The Child-Voice in Singing Treated from a physiological and a practical standpoint and especially adapted to schools and boy choirs

very lightly. This will insure the uninterrupted use of the thin register to the lowest note. Let them now sing up and down the scale several times, observing the same caution when notes below C or B are sung, and also insisting that no push be given to the upper notes. Now, first excusing monotones, let the other pupils in the room sing first down the scale and then up, imitating the quality and softness of tone of the picked class. Recollect, you are asking something of your pupils which it is perfectly easy for them to do. It may be that the strength of well-formed habits stands opposed to the change, but, on the other hand, every musical instinct latent, or partly awakened, is becoming alert and proving the truth of your teaching better and faster than can any finespun reasoning. Illustrate the difference in tone-quality between the thick and thin register as often as it is necessary, to show your pupils what you wish to avoid and how you wish them to sing. When in doubt whether or not the thin quality is being sung, require softer singing until you are sure. It is better to err upon the side of soft singing than to take any chances.
In time teachers will become quick to detect the change in register, and in time also the pupils who are trained to sing in the thin voice will yield to the force of good habit, as they once did to bad habit, and seldom offend by too loud or too harsh tone.
The inquiry may naturally have arisen ere this: Are syllables, i.e., do, re, mi, etc., to be used, or the vowel-sounds? It is immaterial from the standpoint of tone-production, whether either or both are used. Until children are thoroughly accustomed to sing softly, they will be kept upon the thin register more easily when singing with a vowel-sound, than when using the syllables. The reason is that the articulation of the initial consonants of the syllables requires considerable movement of the organs of speech, viz., the tongue, lips, etc., and these movements are accompanied by a continually-increasing outrush of air from the lungs, occasioning a corresponding increase in the volume of sound. Adult voices show the same tendency to increase the volume of tone when first applying words to a passage practiced pianissimo with a vowel-sound. It is advisable then to sing scales and drill upon them with a vowel-sound, and to recur to the same drill for a corrective, when a tendency to use the thick voice in singing note exercises appears.
Scale drill may be carried on as follows: If the scales are written upon a blackboard staff, they may from day to day be in different keys. It is a very easy matter to extend the scale neither above nor below the pitches within which it is desired to confine the voice. For example, the scale of E or F may be written complete, that of G as follows:

or A
or B♭ 
and so on. Now let the teacher with a pointer direct the singing of the class upon the selected scale in such a manner as to secure the desired result in tone, and incidentally a familiarity with pitch relations, etc. Of course, if charts are used the trouble of writing scales is saved, only it is advised that the notes lying outside the prescribed compass be omitted in the lower grades entirely, and in the upper until the habit of good tone is established, when, of course, the tones may be carried below E with safety. The extent and variety of vocal drill which can be given with a pointer and a scale of notes is wonderful; but nothing more need be now suggested, than those exercises which are peculiarly intended to secure good tone, and fix good vocal habits, although it must be evident that all such drill is very far-reaching in its effects.
A few exercises which are very simple are here suggested. First, taking the scale of

for example. Let the teacher, after the pitch of the keynote is given to the class, place the pointer upon F, and slowly moving it from note to note, ascend and descend the scale, the class singing a continuous tone upon some vowel, o for instance. The pointer should be passed from note to note in such a manner that the eye can easily follow it. If the notes are indicated to the class by a series of dabs at the chart or blackboard, the pointer each time being carried away from the note several inches, and then aimed at the next note and so on, the eye becomes weary in trying to follow its movements, and the mental energy of the pupils, which should be concentrated upon tone, is wasted in watching the gyrations of the pointer. If, on the other hand, the pointer is made to glide from note to note, passing very quickly over intervening spaces, then the eye is not wearied in trying to follow it. These directions may seem pretty trivial, but practical experience has proved their importance. The vowel o is suggested because it has been found easier to secure the use of the head-register with this vowel than with ah, when it is sought to break up the habit of singing loudly and coarsely.
The term continuous tone used to describe the style of singing desired is meant literally. If the class in this scale-drill all stop and take breath at the same time, making frequent breaks in the continuity of the tone, there will be found with each new attack a tendency to increase in volume of sound. For certain reasons, which will be explained in the chapter on breath-management, the attack of tone will become more and more explosive, demanding constant repression. This irritating tendency may, in a short time, be almost entirely overcome, if, instead of letting the class take breath and attack simultaneously, each pupil is told to take breath only when he or she is obliged to, and then at once and softly to join again with the others. This will effect the continuous tone, useful not alone as a corrective for the tendencies to loud singing, but also to establish good breathing-habits.
