All that has come down to us of the oral traditions of the old school is summed up in a set of cogent phrases which are commonly known as the traditional precepts. These are, ‘open the throat,’ ‘sing on the breath,’ ‘sing the tone forward,’ and ‘support the tone.’ No literary authority can be given for the precepts, as they are not mentioned in any works published earlier than about 1830. It is possible that they do not date back much further than this. Perhaps they represent the first attempts made by vocal teachers to interpret their instruction according to the scientific ideas of vocal operation which were just beginning to become current about that time. How this could have been the case is readily seen. A perfect vocal tone sounds as though it floats on the breath. The correct singer’s throat seems to the hearer to be loose and open and the tone seems to be lodged in the front of the mouth. When the attention of vocal teachers began to be turned to the mechanical operations of tone production they might naturally have been led to observe first those salient features of tone which seem to point to a definite vocal action. Yet it is more likely that the old masters actually used the precepts in instruction merely to point out to their pupils these striking peculiarities in the sound of the perfect vocal tone. We know that they always held up before their students a high ideal of artistic singing. A use of the precepts in this way would be of great service in helping the students to hear how perfect singing should sound. To imitate successfully it is necessary in the first place to hear distinctly. Pointing out the marked characteristics of the perfect tone enables the ear to know what to listen for. It must be borne in mind that the old Italian method was never standardized. No such thing as a school of recognized authority, to whose principles all teachers were obliged to adhere, was ever evolved. Each master taught according to his own ideas, and no central authority or governing body ever undertook to lay out a standard method. Yet the old masters all followed the same general plan of instruction. In some of its aspects this plan is thoroughly understood. Students were taught to sing correctly and artistically solely through the exercise of their voices in actual singing. The materials used for vocal training were scales, exercises, and vocalises without and with words. These were without exception melodious, and the musical and artistic aspects of singing received attention from the beginning of instruction to the end. Singing was considered always on its _musical_ side and its _mechanical_ features were never touched upon. The voice was led on by a gradual progression from the easy to the difficult.
