Henry Edward Krehbiel,
How to Listen to Music, 7th ed
“ The modern conductor is, in a sense not dreamed of a century ago, a mediator between the composer and the audience. He is a virtuoso who plays upon men instead of a key-board, upon a hundred instruments instead of one. Music differs from her sister arts in many respects, but in none more than in her dependence on the intermediary who stands between her and the people for whose sake she exists. It is this intermediary who wakens her into life. ”
