Mr. Lunn feels sure that the true vocal cords are not involved in falsetto, that voice being produced by the false vocal cords.
Mantels says that in the falsetto voice the vocal cords do not produce pitch, that the quality and mechanism are both that of the flute, that the cords set the air in vibration and the different tones are made by alterations in the length of the tube.
Davidson Palmer says that the falsetto is the remnant of the boy’s voice which has deteriorated through lack of use, but which is the correct mechanism to be used throughout the tenor voice.
Mr. Chater argues along the same lines as Mr. Mantels except that he makes the instrument belong to the clarinet or oboe class. Others believe the vocal cords act as the lips do in playing a brass instrument.
But the action of the vocal cords is but the first part of the unscientific controversy. What takes place above the vocal cords is equally mystifying. The offices of the pharynx, the mouth, the nasal cavities, the entire structure of the head in fact, are rich in uncertainties.
Some think the cavities of the pharynx and head are involved acoustically and in some way enlarge, refine and purify the tone, but one famous man says the head has nothing whatever to do with it. Another gentleman of international reputation says the nose is the most important factor in singing. If your nasal cavities are right you can sing, otherwise you cannot.
And so this verbal rambling continues; so the search for mind in matter goes on, with a seriousness scarcely equalled in any other line of strife. There is nothing more certain to permanently bewilder a vocal student than to deluge him with pseudo-scientific twaddle about the voice. And this for the simple reason that he comes to learn to sing, not for a course in anatomy.
What is scientific voice production? Books without number have been written with the openly expressed intention to give a clear exposition of the subject, but the seeker for a scientific method soon finds himself in a maze of conflicting human opinions from which he cannot extricate himself.
We are told with much unction and warmth that science means to know. That it is a knowledge of principles or causes, ascertained truths or facts. A scientific voice teacher then must know something. What must he know? Books on scientific voice production usually begin with a picture of the larynx, each part of which is labeled with a Greek word sometimes longer than the thing itself. It then proceeds to tell the unction of each muscle and cartilage and the part it plays in tone production. Now if this is scientific, and if science is exact knowledge, and this exact knowledge is the basis of scientific voice teaching, then every one who has a perfect knowledge of these facts about the voice, must in the eternal and invariable nature of facts be a perfect voice teacher, and every one of these perfect voice teachers must teach in exactly the same way and produce exactly the same results. Does history support this argument? Quite the reverse.
There is a science of acoustics, and in this science one may learn all about tones, vibrating bodies, vibrating strings, vibrating cavities, simple, compound and complex vibrations. Will this knowledge make him a scientific voice teacher? When he has learned all of this he has not yet begun to prepare for voice teaching. There is no record of a great voice teacher having been trained in a physics laboratory.
