Der Ring des Nibelungen [SEP] Leitmotifs
As a significant element in the "Ring" and his subsequent works, Wagner adopted the use of leitmotifs, which are recurring themes or harmonic progressions. They musically denote an action, object, emotion, character, or other subject mentioned in the text or presented onstage. Wagner referred to them in "Opera and Drama" as "guides-to-feeling", describing how they could be used to inform the listener of a musical or dramatic subtext to the action onstage in the same way as a Greek chorus did for the theatre of ancient Greece.
