One may say that talking implies a series of associated reflexes, the parts associated being the respiratory, the laryngeal, and the resonance apparatus. Singing only approaches this condition of reflex action and habit after practice, and yet no air is perfectly sung except when the result is the outcome of a sort of new habit. Every song involves, the learning of new vocal habits. One forms a new habit of an athletic character all the more readily because of previous ones. A man learns to play one game of ball the better, usually, if he have already played at another, the reason being that he has only to modify the action of neuro-muscular mechanisms, not associate new mechanisms together to the same extent as in the formation of a habit of a widely different kind, as rowing a boat. At the same time, one must always unlearn something—break up old habits, to some extent. An opera singer often makes a failure of oratorio at first. The sets of reflexes or the habits, bodily and mental, which he has found valuable for the one form of art do not suit the other perfectly; nevertheless, the same materials are used, the reflexes are in the main the same. He must use preventions, or inhibitions, as the physiologists term them. Rather is it that he must avoid doing certain things—i.e., modify his neuro-muscular processes or reflexes, than form wholly new ones.
Were it not for reflexes and habits, learning would be so slow one lifetime would not suffice to make an artist. It must be apparent that habits and reflexes are Nature's ways of economizing energy. As the best have but a limited amount of energy, it should be the aim of every one who will not be a mere reckless spendthrift to economize, to make the most of what Nature has given him; hence the purpose of practice is not only to render success more certain and more perfect, but to make efforts tell to the fullest extent with as little expenditure of energy to the speaker or singer as possible. He sings or speaks best who attains the end with the least expenditure of energy.
It may with scientific accuracy be said that the object of the student should be to attain to the formation of correct habits in singing and speaking, and of the teacher to guide in this process. It follows that all practice by the beginner should be carried out only in the presence of one who knows the correct methods and can teach the student how to form his habits wisely. Practice alone may not only do little good, but, by the formation of wrong habits of production, be positively mischievous; yet a trainer of athletes often lays more restrictions on his ward as to when and how he shall practise, and exercises more supervision over it, than do some teachers of singing, in spite of the fact that the apparatus the singer or speaker uses is much more delicate, and wrong habits much more injurious.
The admonition "Practise, practise," is greatly overdone. The best results cannot be obtained in either singing, speaking, or playing, with the lengthy and necessarily more or less imperfect if not careless practice in which many students of music indulge. Better ten minutes with the whole attention of a fresh and interested mind given intelligently to a subject than ten hours of mere mechanical movement. It is a mistake to suppose that the acquirement of a sound technique is a purely mechanical process. We have shown that for all successful effort there must be the idea, and as soon as that fades, from weariness, etc., the practice should be discontinued. Students are not treated fairly when given exercises the meaning or purpose of which is not explained to them.
There is now more need than ever that the teacher of music or elocution should be intellectual and not mechanical in his methods. Technique is mechanism, but it should be mechanism subordinated to ideas. Technique is essential to art, but it is not art. Art is the soul, technique the body. The soul will be unknown to the world without technique; hence the author strives in this book to teach the principles on which a sound vocal technique rests, but only that what is best in the soul be not hidden, that the one noble or poetic thought shall be multiplied a thousand times—indeed, that if it be sufficiently worthy, it shall, like Tennyson's Brook, "go on forever." To believe, on the one hand, that the highest art can be attained with a very mediocre technique, and, on the other, that a perfect technique is the main object of musical training, are alike great and mischievous errors.
The author has been asked frequently such questions as the following: "When is the best time to practise? How long should a singer practise at one time, and for how long during a single day? Should one practise softly (piano) or vigorously (forte)?"—etc.
Fig. 53. By this diagram the author has attempted to give the reader some idea of the nature of the chain of processes involved in singing a single tone, from the time the eye looks on the note till the muscles concerned have given it utterance as a tone. The various nervous centres concerned are all in the brain (though the spinal cord supplies some subordinate centres). There are sensory centres, or those for the eye and the ear, and motor centres, or those sending the commands to the muscles involved. Further, these must be connected by paths not shown in detail, but represented by one centre spoken of as an "association" centre, which may also, possibly, have much to do with emotions, etc. But, at all events, the dependence of movements on ingoing messages or sensations is emphasized. The deaf cannot speak or sing, and the blind cannot read (ordinary) music. The defect may not be in either senses or muscles, but in the relating nervous mechanism between them. As explained in the body of the work, execution depends on at least two factors, sensations, or ingoing messages, and movements determined by these. Now the connection between the ingoing and the outgoing impulses is the most important and the least understood part, but the above diagram will at least serve to emphasize the fact that such connections exist, and that in a general way the result, performance, can be explained. No attempt has been made to trace the path of other sensory impulses than those from eye and ear, as this would make the diagram too complicated.
Often the student is puzzled by contradictory opinions on this subject. One celebrated prima donna states that she never practises more than one hour a day; another, equally distinguished, that she has often spent several hours in almost continuous strenuous practice. What is the student to believe, and whom to follow? No one, for no two persons are alike. All the above questions can be safely and surely answered in the light of science and experience combined, but such questions cannot be settled by the dictum of any singer, teacher, or writer, nor does the experience, in itself, of any one person furnish an adequate guide for others.
Investigation has shown that the use of muscles tends to the accumulation of the waste products of vital activity; that such accumulation is associated with the experience in consciousness of what we term "fatigue," and which is preceded by "weariness." The latter is a warning that the more serious condition is approaching, but is to be distinguished from another feeling not necessary to name, often present in unwilling youthful students, and for which various forms of treatment are sometimes tried so unsuccessfully that it is as well to discontinue study altogether.
