A defective voice will always preclude an artist from achieving the complete development of his art, however intelligent he may be.... The voice is an instrument which the artist must learn to use with suppleness and sureness, as if it were a limb.
The artist's personality must be left in his dressing-room; his soul must be denuded of its own sensations and clothed with the base or noble qualities he is called upon to exhibit.... [he] must leave behind him the cares and vexations of life, throw aside his personality for several hours, and move in the dream of another life, forgetting everything.
