These sonatas date from the final part of Mozart’s life, when he was in his early thirties and at the height of his genius. Having recently entered into Freemasonry, Mozart, who had shaken off the paternal yoke and authority of the Prince-Archbishop of Salzburg, was living in Vienna, and it was in Vienna that he composed these two Sonatas. Mozart’s music, whether expressive or energetic, light, fierce, elegant or austere, reveals the expectations, the hopes and the dramas that characterised his life.
