[EX Q]: Context: A stepper is a device used in the manufacture of integrated circuits (ICs) that is similar in operation to a slide projector or a photographic enlarger. Steppers are an essential part of the complex process, called photolithography, that creates millions of microscopic circuit elements on the surface of tiny chips of silicon. These chips form the heart of ICs such as computer processors, memory chips, and many other devices., Pentax () is a brand name used primarily by Ricoh Imaging Company for cameras, sport optics (including binoculars and rifle scopes), and CCTV optics. The brand is also used by Hoya Corporation for medical products & services, TI Asahi for surveying instruments, and Seiko Optical Products for certain optical lenses., A camera lens (also known as photographic lens or photographic objective) is an optical lens or assembly of lenses used in conjunction with a camera body and mechanism to make images of objects either on photographic film or on other media capable of storing an image chemically or electronically., The Nikon F camera, introduced in April 1959, was Nikon's first SLR camera. It was one of the most advanced cameras of its day. Although many of the concepts had already been introduced elsewhere, it was revolutionary in that it was the first to combine them all in one camera. It was produced until October 1973 and was replaced by the quite similar Nikon F2. Aspects of its design remain in all of Nikon's subsequent SLR cameras, through the current Nikon F6 film and Nikon D5 digital models (which still share its Nikon F-mount for lenses). The "F" in Nikon F was selected by Nippon Kogaku from the letter F of the name of the designer of the bayonet mount, Mr. Fuketa. That tradition was carried all the way through their top line of Nikon cameras until the introduction of the Nikon D1 (digital) cameras decades later., Large format refers to any imaging format of 4×5 inches (102×127 mm) or larger. Large format is larger than "medium format", the 6×6 cm (2×2 inch) or 6×9 cm (2×3 inch) size of Hasselblad, Rollei, Kowa, and Pentax cameras (using 120- and 220-roll film), and much larger than the 24×36 mm (~ 1.0x1.5 inch) frame of 35 mm format.
The main advantage of large format, film or digital, is higher resolution at the same pixel pitch, or same resolution with more larger pixels or grain. A 4×5 inch image has about 16 times the area, and thus 16× the total resolution, of a 35 mm frame., 35 mm film (millimeter) is the film gauge most commonly used for motion pictures and chemical still photography (see 135 film). The name of the gauge refers to the width of the photographic film, which consists of strips 34.98 ±0.03 mm (1.377 ±0.001 inches) wide. The standard negative pulldown for movies ("single-frame" format) is four perforations per frame along both edges, which results in 16 frames per foot of film. For still photography, the standard frame has eight perforations on each side., A microscope (from the , "mikrós", "small" and , "skopeîn", "to look" or "see") is an instrument used to see objects that are too small for the naked eye. The science of investigating small objects using such an instrument is called microscopy. Microscopic means invisible to the eye unless aided by a microscope., , formerly known as , is a Japanese multinational electronics corporation headquartered in Kadoma, Osaka, Japan., Nikonos Calypso is the name of a series of 35mm format cameras specifically designed for underwater photography launched by Nikon in 1963. The early Nikonos cameras were improvements of the Calypso camera, which was an original design by Jacques-Yves Cousteau and Belgian engineer Jean de Wouters, Binoculars or field glasses are binocular telescopes mounted side-by-side and aligned to point in the same direction, allowing the viewer to use both eyes (binocular vision) when viewing distant objects. Most are sized to be held using both hands, although sizes vary widely from opera glasses to large pedestal mounted military models., Sony Corporation is the electronics business unit and the parent company of the Sony Group, which is engaged in business through its four operating components  electronics (video games, network services and medical business), motion pictures, music and financial services. These make Sony one of the most comprehensive entertainment companies in the world. Sony's principal business operations include Sony Corporation, Sony Pictures Entertainment, Sony Interactive Entertainment, Sony Music Entertainment, Sony Mobile (formerly Sony Ericsson) and Sony Financial. Sony is among the Semiconductor sales leaders by year and as of 2013, the fourth-largest television manufacturer in the world, after Samsung Electronics, LG Electronics and TCL., Its products include cameras, camera lenses, binoculars, microscopes, ophthalmic lenses, measurement instruments, rifle scopes, spotting scopes, and the steppers used in the photolithography steps of semiconductor fabrication, of which it is the world's second largest manufacturer. The companies held by Nikon form the