Symphony No. 63 was composed by which Austrian Classical composer?
Symphony No. 63 (Haydn) The Symphony No. 63 in C major, Hoboken I/63, is a symphony by Joseph Haydn written sometime between 1779 and 1781. It is often known by the title of the second movement, "La Roxelane", named for Roxelana, the influential wife of Suleiman the Magnificent of the Ottoman Empire. This second movement was originally part of Haydn's incidental music for Charles Simon Favart's stage work "Soliman der zweite" (or "Les Trois Sultanes") in which Roxelana was a character.
Symphony No. 17 (Mozart) Symphony No. 17 in G major, K. 129, is the second of three symphonies completed by Wolfgang Amadeus Mozart in May 1772, when he was 16 years old, but some of its sections may have been written earlier.
