Task: Question Answering
Input (English): Context: A computer is a device that can be instructed to carry out an arbitrary set of arithmetic or logical operations automatically. The ability of computers to follow a sequence of operations, called a "program", make computers very flexible and useful. Such computers are used as control systems for a very wide variety of industrial and consumer devices. This includes simple special purpose devices like microwave ovens and remote controls, factory devices such as industrial robots and computer assisted design, but also in general purpose devices like personal computers and mobile devices such as smartphones. The Internet is run on computers and it connects millions of other computers., In physics, resonance is a phenomenon in which a vibrating system or external force drives another system to oscillate with greater amplitude at a specific preferential frequency.
Frequencies at which the response amplitude is a relative maximum are known as the system's resonant frequencies or resonance frequencies. At resonant frequencies, small periodic driving forces have the ability to produce large amplitude oscillations, due to the storage of vibrational energy., David Behrman (born August 16, 1937 in Salzburg, Austria) is an American composer and a pioneer of computer music. In the early 1960s he was the producer of Columbia Records' "Music of Our Time" series, which included the first recording of Terry Riley's "In C". In 1966 Behrman co-founded Sonic Arts Union with fellow composers Robert Ashley, Alvin Lucier and Gordon Mumma. He wrote the music for Merce Cunningham's dances "Walkaround Time" (1968), "Rebus" (1975), "Pictures" (1984) and "Eyespace 40" (2007)., Sound installation (related to sound art and sound sculpture) is an intermedia and time based art form. It is an expansion of an art installation in the sense that it includes the sound element and therefore the time element. The main difference with a sound sculpture is that a sound installation has a three-dimensional space and the axes with which the different sound objects are being organized are not exclusively internal to the work, but also external. A work of art is an installation only if it makes a dialog with the surrounding space. A sound installation is usually a site-specific but sometimes it can be readapted to other spaces. It can be made either in close or open spaces, and context is fundamental to determine how a sound installation will be aesthetically perceived.
The difference between a regular art installation and a sound installation is that the later one has the time element, which gives the visiting public the possibility to stay a longer time due possible curiosity over the development of sound. This temporal factor also gives the audience the excuse to explore the space thoroughly due to the dispositions of the different sounds in space., Alvin Lucier (born May 14, 1931) is an American composer of experimental music and sound installations that explore acoustic phenomena and auditory perception. A long-time music professor at Wesleyan University, Lucier was a member of the influential Sonic Arts Union, which included Robert Ashley, David Behrman, and Gordon Mumma. Much of his work is influenced by science and explores the physical properties of sound itself: resonance of spaces, phase interference between closely tuned pitches, and the transmission of sound through physical media., A song, most broadly, is a single (and often standalone) work of music that is typically intended to be sung by the human voice with distinct and fixed pitches and patterns using sound and silence and a variety of forms that often include the repetition of sections. Written words created specifically for music or for which music is specifically created, are called lyrics. If a pre-existing poem is set to composed music in classical music it is an art song. Songs that are sung on repeated pitches without distinct contours and patterns that rise and fall are called chants. Songs in a simple style that are learned informally are often referred to as folk songs. Songs that are composed for professional singers who sell their recordings or live shows to the mass market are called popular songs. These songs, which have broad appeal, are often composed by professional songwriters, composers and lyricists. Art songs are composed by trained classical composers for concert or recital performances. Songs are performed live and recorded on audio or video (or in some, cases, a song may be performed live and simultaneously recorded). Songs may also appear in plays, musical theatre, stage shows of any form, and within operas., Kid Millions (1934) is an American musical film directed by Roy Del Ruth, produced by Samuel Goldwyn Productions, and starring Eddie Cantor. Its elaborate "Ice Cream Fantasy Finale" production number was filmed in three-strip Technicolor, one of the earliest uses of that process in a feature-length film., The guitar is a musical instrument classified as a string instrument with anywhere from four to 18 strings, usually having six. The sound is projected either acoustically, using a hollow wooden or plastic and wood box (for an acoustic guitar), or through electrical amplifier and a speaker (for an electric guitar). It is typically played by strumming or plucking the strings with the fingers, thumb and/or fingernails of the right hand or with a pick while fretting (or pressing against the frets) the strings with the fingers of the left hand. 