“An opera has to have a foundation; something big, like unhappy love, or vengeance, or some point of honor. Because people are like that, you know. There they sit, all those stockbrokers and rich surgeons and insurance men, and they look so solemn and quiet as if nothing would rouse them. But underneath they are raging with unhappy love, or vengeance, or some point of honor or ambition–all connected with their professional lives. They go to La Bohème or La Traviata and they remember some early affair that might have been squalid if you weren’t living it yourself; or they see Rigoletto and think how the chairman humiliated them at the last board meeting; or they see Macbeth and think how they would like to murder the chairman and get his job. Only they don’t think it; very deep down they feel it, and boil it, and suffer it in the primitive underworld of their souls. You wouldn’t get them to admit anything, not if you begged. Opera speaks to the heart as no other art does, because it is essentially simple.”
