Turning now to the question of nasal quality, strictly speaking, tones of this objectionable character always awaken the sympathetic sensations of contraction somewhere in the nose. Why such a contraction should cause this unpleasant sound of the voice is a profound mystery. Perhaps wrong tension of the soft palate exerts an influence on the actions of the vocal cords; or it may be that the form of the nasal cavities is altered by the muscular contraction. This aspect of the vocal action has never been scientifically investigated. The sympathetic sensation of nasal contraction or pinching is at any rate very pronounced. Curiously, this sympathetic sensation is cited as an argument in favor of their respective theories, by both the advocates and the opponents of nasal resonance. _Sympathetic Sensations and Breath-Control_ Certain forms of exaggerated throat stiffness are frequently held to indicate the need of breath-control. The faulty vocal action in question is analyzed by the breath-control advocates substantially as follows: "Owing to the outflow of the breath not being checked at the proper point, the entire vocal mechanism is thrown out of adjustment. The singer exerts most of his efforts in the endeavor to prevent the escape of the breath; to this end he contracts his throat and stiffens his tongue and jaw. His tones are forced, harsh, and breathy; they lack musical quality. His voice runs away with him and he cannot control or manage it. In the attempt to obtain some hold on his voice he 'reaches' for his tones with his throat muscles. The more he tries to regain control of the runaway breath the worse does his state become." This extreme condition of throat stiffness is unfortunately by no means rare. So far as concerns the sympathetic sensations awakened by this kind of singing the condition is graphically described by the breath-control advocates. But the conclusion is entirely unjustified that this condition indicates the lack of breath-control. Only the preconceived notion of breath-control leads to this inference. The sympathetic sensations indicate a state of extreme muscular tension of the throat; this is about the only possible analysis of the condition. * * * Empirical impressions of vocal tones determine the character of most present-day instruction in singing. This means no more than to say that throughout all vocal training the teacher listens to the pupil's voice. The impressions of tone received by the teacher's ear cannot fail to inform the teacher of the condition of the pupil's throat in producing the voice. For the teacher to seek to apply this information in imparting the correct vocal action to the pupil is inevitable.
