Final answer:
Wagner presented evidences to support his theory including themes and motifs, leitmotifs, expanded orchestra, and prolonged musical structure.
Step-by-step explanation:
Wagner presented several evidences in support of his theory.
- Themes and motifs: Wagner's operas revolved around specific themes and motifs, such as love, redemption, and the struggle between good and evil. This consistency across his works supports his theory of the Gesamtkunstwerk, or total work of art.
- Leitmotifs: Wagner's use of leitmotifs, recurring musical themes associated with specific characters, places, or ideas, further enhances the unity and coherence of his operas. This demonstrates the interconnectedness of different elements within his works, as emphasized in his theory.
- Expanded orchestra: Wagner's orchestration expanded beyond the traditional boundaries, creating a richer and more immersive musical experience. This contributes to the idea of the Gesamtkunstwerk, where music plays an integral role in conveying the narrative and emotions.
- Prolonged musical structure: Wagner's operas have prolonged musical structures, with continuous music spanning several hours. This allows for the development and exploration of complex themes and emotions, further supporting his theory of the Gesamtkunstwerk.
