Beethoven's Diabelli Variations as comic parody
The publisher Anton Diabelli asked many Viennese composers to each write one variation on his banal waltz. Beethoven instead wrote 33, treating the tune as material to mock, distort and transcend; Variation 22, for instance, quotes Leporello's grumbling 'Notte e giorno faticar' from Mozart's Don Giovanni. Brendel reads the cycle as one of music's great humorous works, showing that trivial source material can drive a masterpiece when the composer comments on it rather than decorating it.
