'''''Zaide''''' (originally, ''Das Serail'') is an unfinished opera, K. 344, written by Wolfgang Amadeus Mozart in 1780. Emperor Joseph II, in 1778, was in the process of setting up an opera company for the purpose of performing German opera. One condition required of the composer to join this company was that he should write a comic opera. At Salzburg in 1779 Mozart began work on a new opera (now known as ''Zaide'' although Mozart did not give it such a title). It contains spoken dialogue, which also classifies it as a ''Singspiel'' (literally, "singing play"). Only the arias and ensembles from the first two acts were composed. Missing are an overture and third act.
It was popular at the time for operas to depict the rescue of enslaved Westerners from Muslim courts, since Muslim pirates were preying on Mediterranean shipping, particularly to obtain slaves for various purposes. This story portrays Zaide's effort to save her beloved, Gomatz.
Mozart was composing for a German libretto by Johann Andreas Schachtner, set in Turkey, which was the scene of his next, completed rescue Singspiel (''Die Entführung aus dem Serail''). He soon abandoned ''Zaide'', to work on ''Idomeneo'', and never returned to the project. The work was lost until after his death, when Constanze Mozart, his wife, found it in his scattered manuscripts in 1799. The fragments wouldn't be published until 1838, and its first performance was held in Frankfurt on January 27, 1866, the 110th anniversary of Mozart's birth. ''Zaide'' has since been said to be the foundations of a masterpiece, and received critical acclaim. The tender soprano air, "Ruhe sanft, mein holdes Leben" is the only number that might be called moderately familiar.
The title ''Zaide'' was supplied by the Mozart researcher Johann Anton André, who first published the score, including his own completion of it, in the 1830s.[http://www.sfsymphony.org/Watch-Listen-Learn/Read-Program-Notes/Program-Notes/MOZART-Three-Arias-from-Zaide,-K-344-336b.aspx San Francisco Symphony].

Modern companion pieces to'' Zaide'' have been written by both Luciano Berio and Chaya Czernowin.
In modern performances, Mozart's Symphony No. 32, K. 318, which was composed around the same time as ''Zaide'' and later used as an overture to Francesco Bianchi's ''La villanella rapita'' (1784), is often given as an overture to ''Zaide''. Completions of the opera may use a pastiche of Mozart's concert arias or, more popularly, music from ''Thamos, King of Egypt'', also from the same period of Mozart's career.