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. The modern guitar was preceded by the gittern, the vihuela, the four-course Renaissance guitar, and the five-course baroque guitar, all of which contributed to the development of the modern six-string instrument., Gordon Mumma (born March 30, 1935, in Framingham, Massachusetts) is an American composer. He is known most for his work with electronics, many devices of which he builds himself, and for his performances on horn., Latin (Latin: ) is a classical language belonging to the Italic branch of the Indo-European languages. The Latin alphabet is derived from the Etruscan and Greek alphabets., The Renaissance was a period in European history, from the 14th to the 17th century, regarded as the cultural bridge between the Middle Ages and modern history. It started as a cultural movement in Italy in the Late Medieval period and later spread to the rest of Europe, marking the beginning of the Early Modern Age., An art song is a vocal music composition, usually written for one voice with piano accompaniment, and usually in the classical art music tradition. By extension, the term "art song" is used to refer to the collective genre of such songs (e.g., the "art song repertoire"). An art song is most often a musical setting of an independent poem or text, "intended for the concert repertory" "as part of a recital or other relatively formal social occasion". While many pieces of vocal music are easily recognized as art songs, others are more difficult to categorize. For example, a wordless vocalise written by a classical composer is sometimes considered an art song and sometimes not., Wesleyan University (or ) is a private liberal arts college in Middletown, Connecticut, founded in 1831. Wesleyan is a Baccalaureate College that emphasizes undergraduate instruction in the arts and sciences, grants research master's degrees in many academic disciplines, and grants PhD degrees in biology, chemistry, mathematics and computer science, molecular biology and biochemistry, music, and physics., Music is an art form and cultural activity whose medium is sound and silence, which exist in time. The common elements of music are pitch (which governs melody and harmony), rhythm (and its associated concepts tempo, meter, and articulation), dynamics (loudness and softness), and the sonic qualities of timbre and texture (which are sometimes termed the "color" of a musical sound). Different styles or types of music may emphasize, de-emphasize or omit some of these elements. Music is performed with a vast range of instruments and vocal techniques ranging from singing to rapping; there are solely instrumental pieces, solely vocal pieces (such as songs without instrumental accompaniment) and pieces that combine singing and instruments. The word derives from Greek  ("mousike"; "art of the Muses"). In its most general form, the activities describing music as an art form include the production of works of music (songs, tunes, symphonies, and so on), the criticism of music, the study of the history of music, and the aesthetic examination of music. Ancient Greek and Indian philosophers defined music as tones ordered horizontally as melodies and vertically as harmonies. Common sayings such as "the harmony of the spheres" and "it is music to my ears" point to the notion that music is often ordered and pleasant to listen to. However, 20th-century composer John Cage thought that any sound can be music, saying, for example, "There is no noise, only sound.", The Internet is the global system of interconnected computer networks that use the Internet protocol suite (TCP/IP) to link devices worldwide. It is a "network of networks" that consists of private, public, academic, business, and government networks of local to global scope, linked by a broad array of electronic, wireless, and optical networking technologies. The Internet carries an extensive range of information resources and services, such as the inter-linked hypertext documents and applications of the World Wide Web (WWW), electronic mail, telephony, and peer-to-peer networks for file sharing., The Baroque guitar (c. 16001750) is a string instrument with five courses of gut strings and moveable gut frets. The first (highest pitched) course sometimes used only a single string., A chordophone is a musical instrument that makes sound by way of a vibrating string or strings stretched between two points. It is one of the four main divisions of instruments in the original Hornbostel-Sachs scheme of musical instrument classification., 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., A choir (also known as a chorale or chorus) is a musical ensemble of singers. Choral music, in turn, is the music written specifically for such an ensemble to perform. Choirs may perform music from the classical music repertoire, which spans from the Medieval era to the present, and/or popular music repertoire. Most choirs are led by a conductor, who leads the performances with arm and face gestures., Vocal music is a type of music performed by one or more singers, with or without instrumental accompaniment (a cappella), in which singing provides the main focus of the piece. Music which employs singing but does not feature it prominently is generally considered