The Psychology of Singing / A Rational Method of Voice Culture Based on a Scientific Analysis of All Systems, Ancient and Modern

by David C. Taylor

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.
