying the vigor with which each key was struck. The pianos full name is gravicèmbalo con piano e forte meaning harpsichord with soft and loud but can be shortened to piano-forte, which means soft-loud in Italian. In its current form, the piano is a product of the late 19th century, in fact, the modern piano is significantly different from even the 19th-century pianos used by Liszt, Chopin, and Brahms. See Piano history and musical performance, keyboard instruments were further developed in the early twentieth century. Early electromechanical instruments, such as the Ondes Martenot, appeared early in the century and this was a very important contribution to the keyboards history. Much effort has gone into creating an instrument that sounds like the piano but lacks its size, the electric piano and electronic piano were early efforts that, while useful instruments in their own right, did not convincingly reproduce the timbre of the piano. Electric and electronic organs were developed during the same period, more recent electronic keyboard designs strive to emulate the sound of specific make and model pianos using digital samples and computer models. Concerns celebrated keyboard players and the various instruments used over the centuries

Piano
–
The piano is an acoustic, stringed musical instrument invented around the year 1700, in which the strings are struck by hammers. It is played using a keyboard, which is a row of keys that the performer presses down or strikes with the fingers and thumbs of both hands to cause the hammers to strike the strings. The word piano is a form of pianoforte, the Italian term for the early 1700s versions of the instrument. The first fortepianos in the 1700s had a sound and smaller dynamic range. An acoustic piano usually has a wooden case surrounding the soundboard and metal strings. Pressing one or more keys on the keyboard causes a padded hammer to strike the strings. The hammer rebounds from the strings, and the continue to vibrate at their resonant frequency. These vibrations are transmitted through a bridge to a soundboard that amplifies by more efficiently coupling the acoustic energy to the air, when the key is released, a damper stops the strings vibration, ending the sound. Notes can be sustained, even when the keys are released by the fingers and thumbs and this means that the piano can play 88 different pitches, going from the deepest bass range to the highest treble. The black keys are for the accidentals, which are needed to play in all twelve keys, more rarely, some pianos have additional keys. Most notes have three strings, except for the bass that graduates from one to two, the strings are sounded when keys are pressed or struck, and silenced by dampers when the hands are lifted from the keyboard. There are two types of piano, the grand piano and the upright piano. The grand piano is used for Classical solos, chamber music and art song and it is used in jazz. The upright piano, which is compact, is the most popular type, as they are a better size for use in private homes for domestic music-making. During the nineteenth century, music publishers produced many works in arrangements for piano, so that music lovers could play. The piano is widely employed in classical, jazz, traditional and popular music for solo and ensemble performances, accompaniment, with technological advances, amplified electric pianos, electronic pianos, and digital pianos have also been developed. The electric piano became an instrument in the 1960s and 1970s genres of jazz fusion, funk music. The piano was founded on earlier technological innovations in keyboard instruments, pipe organs have been used since Antiquity, and as such, the development of pipe organs enabled instrument builders to learn about creating keyboard mechanisms for sounding pitches

Harpsichord
–
A harpsichord is a musical instrument played by means of a keyboard. It produces sound by plucking a string when a key is pressed, Harpsichord designates the whole family of similar plucked keyboard instruments, including the smaller virginals, muselar, and spinet. The harpsichord was used in Renaissance and Baroque music. During the late 18th century, it disappeared from the musical scene with the rise of the piano. In the 20th century, it made a resurgence, being used in historically informed performances of music, in compositions. Harpsichords vary in size and shape, but all have the basic functional arrangement. The player depresses a key that rocks over a pivot in the middle of its length, the other end of the key lifts a jack that holds a small plectrum, which plucks the string. When the player releases the key, the far end returns to its rest position, the plectrum, mounted on a tongue that can swivel backwards away from the string, passes the string without plucking it again. As the key reaches its rest position, a felt damper atop the jack stops the strings vibrations and these basic principles are explained in detail below. The keylever is a pivot, which rocks on a balance pin that passes through a hole drilled through the keylever. The jack is a thin, rectangular piece of wood that sits upright on the end of the keylever, the jacks are held in place by the registers. These are two strips of wood, which run in the gap between pinblock and bellyrail. The registers have rectangular mortises through which the pass as they can move up. The registers hold the jacks in the location needed to pluck the string. In the jack, a plectrum juts out almost horizontally and passes just under the string, historically, plectra were made of bird quill or leather, many modern harpsichords have plastic plectra. When the front of the key is pressed, the back of the key rises, the jack is lifted, the vertical motion of the jack is then stopped by the jackrail, which is covered with soft felt to muffle the impact. When the key is released, the falls back down under its own weight. This is made possible by having the plectrum held in a tongue attached with a pivot and a spring to the body of the jack