instrumental music (e.g. the wordless women's choir in the final movement of Holst's The Planets) as is music without singing. Music without any non-vocal instrumental accompaniment is referred to as "a cappella"., A microwave oven (commonly referred to as a microwave) is a kitchen appliance that heats and cooks food by exposing it to microwave radiation in the electromagnetic spectrum. This induces polar molecules in the food to rotate and produce thermal energy in a process known as dielectric heating. Microwave ovens heat foods quickly and efficiently because excitation is fairly uniform in the outer of a homogeneous, high water content food item; food is more evenly heated throughout (except in heterogeneous, dense objects) than generally occurs in other cooking techniques., Nylon is a generic designation for a family of synthetic polymers, more specifically aliphatic or semi-aromatic polyamides. They can be melt-processed into fibers, films or shapes. The first example of nylon (nylon 6,6) was produced on February 28, 1935, by Wallace Carothers at DuPont's research facility at the DuPont Experimental Station. Nylon polymers have found significant commercial applications in fibers (apparel, flooring and rubber reinforcement), in shapes (molded parts for cars, electrical equipment, etc.), and in films (mostly for food packaging).<ref name="Materials/Polyamide"></ref>, A smartphone is a mobile phone (also known as cell phones or cell mobiles) with an advanced mobile operating system that combines features of a personal computer operating system with other features useful for mobile or handheld use. Smartphones, which are usually pocket-sized, typically combine the features of a mobile phone, such as the abilities to place and receive voice calls and create and receive text messages, with those of other popular digital mobile devices like personal digital assistants (PDAs), such as an event calendar, media player, video games, GPS navigation, digital camera and digital video camera. Smartphones can access the Internet and can run a variety of third-party software components ("apps" from Google Play, Apple App Store, etc). They typically have a color display with a graphical user interface that covers more than 76% of the front surface. The display is almost always a touchscreen and sometimes additionally a touch-enabled keyboard like the Priv/Passport BlackBerrys, which enables the user to use a virtual keyboard to type words and numbers and press onscreen icons to activate "app" features., 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., A control system manages, commands, directs or regulates the behaviour of other devices or systems. It can range from a home heating controller using a thermostat controlling a domestic boiler to large Industrial control systems which are used for controlling processes or machines. , 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)., Eddie Cantor (January 31, 1892  October 10, 1964), born Edward Israel Iskowitz, was an American "illustrated song" performer, comedian, dancer, singer, actor, and songwriter. Familiar to Broadway, radio, movie, and early television audiences, this "Apostle of Pep" was regarded almost as a family member by millions because his top-rated radio shows revealed intimate stories and amusing anecdotes about his wife Ida and five daughters. Some of his hits include "Makin' Whoopee", "Ida", "Yes! We Have No Bananas", "If You Knew Susie", "Ma! He's Makin' Eyes at Me", "Baby", "Margie", and "How Ya Gonna Keep 'em Down on the Farm (After They've Seen Paree)?" He also wrote a few songs, including "Merrily We Roll Along", the "Merrie Melodies" Warner Bros. cartoon theme., A fret is a raised element on the neck of a stringed instrument. Frets usually extend across the full width of the neck. On most modern western fretted instruments, frets are metal strips inserted into the fingerboard. On some historical instruments and non-European instruments, frets are made of pieces of string tied around the neck. , 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., An acoustic guitar is a guitar that produces sound acousticallyby transmitting the vibration of the strings to the airas opposed to relying on electronic amplification (see electric guitar). The sound waves from the strings of an acoustic guitar resonate through the guitar's body, creating sound. This typically involves the use of a sound board and a sound box to strengthen the vibrations of the strings., The vihuela is a guitar-shaped string instrument from 15th and 16th century Spain, Portugal and Italy, usually with five or six doubled strings., A wind quintet, also known as a woodwind quintet, is a group of five wind players (most commonly flute, oboe, clarinet, horn and bassoon). The term also applies to a composition for such a group., Sheet music is a handwritten or printed form of music notation that uses modern musical symbols to indicate the pitches (melodies), rhythms and/or chords of a song or instrumental musical piece. Like its analogs  printed books or pamphlets in English, Arabic or other languages  the medium of sheet music typically is paper (or, in earlier centuries, papyrus or parchment), although the access to musical notation since the 1980s has included the presentation of musical notation on computer screens and the development of scorewriter computer programs that can notate a song