In 1783 -85, Mozart wrote his Five Divertimenti for two bassett -horns and bassoon (K. 439b) , which were first published in 1803. At about the same time a version for piano duet was made which rearranged the movements of the FiveDivertimenti as Six Viennese Sonatinas. This new edition is based on the piano version of 1803, but also takes into account the original wind divertimenti and attempts to combine the original phrasing and part -writing with anidiomatic pianistic style.
