paragraph_text: In his native Poland, in France, where he composed most of his works, and beyond, Chopin's music, his status as one of music's earliest superstars, his association (if only indirect) with political insurrection, his love life and his early death have made him, in the public consciousness, a leading symbol of the Romantic era. His works remain popular, and he has been the subject of numerous films and biographies of varying degrees of historical accuracy.

paragraph_text: This work was only known to Ludwig Ritter von Köchel as an incipit in the catalogue of Breitkopf & Härtel, and thus it was placed in the Anhang as K. Anh. 214. Alfred Einstein then discovered a set of parts in the Berlin State Library with the title ""Synfonia Ex Bb...Del Sigr. cavaliere Amadeo Wolfgango Mozart Maestro di concerto di S.A. á Salisburgo"". Wolfgang became the Concertmaster to the Archbishop of Salzburg in November 1769, and was given the title "cavaliere" in July 1770, but as this is a later copy, this information cannot be used for dating purposes. Einstein believed the symphony to date from early 1768 on stylistic grounds; Neal Zaslaw and Gerhard Allroggen believe even earlier dates to also be possible, and Zaslaw dated the symphony cautiously to Salzburg in 1767. Einstein also believed that the symphonies in the catalogue of Breitkopf & Härtel were sent by Leopold Mozart to be published.

paragraph_text: At the beginning of the 19th century, Beethoven elevated the symphony from an everyday genre produced in large quantities to a supreme form in which composers strove to reach the highest potential of music in just a few works. Beethoven began with two works directly emulating his models Mozart and Haydn, then seven more symphonies, starting with the Third Symphony (``Eroica '') that expanded the scope and ambition of the genre. His Symphony No. 5 is perhaps the most famous symphony ever written; its transition from the emotionally stormy C minor opening movement to a triumphant major - key finale provided a model adopted by later symphonists such as Brahms and Mahler. His Symphony No. 6 is a programmatic work, featuring instrumental imitations of bird calls and a storm; and, unconventionally, a fifth movement (symphonies usually had at most four movements). His Symphony No. 9 includes parts for vocal soloists and choir in the last movement, making it a choral symphony.