or piece electronically, and, in some cases, "play back" the notated music using a synthesizer or virtual instruments., 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., Roy Del Ruth (October 18, 1895, Philadelphia, Pennsylvania  April 27, 1961) was an American film director., David First ( born August 20 , 1953 ) is an American composer . His music most often deals with drones and interference beats , the latter aligning his music with that of Alvin Lucier . He usually plays computer or guitar and has led the World Casio Quartet , Joy Buzzers and The Notekillers which originally existed from 1977 -- 81 and reformed in 2004 . He is also a member of Matter Waves , which includes Kid Millions on drums and Bernard Gann on bass , and the music collective New Party Systems . His albums include 1991 's Resolver , instrumental pieces influenced by minimalism and 2002 's relatively pop - oriented Universary , which consists of `` songs and drones '' . More recent releases include 2010 's We 're Here to Help ( Prophase Records ) by The Notekillers and Privacy Issues , a 3 - CD set of droneworks on the XI label . In 1995 First , along with visual artist Patricia Smith created an opera , The Manhattan Book of the Dead , which was presented at La MaMa Experimental Theatre Club 's Annex Theater in 1995 and The Washaus in Potsdam , Germany in 1996 . First received a 2001 Foundation for Contemporary Arts Grants to Artists Award . In January 2012 , the music collective , New Party Systems , an ensemble containing First , released a song First wrote ( C2011 Silent Graph Music ASCAP ) , `` We Are '' -- -- an anthem for the 99 % , with a video by director , Toni Comas ., The bit is a basic unit of information in computing and digital communications. A bit can have only one of two values, and may therefore be physically implemented with a two-state device. These values are most commonly represented as either a . The term "bit" is a portmanteau of binary digit. In information theory, the bit is equivalent to the unit "shannon", named after Claude Shannon., 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., Robert Ashley (March 28, 1930  March 3, 2014) was an American composer, who was best known for his operas and other theatrical works, many of which incorporate electronics and extended techniques., Arithmetic or arithmetics (from the Greek  "arithmos", "number") is the oldest and most elementary branch of mathematics. It consists of the study of numbers, especially the properties of the traditional operations between themaddition, subtraction, multiplication and division. Arithmetic is an elementary part of number theory, and number theory is considered to be one of the top-level divisions of modern mathematics, along with algebra, geometry, and analysis. The terms "arithmetic" and "higher arithmetic" were used until the beginning of the 20th century as synonyms for "number theory" and are sometimes still used to refer to a wider part of number theory., The gittern was a relatively small gut strung round-backed instrument that first appears in literature and pictorial representation during the 13th century in Western Europe (Iberian Peninsula, Italy, France, England). It is usually depicted played with a quill plectrum, as we can see clearly beginning in manuscript illuminations from the thirteenth century. 
It was also called the guitarra in Spain, guiterne or guiterre in France, the chitarra in Italy and quintern in Germany. A popular instrument with court musicians, minstrels, and amateurs, the gittern is considered ancestral to the modern guitar; possibly other instruments like the mandore and gallichon., An amplifier, electronic amplifier or (informally) amp is an electronic device designed to increase the value of a signal. The amount of increase, as a ratio of the output signal over input signal is called the gain of the amplifier. The signal is often a voltage, electric current or power signal. The input and output signal must not necessaraly be of the same type. An amplifier is the opposite of an attenuator: while an amplifier provides gain, an attenuator provides loss., In consumer electronics, a remote control is a component of an electronic device such as a television set, DVD player, or other home appliance, used to operate the device wirelessly from a short distance. Remote control is primarily a convenience feature for the consumer, and can allow operation of devices that are out of convenient reach for direct operation of controls. In some cases, remote controls allow a person to operate a device that they otherwise would not be able to reach, as when a garage door opener is triggered from outside or when a Digital Light Processing projector that is mounted on a high ceiling is controlled by a person from the floor level., The Sonic Arts Union was a collective of experimental musicians that was active between 1966 and 1976. The founding members of the group were Robert Ashley, David Behrman, Alvin Lucier and Gordon Mumma, all of whom had worked together in the instrumental performances of the ONCE festivals. They initially toured under the name Sonic Arts Group, until, at Ashley's suggestion, the name was changed to Sonic Arts Union., A personal computer (PC) is a multi-purpose electronic computer whose size, capabilities, and price make it feasible for individual use. PCs are intended to be operated directly by a person