We have here the only law of vocal management:
– The vocal organs adjust themselves instinctively and automatically to produce the tones demanded by the mental ear.
To apply this law to the training of the voice, it is necessary that the vocal organs be not interfered with in their operations. When there is any interference the tone cannot be correctly produced and the voice cannot be properly trained. Throat stiffness, an excessive tension of the muscles of the vocal organs, is the influence which most frequently brings about this interference.
A simple illustration will serve to show how muscular stiffness may interfere with our voluntary actions. Take a pencil and a sheet of paper and start to write a few lines. Grip the pencil as hard as you can, and press with all the force of your arm on the paper. You will find that when you write with your hand and arm in this stiffened condition, the writing is cramped and ugly, and your hand grows tired.
When the vocal organs are in a condition of strain, similar to that illustrated by writing with the hand and arm cramped, it is impossible for the voice to respond perfectly to the demands of the mental ear. This does not mean that the instinctive connection between the voice and the mental ear is broken. On the contrary the voice makes the best response that it can. But in their stiffened condition the response of the vocal organs is not perfect, as it would be if there were no interference. Throat stiffness does not prevent the use of the voice; it only impedes the free operation of the vocal organs. The greater the degree of throat stiffness, the more the voice is hampered, and the worse the tone production becomes.
Even when the natural untrained voice is free from throat stiffness, it still requires cultivation before its tone production is perfect. In the course of correct training a change of some kind takes place in the operations of the voice. Several theories are offered as to the nature of this change. But the vocal student is not concerned with this matter. Even if the operations of correct tone production were thoroughly understood, that would not help the student in acquiring perfect control of the voice. For the voice needs no help of any kind, no directions from the OUTSIDE as to how its adjustments are to be made.
Voice training is not the acquiring of the ability consciously to direct or manipulate the vocal organs. Provided the mind has the right conception of artistic tone, and there is no interference from throat stiffness, correct tone production is acquired by the practice of singing under the sole guidance of the ear.
