In numerous instances the resistance in the vocal cords is so great that it is impossible to sing softly, or with half voice. It requires so much breath pressure to start the vibration, that is, to overcome the resistance, that when it does start it is with full voice. In a majority of male voices the upper tone must be taken either with full chest voice or with falsetto. There is no mezza voce. This condition is abnormal and is responsible for the “red in the face” brand of voice production so often heard.
Of this we may be sure, that no one can sing a good full tone unless he can sing a good mezza voce. When the mechanism is sufficiently free from resistance that a good pianissimo can be sung then the conditions are right to begin to build toward a forte.
Further, when the mechanism is entirely free from resistance there is no conscious effort required to produce tone. The singer has the feeling of letting himself sing rather than of making himself sing.
The engineer of a great pumping station once told me that his mammoth Corliss engine was so perfectly balanced that he could run it with ten pounds of steam. When the voice is free, and resting on the breath as it were, it seems to sing itself.
An illustration of the opposite condition, of extreme resistance was once told me by the president of a great street railway system that was operated by a cable. He said it required eighty-five per cent of the power generated to start the machinery, that is, to overcome the resistance, leaving but fifteen per cent for operating cars. It is not at all uncommon to hear singers who are so filled with resistance that it requires all of their available energy to make the vocal instrument produce tone. Such singers soon find themselves exhausted and the voice tired and husky. It is this type of voice production rather than climatic conditions, that causes so much chronic laryngitis among singers. I have seen the truth of this statement verified in the complete and permanent disappearance of many cases of laryngitis through learning to produce the voice correctly.
The second step in securing right conditions is the proper management of the breath.
BREATH CONTROL
An extremist always lacks the sense of proportion. He allows a single idea to fill his mental horizon. He is fanciful, and when an idea comes to him he turns his high power imagination upon it, and it immediately becomes overwhelming in magnitude and importance. Thereafter all things in his universe revolve around it.
The field of voice teaching is well stocked with extremists. Everything involved in voice production and many things that are not, have been taken up one at a time and made the basis of a method.
One builds his reputation on a peculiar way of getting the tone into the frontal sinuses by way of the infundibulum canal, and makes all other things secondary.
