What is the most important aspect of a Wagnerian music drama?

The most important aspect of a Wagnerian music drama is the concept of "Gesamtkunstwerk," or "total work of art," where music, poetry, and visual elements are seamlessly integrated to create a unified artistic experience. Wagner emphasizes the role of leitmotifs—musical themes associated with characters, ideas, or emotions—to deepen the narrative and enhance emotional impact. This holistic approach elevates the storytelling, allowing for profound exploration of themes such as love, power, and redemption within a richly textured musical landscape.
