Beethoven's Diabelli Variations represent one of the greatest works for solo piano ever to be written. Throughout this monumental work, Beethoven dazzles us with his ability to make Diabelli's theme become anything he wants it to be. Diabelli's waltz has often been dismissed as rather primitive, even by Beethoven himself. The theme is, therefore, a wonderful example of the irrelevance of where a great composer's musical material comes from, and the corresponding importance of how the composer manipulates and develops that material. Just as composers of the Renaissance could build profound Mass settings from trivial secular tunes, so Beethoven develops a vast musical edifice from an apparently unlikely source. For award-winning pianist Muriel Chemin, these variations are really "transformations" and, alongside Beethoven's sonatas, have become an integral part of her repertoire. She is considered one of the most convincing and original interpreters of Beethoven and Mozart, described by Hebdo National as: "Simply one of the best interpreters of Beethoven in the world."
