The singer's endeavors, consequently, must be directed to keeping the breath as long as possible sounding and vibrating not only forward but back in the mouth, since the resonance of the tone is spread upon and above the entire palate, extends from the front teeth to the wall of the throat. He must concern himself with preparing for the vibrations, pliantly and with mobility, a powerful, elastic, almost floating envelope, which must be filled entirely, with the help of a continuous vocal mixture,—a mixture of which the components are indistinguishable.

SECTION IV

THE SINGER'S PHYSIOLOGICAL STUDIES

Science has explained all the processes of the vocal organs in their chief functions, and many methods of singing have been based upon physiology, physics, and phonetics. To a certain extent scientific explanations are absolutely necessary for the singer—as long as they are confined to the sensations in singing, foster understanding of the phenomenon, and summon up an intelligible picture. This is what uninterpreted sensations in singing cannot do; of which fact the clearest demonstration is given by the expressions, "bright," "dark," "nasal," "singing forward," etc., that I began by mentioning and that are almost always falsely understood. They are quite meaningless without the practical teachings of the sensations of such singers as have directed their attention to them with a knowledge of the end in view, and are competent to correlate them with the facts of science.

The singer is usually worried by the word "physiology"; but only because he does not clearly understand the limits of its teachings. The singer need, will, and must, know a little of it. We learn so much that is useless in this life, why not learn that which is of the utmost service to us? What, in brief, does it mean? Perfect consciousness in moving the vocal organs, and through the aid of the ear, in placing them at will in certain relations with each other; the fact that the soft palate can be drawn up against the hard palate; that the tongue is able to take many different positions, and that the larynx, by the assistance of the vocal sound oo, takes a low position, and by that of the vowel ā a high one; that all muscles contract in activity and in normal inactivity are relaxed; that we must strengthen them by continued vocal gymnastics so that they may be able to sustain long-continued exertion; and must keep them elastic and use them so. It includes also the well-controlled activity of diaphragm, chest, neck, and face muscles. This is all that physiology means for the vocal organs. Since these things all operate together, one without the others can accomplish nothing; if the least is lacking, singing is quite impossible, or is entirely bad.

Physiology is concerned also with muscles, nerves, sinews, ligaments, and cartilage, all of which are used in singing, but all of which we cannot feel. We cannot even feel the vocal cords. Certainly much depends for the singer upon their proper condition; and whether as voice producers or breath regulators, we all have good reason always to spare them as much as possible, and never to overburden them.