Celesta
–
The celesta /sᵻˈlɛstə/ or celeste /sᵻˈlɛst/ is a struck idiophone operated by a keyboard. It looks similar to a piano, albeit with smaller keys. The keys connect to hammers that strike a set of metal plates or bars suspended over wooden resonators. Four- or five-octave models usually have a pedal that sustains or damps the sound. The three-octave instruments do not have a pedal because of their small table-top design, one of the best-known works that uses the celesta is Tchaikovskys Dance of the Sugar Plum Fairy from The Nutcracker. The sound of the celesta is similar to that of the glockenspiel and this quality gave the instrument its name, celeste meaning heavenly in French. The celesta is used to enhance a melody line played by another instrument or section. The delicate, bell-like sound is not loud enough to be used in full ensemble sections, as well, the celesta is a transposing instrument, it sounds one octave higher than the written pitch. Its sounding range is considered to be C4 to C8. The original French instrument had a range, but because the lowest octave was considered somewhat unsatisfactory. The standard French four-octave instrument is now gradually being replaced in symphony orchestras by a larger, although it is a member of the percussion family, in orchestral terms it is more properly considered a member of the keyboard section and usually played by a keyboardist. The celesta part is written on two braced staves, called a grand staff. The celesta was invented in 1886 by Parisian harmonium builder Auguste Mustel and his father, Victor Mustel, had developed the forerunner of the celesta, the typophone, in 1860. This instrument produced sound by striking tuning forks instead of the plates that would be used in the celesta. The dulcitone functioned identically to the typophone and was developed concurrently in Scotland, the typophone/dulcitones uses were limited by its low volume, too quiet to be heard in a full orchestra. Pyotr Tchaikovsky is usually cited as the first major composer to use this instrument in a work for symphony orchestra. He first used it in his symphonic poem The Voyevoda, Op. posth. The following year, he used the celesta in passages in his ballet The Nutcracker, most notably in the Dance of the Sugar Plum Fairy, which also appears in the derived Nutcracker Suite, Op. 71a