Nikon Group. Among its products are Nikkor imaging lenses (for F-mount cameras, large format photography, photographic enlargers, and other applications), the Nikon F-series of 35 mm film SLR cameras, the Nikon D-series of digital SLR cameras, the Coolpix series of compact digital cameras, and the Nikonos series of underwater film cameras. Nikon's main competitors in camera and lens manufacturing include Canon, Sony, Fujifilm, Panasonic, Pentax, and Olympus., , better known as Fujifilm or simply Fuji, stylized as FUJiFILM, is a Japanese multinational photography and imaging company headquartered in Tokyo., Photolithography, also termed optical lithography or UV lithography, is a process used in microfabrication to pattern parts of a thin film or the bulk of a substrate. It uses light to transfer a geometric pattern from a photomask to a light-sensitive chemical "photoresist", or simply "resist," on the substrate. A series of chemical treatments then either engraves the exposure pattern into, or enables deposition of a new material in the desired pattern upon, the material underneath the photo resist. For example, in complex integrated circuits, a modern CMOS wafer will go through the photolithographic cycle up to 50 times., Nikkor is the brand of lenses produced by Nikon Corporation, including camera lenses for the Nikon F-mount., The 70 - 300mm lens is a telephoto zoom lens made by Nikon . The lens has an F - mount to work with all the SLRs line of cameras ( except the early 70 - 300G with the D40 ) . The lens comes in four different versions : AF f / 4 - 5.6G AF f / 4 - 5.6D AF f / 4 - 5.6D ED AF - S f / 4.5 - 5.6G IF - ED It is the successor of the 70 - 210 lens , which targets the prosumer market , one grade lower than 80 - 200mm with large aperture . Introduced in August 2006 , the current incarnation of the lens ( AF - S VR f / 4.5 - 5.6G IF - ED ) improves on the original with VR stabilization technology as well as with internally focusing components ( IF ) . More expensive than its partner 55 - 200mm lens , its construction is similar , with the exterior shell being fabricated from plastic components . It also shares a similarly stiff zoom ring with the 55 - 200mm , although a side benefit of this is that zoom creep is eliminated . Unlike the 55 - 200 , the 70 - 300mm lens is full - frame . Also , the longer barrel length allowed the focus ring to be relocated in front of the zoom ring , making manual focus operations simpler ., Measurement is the assignment of a number to a characteristic of an object or event, which can be compared with other objects or events. The scope and application of a measurement is dependent on the context and discipline. In the natural sciences and engineering, measurements do not apply to nominal properties of objects or events, which is consistent with the guidelines of the "International vocabulary of metrology" published by the International Bureau of Weights and Measures. However, in other fields such as statistics as well as the social and behavioral sciences, measurements can have multiple levels, which would include nominal, ordinal, interval, and ratio scales., Subject: nikon f 70-300mm lens, Relation: instance_of, Options: (A) application (B) april (C) area (D) brand (E) camera (F) camera lens (G) canon (H) chemical (I) company (J) complex (K) computer (L) corporation (M) day (N) device (O) eight (P) electronics (Q) event (R) field (S) film (T) format (U) four (V) instrument (W) letter (X) line (Y) lithography (Z) manufacturer ([) manufacturing (\) material (]) measurement (^) microscope (_) motion (`) name (a) negative (b) network (c) object (d) october (e) operation (f) parent company (g) part (h) pattern (i) photography (j) point (k) process (l) revolutionary (m) rifle (n) series (o) side (p) single (q) size (r) statistics

[EX Q]: Context: The Normans (Norman: "Nourmands"; ) were the people who, in the 10th and 11th centuries, gave their name to Normandy, a region in France. They were descended from Norse ("Norman" comes from "Norseman") raiders and pirates from Denmark, Iceland and Norway who, under their leader Rollo, agreed to swear fealty to King Charles III of West Francia. Through generations of assimilation and mixing with the native Frankish and Gallo-Roman populations, their descendants would gradually adopt the Carolingian-based cultures of West Francia, ultimately resulting in their own assimilation into the Romance society. The distinct cultural and ethnic identity of the Normans emerged initially in the first half of the 10th century, and it continued to evolve over the succeeding centuries., The Church of England (C of E) is the Anglican Christian state church of England. Headed by the Archbishop of Canterbury (currently Justin Welby) and primarily governed from London with the monarch as the supreme governor, the Church of England is also the mother church of the international Anglican Communion. The church dates its formal establishment as a national church to the 6th-century Gregorian mission in Kent led by Augustine of Canterbury, with considerable