Turkish Rondo

It is uncertain where and when Mozart composed the sonata; however, Vienna or Salzburg in around 1783 is currently thought to be most likely (Paris and dates as far back as 1778 have also been suggested).

The last movement, Alla Turca, popularly known as the Turkish Rondo or Turkish March, is often heard on its own and is one of Mozart's best-known piano pieces. It imitates the sound of Turkish Janissary bands, the music of which was much in vogue at that time. Various other works of the time imitate this music, including Mozart's own opera The Abduction from the Seraglio.