Boethius
–
Anicius Manlius Severinus Boëthius, commonly called Boethius, was a Roman senator, consul, magister officiorum, and philosopher of the early 6th century. Boethius was born in Rome to a family around 480 AD. His family, the Anicii, included emperors Petronius Maximus and Olybrius and his father, Manlius Boethius, who was appointed consul in 487, died while Boethius was young. Another patrician, Quintus Aurelius Memmius Symmachus, adopted and raised Boethius, instilling in him a love for literature and philosophy. Both Memmius Symmachus and Boethius were fluent in Greek, a rare skill at the time in the Western Empire, for this reason. The French scholar Pierre Courcelle has argued that Boethius studied at Alexandria with the Neo-Platonist philosopher Ammonius Hermiae, on account of his erudition, Boethius entered the service of Theodoric the Great at a young age and was already a senator by the age of 25. Boethius married his foster-fathers daughter, Rusticiana, their children included two boys, Symmachus and Boethius. In 522, the year his two sons were appointed joint consuls, Boethius accepted the appointment to the position of magister officiorum. This may have set in place a course of events that would lead to loss of royal favour, five hundred years later, this continuing disagreement led to the East-West Schism in 1054, in which communion between the Catholic Church and Eastern Orthodox Church was broken. In 523 Boethius fell from power, after a period of imprisonment in Pavia for what was deemed a treasonable offence, he was executed in 524. The primary sources are in agreement over the facts of what happened. At a meeting of the Royal Council in Verona, the referandarius Cyprianus accused the ex-consul Caecina Decius Faustus Albinus of treasonous correspondence with Justin I. Boethius leapt to his defense, crying, The charge of Cyprianus is false, but if Albinus did that, so also have I, Cyprianus then also accused Boethius of the same crime, and produced three men who claimed they had witnessed the crime. First the pair were detained in the baptistery of a church, then Boethius was exiled to the Ager Calventianus, a distant country estate, the basic facts in the case are not in dispute, writes Jeffrey Richards. What is disputed about this sequence of events is the interpretation that should be put on them, Boethius claims his crime was seeking the safety of the Senate. He describes the three witnesses against him as dishonorable, Basilius had been dismissed from Royal service for his debts, while Venantius Opilio, however, other sources depict these men in a far more positive light. For example, Cassiodorus describes Cyprianus and Opilio as utterly scrupulous, just and loyal and mentions they are brothers, Theodoric was feeling threatened by international events. The Acacian Schism had been resolved, and the Nicene Christian aristocrats of his kingdom were seeking to renew their ties with Constantinople, the Catholic Hilderic had become king of the Vandals and had put Theodorics sister Amalafrida to death, and Arians in the East were being persecuted

Cassiodorus
–
Flavius Magnus Aurelius Cassiodorus Senator, commonly known as Cassiodorus, was a Roman statesman and writer serving in the administration of Theoderic the Great, king of the Ostrogoths. Senator was part of his surname, not his rank, Cassiodorus was born at Scylletium, near Catanzaro in Calabria, Italy. He began his career as councillor to his father, the governor of Sicily, while still young, he made a name for himself as learned in the ways of law. During his working life he worked as quaestor sacri palatii c, 507–511, as a consul in 514, then as magister officiorum under Theoderic, and later under the regency for Theoderics young successor, Athalaric. Cassiodorus kept copious records and letterbooks concerning public affairs, at the Gothic court his literary skill, which seems mannered and rhetorical to modern readers, was so esteemed that when in Ravenna he was often entrusted with drafting significant public documents. His culminating appointment was as praetorian prefect for Italy, effectively the prime ministership of the Ostrogothic civil government, Cassiodorus also collaborated with Pope Agapetus I in establishing a library of Greek and Latin texts which were intended to support a Christian school in Rome. In addition, Boethius father-in-law Symmachus, by this time a distinguished elder statesman, all this was a result of the worsening split between the ancient senatorial aristocracy centered in Rome and the adherents of Gothic rule at Ravenna. But to read Cassiodorus Variae one would never suspect such goings-on, there is no mention in Cassiodorus selection of official correspondence of the death of Boethius. Athalaric died in early 534, and the remainder of Cassiodorus public career was dominated by the Byzantine reconquest and his last letters were drafted in the name of Vitiges. Around 537-38, he left Italy for Constantinople, where his successor was appointed from and he notably met Junillus, the quaestor of Justinian. His Constantinopolitan journey contributed to the improvement of his religious knowledge, Cassiodorus spent his career trying to bridge the 6th century cultural divides, between East and West, Greek culture and Latin, Roman and Goth, and between an Orthodox people and their Arian ruler. He speaks fondly in his Institutiones of Dionysius Exiguus, the calculator of the Anno Domini era, in his retirement he founded the monastery of Vivarium on his family estates on the shores of the Ionian Sea, and his writings turned to religion. Cassiodorus Vivarium monastery school was composed of two buildings, a coenobitic monastery and a retreat, for those who desired a more solitary life. Both were located on the site of the modern Santa Maria de Vetere near Squillace, the twin structure of Vivarium was to permit coenobitic monks and hermits to coexist. The Vivarium appears not to have governed by a strict monastic rule. Rather Cassiodorus Institutiones was written to guide the monks studies, to this end, the Institutiones focuses largely on texts assumed to have been available in Vivariums library. The Institutiones seem to have composed over a lengthy period of time, from the 530s into the 550s. Through them I believe that both the sequence of Holy Scripture and also a compact account of secular letters may, with Gods grace

