These, then, are the first exercises in the second step in vocal training. This step is called Freeing the Tone.
First.—Yawn, noting the sensation.
Second.—Just before the throat breaks into the yawn, stop, and, instead of carrying out the yawn, speak. Repeat this fifty times a day, or ten times, as often as you will. Only, keep at it. Take always a single full-voweled monosyllable; one, or four, or no, or love, or loop, or dove, etc.
We cannot, in a printed consideration, touch more in detail upon individual cases, but must confine ourselves to these simple exercises, which will, in general, be swiftly and effectively remedial.
But we must not stop with the throat, which is but part of the channel involved in the emission of breath as speech. There is the tense jaw to be reckoned with—the jaw set by nervous tension, the jaw which refuses to yield itself to the moulding of the tone into the beautiful open vowel and the clean-cut consonant which make our words so interesting to utter. It is the set jaw which, forcing the tone to squeeze itself out, causes it to sound thin and hard. Again, it is surrender and not effort I want. Just as I should try to secure the relaxation of your arm or hand by asking you to surrender it to me, drop it a dead weight at your side for me to lift as I choose, so now I ask you to surrender your lower jaw to yourself. Let it go.
Drop your head forward, resting your chin on your chest. Then raise your head, but not your chin. Let your mouth fall open. Assume for the moment that mark of the feeble-minded, the idiotic, the dropped-open mouth, just long enough to note the sensation. Place your fingers on either side of your head where the jaws conjoin, and open your mouth quickly and with intention. Note the action under your finger-tips. Now let the mouth fall open, by simply surrendering the lower jaw, and note this time the lack of action under your fingers, at the juncture of the jaws. It is this passive surrender which we must learn to make, if we find, on investigation, that we are speaking through a half-open mouth held fast by a set jaw. The set jaw resists and distorts the mould, and the beauty of the form of the word which flows from the mould is lost; the relaxed jaw yields to the moulding of the perfectly modeled word.
In practising this relaxation there is very little danger of going too far, since the set jaw is the indication of a tense habit of thought, of a high-strung temperament, and this habit of thought will never become, through the practise of an outward mechanical exercise, the slack habit of thought which is evidenced by the loose dropping of words from a too relaxed jaw—a habit which must be met by quite the opposite method of treatment. There are many exercises involved in vocal training which must be directed very carefully for a time before the student can be trusted to practise them alone; so I am confining myself in this, as in every step we take together, to the simple, fundamental, and at the same time perfectly safe ones.
To review those for relaxation of the lower jaw:
First.—Drop the head until the chin rests upon the breast. Raise the head, but not the lower jaw.
Second.—With eyes devoid of intelligence and the mouth dropped open, shake the head until you feel the weight of the lower jaw—until the lower jaw seems to hang loosely from the upper jaw and to be shaken by it, as your hand, when you shake it from the wrist, seems to be commanded by the arm, and to have no volition of its own.
