The Psychology of Singing Part 8

The boy begins by having before him a copy of the letters he is to write. Under the guidance of the eye the hand traces these letters. At each instant the eye points out to the hand the direction in which to move. As the hand occasionally wanders from the prescribed direction the eye immediately notes the deviation and bids the hand to correct it. The hand responds to the demands of the eye, immediately, without thought on the boy's part of nerve impulse or of muscular contraction. By repeated efforts the boy improves upon his first clumsy attempts; with each repet.i.tion he approaches nearer to the model.

In the course of this progress the muscular sense gradually comes to the a.s.sistance of the eye as a sort of supplementary guidance. But at no time is the eye relieved of the responsibility of guiding the hand in writing. To sum this up, the movements of the hand in writing are guided, so far as the consciousness is aware, directly by the sense of sight.

We have here the law of voluntary muscular guidance. In all voluntary movements the muscles are guided in their contractions, through some instinctive process, by the sense or senses which observe the movements themselves, and more especially, the results of the movements. In most actions the two senses concerned are sight and muscular sense. The more an action becomes habitual the more it tends to be performed under the guidance of muscular sense, and to be free from the necessity of the guidance of the eye. But muscular sense does not usually rise so high into consciousness as sight, in the guidance of muscular activities.

Many oft-repeated movements, especially those of walking, become thoroughly habitual and even automatic; that is, the muscular contractions are performed as purely reflex actions, without conscious guidance of any kind. But even in walking, the necessity may at any instant arise for conscious guidance. In such a case the sense of sight immediately comes into service; from reflex the movements become voluntary, and consciously guided. In the case of most complex actions the sense of sight furnishes the most important guidance.

If the muscular operations of singing are subject to the general laws of psychological control, the guidance of the vocal organs must be furnished by the sense which observes the results of the movements involved. This is the sense of hearing. Just as in writing the hand is guided by the eye, so in singing the voice is guided by the ear. There can be no other means of guiding the voice. Muscular sense may under certain conditions supplement the sense of hearing, but under no circ.u.mstances can muscular sense a.s.sume full command. The net result of the application of psychological principles to the problem of tone-production is simply this, that the voice is guided directly by the ear.

It is thus seen that the idea of mechanical vocal management is utterly erroneous. On pus.h.i.+ng the a.n.a.lysis still further the fallacy of this idea is found to be even more glaring.

Is a knowledge of anatomy of any a.s.sistance in the acquirement of skill in performing complex muscular actions? Not in the least. An understanding of muscular processes does not contribute in any way to skilful execution. The anatomist does not play billiards or row a boat one whit the better for all his knowledge of the muscular structure of the body.

Even if the precise workings of the vocal mechanism could be determined, the science of Voice Culture would not benefit thereby. Knowing how the muscles should act does not help us to make them act properly. It is utterly idle to tell the vocal student that as the pitch of the voice rises the arytenoid cartilages rotate, bringing their forward surfaces together, and so shortening the effective length of the vocal cords.

Whatever the vocal cords are required to do is performed through an instinctive obedience to the demands of the mental ear.

And finally, a precise a.n.a.lysis of muscular contractions is impossible, even in the case of comparatively simple actions. When, for example, the hand describes a circle in the air, a number of muscles are involved. True, it is known what these muscles are, and what effect the combined contractions of any group would have on the position of the hand. The direction of the hand's motion at any instant is determined by the resultant of all the forces exerted on this member. But as this direction constantly changes, so must the relative degrees of strength exerted by the muscles also constantly change. At no two successive instants are the muscular adjustments the same. This simple action, performed without thought or knowledge of the muscular processes, presents features too complex to be a.n.a.lyzed on the basis of mechanical law and anatomic structure.

A complete a.n.a.lysis of the muscular operations of tone-production is absolutely impossible. The adjustments of the laryngeal muscles involve probably the most minute variations in degree of contraction performed in the whole voluntary muscular system. What we do know of the mechanical operations of the voice is exceedingly interesting, and a further knowledge of the subject is greatly to be desired. But we can never hope to clear up all the mystery of the vocal action.

This statement must not be construed to mean that the study of the vocal mechanism has been devoid of valuable results. On the contrary, the present understanding of the mechanical operations of the voice will be found of very great value in erecting a true science of Voice Culture.

