Step-by-step explanation:
Richard Wagner's term for a dramatic work in which music, drama, poetry, scenic design, staging, action, and music all work together towards one artistic expression is Gesamtkunstwerk.
This concept envisions a complete synthesis of all these arts, creating a unified and immersive experience for the audience.
