The soap OPERA was so long ago - the thing about soap operas, and there's SOMETHING to be said for doing it, but you do a script a day. I don't want to say it's a TRAINING ground; it really isn't, but what it does teach you is discipline.
What is the source of power of MUSICIANS who are financially browbeaten, most of whom WORK for minimum wage or LESS? Musicians who cannot even AFFORD to buy tickets to operas or concerts in which they themselves perform?
Operas elucidate, in a WAYSOMETIMES absent in other theatrical productions, the very human fact that in every hero, there is a THREAD of duplicity. In every villain, there is another SIDE to consider: We don't have to LIKE him or her, but we are compelled to think about motivation.
