VOCAL FLEXIBILITY
In the earliest exercises here given the tone will be, for the best and most immediate effect, kept running on somewhat in a straight line, so to speak; will have a certain sameness of sound; will be perhaps somewhat monotonous, because kept pretty much in one key, or in one average degree of pitch. It will perhaps be necessary to make the utterance for the time somewhat artificial. The voice is in the artificial stage, as is the work of an oarsman, for example, in learning the parts of the stroke, or that of a golfer in learning the "swing," although in the case of some students, when the vocal conditions are good and the tone is well balanced, very little of the artificial process is necessary. In that case the voice simply needs, in its present general form, to be developed.
The next step in the training is to try a more varied use of the voice, without a loss of what has been acquired as to formation of tone. The student is to make himself able to slide the voice up and down in pitch, by what is called inflection, to raise or lower the pitch by varied intervals, momentarily to enlarge or diminish the tone, in expressive ways; in short, to adapt the improved tone, the more effective method of voice control, to more varied speech. In the early practice for getting tone variation, the student must guard most carefully against "forcing." Additional difficulties arise when we have vocal changes, and moderate effort, in the degree of the change, is best. In running the tone up, one should let the voice take its own way. The tone should not be pushed or held by any slightest effort at the throat. The control should, as has been said, be far below the throat. In running an inflection from low to high, the tone may be allowed, especially in the earlier practice, to thin out at the top. And always when the pitch is high the tone should be smaller, as it is on a musical instrument, though it should have a consistent depth and dignity from its proper degree of connection with the chest. This consistent character in the upper voice is attained by giving the tone a bit of pomp or nobleness of quality. In taking a low pitch there is, among novices, always a tendency to bear down on the tone in order to gain strength or to give weight to utterance. The voice is thus crowded into, or on, the throat. The voice should never be pushed down or pressed back in the low pitch. This practice leads to raggedness of tone, and finally to virtual loss of the lower voice. The voice should fall of itself with only that degree of force which is legitimately given by the breath tension, produced easily, though firmly, by the breathing muscles. Breadth will be given to the tone by some degree of expansion at the back of the mouth, or in the pharynx. As soon as can be, the speech should be brought down to the utmost of simplicity and naturalness, so that the thought of literature can be expressed with reality and truth; can be made to sound exactly as if it came as an unstudied, spontaneous expression of the student's own mind, and yet so it can be heard, so it will be adequate, so it will be pleasing in sound. The improved tone is to become the student's inevitable, everyday voice.
