A method of instruction in singing therefore consists primarily of a set of mechanical rules and directions for managing the voice, and secondarily of a series of exercises, both toneless and vocal, so designed that the student may directly apply in practising them the rules and directions for vocal management. It must not be understood however that the mechanical rules are applied only to the exercises specially designed for this purpose. These rules and directions are also intended to be applied to everything the student sings,—exercises, technical studies, and musical compositions.

It will be recalled that the review of the topics of modern vocal instruction covered three distinct types of materials. First, the purely mechanical doctrines, commonly regarded as the only strictly scientific principles of Voice Culture. These are, the rules for the management of the breath, of the registers, of laryngeal action, and of the resonance cavities, and also the directions for attacking the tone, and for forward emission. The second class of materials is held by strict adherents of the scientific idea to be purely empirical; this class includes the traditional precepts of the old Italian school, and also all the topics of instruction based on the singer's sensations. A third class of materials is found in the attempts to interpret the empirical doctrines in the light of the scientific analysis of the vocal action.

To enumerate and classify all the methods of instruction in vogue would be almost an impossibility. Absolutely no uniformity can be found on any topic. Even among the accepted doctrines of Vocal Science there are many controverted points. Five distinct schools of breathing are represented, two of breath-control. Of well worked-out systems of registers, at least twenty could be enumerated. Fully this number of theories are offered regarding the correct positions of the larynx, soft palate, and tongue. Two opposed theories are held as to nasal resonance. Further, the empirical doctrines are always stated so loosely that no real unanimity of view can be found on any one of them.

Every vocal teacher selects the materials of instruction from these controverted doctrines, but neither rule nor reason determines what materials shall be embodied in any one method. There is no coherence whatever in the matter. Further, there is no agreement as to which topics of instruction are most important. One teacher may emphasize breath-control and support of tone as the foundations of the correct vocal action, another may give this position to nasal resonance and forward placing. Yet both these teachers may include in their methods about the same topics. The methods seem entirely different, only because each makes some one or two doctrines the most important. In short, it might almost be said that there are as many methods as teachers.

Three fairly distinct types of method may be defined, depending on the class of materials adopted. At one extreme are found those teachers who attempt to follow strictly the scientific principles. These teachers generally profess to employ only the purely mechanical doctrines of Vocal Science, and to ignore all empirical interpretations of these doctrines. They generally devote a portion of every lesson to toneless muscular drills, and insist that their pupils practise every exercise in singing, with special attention to the throat action. These teachers attempt to follow a definite plan and order in the giving of exercises and rules. This systematic arrangement of instruction is, however, seldom followed out consistently with any one student. An important reason for this is considered in Chapter I of Part II.

A very different type of method is taught by many teachers who pay special attention to the empirical topics of instruction. Of course no teacher professes to teach empirically; on the contrary, every method is called scientific, no matter what materials it embodies. Indeed, a very little attention paid to breathing, attack, registers, and nasal resonance, is enough to relieve any teacher of the reproach of empiricism. The teachers now being considered touch to some extent on these topics; but most of their instruction is based on the traditional precepts, the singer's sensations, and the special vowel and consonant drills. In the first few lessons of the course they usually give some special breathing exercises, but almost always ignore breath-control. Not much is done for vocal control in the strictly muscular sense. Special "voice-placing" exercises are not used to any such extent as in the strictly scientific methods just described, the voice-placing work being usually done on vocalises, songs, and arias. No system whatever is followed, or even attempted, in the sequence of topics touched upon. The directions, "Breathe deeper on that phrase," "Bring that tone more forward," "Open your throat for that ah," "Feel that tone higher up in the head," may follow one after the other within five minutes of instruction.

Teachers of this type are frequently charged, by the strict advocates of mechanical instruction, with a practice commonly known as "wearing the voice into place." This expression is used to indicate the total abandonment of system in imparting the correct vocal action. It means that the teacher simply has the pupil sing at random, trusting to chance, or to some vague intuitive process, to bring about the correct use of the voice. To the vocal scientist, "wearing the voice into place" represents the depth of empiricism.

The great majority of teachers occupy a middle ground between the two types just described. Teachers of this class touch, more or less, on every topic of instruction, mechanical, empirical, and interpretive. Their application of most of the topics of instruction is not quite so mechanical as in the first type of method considered. The student's attention is always directed to the vocal organs, but the idea of direct muscular control is not so consistently put forward. As a rule, the attempt is made in the first stages of instruction to follow a systematic plan. Breathing, and perhaps breath-control, are first taught as muscular drills, and then applied on single tones. Attack is generally taken up next, then simple exercises in the medium register. Following this, the chest and head registers are placed, and the attention is turned to emission and resonance. But in most cases, when the pupil has covered three or four terms of twenty lessons each, all system is abandoned. The method from that time on is about of the type described as empirical.

It must be remembered that this classification of methods is at best very crude. It would not be easy to pick out any one teacher who adheres consistently to any of the three forms of instruction described. All that can be said is that a teacher usually tends somewhat more to one type than to another.

Further, the degree of prominence given to the idea of direct mechanical control of the voice does not classify a method quite satisfactorily. Without exception every teacher adheres to the prevailing idea, that the voice must be controlled and guided in some direct way,—that the singer "must do something" to cause the vocal organs to operate properly. All the materials of instruction, mechanical and empirical, are utilized for the sole purpose of enabling the student to learn how to "do this something."
