The cycle closes with Beethoven's final sonata offering, the transcendental C Minor op.111. But before that there's the high-jinx of the early sonata op.22, the warm-heart of the E Flat op.31 no.3 and the wonderful 'Les Adieux,' one of his most clearly programmatic works.

And to finish, that great C Minor sonata, as Beethoven bids farewell to the genre that he took from Haydn and Mozart and bequeathed to the entire Romantic generation to follow.
