Opera in German is the opera of the German-speaking countries. These include Germany, Austria, and the German states that preceded those countries.
German-language opera appeared remarkably quickly after the birth of opera itself in Italy. The first Italian opera was Jacopo Peri's Dafne of 1598. In 1627, Heinrich Schütz provided the music for a German translation of the same libretto. Yet during much of the 17th and 18th centuries German-language opera would struggle to emerge from the shadow of its Italian-language rival, with leading German-born composers such as Handel and Gluck opting to work in foreign traditions such as opera seria.
Some Baroque composers, such as Reinhard Keiser, did try to challenge Italian dominance, and the theatre principal Abel Seyler became an eager promoter of German opera in the 1770s, but it was only with the appearance of Mozart that a lasting tradition of serious German-language opera was established. Mozart took the simple, popular genre of Singspiel and turned it into something far more sophisticated. Beethoven followed his example with the idealistic Fidelio; and with Der Freischütz of 1821, Weber established a uniquely German form of opera under the influence of Romanticism. Weber's innovations were eclipsed by those of Richard Wagner, one of the most revolutionary and controversial figures in musical history. Wagner strove to achieve his ideal of opera as "music drama", eliminating all distinction between aria and recitative, employing a complex web of leitmotifs and vastly increasing the power and richness of the orchestra. Wagner also drew on Germanic mythology in his huge operatic cycle Der Ring des Nibelungen.
