Breathing,
for the latter in its relations to vocalization depends much upon position. The breath is the motive power of the voice in speech or song, and the fundamental importance of managing it aright has been understood by every teacher of voice since the time of Porpora.
How for singing purposes breath shall be taken, how exhaled, how managed in short, is not yet entirely settled and presumably never will be, for people are not born wise, and some never acquire wisdom, of whom a few teach music. Browne and Behnke, in “Voice, Song, and Speech,” p. 138-142, describe the process of breathing as follows:
“There are three ways of carrying on the process of respiration, namely, midriff breathing, rib-breathing, and collar-bone breathing. These three ways are not wholly independent of one another. They overlap or partly extend into one another. Nevertheless, they are sufficiently distinct and it is a general and convenient practice to give to each a separate name, according to the means by which it is chiefly called into existence. The combined forms of midriff and of rib-breathing constitute the right way, and collar-bone breathing is totally wrong and vicious, and should not in a state of health be made under any circumstances. When enlarging our chests by the descent of the midriff, we inflate our lungs where they are largest and where consequently we can get the largest amount of air into them. When expanding our chests by raising the shoulders and collar-bones, we inflate the lungs where they are smallest and where, consequently, we get the smallest amount of air into them. The criterion of correct inspiration is an increase of size of the abdomen and the lower part of the chest. Whoever draws in the abdomen and raises the upper part of the chest breathes wrongly.”
In normal breathing the body at inspiration increases in girth at the waist, and the abdomen moves slightly outward as the viscera are forced downward by the descent of the diaphragm. The diaphragm is a large muscle which serves as a partition between the thorax or chest-cavity and the abdomen. When relaxed its middle portion is extended upward into the chest-cavity, presenting a concave surface to the abdomen. At inspiration it contracts, descending so as to assume very nearly a plane figure. At expiration the process is reversed, the diaphragm relaxes and the abdominal viscera, released from its pressure and forced by the abdominal muscles which contract as the diaphragm relaxes, moves upward and inward.
This kind of breathing in which the muscular contraction of the diaphragm calls in operation atmospheric pressure, supplies the body, when tranquil, with nearly or quite enough air. When for any reason a larger quantity of air is demanded, it may be secured by raising the ribs, thereby increasing the chest-cavity.
In singing, the breath must be managed so that the air passing through the larynx at expiration shall be set into vibration at the vocal bands. Expiration, then, which ordinarily occurs very quickly must be retarded by slowly relaxing the muscles which contract at inspiration. At the same time the throat must be open, and the muscles surrounding the resonance cavities relaxed to allow free movement of the sound-waves set up at the vocal bands. Any upward movement of the shoulders and chest at inspiration involving the contraction of many powerful muscles of back and neck will occasion a stiffening of the throat, which prevents free vibration of the vocal bands and seriously interferes with the resonance of tone.
The conclusion of the whole matter is, that in singing we should take breath exactly as in the ordinary quiet respiration, and avoid any lifting of the shoulders. This is at least enough to say to a class of children upon the subject.
The means adopted in education should be as simple and direct as possible. It will be found unnecessary to say very much about breathing in dealing with classes of children. In the first place, the moment the subject is broached and the direction “take a good breath” or a similar one given, each child will draw up the chest and shoulders prepared for a mighty effort; while, if nothing is said about it, position alone being attended to, the breathing will be all right. And again, while adult singers for various reasons, one of which may be the supposition that the more energy put forth the better the tone, often present themselves to the voice-teacher with a fine assortment of bad breathing-habits, children, on the contrary, are sent to school at so young an age that a little watchfulness on the part of the teacher only is necessary to avoid improper ways of taking breath and establish good habits. If young children, then, are not permitted to raise the shoulders, they will perforce breathe properly.
It seems inadvisable also to give any instruction regarding the emission of air from the lungs in singing. None but cultivated singers, after long practice and through a complete command of the muscles concerned, can vocalize all the air at the vocal bands. The absolute purity of tone which is thus secured is a result that may or may not be reached in any particular case. It depends upon the mental and physical organization of the pupil as well as upon the method of the teacher.
