Piano Sonata D major K. 284 (205b)

The Sonata in D major is the last of the Six Sonatas K. 279–284 that Mozart had in his luggage when he set off for Paris in September 1777. He had already successfully performed this music in Munich, Augsburg and Mannheim, a fact he proudly told his father back at home.

He gave the works particularly rich dynamic markings and also found unusual solutions concerning their formal aspect, for instance having a slow Rondeau en Polonaise as the middle movement of the Sonata in D major. The six sonatas, which were previously only published together in the complete volumes (HN 1 and 3), are now all available as single editions with new prefaces.
