paragraph_text: Wolfgang Amadeus Mozart completed his Symphony No. 41 in C major, K. 551, on 10 August 1788. The longest and last symphony that he composed, it is regarded by many critics as among the greatest symphonies in classical music.

paragraph_text: Although Melartin was chiefly a lyricist, the symphony was central to his musical output. He wrote six symphonies (1902–1924) and was the first Finnish composer to bear Mahler's influence. The fourth symphony uses a vocalise like that of Carl Nielsen's "Sinfonia Espansiva". The fifth is a "Sinfonia brevis" ending in a fugue and chorale, while the sixth, harmonically more advanced than the other five, advances stepwise from a C minor first movement – with evocations of Mahler's second symphony – to an E-flat major finale. His musical output also includes an opera, "Aino" (based on the character from the Finnish national epic), a violin concerto, four string quartets, and many piano pieces. His works therefore are divided mainly into large-scale works for orchestra, and chamber pieces for much smaller groups and soloists. Despite working in the same time period as Jean Sibelius he was not influenced by the more famous composer's style, and his work has been largely overshadowed by that of Finland's most revered composer.

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.

The symphony K. 96 is given the number 46 in this numbering scheme.
