Mozart Piano Sonata G major K. 283 (189h)

FIRST MOVEMENT The fifth sonata K 283 (189h), in the pastoral and joyous key of G major, is especially popular; it again displays novel ideas, musically and pianistically. The diversity of its melodic invention is highly typical of Mozart, and so is the clear-cut sonata form of the first movement. The very first idea is a marvel of folkmusic-like invention. The opening theme and its continuation is an interplay of question and answer with the final response in baroque hemiola rhythm (a sudden 3/2 meter interpolated in a 3/4 movement). The ornamented unison passage which follows (mm. 16-22) is superbly written and sounds especially brilliant and full-bodied on the pianos of Mozart�s time. This tutti effect was one of his favourites, and he also used it in later works, such as the Variation on a Theme by Gluck K 455 the Piano Concerto K 456/I and the cadenza of the Piano Concerto in G major K 453/I.
