In the early years of the nineteenth century the results of scientific investigation of the voice began to attract the attention of the most enlightened vocal teachers. There was indeed no dissatisfaction with the methods of instruction then in vogue. Yet a general feeling can be noted by a student of the literature of the subject as setting in about that time, a feeling that systems of voice culture might be improved by applying to them the results of the most recent scientific discoveries. Two important works by vocal teachers may be cited in this connection, _Die Kunst des Gesanges_, by Adolph Bernhard Mark (1826), and _Die grosse italienische Gesangschule_, by Heinrich F. Mannstein (1834). In both of these books the point of view generally held at that time is clearly indicated. While the old Italian method was held to be thoroughly satisfactory in every respect, there is a desire to explain this method and to place it on an assured basis of demonstrated scientific principles. No thought of direct vocal management as a necessity, or even as a possibility, can be discovered in these two works. Manuel García (1805-1906), the vocal teacher who contributed most to the promulgation of the scientific idea, had at the beginning of his career exactly the same plan as Mannstein and Mark. His father, Manuel del Popolo Viscenti, was one of the most eminent musicians of the time. Famous as singer, teacher, impresario, and composer, the older García was in possession of all the traditions of the Italian school. From his father García received the traditional method in its entirety. Retiring from the operatic stage in 1832, García took up actively the profession of voice culture. Even as early as this he had definitely formulated a plan for the improvement of vocal methods. Yet at that time he had in mind nothing of the nature of a sweeping change. In the preface to his first important work, _École de García_, 1847, he stated that his intention was ‘to reproduce my father’s method, attempting only to give it a more theoretical form, and to connect results with causes.’ With this seemingly modest program García could not rest content. His ambition to penetrate all the mysteries of the voice led him to master the anatomy of the throat, as well as what was then known of acoustics. He was impatient to know what actually takes place in the larynx during the production of tone. After several years of experimenting he finally succeeded in viewing his own vocal cords by means of a little mirror held in the back of the throat. His announcement of his invention was published in the proceedings of the Royal Society of London in May, 1855.
