outbreathing. In general it may be said that the singer should breathe with the least possible disadjustment, so that only the least possible readjustment will be needed and the effort of breathing be minimized. Nature herself is economical, and the singer should economize the resources of breath. To breathe easily and without a waste of energy is essential to the best art, and gives a feeling to the listener that the singer, whose work he has enjoyed, has even more in reserve than he has given out. That sense of reserve force is one of the greatest triumphs of art. It is largely the result of effortless breathing, in which it is not necessary or even desirable that the singer always should strive to fill the lungs to the utmost, since that induces an obvious effort which diminishes the listener's enjoyment. Moreover, effort goes against the economy of nature. By keeping this in mind and by the use of correct methods, the singer will be able, in time, to gauge the amount of breath he requires for the tone he is about to produce or the phrase he is about to deliver, and the natural demand of the lungs will become his guide.

It is essential to correct breathing that the organs of the tract through which the breath passes in and out should at least be known. They include the

mouth, nose, larynx, trachea (or windpipe), the bronchial tubes and the lungs. A narrow slit in the larynx, called the glottis, and where the vocal cords are located, leads into the windpipe, a pliable tube composed of a series of rings of gristly or cartilaginous substance. The bronchial tubes are tree-like branches of the windpipe, and extend to the lungs, which are extremely elastic and, upon being filled with air, become inflated and expand somewhat like a balloon. It is necessary that in taking in breath and expelling it, this natural apparatus should be under the singer's control and that no undue force should be exerted upon the whole or upon any part of it, since this would result in its physical impairment and a corresponding impairment in production and quality of voice. It cannot be emphasized too often that the scientific method of voice-production based on the study of the physiology of the vocal tract is not a fad; as is proved by the fact that every violation of physical law affecting the vocal tract results in injury to it and in the same proportion affects the efficiency of the voice.

Before considering various methods of breathing it should be said that, irrespective of these, air should, whenever it is possible to do so, be taken into

the lungs through the nostrils and not through the mouth. True, there are times in singing when breath has to be taken so rapidly that mouth-breathing is a necessity, as otherwise the inspiration would not be rapid enough. But to inspire through the nostrils, whenever feasible, is a law not alone for the singer, but a fundamental law of health. In the passage from the mouth to the lungs there is no provision for sifting the air, for freeing it from foreign matter, or for warming it if it is too cold; whereas the nostrils appear to have been designed for this very purpose. Their narrow and winding channels are covered with bristly hairs which filter or sift and arrest the dust and other impurities in the air; and in the channels of the nostrils and back of them the air is warmed or sufficiently tempered before it reaches the lungs. Moreover it can be felt that the lungs fill more readily when air is taken in through the nostrils than when inspiration takes place through the mouth. That breath should be taken in through the nostrils is, like all rules in the correct physiology of voice-production, deduced from incontrovertible physical facts. It is, moreover, preventive of many affections of the lungs, bronchial tubes and throat.

Three methods of breathing usually are recognized in books on singing—but there should be only one. For only one method is correct and that really is a combination of the three. These three are called, respectively, clavicular, abdominal or diaphragmatic, and costal; clavicular, because it employs a forced movement of the clavicle or collar-bone accompanied by a perceptible raising of the shoulder-blades; abdominal or diaphragmatic, because breathing by this method involves an effort of the diaphragm and of the abdominal muscles; and costal, which consists of an elastic expansion and gentle contraction of the ribs, the term "costal" signifying "pertaining to the ribs."

Let me say right here, subject to further explanation, that neither of these methods by itself is complete for voice-production and that the correct method of breathing consists of a combination of the three, with the costal, or rib-expansion method, predominating. For of the three methods mentioned the expansion of the ribs creates the largest chest-cavity, within which the lungs will have room to become inflated, so that more air can be drawn into them by this method than by either of the others. But a still larger cavity can be created and a still greater intake of air into the lungs be provided

for, if, simultaneously as the ribs are expanded, the diaphragm, the large muscle separating the cavity of the chest from that of the abdomen, is allowed to descend and the clavicle is slightly raised, the final act in this correct method of breathing being a slight drawing in of the lower wall of the abdomen. Ignoring the slight raising of the clavicle, this method may be called the mixed costal and diaphragmatic, for it consists mainly in expanding the ribs and in allowing the dome-shaped top of the diaphragm to descend toward the abdomen. It calls into play all the muscles that control respiration and their coöperative nerves, provides the largest possible space for the expansion of the lungs, and is complete in its results, whereas each of the three methods of which it is a combination is only partial and therefore incomplete in result.

In the method of breathing called clavicular, the hoisting of the shoulder-blades is an upward perpendicular effort which is both ugly to look at and disagreeable in its results. For in art no effort, as such, should be perceptible. Moreover, as in all errors of method in voice-teaching, there is a precise physiological reason why clavicular breathing is incorrect. Correct breathing results, with each
