supports: 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.
