His 18 piano sonatas can be described as the secret stars of Wolfgang Amadeus Mozart's extensive oeuvre. They were often important areas of experimentation, which in Mozart's short biography describe a development from early rococo to classical maturity, in which he explored new compositional techniques and then later transferred these to the larger genres. This is exemplified by the three works now recorded by Amy Lin in her familiar sensitive manner: the Sonata K. 333 emphasizes the lyrical and pastoral. In K. 284, the 18-year-old composer establishes the alternation between 'quasi-tutti' based on the orchestral writing and soloistic passages in dialogue-like interplay. The famous C minor Sonata K. 457, which Beethoven admired so much, shows a completely different, darkly dramatic tone and thus Mozart's fascinating stylistic diversity in this genre as well.
