To the layman these precepts are so vague as to be almost unintelligible. But modern vocal teachers are convinced that the precepts sum up the most important means used by the old masters for imparting the correct vocal action. An interpretation of the precepts in terms intelligible to the modern student would therefore be extremely valuable. Many scientific investigators of the voice have sought earnestly to discover the sense in which the precepts were applied by the old masters. These explanations of the traditional precepts occupy a very important position in most modern methods of instruction.

There can be no question that the old masters were highly successful teachers of singing. Even leaving out of consideration the vocal achievements of the castrati, the singers of Tosi's day must have been able to perform music of the florid style in a masterly fashion. This is plainly seen from a study of the scores of the operas popular at that time. Empirical methods of instruction seem to have sufficed for the earlier masters. Not until the old method had been in existence for nearly one hundred and fifty years does an attempt seem to have been made to study the voice scientifically. In 1741 a famous French physician, Ferrein, published a treatise on the vocal organs. This was the first scientific work to influence the practices of vocal teachers.

For many years after the publication of Ferrein's treatise, the scientific study of the voice attracted very little attention from the singing masters. Fully sixty years elapsed before any serious attempt was made to base a method of instruction on scientific principles. Even then the idea of scientific instruction in singing gained ground very slowly. Practical teachers at first paid but little attention to the subject. Interest in the mechanics of voice production was confined almost entirely to the scientists.

In the early decades of the nineteenth century the mechanical features of voice production seem to have appealed to a constantly wider circle of scientists. Lickovius (1814), Malgaine (1831), Bennati (1830), Bell (1832), Savart (1825), brought out works on the subject. It remained, however, for a vocal teacher, Garcia, to conceive the idea of basing practical instruction on scientific knowledge.

Manuel Garcia (1805-1906) may justly be regarded as the founder of Vocal Science. His father, Manuel del Popolo Viscenti, was famous as singer, impresario, and teacher. From him Garcia inherited the old method, it is safe to assume, in its entirety. But for Garcia's remarkable mind the empirical methods of the old school were unsatisfactory. He desired definite knowledge of the voice. A clear idea seems to have been in his mind that, with full understanding of the vocal mechanism and of its correct mode of action, voices would be more readily and surely trained. How strongly this idea had possession of Garcia is shown by the fact that he began the study of the vocal action in 1832, and that he invented the laryngoscope only in 1855.

It must not be understood that Garcia was the first teacher to attempt to formulate a systematic scheme of instruction in singing. In the works of Mannstein (1834) and of Marx (1823) an ambitious forward movement on the part of many prominent teachers is strongly indicated. But Garcia was the first teacher to apply scientific principles in dealing with the specific problem of tone-production. He conceived the idea that a scientific knowledge of the workings of the vocal organs might be made the basis of a practical system or method of instruction in singing. This idea of Garcia has been the basic principle of all practical methods, ever since the publication of the results of his first laryngoscopic investigations in 1855.

Before attempting to suggest a new means of dealing with the problem of vocal management, it is well to ascertain how this problem is treated in modern methods of instruction. It would not be easy to overstate the importance assigned to the matter of tone-production in all modern systems of Voice Culture. The scientific study of the voice has dealt exclusively with this subject. A new science has resulted, commonly called "Vocal Science." This science is generally accepted as the foundation of all instruction in singing. All modern methods are to some extent based on Vocal Science.

To arrive at an understanding of modern methods, the two directions in which vocal theorists have approached the scientific study of the voice must be borne in mind: First, by an investigation of the anatomy of the vocal organs, and of the laws of acoustics and mechanics in accordance with which they operate. Second, by an analysis of the traditional precepts of the old Italian school in the light of this scientific knowledge.

As the present work demands a review of modern methods from the practical side only, it is not necessary to include a description of the vocal organs. It will be sufficient to describe briefly the manner in which scientific investigators of the voice treat the subject of the vocal organs.

The vocal mechanism consists of three portions,—the breathing apparatus, the larynx with its appendages, and the resonance cavities. Vocal scientists apply their efforts to finding out the correct mode of action of each portion of the mechanism, and to formulating rules and exercises by which these correct actions can be acquired and combined for the production of perfect tones. The analysis of the traditional precepts also conforms to this general plan; each precept is referred to that portion of the vocal apparatus to which it seems best to apply. The outline of the principles of modern methods contained in the following chapters follows this general scheme.