features introduced and established during and following the English Reformation in the 16th century., The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom (UK) or Britain, is a sovereign country in western Europe. Lying off the north-western coast of the European mainland, it includes the island of Great Britain (the name of which is also loosely applied to the whole country), the north-eastern part of the island of Ireland, and many smaller islands. Northern Ireland is the only part of the UK that shares a land border with another sovereign statethe Republic of Ireland. Apart from this land border, the UK is surrounded by the Atlantic Ocean, with the North Sea to its east, the English Channel to its south and the Celtic Sea to its south-south-west, giving it the 12th-longest coastline in the world. The Irish Sea lies between Great Britain and Ireland. With an area of , the UK is the 78th-largest sovereign state in the world and the 11th-largest in Europe. It is also the 21st-most populous country, with an estimated 65.1 million inhabitants. Together, this makes it the fourth most densely populated country in the European Union., Cambridge is a university city and the county town of Cambridgeshire, England, on the River Cam about north of London. At the United Kingdom Census 2011, its population was 123,867, including 24,488 students., Ridley Hall is a theological college located in Sidgwick Avenue in Cambridge in the United Kingdom, which trains men and women intending to take Holy Orders, as deacon or priest of the Church of England and the ministry of other churches. It was founded in 1881 and named in memory of Nicholas Ridley, a leading Protestant theologian of the sixteenth century. The first principal was theologian Handley Moule, later Bishop of Durham., A census of the population of the United Kingdom is taken every ten years. The 2011 census was held in all countries of the UK on 27 March 2011. It was the first UK census which could be completed online via the Internet. The Office for National Statistics (ONS) is responsible for the census in England and Wales, the General Register Office for Scotland (GROS) is responsible for the census in Scotland, and the Northern Ireland Statistics and Research Agency (NISRA) is responsible for the census in Northern Ireland., In the Christian churches, Holy Orders are ordained ministries such as bishop, priest or deacon. In the Roman Catholic (Latin: "sacri ordines"), Eastern Catholic, Eastern Orthodox ( ["hiersyn"],  ["hierateuma"],  ["Svyashchenstvo"]), Oriental Orthodox, Anglican, Assyrian, Old Catholic, Independent Catholic and some Lutheran churches, holy orders is comprised is the three ministerial orders of bishop, priest and deacon, or the sacrament or rite by which candidates are ordained to those orders. Except for Lutherans and some Anglicans, these churches regard ordination as a sacrament (the "sacramentum ordinis"). The Anglo-Catholic tradition within Anglicanism identifies more with the Roman Catholic position about the sacramental nature of ordination., Handley Carr Glyn Moule (23 December 1841  8 May 1920) was an evangelical Anglican theologian, writer, poet, and Bishop of Durham from 1901-1920. , England is a country that is part of the United Kingdom. It shares land borders with Scotland to the north and Wales to the west. The Irish Sea lies northwest of England and the Celtic Sea lies to the southwest. England is separated from continental Europe by the North Sea to the east and the English Channel to the south. The country covers five-eighths of the island of Great Britain (which lies in the North Atlantic) in its centre and south; and includes over 100 smaller islands such as the Isles of Scilly, and the Isle of Wight., The Bishop of Durham is the Anglican bishop responsible for the Diocese of Durham in the Province of York. The diocese is one of the oldest in England and its bishop is a member of the House of Lords. Paul Butler has been the Bishop of Durham since his election was confirmed at York Minster on 20 January 2014. The previous bishop was Justin Welby, Archbishop of Canterbury. The bishop is one of two (the other is the Bishop of Bath and Wells) who escort the sovereign at the coronation., The Bishop of Thetford is an episcopal title which takes its name after the market town of Thetford in Norfolk, England. The title was originally used by the Normans in the 11th century, and is now used by a Church of England suffragan bishop., Hugo Ferdinand de Waal ( 16 March 1935 -- 6 January 2007 ) was Principal of Ridley Hall , Cambridge from 1978 to 1991 and the suffragan Bishop of Thetford from 1992 until 2000 . He was born at Jember on East Java and educated at Tonbridge School and Pembroke College , Cambridge before embarking on an ecclesiastical career with a curacy at St Martin in the Bull Ring after which he was Chaplain at his old college then Rector of Dry Drayton . Following this he was Vicar of St John the Evangelist , Blackpool and then ( his final appointment before elevation to the Episcopate ) Principal of