Which of the following is NOT true of Wagner's magnum opus, Der Ring des Nibelungen?

The statement about the special theatre built in Hamburg, Germany, specifically for Wagner's operas is not true. Instead, Wagner designed a specific theatre for his operas in Bayreuth, known as the Bayreuth Festspielhaus, where he could present his monumental work, Der Ring des Nibelungen, in a setting that complemented the music and drama. This theatre was purpose-built to enhance the acoustics and the overall experience of his operas.

Wagner's Der Ring des Nibelungen is indeed based on Norse mythology and Germanic legends, making use of rich storytelling rooted in historical and mythical narratives. It consists of four interconnected operas: Das Rheingold, Die Walküre, Siegfried, and Götterdämmerung, which together create an extensive and cohesive narrative. Additionally, Wagner is renowned for his innovative use of the orchestral leitmotif—musical phrases that represent characters, themes, or ideas—allowing audiences to engage with the music on a deeper, thematic level throughout the cycle. Thus, the incorrect statement about a theatre in Hamburg highlights a misunderstanding of Wagner's special relationship with the Bayreuth venue, which was central to his artistic vision.