The only weakness of the present results of vocal investigation is due to the fact that this investigation has always been carried on under the influence of the idea of mechanical vocal management. This influence has led all theoretical students of the subject to attempt to apply their knowledge in formulating rules for direct mechanical guidance of the voice. That these rules are valueless is due solely to the fundamental error involved in the mechanical idea.

Voice Culture must be turned from the idea of mechanical vocal management. The old Italian masters were right in that they relied, even though empirically, on the imitative faculty. Modern teachers may do better, for in the light of present knowledge reliance on the faculty of vocal imitation can be shown to be in strict accord with sound scientific principles.

Part III

THE BASIS OF A REAL SCIENCE OF VOICE

CHAPTER I

THE MEANS OF EMPIRICAL OBSERVATION OF THE VOICE

To all knowledge obtained through the observation of facts and phenomena, the term empirical is properly applied. Empirical knowledge must be the basis of every science. To be available in forming a science, empirical knowledge of a subject must be so carefully gathered that all probability of error is eliminated; the observations must be so exhaustive as to embrace every possible source of information. From the knowledge thus obtained a set of verified general rules must be worked out with which all the observed facts and phenomena are shown to be in accord. Then a science has been erected. There is no possibility of conflict between empirical and scientific knowledge. The discovery of a single fact, at variance with the supposed general laws bearing on any subject, is sufficient to overthrow the entire structure which had been accepted as a science.

In the accepted Vocal Science the terms empirical and scientific are used in a sense entirely different from that which properly attaches to these words. Present knowledge of the operations of the voice is called scientific, solely because it is derived from the sciences of anatomy, acoustics, and mechanics. The term "empirical knowledge of the voice" is used as a name for knowledge of the subject drawn from any source other than these sciences. Yet so far as the modern vocal world seems to be aware, it possesses no knowledge of the voice other than that commonly called scientific. It is supposed that the old Italian masters had some "empirical understanding of the voice." But, if this was the case, their empirical knowledge has apparently been utterly lost.

Thus far in the present work, the usage of the terms empirical and scientific, accepted by vocal theorists generally, has been adopted. A distinction has been drawn between knowledge of the voice obtained through the study of the vocal mechanism and that obtained through observation of any other kind. The purpose will best be served by continuing this same usage.

It must be apparent to the reader, from the a.n.a.lysis of modern methods, that no real Science of Voice has thus far been erected. This is due to the fact that the general principles of scientific investigation have not been applied to the study of the voice. Under the influence of the idea of mechanical vocal management the attention of all investigators has been turned exclusively to the mechanical features of tone-production. Meanwhile the empirical knowledge of the old masters seems to have been forgotten. As a matter of fact, as will now be seen, this empirical knowledge has never been lost. Every modern teacher of singing shares the empirical knowledge which formed the sole material of the old method. But this knowledge is not applied effectually in modern instruction for two reasons. First, modern teachers do not realize the importance of this knowledge; indeed, they are practically unaware of this valuable possession. Although in fact the basis of nearly all modern instruction in singing, empirical knowledge is always unconsciously used. Second, empirical knowledge is always applied in the prevailing mechanical spirit. The attempt is always made to translate the sub-conscious empirical understanding of the voice into rules for direct mechanical management. Under the influence of the mechanical idea the modern teacher's most valuable possession, empirical knowledge of the voice, becomes utterly unserviceable.

Thus far, the whole result of this work has been destructive. The accepted Vocal Science has been shown to be erroneous in its conception and unsound in its conclusions. The work cannot halt here. Vocal Science must be reconstructed. This can be done only by following the general plan of all scientific investigation, beginning with the observation of all ascertainable facts bearing on the voice.

How can any facts be observed about the voice other than by the study of the vocal mechanism? An answer to this question is at once suggested so soon as scientific principles are applied to the subject. Strictly speaking, the voice is a set of sounds, produced by the action of the vocal organs. The scientific method of inquiry is therefore to begin by observing these sounds. Sounds as such can be observed only by the sense of hearing. It follows then that the attentive listening to voices is the first step to be taken.