Roger Bacon
–
In the early modern era, he was regarded as a wizard and particularly famed for the story of his mechanical or necromantic brazen head. He is sometimes credited as one of the earliest European advocates of the scientific method inspired by Aristotle. His linguistic work has been heralded for its exposition of a universal grammar. However, more recent re-evaluations emphasise that Bacon was essentially a medieval thinker and he was, however, partially responsible for a revision of the medieval university curriculum, which saw the addition of optics to the traditional quadrivium. A survey of how Bacons work was received over the found that it often reflected the concerns. Bacons major work, the Opus Majus, was sent to Pope Clement IV in Rome in 1267 upon the popes request, although gunpowder was first invented and described in China, Bacon was the first in Europe to record its formula. Roger Bacon was born in Ilchester in Somerset, England, in the early 13th century, although his date of birth is sometimes narrowed down to c. 1210,1213 or 1214, however, historians most agree on c. 1220. The only source for his date is a statement from his 1267 Opus Tertium that forty years have passed since I first learned the Alphabetum. His family appears to have been well off, Bacon became a master at Oxford, lecturing on Aristotle. There is no evidence he was awarded a doctorate. A caustic cleric named Roger Bacon is recorded speaking before the king at Oxford in 1233, in 1237 or some time over the next decade, he accepted an invitation to teach at the University of Paris. While there, he lectured on Latin grammar, Aristotelian logic, arithmetic, geometry, and his faculty colleagues included Robert Kilwardby, Albertus Magnus, and Peter of Spain, the future Pope John XXI. The Cornishman Richard Rufus was a scholarly opponent, in 1247 or soon after, he left his position in Paris. As a private scholar, his whereabouts for the decade are uncertain but he was likely in Oxford c. 1248–51, where he met Adam Marsh. He seems to have studied most of the known Greek and Arabic works on optics, a passage in the Opus Tertium states that at some point he took a two-year break from his studies. Pope Urban IV absolved the king of his oath in 1261 and, after an initial abortive resistance, Bacons own family were considered royal partisans, De Montforts men seized their property and drove several members into exile. In 1256 or 57, he became a friar in the Franciscan Order in either Paris or Oxford, following the example of scholarly English Franciscans such as Grosseteste and Marsh. After 1260, Bacons activities were restricted by a statute prohibiting the friars of his order from publishing books or pamphlets without prior approval

