If I were to teach a young girl right at this moment I would simply ask her to take a deep breath and note the expansion at the waist just above the diaphragm. Then I would ask her to say as many words as possible upon that breath, at the same time having the muscles adjacent to the diaphragm to support the breath; that is, to sustain it and not collapse or try to push it up. The trick is to get the most tone, not with the most breath but with the least breath, and especially the very least possible strain at the throat, which must be kept in a floating, gossamer-like condition all the time. I see girls, who have been to expensive teachers, doing all sorts of wonderful calisthenics with the diaphragm, things that God certainly did not intend us to do in learning to speak and to sing.
Any attempt to draw in the front walls of the abdomen or the intercostal muscles during singing must put a kind of pneumatic pressure upon the breath stream, which is sure to constrict the throat. Therefore, in my own singing, I note the opposite effect. That is, there is rather a sensation of expansion instead of contraction during the process of expiration. This soon becomes very comfortable, relieves the throat of strain, relieves the tones of breathiness or all idea of forcing. There is none of the ugly heaving of the chest or shoulders; the body is in repose, and the singer has a firm grip upon the tone in the right way. The muscles of the front wall of the abdomen and the muscles between the lower ribs become very strong and equal to any strain, while the throat is free.
In the emission of the actual tone itself I would advise the sensation of inhaling at first. The beginner should blow out the tone. Usually instead of having a lovely floating character, with the impression of control, the tone starts with being forced, and it always remains so. The singer oversings and has nothing in reserve. When I am singing I feel as though the farther away from the throat, the deeper down I can control the breath stream, the better and freer the tone becomes. Furthermore, I can sing the long, difficult Wagnerian rôles, with their tremendous demands upon the vocal organs, without the least sensation of fatigue. Some singers, after such performances, are "all in." No wonder they lose their voices when they should be in their prime.
For me the most difficult vowel is "ah." The throat then is most open and the breath stream most difficult to control properly. Therefore I make it a habit to begin my practice with "oo, oh, ah, ay, ee" in succession. I never start with sustained tones. This would give my throat time to stiffen. I employ quick, soft scales, always remembering the basic principle of breath control I have mentioned, and always as though inhaling. This is an example of what I mean. To avoid shrillness on the upper tone I take the highest note with oo and descend with oo.
The same thought applied to an arpeggio would be:
These I take within comfortable limits of my voice, always remembering that the least strain is a backward step. These exercises are taken through all possible keys. There can never be too much practice of a scale or arpeggio exercise. Many singers, I know, who wonder why they do not succeed, cannot do a good scale, the very first thing they should be able to do. Every one should be like perfect pearls on a thread.
America's Fatal Ambition
One of the great troubles in America is the irrepressible ambition of both teachers and pupils. Europe is also not untinged with this. Teachers want to show results. Some teachers, I am told, start in with songs at the first or second lesson, with the sad knowledge that if they do not do this they may lose the pupil to some teacher who will peddle out songs. After four or five months I was given an operatic aria; and, of course, I sang it. A year of scales, exercises and solfeggios would have been far more time-saving. The pupils have too much to say about their education in this way. The teacher should be competent and then decide all such questions. American girls do not want this. They expect to step from vocal ignorance to a repertoire over night. When you study voice, you should study not for two years, but realize you will never stop studying, if you wish to keep your voice. Like any others, without exercise, the singing muscles grow weak and inefficient. There are so many, many things to learn.
