REGISTERS AND LARYNGEAL ACTION
Probably no other topic of Vocal Science has been studied so earnestly as the registers of the voice. Yet on no other topic is there such wide diversity of opinion among theorists and investigators.
Very little is definitely known regarding the manner in which the subject of registers was treated by the old Italian masters. Suffice it to say here that the old masters did not refer the registers to changes in the laryngeal action. They were treated simply as different qualities of tone, each quality best adapted to be sung only in a portion of the voice's compass.
In the early decades of the nineteenth century the registers of the voice received much attention from vocal theorists, especially in Paris. Garcia's first published work, Mémoire sur la Voix humaine, was presented to the Academy of Sciences in 1840. This Mémoire gives the results of observations which Garcia made on his own pupils; it deals mainly with the position of the larynx during the singing of tones in the various registers. Garcia describes how the larynx is raised and lowered in the throat, according to the register in which the tones are produced. He also notes the position of the tongue and the soft palate.
Widespread interest was awakened by the account of Garcia's laryngoscopic investigations of the registers, published in 1855. The attention of the great majority of vocalists was at once drawn to the subject, and the actions of the vocal cords in the different registers were studied by many prominent physicians and voice specialists. Exhaustive treatises on the registers have since been published by Mme. Seiler, Behnke, Curwen, Mills, Battaille, Curtis, Holmes, and by a large number of other investigators.
All the results of the laryngoscopic investigation of the vocal action have been disappointing in the extreme. In the first place, no two observers have obtained exactly the same results. Writing in 1886, Sir Morell Mackenzie says: "Direct observation with the laryngoscope is, of course, the best method at our disposal, but that even its testimony is far from unexceptionable is obvious from the marvelous differences as to matters of fact that exist among observers. It is hardly too much to say that no two of them quite agree as to what is seen." (The Hygiene of the Vocal Organs, London, 1886.) Wesley Mills, in his latest work, endeavors to show a substantial agreement among the best equipped observers of the registers, but his attempt can hardly be called convincing. (Voice Production in Singing and Speaking, Philadelphia, 1906.) Opinions on the subject of registers, held by the leading voice specialists to-day, are fully as divergent as in 1886. Widely different statements are made by prominent authorities as to the number of registers, the vocal cord action by which each register is produced, and the number of notes which each one should properly include.
Another deficiency of the doctrine of registers is even more serious in its bearing on practical instruction. Not only have all investigators failed to define exactly what the correct laryngeal action is. Even if this were determined it would still be necessary to find means for imparting command of this correct action to the student of singing. Knowing how the vocal cords should act does not help the singer in the least to govern their action. What the vocal student wishes to know is how to cause the vocal cords to assume the correct position for each register. On this, the most important topic of mechanical Voice Culture, Vocal Science has shed no light whatever. A student may hear descriptions of the laryngeal action, and study the highly interesting laryngoscopic photographs of the vocal cords, until thoroughly familiar with the theoretical side of the subject. Even then, the student is no better able to control the vocal cord action than when profoundly ignorant of the whole matter.
This deficiency of Vocal Science is frankly recognized by one of the latest authoritative writers on the subject, Dr. Wesley Mills. On page 173 of his work just quoted, he advises students to hear the great singers, to note carefully the quality of tone which characterizes each register, and to imitate these qualities with their own voices. This advice may almost be described as revolutionary. Vocal theorists have always assumed that the correct action cannot be acquired by imitation. In this advice to rely on the imitative faculty for acquiring control of the laryngeal action, Dr. Mills abandons the basic principle of modern methods. Without exception, all instruction in singing is to-day based on the idea of mechanical tone-production. An entirely new theory of Voice Culture is involved in this advice of Dr. Mills.
Turning to practical methods of instruction, it is found that the subject of registers is very seldom treated in the manner suggested by the theoretical works on the voice. This would be, to make the "placing" of the voice in the different registers the exclusive subject of instruction for a certain number of lessons;—to train each register of the voice separately;—when the correct vocal cord action had been established in each register, to unite the different registers, and to correct any "breaks" which might have developed. Comparatively few teachers attempt to follow this course. The great majority treat the registers in a much less systematic fashion. A single half-hour lesson usually includes explanations and exercises on several topics of mechanical tone-production, as well as hints on agility, style, execution, etc. As merely one of this variety of subjects, the registers usually receive rather desultory attention.
Some teachers profess to ignore the subject of registers entirely. They maintain that, when properly trained from the beginning, the compass of the voice is one homogeneous whole; "breaks" and changes of quality are in their opinion merely the results of bad instruction. But the general belief of vocal authorities is overwhelmingly against these teachers. The condition which they describe is without doubt the ideal of vocal management; but the vast majority of teachers believe that this condition cannot be attained without some attention being paid to the individual registers.
