Comic opera and humour, Offenbach's works were intended solely to amuse. Though generally well crafted and full of humorous satire and grand opera parodies, plots and characters in his works were often interchangeable. Given the frenetic pace at which he worked, Offenbach sometimes used the same material in more than one opera. Another Frenchman who took up this form was Charles Lecocq (1832–1918). The singspiel developed in 18th-century Vienna and spread throughout Austria and Germany. As in the French "opéra comique", the "singspiel" was an opera with spoken dialogue, and usually a comic subject, such as Mozart's "Die Entführung aus dem Serail
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.
