The oft-told but now questionable story of the origins of this work is that Beethoven at first refused categorically to participate in Diabelli's project, dismissing the theme as banal, a "Schusterfleck" or 'cobbler's patch,' unworthy of his time. Not long afterwards, according to the story, upon learning that Diabelli would pay a handsome price for a full set of variations from him, Beethoven changed his mind and decided to show how much could be done with such slim materials. (In another version of the legend, Beethoven was so insulted at being asked to work with material he considered beneath him that he wrote 33 variations to demonstrate his prowess.) Today, however, this story is taken as more legend than fact. Its origins are with Anton Schindler, Beethoven's unreliable biographer, whose account conflicts in a number of ways with several established facts, indicating that he did not have first-hand knowledge of events.
