the number of movements in a symphony usually is
Symphony 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.[20] 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[21] and Mahler.[citation needed] 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.[22]
Messiah (Handel) The three-part structure of the work approximates to that of Handel's three-act operas, with the "parts" subdivided by Jennens into "scenes". Each scene is a collection of individual numbers or "movements" which take the form of recitatives, arias and choruses.[15] There are two instrumental numbers, the opening Sinfony[n 2] in the style of a French overture, and the pastoral Pifa, often called the "pastoral symphony", at the mid-point of Part I.[18]
