Nestled between two titans - the Waldstein and the Appassionata - is an unusual, enigmatic two-movement work. Beethoven's contemporaries and later generations of critics didn't think much of it, and it remains seldom performed today. The Sonata was Beethoven's first serious look at the possibilities of a two-movement form (if we disregard the two 'for the drawer' Sonatas, Op. 49), which he went on to explore in the increasingly poetic Opp. 78, 90 and finally 111.