Can any empirical knowledge of the voice be obtained by the mere listening to voices? If so, we ought now to be in possession of any facts which might be thus observed. Is it possible that information of this character is already a common possession of the vocal world, and yet that this information has never been applied in the investigation of the voice? This is exactly the case. Many facts regarding the voice have been observed so continually that they are a matter of common knowledge, and yet these facts have never been recorded in a scientific manner.

Consider, for example, this remark about a famous singer, made by one of the foremost musical critics of the United States: "Mme. T---- 's lower medium notes were all sung with a pinched glottis." How did this critic know that the singer had pinched her glottis? He had no opportunity of examining her throat with the laryngoscope, nor of observing her throat action in any other way. In fact, the critic was seated probably seventy-five feet from the artist at the time the tones in question were sung. The critic had only one means of knowing anything about the singer's throat action, and that was contained in the sound of the tones. There must therefore have been something in the sound of the tones which conveyed this information to the critical listener. For many years this gentleman had been in the habit of listening closely to singers, and he had found some way of estimating the singer's throat action by the character of the tones produced.

This same means of judging the manner of production from the sound of the tones seems to have been utilized nearly two hundred years ago.

Speaking of the most frequent faults of tone-production, Tosi remarks: "The voice of the scholar should always come forth neat and clear, without pa.s.sing through the nose or being choked in the throat." Mancini also speaks of the faults of nasal and throaty voice: "Un cantare di gola e di naso." A throaty tone, therefore, impressed these writers as being in some way formed or caught in the singer's throat. It may be set down as certain that no pupil ever explained to either of these masters how the objectionable sounds were produced. How then did Tosi and Mancini know the manner in which a throaty tone is produced?

We need not go back to the early writers to find out what is meant by a throaty tone. Fully as many throaty singers are heard nowadays as the old masters ever listened to. What do we mean when we say that a singer's voice is throaty? The answer to this question seems at first sight simple enough: The tones impress us as being formed in the singer's throat. But what conveys this impression? Something in the sound of the tone, of course. Yet even that is not enough. How can a tone, merely a sound to which we listen, tell us anything about the condition of the singer's throat during the production of the tone? Here again the answer seems simple: The listener knows that, in order to produce a tone of like character, he would have to contract his own throat in some way.

Here we have a highly significant fact about the voice. On hearing a throaty tone, the listener can tell how this tone is produced; he feels that he would have to contract his own throat in order to produce a similar tone. Let us carry this discussion a little further. How does the listener know this? Certainly not by actually singing a throaty tone. When seated in a concert hall, for example, and listening to a throaty singer, the hearer cannot rise from his seat, sing a few throaty tones himself, and then note how his throat feels. The critic just mentioned did not sing some notes with "pinched glottis" in order to learn how Mme. T---- sang her low tones. Evidently it is not necessary actually to imitate the singer; the hearer gets the same result by imitating the sounds mentally. In other words, when we hear throaty tones we mentally imitate these tones; thus we know that we should have to contract our own throats in order to produce similar tones.

But even here we cannot stop. To imitate the singer actually is one thing; mental imitation is something entirely different. In the first case, actual imitation, our muscular sense would inform us of the state of throat tightening. But in the case of mental imitation there is no actual tightening of the throat, nothing, at any rate, comparable to what takes place in actual imitation. There is then a dual function of the imagination; first, the mental imitation of the sound; second, the imaginary tightening of the throat. The a.n.a.lysis of the mental process must therefore be modified, and stated as follows: When we listen to a throaty tone we mentally imitate the tone; an imaginative function of the muscular sense informs us what condition the singer's throat a.s.sumes for the production of the tone.

A similar operation takes place in listening to nasal voices. An impression is conveyed by a nasal tone, through which the hearer is informed of a condition of tightness or contraction somewhere in the singer's nose.

The terms applied to the two most marked forms of faulty tone-production, nasal and throaty, are derived from impressions conveyed by the sounds of the tones. These names, nasal and throaty, refer to a feeling of tightness or contraction experienced in imagination by the hearer; in one case this feeling is located in the nose, in the other, in the throat. But the terms nasal and throaty are general descriptions of faulty tones. Each one covers a wide range of tone qualities. There is an almost infinite variety of throaty tones, and of nasal sounds as well. The knowledge of the voice obtained by listening to vocal tones is of equally wide extent. Every throaty tone, whatever its precise character, informs the hearer of the exact condition of the singer's throat in producing the tone. In short, every vocal tone is thus a.n.a.lyzed by the critical listener, and referred in imagination to his own throat. An insight into the singer's vocal action is imparted to the hearer through an imaginative process which always, of necessity, accompanies the attentive listening to vocal tones.

