Wolfgang Amadeus Mozart's Piano Sonata No. 6 in D major, K. 284 / 205b, (1775) is a sonata in three movements:

A typical performance takes about 20 to 25 minutes.

This piano sonata is the last of the sonatas that Mozart composed in Munich. The piece is subtitled "Dürnitz," as it was written for Baron von Dürnitz, an amateur bassoonist and keyboard-player, who failed to pay for the work. The work was written during Mozart's stay in Munich from December 1774 to March 1775 for the production of La finta giardiniera. It is the only one of Mozart's six Munich piano sonatas to be published in his lifetime, ten years later.^[1]

The autograph and the first edition of the sonata have numerous inconsistencies.