Ridley Hall theological college in Cambridge ( 1978 -- 91 ) . In retirement he continued to serve the Church as an honorary assistant bishop within the Diocese in Europe until his death ., The River Cam is the main river flowing through Cambridge in eastern England. After leaving Cambridge, it flows north and east into the Great Ouse to the south of Ely at Pope's Corner. The Great Ouse connects the Cam to the North Sea at King's Lynn: The total distance from Cambridge to the sea is about and is navigable for punts, small boats, and rowing craft. The Great Ouse also connects to England's canal system via the Middle Level Navigations and the River Nene. In total, the Cam runs for around from its furthest source (near Debden in Essex) to its confluence with the Great Ouse. , Subject: hugo de waal, Relation: occupation, Options: (A) archbishop (B) bishop (C) butler (D) deacon (E) general (F) king (G) leader (H) member (I) monarch (J) poet (K) priest (L) research (M) theologian (N) united kingdom

[EX Q]: Context: The piano is an acoustic, stringed musical instrument, in which the strings are struck by hammers. It is played using a keyboard, which is a row of keys (small levers) that the performer presses down or strikes with the fingers and thumbs of both hands to cause the hammers to strike the strings. Invented in about 1700 (the exact year is uncertain), the piano is widely employed in classical, jazz, traditional and popular music for solo and ensemble performances, accompaniment, and for composing, songwriting and rehearsals. Although the piano is very heavy and thus not portable and is expensive (in comparison with other widely used accompaniment instruments, such as the acoustic guitar), its musical versatility (i.e., its wide pitch range, ability to play chords with up to 10 notes, louder or softer notes and two or more independent musical lines at the same time), the large number of musicians and amateurs trained in playing it, and its wide availability in performance venues, schools and rehearsal spaces have made it one of the Western world's most familiar musical instruments., A concerto (from the , plural "concerti" or, often, the anglicised form "concertos") is a musical composition, whose characteristics have changed over time. In the 17th century, "sacred works for voices and orchestra were typically called concertos." J. S. Bach "was thus reflecting a long-standing tradition when he used the title 'concerto' for many of the works that we know as cantatas.". But in recent centuries, up to the present, a concerto is a piece usually composed in three parts or movements, in which (usually) one solo instrument (for instance, a piano, violin, cello or flute) is accompanied by an orchestra or concert band., Wolfgang Amadeus Mozart was a prolific composer and wrote in many genres . Perhaps his best - admired work is in opera , the piano concerto and sonata , the symphony , and in the string quartet and string quintet . Mozart also wrote much work for solo piano , other forms of chamber music , masses and other religious music , and numerous dances , divertimentos , and other forms of light entertainment ., A musical ensemble, also known as a music group or musical group, is a group of people who perform instrumental and/or vocal music, with the ensemble typically known by a distinct name. Some music ensembles consist solely of instruments, such as the jazz quartet or the orchestra. Some music ensembles consist solely of singers, such as choirs and doo wop groups. In both popular music and classical music, there are ensembles in which both instrumentalists and singers perform, such as the rock band or the Baroque chamber group for basso continuo (harpsichord and cello) and one or more singers. In classical music, trios or quartets either blend the sounds of musical instrument families (such as piano, strings, and wind instruments) or group together instruments from the same instrument family, such as string ensembles (e.g., string quartet) or wind ensembles (e.g., wind quintet). Some ensembles blend the sounds of a variety of instrument families, such as the orchestra, which uses a string section, brass instruments, woodwinds and percussion instruments, or the concert band, which uses brass, woodwinds and percussion. , In music, a serenade (or sometimes serenata, from the Italian word) is a musical composition, and/or performance, in someone's honor. Serenades are typically calm, light music., Dance is a performance art form consisting of purposefully selected sequences of human movement. This movement has aesthetic and symbolic value, and is acknowledged as dance by performers and observers within a particular culture. Dance can be categorized and described by its choreography, by its repertoire of movements, or by its historical period or place of origin., Chamber music is a form of classical music that is composed for a small group of instrumentstraditionally a group that could fit in a palace chamber or a large room. Most broadly, it includes any art music that is performed by a small number of performers, with