Liebe und Eifersucht Liebe und Eifersucht Liebe und Eifersucht ("Love and Jealousy") is a "Singspiel", an opera with spoken dialogue, in three acts by the German composer and author E. T. A. Hoffmann, composed in 1807 on his own libretto based on the translation by August Wilhelm Schlegel of a play by Calderón. The opera was first published by Schott in 1999, and premiered at the 2008 Ludwigsburger Schlossfestspiele. The author Ernst Theodor Amadeus Hoffmann was interested in music, wanted originally to become a musician, and added Amadeus to his names in honour of Mozart. He composed one successful opera in 1816, "Undine",
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.
