chapter is, of course, written especially for the instrumentalist, and our advice to him is not merely to read books about singing, but to study singing itself, whether he is interested in cultivating his own voice for solo purposes or not. It might be remarked in this connection that aside from the considerations that we have been naming, the conductor who can sing a phrase to his orchestra or chorus and thus show by imitation exactly what shading, et cetera, he wishes, has an enormous advantage over him who can only convey his ideas by means of words.
PROPER BREATHINGProbably the first thing about singing to learned by the student of conducting is that good voice production depends upon using the full capacity of the lungs instead of merely the upper portion. Hence the necessity of holding the body easily erect as a matter of habit, with chest up, and with the diaphragm alternately pushing the viscera away in order to enable the lungs to expand downward, and then allowing the parts to come back into place again, as the air is in turn expelled from the lungs. By practising deep breathing in this way the actual capacity of the lungs may be considerably increased, and breathing exercises have therefore always formed part of the routine imposed upon the vocal student. A deep breath involves, then, a pushing down of the diaphragm and a pushing out of the lower ribs, and not merely an expansion of the upper part of the chest. The singer must form the habit of breathing in this way at all times. To test breathing, the singer may place the hands about the waist on the sides of the thorax (fingers toward the front, thumbs toward the back) and see whether there is good side expansion of the ribs in inhaling, and whether in taking breath the abdomen swells out, receding as the air is expelled. We have always felt that a few minutes spent at each chorus rehearsal in