one performer to a part (in contrast to orchestral music, in which each string part is played by a number of performers). However, by convention, it usually does not include solo instrument performances., A piano concerto is a type of concerto, a solo composition in the Classical music genre which is composed for a piano player, which is typically accompanied by an orchestra or other large ensemble. Piano concertos are typically virtuoso showpieces which require an advanced level of technique on the instrument, including melodic lines interspersed with rapid scales, arpeggios, chords, complex contrapuntal parts and other challenging material. When piano concertos are performed by a professional concert pianist, a large grand piano is almost always used, as the grand piano has a fuller tone and more projection than an upright piano. Piano concertos are typically written out in music notation, including sheet music for the pianist (which they typically memorize so that they can play the concert without sheet music), orchestra parts for the orchestra members, and a full score for the conductor, who leads the orchestra in the accompaniment of the soloist. , Art music (also known as Western classical music, cultivated music, serious music, canonic music, or more flippantly, "real music" and "normal music") is an umbrella term that refers to musical traditions, implying advanced structural and theoretical considerations and a written musical tradition. The main tradition in the Western world is usually called classical music. "Serious" or "cultivated" music are terms frequently used as a contrast for ordinary, everyday music (popular and folk music, also called "vernacular music"). After the 20th century, art music was divided into two extensions: "serious music" and "light music"., Recitative (also known by its Italian name "recitativo") is a style of delivery (much used in operas, oratorios, and cantatas) in which a singer is allowed to adopt the rhythms of ordinary speech. Recitative does not repeat lines as formally composed songs do. It resembles sung ordinary speech more than a formal musical composition., Accompaniment is the musical parts which provide the rhythmic and/or harmonic support for the melody or main themes of a song or instrumental piece. There are many different styles and types of accompaniment in different genres and styles of music. In homophonic music, the main accompaniment approach used in popular music, a clear vocal melody is supported by subordinate chords. In popular music and traditional music, the accompaniment parts typically provide the "beat" for the music and outline the chord progression of the song or instrumental piece. The accompaniment for a vocal melody or instrumental solo can be played by a single musician playing an instrument such as piano, pipe organ, or guitar. While any instrument can in theory be used as an accompaniment instrument, keyboard and guitar-family instruments tend to be used if there is only a single instrument, as these instruments can play chords and basslines simultaneously (chords and a bassline are easier to play simultaneously on keyboard instruments, but a fingerpicking guitarist can play chords and a bassline simultaneously on guitar). A solo singer can accompany herself by playing guitar or piano while she sings, and in some rare cases, a solo singer can even accompany himself or herself just using his or her voice and body (e.g., Bobby McFerrin)., The cello (; plural cellos or celli) or violoncello is a bowed string instrument with four strings tuned in perfect fifths. The strings from low to high are generally tuned to C, G, D and A, an octave lower than the viola. It is a member of the violin family of musical instruments, which also includes the violin and viola., Sonata form (also "sonata-allegro form" or "first movement form") is a musical structure consisting of three main sections: an exposition, a development, and a recapitulation. It has been used widely since the middle of the 18th century (the early Classical period)., The double bass or simply the bass (and numerous other names) is the largest and lowest-pitched bowed string instrument in the modern symphony orchestra. It is a transposing instrument and is typically notated one octave higher than sounding to avoid excessive ledger lines below the staff. The double bass is the only modern bowed string instrument that is tuned in fourths (like a viol), rather than fifths, with strings usually tuned to E, A, D and G. The instrument's exact lineage is still a matter of some debate, with scholars divided on whether the bass is derived from the viol or the violin family., A libretto is the text used in, or intended for, an extended musical work such as an opera, operetta, masque, oratorio, cantata or musical. The term "libretto" is also sometimes used to refer to the text of major liturgical works, such as the Mass, requiem and sacred cantata, or the story line of a ballet., Acting is an activity in which a story is told by means of its enactment by an actor or actress who adopts