Symphony No. 3 (Beethoven) which the bass theme is heard as the first variation before the main theme ultimately appears. This again parallels the structure of the Opus 35 variations themselves. Finally, the loud E chord that begins the Opus 35 variations themselves is moved here to the beginning of the first movement, in the form of the two chords that introduce the first movement. Alternatively, the first movement's resemblance to the overture to the comic opera "Bastien und Bastienne" (1768), composed by twelve-year-old W. A. Mozart, has been noted. It was unlikely that Beethoven knew of that unpublished composition. A possible explanation is
Vienna State Opera of the Staatsoper. Recent examples include "Peter Pan", "" ("The Dream Gobbler"), "Der 35. Mai" ("The 35th of May"), C. F. E. Horneman's "Aladdin", "Bastien und Bastienne" and "Wagners Nibelungenring für Kinder" ("Wagner's Ring for children"). In addition to this, there is a production of "The Magic Flute" every year for 9- and 10-year-olds, decorated like the Opernball. The opera house also has an opera school for boys and girls between the ages of eight and fourteen, which takes place in the afternoons after regular school. The children are introduced to music theatre and the prospect of becoming opera singers.
