Mozart assembled this sonata from two parts that had been composed at different times. The Rondo K. 494 is from 1786. In January 1788, Mozart composed the two pieces K. 533, and Hoffmeister in Vienna published the three movements as a sonata. To this end he did, however, thoroughly rework the Rondo, incorporating a small fugue-like passage - perhaps to bring the finale closer to the other two movements. In its final version, the work shows how intensively Mozart had looked into the style of Bach and Handel at the time. We are now offering this sonata, included in the complete volume, as an attractive single edition with a new preface by the editor.
