Not only in regard to "registers" but in regard to resonance, focus, articulation, and the offices and uses of the various vocal organs, similar antagonistic opinions exist. Out of this chaos must some time come a demonstrable system.
A generation ago the art of breathing was beginning to be more an object of study, but the true value of correct lateral abdominal breathing was by no means generally admitted or appreciated. It was still taught that the larynx (voice-box) should bob up and down like a jack-in-a-box with each change of pitch, and that "female breathing" must be performed with a pumping action of the chest and the elevation and depression of the collar bone.
Fortunately, teachers and singers recognized a good tone when they heard it, and many taught much better than they knew, so that the public did not have to wait for the development of accurate knowledge of the subject before hearing excellent singing and speaking. Yet many singers had their voices ruined in the training, and their success as vocalists made impossible; while others, a little less unfortunate, were still handicapped through life by the injury done by mistaken methods in early years. Jenny Lind's perfect vocal organs were quite disabled at twelve years of age by wrong methods, and they recovered only after a protracted season of rest. As a consequence her beautiful voice began to fail long before her splendid physique, and long before her years demanded. Singers taught in nature's way should be able to sing so long as strength lasts, and, like Adelaide Phillips, Carl Formes, and Sims Reeves, sing their sweetest songs in the declining years of life. Martel, at seventy years of age, had a full, rich voice. He focused all his tones alike, and employed deep abdominal breathing.
The whole matter of voice training has been clouded by controversy. The strident advocates of various systems, each of them "the only true method," have in their disputes overcast the subject with much that is irrelevant, thus obscuring its essential simplicity.
The "scientific" teachers, at one extreme, have paid too exclusive attention to the mechanics of the voice. The "empiricists" have gone to the other extreme in leaving out of account fundamental facts in acoustics, physiology, and psychology.
The truth is that no purely human function, especially one so subtle as singing, can be developed mechanically; nor, on the other hand, can the mere ipse dixit of any teacher satisfy the demands of the modern spirit.
PRINCIPLES ADVOCATED
The positions here advocated, because they seem both rational and simple, are:
1. That the singing and speaking tones are identical, produced by the same organs in the same way, and developed by the same training.
2. That breathing is, for the singer, only an amplification of the correct daily habit.