Filippo Bonanni
–
Filippo Bonanni, S. J. or Buonanni was an Italian Jesuit scholar. His many works included treatises on fields ranging from anatomy to music and he created the earliest practical illustrated guide for shell collectors in 1681, for which he is considered a founder of conchology. He also published a study of lacquer that has been of lasting value since his death, Bonanni was born in Rome in 1638, and entered the Society of Jesus in 1654, when he was still 17 years old. After his novitiate, in 1656 he was sent to study at the Societys noted Roman College, there he became a pupil of the German scientist, Athanasius Kircher. While a student there, he undertook the manufacturing of microscopic lenses and he used his lenses to create his own microscope and to develop scientific studies of a number of specimens. He also became a copper plate engraver. From Rome, Bonanni was sent to teach in the Jesuit Colleges of Orvieto, upon Kirchers resignation of the post of Professor of Mathematics at the Roman College, Bonanni was chosen to succeed him. After Kirchers death in 1698, Bonanni was appointed curator of the cabinet of curiosities gathered by Kircher. He published a catalogue of the collection in 1709, titled Musæum Kicherianum, Bonanni followed Aristotle in believing in theories of spontaneous generation. In critiquing the work of Francesco Redi, Bonanni defended the Aristotelian view. Nonetheless, in writing about the nature and origins of fossils, Bonanni admitted doubts about whether theories of transport could account for the numbers. He later speculated that fossils could be divided into two groups—the remains of organisms, and the products of natural powers, such interpretations were consistent with the new and challenging idea that the earth must have undergone extraordinary alterations to explain the diversity of types and locations of fossils. Bonanni created the earliest practical illustrated guide for collectors, Recreatione dellocchio e della mente. The two-volume guide was the first treatise devoted entirely to molluscs, Bonannis work is significant for his careful attempts to precisely describe shell morphology. Unfortunately, due to the printing and engraving process, the spirals shown on the shells were reversed from dextral to sinistral, a mirror image problem that later books avoided. Zoological taxonomies of the time were based on visual characteristics, although his work predated the adoption of Linnaeus system of binomial nomenclature, Bonanni laid the foundation for the new discipline of conchology. Several later Linnaean names were based on Bonannis work, including the name of the class Bivalvia, among other topics, Bonanni wrote of the ingredients craftsmen in China used to make the lacquer they used on porcelain, a popular import item for Europe at the time. Like other researchers of the day, he went on to experiment with recipes to recreate the lacquer used on porcelain

Near East
–
The Near East is a geographical term that roughly encompasses Western Asia. Despite having varying definitions within different academic circles, the term was applied to the maximum extent of the Ottoman Empire. The term has fallen into disuse in English and has replaced by the terms Middle East. The Food and Agriculture Organization of the United Nations defines the region similarly, but also includes Afghanistan while excluding the countries of North Africa and the Palestinian territories. Up until 1912 the Ottomans retained a band of territory including Albania, Macedonia and Southern Thrace, the Ottoman Empire, believed to be about to collapse, was portrayed in the press as the sick man of Europe. The Balkan states, with the exception of Bosnia and Albania, were primarily Christian. Starting in 1894 the Ottomans struck at the Armenians on the grounds that they were a non-Muslim people. The Hamidian Massacres aroused the indignation of the entire Christian world, in the United States the now aging Julia Ward Howe, author of the Battle Hymn of the Republic, leaped into the war of words and joined the Red Cross. Relations of minorities within the Ottoman Empire and the disposition of former Ottoman lands became known as the Eastern Question and it now became relevant to define the east of the eastern question. In about the middle of the 19th century Near East came into use to describe part of the east closest to Europe. The term Far East appeared contemporaneously meaning Japan, China, Korea, Indonesia, near East applied to what had been mainly known as the Levant, which was in the jurisdiction of the Ottoman Porte, or government. Those who used the term had little choice about its meaning and they could not set foot on most of the shores of the southern and central Mediterranean from the Gulf of Sidra to Albania without permits from the Ottoman Empire. Some regions beyond the Ottoman Porte were included, one was North Africa west of Egypt. It was occupied by piratical kingdoms of the Barbary Coast, de facto independent since the 18th century, formerly part of the empire at its apogee. Iran was included because it could not easily be reached except through the Ottoman Empire or neighboring Russia, in the 1890s the term tended to focus on the conflicts in the Balkan states and Armenia. The demise of the man of Europe left considerable confusion as to what was to be meant by Near East. It is now used only in historical contexts, to describe the countries of Western Asia from the Mediterranean to Iran. There is, in short, no universally understood fixed inventory of nations and they appear together in the journals of the mid-19th century

