Ludwig van Beethoven’s 32 piano sonatas form an unparalleled canon, remaining one of the greatest and most rewarding challenges for pianists to this day. These three sonatas represent Beethoven’s Early, Middle and Late periods but are united in the key of C – minor, for the dramatic and stormy intensity of mood in the Pathétique, and major for the radiant and poetic Waldstein sonata. In his sonata Op. 111 the cycle is completed with music of utmost dramatic tension and the deepest spirituality.