a characterin theatre, television, film, radio, or any other medium that makes use of the mimetic mode., A string quintet is a musical composition for five string players. As an extension to the string quartet (two violins, a viola, and a cello), a string quintet includes a fifth string instrument, usually a second viola (a so-called "viola quintet") or a second cello (a "cello quintet"), or occasionally a double bass., Classical music is art music produced or rooted in the traditions of Western music, including both liturgical (religious) and secular music. While a more accurate term is also used to refer to the period from 1750 to 1820 (the Classical period), this article is about the broad span of time from roughly the 11th century to the present day, which includes the Classical period and various other periods. The central norms of this tradition became codified between 1550 and 1900, which is known as the common-practice period. The major time divisions of Western art music are as follows: 
European art music is largely distinguished from many other non-European and some popular musical forms by its system of staff notation, in use since about the 16th century. Western staff notation is used by composers to indicate to the performer the pitches (e.g., melodies, basslines, chords), tempo, meter and rhythms for a piece of music. This can leave less room for practices such as improvisation and "ad libitum" ornamentation, which are frequently heard in non-European art music and in popular-music styles such as jazz and blues. Another difference is that whereas most popular styles adopt the song (strophic) form, classical music has been noted for its development of highly sophisticated forms of instrumental music such as the concerto, symphony, sonata, and mixed vocal and instrumental styles such as opera which, since they are written down, can sustain larger forms and attain a high level of complexity., An opera house is a theatre building used for opera performances that consists of a stage, an orchestra pit, audience seating, and backstage facilities for costumes and set building. While some venues are constructed specifically for operas, other opera houses are part of larger performing arts centers., The viola is a bowed and plucked string instrument. It is slightly larger than a violin and has a lower and deeper sound than a violin. Since the 18th century it has been the middle or alto voice of the violin family, between the violin (which is tuned a perfect fifth above it) and the cello (which is tuned an octave below it).The strings from low to high are generally tuned to C, G, D, and A., A string quartet is a musical ensemble of four string players  two violin players, a viola player and a cellist  or a piece written to be performed by such a group. The string quartet is one of the most prominent chamber ensembles in classical music, with most major composers, from the mid to late 18th century onwards, writing string quartets., Opera (English plural: "operas"; Italian plural: "opere" ) is an art form in which singers and musicians perform a dramatic work combining text (libretto) and musical score, usually in a theatrical setting. In traditional opera, singers do two types of singing: recitative, a speech-inflected style and arias, a more melodic style. Opera incorporates many of the elements of spoken theatre, such as acting, scenery, and costumes and sometimes includes dance. The performance is typically given in an opera house, accompanied by an orchestra or smaller musical ensemble, which since the early 19th century has been led by a conductor., 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 perfect fifths, and is most commonly played by drawing a bow across its strings, though it can also be played by plucking the strings with the fingers (pizzicato). Violins are important instruments in a wide variety of musical genres. They are most prominent in the Western classical tradition and in many varieties of folk music. They are also frequently used in genres of folk including country music and bluegrass music and in jazz. Electric violins are used in some forms of rock music; further, the violin has come to be played in many non-Western music cultures, including Indian music and Iranian music. The violin is sometimes informally called a fiddle, particularly in Irish traditional music and bluegrass, but this nickname is also used regardless of the type of music played on it., An orchestra is a large instrumental ensemble typical of classical music, which features string instruments such as violin, viola, cello and double bass, as well as brass, woodwinds, and percussion instruments, grouped in sections. Other instruments such as the piano and celesta may sometimes appear in a fifth keyboard section or may stand alone, as may the concert harp and, for performances of some modern compositions, electronic instruments., Theatre or theater is a collaborative form of fine art that uses live performers, typically actors or actresses, to present the experience of a real or imagined event before a