Singing forward, then, does not mean pressing the whole of the breath or the tone forward, but only part of it; that is, in the middle register, finding a resonating focus in front, caused by the lowering of the front of the palate. This permits a free course only to that part of the breath which is used up by the whirling currents in the resonant throat form, and serves to propagate the outer waves, and carry them farther through space.
SECTION XIII
SINGING COVERED
We sing covered as soon as the soft palate is lowered toward the nose (that is, in the middle register), and the resonance and attack are transferred thither so that the breath can flow over the soft palate through the nose.
This special function of the palate, too, should be carefully prepared for in the tones that precede it, and mingled with them, in order not to be heard so markedly as it often is. In men's voices this is much more plainly audible than in women's; but both turn it to account equally on different tones. This often produces a new register that should not be produced. This belongs to the chapter on [registers].
The tone is concentrated on the front of the palate instead of being spread over all of it—but this must not be done too suddenly. [See illustrations on pages 127, 129, 131, 133.]
