FORCE.
Force is the degree of loudness or softness we may give to the voice. You should be able to speak gently without feebleness or weakness of voice, and so as to be distinctly heard in a large hall, and also to make the fullest and loudest voice without showing any effort to do so.
1. Gentle Force.—Chant and read sentences, as under "Pitch," with the gentlest force you can, and yet make it so as to seem to be clear and distinct. Do this on every pitch you can, high or low.
2. Moderate Force.—Read and chant as above on the middle and higher tones, with about the force of earnest conversation.
3. Loud Force.—Read and chant as above, using only the middle and lower tones of the voice, making the loudest tones you can, without straining the throat. Force of voice depends on the management of the muscles below the lungs; and you should have perfect freedom from all effort on the part of lungs, throat, or mouth, on any pitch, high, middle, or low. If any effort is perceptible to you, it will be a feeling of strength and power at the waist; and experience and practice must teach you how much or how little effort to make at that point. The loudest force, and at the same time the purest quality, is secured when it seems to make itself without the slightest feeling of effort on your part.
