Throughout the entire vocal profession, among singers, teachers, and students alike, there is a general feeling of the insufficiency of present knowledge of the voice. The problem of the correct management of the vocal organs has not been finally and definitely solved. Voice Culture has not been reduced to an exact science. Vocal teachers are not in possession of an infallible method of training voices. Students of singing find great difficulty in learning how to use their voices. Voice Culture is generally recognized as entitled to a position among the exact sciences; but something remains to be done before it can assume that position.
