Apart from his 32 piano sonatas and five piano concertos, Beethoven wrote a great number of themes with variations. And with the 33 Variations on a Waltz by Anton Diabelli he left a unique magnum opus to posterity. Finnish pianist Olli Mustonen sees it likewise: he is one of the few world-class pianists who regularly features variations by the Titan in his programmes. “Beethoven’s variations have no equivalent anywhere else in piano repertoire”, he states. Mustonen’s complete recording of the Beethoven variation cycles won the Edison Award. He has selected several of them for this evening’s recital, including the variations on “God Save the King”, the British national anthem.
