THROAT STIFFNESS AND INCORRECT SINGING

It is a lamentable fact that most of the singing heard nowadays gives evidence of throat stiffness. Perfect singing becomes more rare with each succeeding year. The younger generation of artists in particular evince a marked tendency to this fault of production.

Considered as a cause of faulty tone-production in singing, throat stiffness is due to only one influence, viz., the attempt to manage the voice by thinking of the vocal organs and their mechanical operations. Muscular tension due to nervousness, or to the unskilful nature of first attempts at singing, cannot be looked upon as causing a wrong vocal action. In the case of nervousness the lack of vocal command faithfully reflects the psychological condition of the singer; the imperfect response of the voice is normal to this condition. The stiffness due to first attempts is also perfectly normal. Moreover, both these forms of throat stiffness are temporary; they disappear when the cause, nervousness or lack of skill, is removed.

Throat stiffness does not necessarily destroy the musical character of the voice. Very many degrees and varieties of excessive throat tension are possible. The undue muscular exertion may be so slight in degree that the throat stiffness can be detected in the sound of the tones only by a highly sensitive and observant hearer. Or on the other hand, the muscles of the entire throat may be so powerfully contracted that the singer has only a very imperfect command of the voice. Between the two extremes, perfect tone-production and exaggerated stiffness, every conceivable shade of difference in degree of undue tension might be illustrated in the case of some prominent singer.

Faulty tone-production manifests itself in two ways; first, in its effects on the tones of the voice; second, in its effects on the singer's throat. Let us consider each of these topics separately.

_The Effect of Throat Stiffness on the Sound of the Voice_

In whatever degree throat stiffness is present, to just that extent the voice sacrifices something of its capabilities as a musical instrument. The voice can realize its full natural resources of beauty, range, power, and flexibility only when the throat is absolutely free from undue tension. As regards the quality of the tones, every phase of undue throat tension has its effect on the sound of the voice. These effects are always bad; the same voice is less beautiful when used in a stiffened condition than when perfectly produced. Throaty and nasal tones are always more or less harsh and offensive to the sensitive hearer. Further, the more pronounced the state of throat stiffness the more marked does the throaty or nasal quality become.

Under conditions of throat tension the range of the voice is almost always curtailed. The highest and lowest notes possible to any voice can be reached only when the throat is entirely free from stiffness. So also with regard to the varying degrees of power, undue tension prevents the singer from obtaining the extreme effects. A throaty singer's soft tones generally lack the carrying quality. Louder tones can be produced with a normally relaxed than with a stiffened throat.

Real flexibility of voice is impossible to a stiff-throated singer. Extreme rapidity and accuracy of muscular adjustments, the physical basis of coloratura singing, cannot be attained when the muscles are hampered by undue tension.

A distinct fault of production, the tremolo, is directly due to throat stiffness. A simple experiment illustrates the nature of the muscular action from which the tremolo results. "Set" the muscles of the arm by contracting the biceps and triceps with the utmost possible strength. With the arm in this stiffened condition flex and extend the forearm slowly several times. You will notice a pronounced trembling of the arm. Why a condition of muscular stiffness should cause the affected member to tremble is not well understood. But the fact admits of no question. It is highly probable that the tremolo is caused by a trembling of the vocal organs, due to muscular stiffness. The tones of a voice afflicted with tremolo always give evidence of extreme throat tension.

Another bad result of throat stiffness in tone-production is seen in the matter of intonation. Tones produced with a stiff throat are seldom in perfect tune. This subject will be more fully treated in a later chapter.

_Effects of Muscular Stiffness on the Throat_

Many of the muscles of the vocal organs, particularly the laryngeal muscles, are extremely small and delicate. Under normal conditions these muscles are fully capable of exerting the relatively small amount of strength required of them without strain or injury. But when the voice is used in a stiffened condition the delicate muscles of the larynx are obliged to contract with much more than their normal strength. To borrow an expression of the engineers, the throat muscles are then forced to carry an excessive load.

A balanced contraction of antagonist groups of muscles is the muscular basis of throat stiffness. When the voice is used in this condition each muscle of the vocal organs must put forth the amount of effort necessary to produce the desired effect under normal conditions, in addition to an effort equal to the counterbalancing pull of its antagonist muscle. An increase in the degree of throat stiffness demands a corresponding increase in the effort exerted by every muscle of the throat.

Over-exertion of muscles always results in strain and injury. The extent of the injury to the muscular tissues varies with the degree of excessive exertion and with the duration of the injurious exercise. An advanced stage of muscular strain is distinctly a pathological condition.

Tone-production in a state of throat stiffness is of necessity injurious to the muscles of the vocal organs. The delicate laryngeal muscles are specially subject to the injurious effects of strain. These effects vary in extent and character, according to the degree of throat stiffness, to the extent and duration of the faulty use of the voice, and to the individual characteristics of the singer. A very slight degree of undue tension may not sensibly injure the voice. Even a fairly marked condition of tension, such as is evidenced by the uniformly throaty quality of many baritones and mezzo-sopranos, may be persisted in for years without perceptibly straining the throat or destroying the musical value of the voice. But a misuse of the voice is bound, in the course of time, to show its injurious results on the throat. How many promising young singers are forced to abandon their careers in early life, at the time when their artistic and dramatic powers are just ripening to fruition! A misused voice "wears out" years before its time.

