This curve should become a fixed mental object during all vocal practice, whether in speaking or in singing. Holding this object must become a habit so firmly established that the mind will ultimately act above consciousness in forming it. The vocal organs always react upon ideals held in the mind. Thus, if a flat object is held in the mind while using the voice, the tone tends to flatness; if a round one, it tends to roundness; if a narrow form, it tends to narrowness; if a contracting figure, it tends to contraction; if a free, elastic, expansive one, it tends to freedom, elasticity, and expansiveness. The figure of an expanding globe gives the voice the qualities last described. This figure, moving in the form of a curve, unites to the above qualities that of beauty, for the curve always awakens in the imagination the sense of the beautiful. Tone is vocalized breath. It is observable that the higher order of animals usually begin their tones in the form of the nares resonance. When the cow lows for her young the tone is resounded in the nares before the mouth opens. The same thing is to be noticed in the mother horse calling to her young. She begins the tone with the nares resonance, and as the impulse increases she opens her mouth to let forth the whinnie so full of feeling. No animal excels the house cat in the correct use of the voice. She begins her tone as a nares resonance, and when her mouth opens, the tone which is moving in the right direction indicates that her vital energies are fully aroused. She acts upon the same principle that a man does in aiming a gun. He aims before he fires. Nature aims the tone before she gives the explosion. The mightiest of all voices is that of the lion. He distinctly guides his tone with the nares resonance. If he did not so direct it, the blast of tone which shakes the very earth would rend his throat. Many people injure their throats by letting on a power of voice which is not properly guided. The only reason a person’s throat ever suffers from continued use of the voice is because the tone is not properly directed. Some public speakers after using their voices for an hour, or even half an hour, feel an irritation in their throats, but if their tones were properly directed, they could use their voices without injury as long as their general strength would permit. The moment the current of tone is turned from its proper direction, the voice is being injured. All the muscles of respiration work in a harmonious manner with each other when the tone is properly directed; they work improperly together in a way to produce friction when the tone is not centered. _TONE QUALITY._