using a graphical user interface such as Windows. The versatility of a personal computer is greatly enhanced by the use of peripheral devices such as a keyboard, monitor, printer, mouse, speakers, and an external hard drive., An electric guitar is a fretted string instrument that uses a pickup to convert the vibration of its stringswhich are typically made of steel, and which occurs when a guitarist strums, plucks or fingerpicks the stringsinto electrical signals. The vibrations of the strings are sensed by a pickup, of which the most common type is the magnetic pickup, which uses the principle of direct electromagnetic induction. The signal generated by an electric guitar is too weak to drive a loudspeaker, so it is plugged into a guitar amplifier before being sent to a loudspeaker, which makes a sound loud enough to hear. The output of an electric guitar is an electric signal, and the signal can easily be altered by electronic circuits to add "color" to the sound or change the sound. Often the signal is modified using effects such as reverb and distortion and "overdrive", with the latter being a key element of the sound of the electric guitar as it is used in blues and rock music., Experimental music is a compositional practice defined broadly by exploratory sensibilites and movement radically opposed to and questioning of institutionalized musical compositional, performing, and aesthetic conventions . The practice became prominent in the mid-20th century, particularly in North America. John Cage was one of the earliest composers to use the term and one of experimental music's primary innovators, utilizing indeterminacy techniques and seeking unknown outcomes. In France, as early as 1953, Pierre Schaeffer had begun using the term """" to describe compositional activities that incorporated tape music, musique concrète, and elektronische Musik. Also, in America, a quite distinct sense of the term was used in the late 1950s to describe computer-controlled composition associated with composers such as Lejaren Hiller., An instrumental is a musical composition or recording without lyrics, or singing, although it might include some inarticulate vocals, such as shouted backup vocals in a Big Band setting. The music is primarily or exclusively produced by musical instruments. An instrumental can exist in music notation, after it is written by a composer; in the mind of the composer (especially in cases where the composer herself will perform the piece, as in the case of a blues solo guitarist or a folk music fiddle player); as a piece that is performed live by a single instrumentalist or a musical ensemble, which could range in size from a duo or trio to a large Big Band, concert band or orchestra., Samuel Goldwyn Productions was an American film production company founded by Samuel Goldwyn in 1923, and active through 1959. Personally controlled by Goldwyn and focused on production rather than distribution, the company developed into the most financially and critically successful independent production company in Hollywood's Golden Age., A mobile device (or handheld computer) is a small computing device, typically, small enough to hold and operate in the hand and having an operating system capable of running mobile apps. These may provide a diverse range of functions. Typically, the device will have a display screen with a small numeric or alphanumeric keyboard or a touchscreen providing a virtual keyboard and buttons (icons) on-screen. Many such devices can connect to the Internet and interconnect with other devices such as car entertainment systems or headsets via Wi-Fi, Bluetooth or near field communication (NFC). Integrated cameras, digital media players, mobile phone and GPS capabilities are common. Power is typically provided by a lithium battery. , Music notation or musical notation is any system used to visually represent aurally perceived music played with instruments or sung by the human voice through the use of written, printed, or otherwise-produced symbols, including ancient symbols or modern musical symbols and including ancient symbols cut into stone, made in clay tablets or made using a pen on papyrus, parchment or manuscript paper; printed using a printing press (ca. 1400s), a computer printer (ca. 1980s) or other printing or modern copying technology. Types and methods of notation have varied between cultures and throughout history, and much information about ancient music notation is fragmentary. Even in the same time period, such as in the 2010s, different styles of music and different cultures use different music notation methods; for example, for professional classical music performers, sheet music using staves and note heads is the most common way of notating music, but for professional country music session musicians, the Nashville Number System is the main method., Subject: david first, Relation: place_of_birth, Options: (A) 11th century (B) ashley (C) band (D) best (E) box (F) bridge (G) central (H) columbia (I) france (J) germany (K) golden (L) gordon (M) hard (N) harmony (O) hollywood (P) home (Q) horn (R) iberian (S) iberian peninsula (T) israel (U) liberal (V) light (W) made (X) march (Y) massachusetts (Z) middletown ([) mobile (\) most (]) of (^) once (_) peer (`) philadelphia (a) price (b) roy (c) ruth (d) salzburg (e) shannon (f) spain (g) terry (h) time (i) tradition (j) union (k) wallace (l) wood