Hellenistic Greece
–
During the Hellenistic period the importance of Greece proper within the Greek-speaking world declined sharply. The great centers of Hellenistic culture were Alexandria and Antioch, capitals of Ptolemaic Egypt, cities such as Pergamon, Ephesus, Rhodes and Seleucia were also important, and increasing urbanization of the Eastern Mediterranean was characteristic of the time. The quests of Alexander had a number of consequences for the Greek city-states and it greatly widened the horizons of the Greeks, making the endless conflicts between the cities which had marked the 5th and 4th centuries BC seem petty and unimportant. It led to a steady emigration, particularly of the young and ambitious, the Greeks valued their local independence too much to consider actual unification, but they made several attempts to form federations through which they could hope to reassert their independence. Following Alexanders death a struggle for power broke out among his generals, which resulted in the break-up of his empire, Macedon fell to Cassander, son of Alexanders leading general Antipater, who after several years of warfare made himself master of most of the rest of Greece. He founded a new Macedonian capital at Thessaloniki and was generally a constructive ruler, Cassanders power was challenged by Antigonus, ruler of Anatolia, who promised the Greek cities that he would restore their freedom if they supported him. This led to successful revolts against Cassanders local rulers, in 307 BC, Antigonuss son Demetrius captured Athens and restored its democratic system, which had been suppressed by Alexander. But in 301 BC a coalition of Cassander and the other Hellenistic kings defeated Antigonus at the Battle of Ipsus, after Cassanders death in 298 BC, however, Demetrius seized the Macedonian throne and gained control of most of Greece. He was defeated by a coalition of Greek rulers in 285 BC. Lysimachus was in turn defeated and killed in 280 BC, the Macedonian throne then passed to Demetriuss son Antigonus II, who also defeated an invasion of the Greek lands by the Gauls, who at this time were living in the Balkans. The battle against the Gauls united the Antigonids of Macedon and the Seleucids of Antioch, an alliance which was directed against the wealthiest Hellenistic power. Antigonus II ruled until his death in 239 BC, and his family retained the Macedonian throne until it was abolished by the Romans in 146 BC. Their control over the Greek city states was intermittent, however, since other rulers, particularly the Ptolemies, Sparta also remained independent, but generally refused to join any league. In 267 BC, Ptolemy II persuaded the Greek cities to revolt against Antigonus, in became the Chremonidian War. The cities were defeated and Athens lost her independence and her democratic institutions, the Aetolian League was restricted to the Peloponnese, but on being allowed to gain control of Thebes in 245 BC became a Macedonian ally. This marked the end of Athens as a actor, although it remained the largest, wealthiest and most cultivated city in Greece. In 255 BC, Antigonus defeated the Egyptian fleet at Cos and brought the Aegean islands, except Rhodes, in spite of their decreased political power and autonomy, the Greek city state or polis continued to be the basic form of political and social organization in Greece. Classical city states such as Athens and Ephesus grew and even thrived in this period, the Aetolians and the Achaeans developed strong federal states or leagues, which were governed by councils of city representatives and assemblies of league citizens

Tboli people
–
The Tboli are one of the indigenous peoples of South Cotabato in Southern Mindanao. From the body of ethnographic and linguistic literature on Mindanao they are known as Tboli, Tboli, Tböli, Tiboli, Tibole, Tagabili, Tagabeli. They term themselves Tboli or Tboli, the Tbolis, then, reside on the mountain slopes on either side of the upper Alah Valley and the coastal area of Maitum, Maasim and Kiamba. In former times, the Tbolis also inhabited the upper Alah Valley floor, after World War Two, i. e. since the arrival of settlers originating from other parts of the Philippines, they have been gradually pushed onto the mountain slopes. As of now, they are almost expelled from the valley floor. As opposed to the indigenous Muslim peoples or the Christian settlers, in political contexts, however, the term Lumad groups has become popular as a generic term for the various indigenous peoples of Mindanao

Mindanao
–
Mindanao is the second largest and southernmost major island in the Philippines.
