Chamber music: Piano matinee Paul Lewis
In 1819, the esteemed Viennese composer and publisher Anton Diabelli commissioned several renowned composers to write him a piece based on a small waltz composed by him. He intended to publish these pieces in an anthology for charitable purposes. Among them were Franz Schubert, Carl Czerny, Mozart's son Franz Xaver and even Archduke Rudolph. Almost all of the 51 composers who followed Diabli's call wrote a variation. Four years later, however, Beethoven presented a monumental work comprising 33 variations and lasting almost an hour, which, along with Bach's "Goldberg Variations", is one of the greatest achievements of the piano literature.
