As the voice is guided by the ear, the first requirement of a singer is a keen sense of hearing. For a keen ear to be of benefit, the student must learn to listen to his own voice. This is not altogether an easy matter. For one to learn to hear oneself justly and correctly requires considerable practice. The singer is placed at a natural disadvantage in listening to himself. This is due to two causes. In the first place, the direct muscular sensations of singing are so complex, and so distributed about the throat and face, that the singer's attention is apt to be divided between these and his auditory sensations. Second, the sound waves are conducted to the ear internally, by the vibration of the bones of the head, as well as externally, by the air waves. The internally conveyed vibrations are a rumbling rather than a true sound; the only true tone is the external sound, heard by the singer in the same way as by a listener. Yet the attention is more apt to be taken up with the internal rumbling than with the external tone. Every vocal student must be taught to listen to himself, to disregard the muscular sensations and the internal rumbling, and to pay attention only to the real tones of his voice.
Throat stiffness greatly increases the difficulty of listening to oneself. Both the muscular sensations and the internal rumbling are heightened by the increased muscular tension. A stiff-throated singer confounds the muscular with the auditory sensations; the feeling of muscular effort also makes him believe his tones to be much more powerful than they really are.
The Acquirement of Skill
Skill in the use of the voice is acquired solely by practice in singing. Only one rule is required for the conduct of vocal practice, that is, that the voice thrives on beautiful sounds. Musical taste must always guide the vocal student in practising. The voice cannot well do more than is demanded by the ear. If a student is unable to distinguish a correct intonation, his voice will not intone correctly. A student must hear and recognize his own faults or there is no possibility of his correcting them. He must be familiar with the characteristics of a perfect musical tone in order to demand this tone of his voice.
In the student's progress the ear always keeps slightly in advance of the voice. Both develop together, but the ear takes the lead. The voice needs practice to enable it to meet the demands of the ear. As this practice goes on day by day the ear in the meantime becomes keener and still more exacting in its demands on the voice.
To train a voice is in reality a very simple matter. Nothing is required of the student but straightforward singing. Provided the student's daily practice of singing be guided by a naturally keen ear and a sound musical taste, the voice will steadily progress. Little need be said here about the technical demands made on the voice in modern music. The standards of vocal technique are well known to all vocal teachers, and indeed to musicians generally. Further, the scope of this work is limited to the basic principle of vocal technique,—correct tone-production.
For starting the voice properly on the road to the perfect action, intelligently guided practice alone is needed. This practice must be carried on under the direction of a competent teacher. But the teacher cannot pay attention solely to the technical training of the student's voice. As has been seen, the training of the voice is impossible without the cultivation of the sense of hearing; and this is dependent in great measure on the general musical education of the student. The teacher must therefore direct the student's musical education as the basic principle of Voice Culture.
The Avoidance of Throat Stiffness
A great advance will be brought about in the profession of Voice Culture when vocal teachers become thoroughly familiar with the subject of throat stiffness. This is the only troublesome feature of the training of voices. Teachers must be always on the alert to note every indication of throat stiffness. The correction of faults of production has always been recognized as one of the most important elements of vocal training. Faults of production are of two kinds, natural and acquired. Natural faults are exhibited in some degree by every vocal student. These are due solely to the lack of facility in the use of the voice and to the beginner's want of experience in hearing his own voice. Acquired faults develop only as the result of unnatural throat tension. The most common cause of acquired faults of tone-production was seen in the attempt consciously to direct the mechanical operations of the voice.
Equipped with a thorough understanding of the subject of throat stiffness, the teacher is in no danger of permitting his pupils to contract faulty habits of tone-production. Here the great value of the empirical knowledge of the voice is seen. The slightest trace of incipient throat stiffness must be immediately detected by the teacher in the sound of the pupil's tones. To correct the faulty tendency in the beginning is comparatively simple. By listening closely to every tone sung by his pupils in the course of instruction, noting both the musical character of the tones and the sympathetic sensations of throat action, the master will never be in doubt whether a tendency to throat stiffness is shown. In locating the natural faults of production the teacher will also find his empirical knowledge of the voice a most valuable possession.
