on his project. At first Mozart thought he needed to finish his opera in only two months, because tentative plans were made to perform it at the September visit of the Russian Grand Duke Paul (son of Catherine the Great and heir to the Russian throne). However, it was ultimately decided to perform operas by Gluck instead, giving Mozart more time. It was around this time that Mozart articulated his views about the role of the composer and the librettist in the preparation of an opera. He wrote to his father (13 October 1781): It would seem that something along these lines did happen—that is, Mozart decided to play a major role in the shaping of the libretto, insisting that Stephanie make changes for dramatic and musical effect. On 26 September Mozart wrote: Mozart was evidently quite pleased to have in Stephanie a librettist who would listen to him. The September 26 letter also says: With the delays for rewriting, the composition took several more months. The premiere took place on 16 July 1782, at the Burgtheater in Vienna. Character Die Entführung aus dem Serail is in the genre of "Singspiel", thus the music lacks recitatives and consists entirely of set numbers. As Spike Hughes notes, the action is mostly carried forward by the spoken dialogue, so the libretto gave Mozart little opportunity to display an achievement for which his later operas are celebrated, namely the construction of scenes in which the plot is both reflected in and driven forward by the music. Die Entführung is lighthearted and frequently comic, with little of the deep character exploration or darker feelings found in Mozart's later operas. The opera was inspired by a contemporary interest in the exotic culture of the Ottoman Empire, a nation which had only recently ceased to be a military threat to Austria. Mozart's opera includes a Westernized version of Turkish music, based very loosely on the Turkish Janissary band music. Certain aspects of the opera conform to an eighteenth-century European view of orientalism. The Pasha's titular harem, for example, reprised themes of sexual libertinage. And the comically sinister overseer, Osmin, is a send-up of earlier stereotypes of Turkish despotism. However, the opera also defies the stereotype of despotic Turkish culture, since its climax entails a selfless act of forgiveness on the part of the Pasha. The music includes some of the composer's most spectacular and difficult arias.