live audience in a specific place, often a stage. The performers may communicate this experience to the audience through combinations of gesture, speech, song, music, and dance. Elements of art, such as painted scenery and stagecraft such as lighting are used to enhance the physicality, presence and immediacy of the experience. The specific place of the performance is also named by the word "theatre" as derived from the Ancient Greek  (théatron, "a place for viewing"), itself from  (theáomai, "to see", "to watch", "to observe")., A composer (Latin "compn"; literally "one who puts together") is a person who creates or writes music, which can be vocal music (for a singer or choir), instrumental music (e.g., for solo piano, string quartet, wind quintet or orchestra) or music which combines both instruments and voices (e.g., opera or art song, which is a singer accompanied by a pianist). The core meaning of the term refers to individuals who have contributed to the tradition of Western classical music through creation of works expressed in written musical notation (e.g., sheet music scores)., An aria (plural: "arie" , or "arias" in common usage, diminutive form arietta or ariette) in music was originally any expressive melody, usually, but not always, performed by a singer. The term became used almost exclusively to describe a self-contained piece for one voice, with or without orchestral accompaniment, normally part of a larger work. The typical context for arias is opera, but vocal arias also feature in oratorios and cantatas, sharing features of the operatic arias of their periods., A symphony is an extended musical composition in Western classical music, most often written by composers for orchestra. Although the term has had many meanings from its origins in the ancient Greek era, by the late 18th century the word had taken on the meaning common today: a work usually consisting of multiple distinct sections or movements, often four, with the first movement in sonata form. Symphonies are scored for string (violin, viola, cello and double bass), brass, woodwind, and percussion instruments which altogether number about 30100 musicians. Symphonies are notated in a musical score, which contains all the instrument parts. Orchestral musicians play from parts which contain just the notated music for their instrument. A small number of symphonies also contain vocal parts (e.g., Beethoven's Ninth Symphony)., Musical composition can refer to an original piece of music, either a song or an instrumental music piece, the structure of a musical piece, or the process of creating or writing a new song or piece of music. People who create new compositions are called composers in classical music. In popular music and traditional music, the creators of new songs are usually called songwriters; with songs, the person who writes new words for a song is the lyricist. "Composition" is the act or practice of creating a song or other piece of music. In many cultures, including Western classical music, the act of composing typically includes the creation of music notation, such as a sheet music "score", which is then performed by the composer or by other instrumental musicians or singers. In popular music and traditional music, songwriting may involve the creation of a basic outline of the song, called the lead sheet, which sets out the melody, lyrics and chord progression. In classical music, orchestration (choosing the instruments of a large music ensemble such as an orchestra which will play the different parts of music, such as the melody, accompaniment, countermelody, bassline and so on) is typically done by the composer, but in musical theatre and in pop music, songwriters may hire an arranger to do the orchestration. In some cases, a pop or traditional songwriter may not use written notation at all, and instead compose the song in her mind and then play, sing and/or record it from memory. In jazz and popular music, notable sound recordings by influential performers are given the weight that written or printed scores play in classical music., A tradition is a belief or behavior passed down within a group or society with symbolic meaning or special significance with origins in the past. Common examples include holidays or impractical but socially meaningful clothes (like lawyers' wigs or military officers' spurs), but the idea has also been applied to social norms such as greetings. Traditions can persist and evolve for thousands of yearsthe word "tradition" itself derives from the Latin "tradere" or "traderer" literally meaning to transmit, to hand over, to give for safekeeping. While it is commonly assumed that traditions have ancient history, many traditions have been invented on purpose, whether that be political or cultural, over short periods of time. Various academic disciplines also use the word in a variety of ways. , Drama is the specific mode of fiction represented in performance. The term comes from a Greek word meaning "action" (Classical Greek: , "drama"), which is derived from "to do" (Classical Greek: , "drao"). 