Most of the throat troubles of singers are directly caused by throat stiffness and muscular strain. Dr. Mills, among others, touches on this fact. "All the author's experience as a laryngologist tended to convince him that most of those evils from which speakers and singers suffer, whatever the part of the vocal mechanism affected, arise from faulty methods of voice production, or excess in the use of methods in themselves correct." (_Voice Production in Singing and Speaking_, Phila., 1906.)

For the purposes of artistic singing, a voice loses all its value when the injurious effects of throat stiffness become very pronounced. On this account singers are obliged to give up appearing in public before the condition reaches the extreme. It follows therefore that only in the case of public speakers do we see the extreme results of persistence in the wrong use of the voice. "Clergyman's sore throat" is the name usually applied to this condition. The sustained use of the voice, under conditions of extreme strain, is exceedingly painful both to the speaker and to the hearer.

Singers are usually unconscious of throat stiffness unless the condition be very pronounced. Neither the sense of hearing nor the muscular sense informs the singer of the state of tension. Accustomed to the sound of his own voice, the singer may be unaware of a throaty or nasal quality which he would instantly detect in another voice. This is also true of the muscular sensations of tone-production; habit makes the singer inattentive to the sensations caused by throat tension.

Throat stiffness always tends to become greater in degree; it is a self-aggravating condition. Even though very slight in its beginnings, the state of stiffness obliges the singer to put forth more than the normal effort in order to secure the desired effects. This increase of innervation is not confined to the muscles which need to be more strongly contracted. As Prof. Scripture points out, it also extends to the associated and antagonist muscles, that is, to all the muscles of the throat. Thus the stiffness is increased in degree. Still greater exertion is then required, resulting in still greater stiffness. This may go on for years, the voice gradually becoming less responsive to the demands of the singer.

Individual personal characteristics are an important factor in determining a singer's experience with throat stiffness. Some singers are so fortunately constituted as to be almost entirely free from the tendency to stiffen the throat. Others detect the tendency in its beginning and find no difficulty in correcting it. Still others habituate themselves to some manner of tone-production, and neither increase nor diminish the degree of stiffness. Even under modern methods of instruction, many artists are correctly trained from the start and so never stiffen their throats in any way.

Several traits of character are concerned in determining the individual tendency to throat stiffness. Nervous temperament, keenness of ear, artistic and musical endowment, each has its influence in this connection.

The great prevalence of throat stiffness among present-day singers is due primarily to the idea of mechanical vocal management as the basis of instruction in singing. Not only are modern methods intrinsically worthless, in that a correct use of the voice cannot be attained by the application of mechanical rules. Worse than this, the means used for training the voice are such as to defeat their own purpose. At every instant of instruction the student's attention is expressly turned to the vocal organs and to the mechanical operations of the voice. The only possible result of this kind of vocal instruction is to stiffen the throat and so to render the correct vocal action an impossibility.

A peculiar contradiction is presented by the modern vocal teacher; his artistic conception of singing is utterly at variance with his ideas of mechanical tone-production. It may safely be said that the vast majority of vocal teachers are thoroughly conversant with the highest standards of artistic singing. They know what effects their pupils ought to obtain. But the means they use for enabling the pupils to get these effects have exactly the contrary result. When the student tries to open the throat this obstinate organ only closes the tighter. Attempting to correct a tremolo by "holding the throat steady" causes the throat to tremble all the more.

Modern voice culture, in its practical aspect, is a struggle with throat stiffness. Everything the student does, for the purpose of acquiring direct command of the voice, has some influence in causing the throat to stiffen. Telling the student to hold the throat relaxed seldom effects a cure; this direction includes a primary cause of tension,--the turning of attention to the throat. All the teacher can do to counteract the stiffening influence is to give relaxing exercises. These are in most cases efficacious so long as constructive instruction is abandoned, and the relaxing of the throat is made the sole purpose of study. But soon after positive instruction is resumed the tendency to stiffen reappears. As lesson follows after lesson, the stiffness becomes gradually, imperceptibly more pronounced. At length the time again comes for relaxing exercises.

A single repetition of this process, relaxing the throat and then stiffening it again, may extend over several months of study. During this time the student naturally learns a great deal about music and the artistic side of singing, and also improves the keenness of the sense of hearing. This artistic development is necessarily reflected in the voice so soon as the throat is again relaxed.

It usually happens that students change teachers about the time the voice has become unmanageably stiff. In this condition the student, of course, sings rather badly. A marked improvement in the singing generally results from the change of teachers. This is easy to understand because the new teacher devotes his first efforts to relaxing the stiffened throat. Later on this improvement is very likely to be lost, for the second teacher has nothing more of a positive nature to offer than the first.

Vocal teachers in general seem to be aware of the fact that mechanical instruction causes the student's throat to stiffen. A much-debated question is whether "local effort" is needed to bring about the correct vocal action. The term local effort is used to describe the direct innervation of the throat muscles. A logical application of the mechanical idea absolutely demands the use of local effort. This is the main argument of the local-effort teachers.

Those teachers who discountenance local effort have only their own experience to guide them. They simply know that local effort results in throat stiffness. Yet these teachers have nothing to offer in place of the mechanical management of the vocal organs. Even though aware of the evil results of local effort, they yet know of no other means of imparting the correct vocal action. The weakness of the position of these teachers is well summed up by a writer in _Werner's Magazine_ for June, 1899: "To teach without local effort or local thought is to teach in the dark. Every exponent of the non-local-effort theory contradicts his theory every time he tells of it." To that extent this writer states the case correctly. Every modern vocal teacher believes that the voice must be consciously guided in its muscular operations. Until this erroneous belief is abandoned it is idle for a teacher to decry the use of local effort.