Every vocal tone awakens in the hearer a set of imagined muscular sensations. These sensations furnish the means for an exhaustive a.n.a.lysis of the operations of the voice. The production of tone therefore awakens two sets of muscular sensations, one actually felt by the singer, the other felt in imagination by the listener. The former are commonly known as the "singer's sensations"; but, as will be explained later, this expression is often very loosely applied. It is advisable on this account to give a new name to the singer's sensations, and also to give a name to the muscular sensations awakened in the hearer. Let us therefore call the sensations experienced by the singer in the production of tone the "direct sensations of tone." To the imaginary sensations of the hearer let us give the name, the "sympathetic sensations of tone."

These two terms will be used throughout the remainder of this work in the meanings here given to them.

Direct sensations of tone are the sensations actually felt by the singer as a result of the exercise of the vocal organs.

Sympathetic sensations of tone are the muscular sensations experienced in imagination by the hearer as a result of the listening to the tones of voices other than his own.

CHAPTER II

SYMPATHETIC SENSATIONS OF VOCAL TONE

A peculiar relation of sympathy exists between the human voice and the human ear. So intimate is this relation that the two might almost be considered as forming one complete organ. One aspect of this relation has already been noted, the guidance of the vocal organs by the sense of hearing. There is now to be considered another feature of this relation between voice and ear,--the a.s.sistance rendered by the vocal organs to the sense of hearing.

That a sub-conscious adjustment of the vocal organs may supplement the sense of hearing in the estimation of pitch is mentioned by Prof. Ladd.

Speaking of the ability, by no means uncommon, to tell the pitch of any musical note heard, Prof. Ladd says: "Such judgment, however, may be, and ordinarily is, much a.s.sisted by auxiliary discriminations of other sensations which blend with those of the musical tone. Among such secondary helps the most important are the muscular sensations which accompany the innervation of the larynx and other organs used in producing musical tones. For we ordinarily innervate these organs (at least in an inchoate and partial way)--that is, we sound the note to ourselves--when trying carefully to judge of its pitch." (_Elements of Physiological Psychology._)

Much more important in the study of the problem of tone-production are the adjustments of the hearer's vocal organs which were named the sympathetic sensations of tone. This peculiar auxiliary to the sense of hearing calls for the closest attention.

Sympathetic sensations of tone are awakened in the hearer through the mere listening to the sounds of the human voice. Vocal tones impress the listener's ear in a manner entirely different from any other sounds. Not only are the tones of the voice heard, just as other sounds are heard; in addition to this, every vocal tone heard is mentally imitated, and this mental reproduction of the tone is referred in imagination to the hearer's own vocal organs. Besides hearing the vocal tone as a sound pure and simple, the listener is also informed of the manner of throat action by which the tone is produced.

This mental imitation and judgment of vocal tones is not a voluntary operation. On the contrary it cannot even be inhibited. It is impossible for us to listen to the voices of those about us, even in ordinary conversation, without being to some extent aware of the various modes of tone-production.

This idea of the mental imitation of voices may impress us at first as highly mysterious. Sympathetic sensations of tone have been felt and noted, probably ever since the human voice and the human ear were developed. Yet the process is purely sub-conscious. It is performed involuntarily, without thought on the part of the hearer, even without any consciousness of the process. The hearer simply knows how the voices to which he listens are produced. A throaty voice simply sounds throaty; the hearer feels this, and pays no attention to the source of the information. We take it as a matter of course that a nasal voice seems to come through the speaker's nose. Why a certain quality of sound gives this impression we never stop to inquire. The impressions of throat action conveyed by other people's voices seem so simple and direct that n.o.body appears to have thought to a.n.a.lyze the psychological process involved.

This psychological process is found on a.n.a.lysis to be highly complex. In addition to the actual physical exercise of the sense of hearing, three distinct operations are performed in imagination. These are the mental imitation of the tone, the imagined adjustments of the vocal organs, and the imaginative exercise of the muscular sense. Although simultaneously performed, each of these four operations may be considered separately.
