How are you to get this, you ask. By study and long practice. As you plainly see, it involves a perfect command over the feelings; and "he that ruleth his own spirit is greater than he that taketh a city." Conquer yourself. All art, elocution included, is but a means of expression for man's thoughts and feelings; and, if you have no thought or feeling to express, art is useless to you.
Breathing.
Do not let your audience be reminded that you breathe at all. Take breath quietly through nostrils or mouth, or both. Form the habit of keeping the chest, while speaking, active, as recommended in all vocal exercises; and the breath will flow in unobstructed whenever needed. Breathe as nearly as possible as you would if you were not speaking, that is, do not interfere with right action of the lungs. The instant you feel a want of breath, take it: if you do not, you will injure your lungs; and what you say, feeling that want of breath, will lack power. The more breath you have, so that it does not feel uncomfortable and can be well controlled, the more power you will have: therefore practise breathing until you breathe rightly and easily.
Throat trouble.
If your general health is good, your throat will be well; and therefore pay attention to the general health of the whole body, and the throat will take care of itself. If, when you come before an audience, your throat and mouth are dry, use only clear, cold water, not ice-water: that is too cold. Avoid candy or throat-lozenges; for the use of either of these is worse than if you used nothing at all. If you have a cold or sore throat, you had better not use your voice; but, if you must use it, keep it clear by clear water. A healthy throat will not need even water: it will moisten itself after a little use, if at first it is dry.
Pausing.
Deliberate movement and frequent pausing are very expressive in some cases. Where it is applicable may be determined by what you have to express. Pausing in its appropriate place makes emphasis strong. | Punctuation.| Let the pause be regulated, however, by the feeling, and not all by the punctuation. Express according to your conception of the thought. Punctuation may be a guide to you in obtaining the right idea; but it is no guide to correct expression. Pausing, generally, comes naturally either before or after, or both before and after, the emphatic word or phrase.
Poetry.
Speak or read poetry with the same care and attention to phrasing that you would give to prose, and you will avoid all drawling, monotony, or sing-song. In order that the rhyme in poetry may be preserved, the pronunciation of a word may be changed from common usage, if, by so doing, you do not obscure the meaning; but never sacrifice the meaning for the sake of the rhyme. In good poetry, which includes blank verse, the metrical movement will show itself without any attempt on your part to make it prominent.
Stage fright.
