"The pianist before the public, or the player who hopes to master the
instrument in the future, never thinks of omitting the daily task of
scales and exercises; he knows that his chances for success would soon
be impaired, even ruined, if he should neglect this important and
necessary branch of study.
"It is exactly the same thing with the singer. She cannot afford to do
without scales and exercises. If she should, the public would soon find
it out. She must be in constant practice in order to produce her tones
with smoothness and purity; she must also think whether she is producing
them with ease. There should never be any strain, no evidence of effort.
Voice production must always seem to be the easiest thing in the world.
No audience likes to see painful effort in a singer's face or throat.