The two masks associated with drama represent the traditional generic division between comedy and tragedy. They are symbols of the ancient Greek Muses, Thalia, and Melpomene. Thalia was the Muse of comedy (the laughing face), while Melpomene was the Muse of tragedy (the weeping face). Considered as a genre of poetry in general, the dramatic mode has been contrasted with the epic and the lyrical modes ever since Aristotle's "Poetics" (c. 335 BCE)the earliest work of dramatic theory., A musician (or instrumentalist) is a person who plays a musical instrument or is musically talented. Anyone who composes, conducts, or performs music may also be referred to as a musician. , Divertimento (from the Italian "" "to amuse") is a musical genre, with most of its examples from the 18th century. The mood of the "" is most often lighthearted (as a result of being played at social functions) and it is generally composed for a small ensemble. The term is used to describe a wide variety of secular (non-religious) instrumental works for soloist or chamber ensemble. It is usually a kind of music entertainment, although it could also be applied to a more serious genre. After 1780, the term generally designated works that were informal or light.
Genre.
As a separate genre, it appears to have no specific form, although most of the "divertimenti" of the second half of the 18th century go either back to a dance suite approach (derived from the 'ballet' type of theatrical "divertimento"), or take the form of other chamber music genres of their century (as a continuation of the merely instrumental theatrical "divertimento"). There are many other terms which describe music similar to the "divertimento", including "serenade", "cassation", "notturno", "Nachtmusik"; after about 1780, the "divertimento" was the term most commonly applied to this light, "after-dinner" and often outdoor music. "Divertimenti" have from one to nine movements, and there is at least one example with thirteen. The earliest publication to use the name ""divertimento"" is by Carlo Grossi in 1681 in Venice ("Il divertimento de' grandi: musiche da camera, ò per servizio di tavola") and the hint that the "divertimento" is to accompany "table service" applies to later ages as well, since this light music was often used to accompany banquets and other social events.
Examples.
Wolfgang Amadeus Mozart is known for having composed different types of "divertimenti", sometimes even taking the form of a small symphony (or, more exactly: sinfonia), for example, the "Salzburg Symphonies" K. 136, K. 137 and K. 138. Even more unusual is his six movement string trio, the Divertimento in E-flat, K. 563, which is a serious work belonging with his string quartets and quintets, despite it being labeled a "divertimento". Other composers of "divertimenti" include Leopold Mozart, Carl Stamitz, Haydn and Boccherini., Subject: list of compositions by wolfgang amadeus mozart, Relation: is_a_list_of, Options: (A) actor (B) aria (C) building (D) century (E) character (F) composer (G) concert (H) concerto (I) event (J) film (K) guitarist (L) human (M) line (N) music (O) musical (P) musical composition (Q) musical ensemble (R) musician (S) name (T) opera (U) person (V) singer (W) single (X) speech (Y) symphony (Z) system ([) term (\) theater (]) title (^) word (_) work (`) year
