Richard Wagner put his supreme effort, as well as his earnings, into constructing the perfect festival theater in the Bavarian town of Bayreuth where his masterpiece, the four-opera cycle Der Ring des Nibelungen, could be performed in a manner which would conform to his vision of how the drama should unfold. Wagner's own perception was that the unique and revolutionary character of his monumental tetralogy necessitated a special theater—one where the difficulties of staging an expansive drama could be surmounted, where changes of scene could be effected without halting the performance for vast lengths of time. Der Ring des Nibelungen, which is based on a medieval German epic, the Nibelungenlied, and Norse mythology, enlarged the expressive powers of German Romantic opera; today it also gives testimony to Wagner's willingness to venture into new areas for inspirational material. The third opera of the cycle, Siegfried, reproduced here in full score, presents the story of a youthful Germanic hero of legendary proportions, a young man without experience of fear, who slays the reptilian hoarder of ill-gotten, powerful golden treasures and rescues a banished goddess from fiery captivity. Performed during the heyday of Bismarck's Realpolitik, following decades of revolutionary and anarchic fervor, Siegfried is reputed to have social and political implications. In The Perfect Wagnerite, George Bernard Shaw discusses the opera in allegorical terms, and describes the heroic Siegfried as "a born anarchist, the ideal of Bakoonin, an anticipation of the 'overman' of Nietzsche." Whether or not the political import of Richard Wagner's alleged revolutionary thought is of concern to the music lover of modern times, the influence and power of the operas of Der Ring des Nibelungen are indisputable. The crowning achievement of German music of the Romantic era, the Ring forged a new synthesis of music and drama on the largest scale, drawing on rich literary and philosophical resources to expand the dramatic possibilities of the opera as a musical form. Reproduced from the first edition (1876), which received Wagner's final approval, this full-size full score brings Siegfried, an important opera in the Ring and one of the most performed, recorded, studied, and admired operas of the Romantic era, to Wagner enthusiasts, opera lovers, and musicians at a moderate, affordable price.
