Wagner's music helps the drama in "Das Rheingold."

"The composer even went to Munich -- only to discover that his entrance in the rehearsals was forbidden. Back to Tribschen (close to Lucerne Lake, in Switzerland), where he lived, Wagner wrote a threatening letter to Franz Wüllner, the conductor that replaced Richter: 'Take off your hands of my scores! Take my advice, mister, or go to hell!'. He later added with his characteristic arrogance: 'People like yourself must take a lot of classes from a man like me until understand that you are not capable of understanding anything'." (Perpetuo)
