Rondo alla Turca K. 331

The Piano Sonata in A major includes one of Mozart’s most famous melodies. It was once believed to have been composed in 1778, during Mozart’s time in Paris, but it now appears to date from around 1782. This revised dating is based on a new analysis of Mozart’s autograph manuscript and further supported by evidence from this manuscript, written in the hand of a copyist. The copyist’s version was originally derived from Mozart’s now-­ incomplete autograph and helps to supplement it. As such, it predates the printed first edition of the sonata, which was published by Artaria—along with K. 330 and 332—in August 1784.
