Mozart added the work to his catalogue on June 26, 1788, the same date as his Symphony No. 39. A typical performance takes about 14 minutes. Although it is well-known piece today, it was not published in Mozart's lifetime, and it first appeared in print in 1805.","movements":"","composer":{"id":11,"url":"https://api.musopen.org/v2/composers/11/","slug":"wolfgang-amadeus-mozart","first_name":"Wolfgang Amadeus","last_name":"Mozart","date_of_birth":"27th January 1756","place_of_birth":"Salzburg, Austria","date_of_death":"5th December 1791","description":"Wolfgang Amadeus Mozart (baptised Johannes Chrysostomus Wolfgangus Theophilus Mozart) was an influential composer of the Classical era, who showed prodigious ability from his earliest childhood. Competent on keyboard and violin, he composed from the age of five and performed before European royalty. At 17, he was engaged as a court musician in Salzburg, though he later moved to Vienna, where he achieved fame but little financial security. During his final years in Vienna, he composed many of his best-known symphonies, concertos, and operas, and portions of the Requiem, which was largely unfinished at the time of his death. The circumstances of his early death have been much mythologized. He composed over 600 works, many acknowledged as pinnacles of symphonic, concertante, chamber, operatic, and choral music. He is among the most enduringly popular composers, and his influence on subsequent Western music is profound; Beethoven composed his own early works in the shadow of Mozart, and Haydn wrote that \"posterity will not see such a talent again in 100 years.\"\n","image":"https://s.musopen.org/media/images/composers/Wolfgang-amadeus-mozart_1-revert.jpg","is_featured":true,"is_bookmarked":false},"form":{"id":15,"url":"https://api.musopen.org/v2/forms/15/","slug":"sonata","name":"Sonata","description":"A sonata is a work in three or four movements (rarely two, or more than four) for a single instrument or a small number of performers. The term evolved through the history of music, designating a variety of forms prior to the Classical era. By the early 19th century the word came to define a multi movement work, almost always including a first movement in the so called 'sonata form', a second movement of a slow, contrasting character; a dance for third movement, and a finale in a rondo, theme and variations, or sonata form. The term 'sonata form' refers to the layout of the first movement of a sonata, which confronts two main themes of different quality, develops them and then recapitulates. This soon became a basic principle in academic music writing. It was applied to many forms of large works, and, together with the fugue, defined the composition and musical analysis procedures for almost a century. Today it is still widely studied, and sonatas continued to be written, even if musical languages have changed.","is_bookmarked":false},"period":{"id":3,"url":"https://api.musopen.org/v2/periods/3/","slug":"classical","name":"Classical","description":"The Classical period of Western academic music is usually accepted to range from around 1750 to the late 1810's. It followed from the Baroque period and was in turn succeeded by the Romantic era. Music became generally lighter in terms of textural density, emphasizing elegance in place of the Baroque's serious and dramatic delivery. This resulted in a clearer tonal structure emerging from compositions. Though the style became arguably less passionate, the use of contrast became more pronounced than before. Instrumental music gained importance, and the orchestra grew in size and consolidated, approximating its modern form. The harpsichord was eventually replaced by the pianoforte, and many solo and chamber genres emerged, of which the sonata developed the most. In general terms, the Classical period can be defined as the time when most of the modern musical concepts consolidated. The best known composers from this period are Joseph Haydn, Wolfgang Amadeus Mozart, Ludwig van Beethoven, and Franz Schubert; other notable names include Muzio Clementi, Antonio Salieri,  Carl Philipp Emanuel Bach, and Christoph Willibald Gluck. Beethoven, and sometimes Schubert, have been traditionally regarded as transitional figures between the Classical and Romantic periods. The term 'classical music' is often used colloquially to define all Western academic music.","is_bookmarked":false},"instruments":[{"id":37,"url":"https://api.musopen.org/v2/instruments/37/","slug":"piano","name":"Piano","description":"The piano is a keyboard-based music instrument. Its versatility and pervasiveness, together with its polyphonic capabilities have made it one of the world's most employed instruments, and a crucial piece in the development of the Western musical tradition. It's name is a shortened form of 'pianoforte', terms which in Italian respectively mean 'soft' and 'loud', referring the fact that the pianoforte had the capability of producing variations in volume which previous keyboard instruments could not.\r\nStandard pianos have 52 white keys and 36 black ones, for a total of 88. They are chordophones: pressing any key activates a mechanism which makes a hammer strike a set of strings. The sound produced is amplified via the soundboard and body of the piano. \r\nBeing one of the most influential instruments in the history of music, the piano has undergone many changes and technological innovations, from the insertion of the damper and tonal pedals, to the creation of electric, electronic, and digital pianos.","image":"https://s.musopen.org/media/images/instruments/pexels-juan-pablo-serrano-arenas-1246437_1.jpg","is_bookmarked":false}],"key":{"id":1,"url":"https://api.musopen.org/v2/keys/1/","slug":"c-major","name":"C Major","is_bookmarked":false},"licenses":["CC-BY-NC","CC-PD"],"avg_duration":9,"practice_difficulty":"medium","rcm_difficulty_level":"","rating":3.85,"hits":278192,"is_bookmarked":false},"key":null,"instruments":[],"rating":0.0,"fileurl":"https://dl.musopen.org/sheetmusic/bf9a6c96-f669-4d26-ad5b-f6e6164615c7.pdf?filename=Piano%20Sonata%20no.%2016%20%27Facile%27%2C%20K.%20545%20-%20Complete%20Score%20%28Martienssen-Weismann%29.pdf","is_bookmarked":false}
