The first important result was the German Singspiel entitled Die Entführung aus dem Serail (1782; Abduction from the Seraglio).
Mozart's development as an opera composer between 1781 and his death is even more remarkable, perhaps, since the problems of opera were more far-ranging than those of the larger instrumental forms and provided less adequate models. The first important result was the German Singspiel entitled Die Entführung aus dem Serail (1782; Abduction from the Seraglio). Mozart then turned to Italian opera. Mozart produced his three greatest Italian operas: Le nozze di Figaro (1786; The Marriage of Figaro), Don Giovanni(1787, for Prague), and Cosi fan tutte (1790). In his last opera, The Magic Flute (1791), Mozart turned back to German opera, and he produced a work combining many strands of popular theater and including musical expressions ranging from folk to opera.
