It always makes me sad when I think of how I saw Wagner wasting his vitality, not only by singing their parts to some of his artists, but acting out the smallest details, and of how few they were who were responsive to his wishes.

Of course, experience strengthens one later.

Musical practice is too young an art in America to warrant a search for men with a conductor's gift.

I learned, too, how it was possible with the help of the picture and action to transform an apparently insignificant violin passage into an incident, and to lift a simple horn call into a thing of stupendous significance by means of scenic emphasis.
