HEAD RESONANCE
Whether or not the head cavities act as resonators is one of the many mooted points in voice training. Those who believe they do are much in the majority, but those in the minority are equally confident they do not. What are the arguments? That there is a sensation in the head cavities when singing in the upper part of the compass no one can deny. Does it affect tone quality? The minority offers the argument that it cannot do so because the soft palate automatically rises in singing a high tone, thus closing the passage through the nose. On the other side it is argued, and rightly, that the soft palate can be trained to remain low in singing high tones. But whether the soft palate is high or low does not settle the matter. It is not at all necessary that breath should pass through the nasal cavities in order to make them act as resonators. In fact it is necessary that it should not. It is the air that is already in the cavities that vibrates. All who are acquainted with resonating tubes understand this. Neither is it necessary that the vibrations should be transmitted to the head cavities by way of the pharynx and over the soft palate. They may be transmitted through the bones of the head. John Howard proved this, to his satisfaction at least, many years ago.
I recall that in working with Emil Behnke he used an exercise to raise the soft palate and completely close the channel, yet no one can deny that his pupils had head resonance. There are certain facts in connection with this that are hard to side-step. Plunket Greene once told me that at one time he lost the resonance in the upper part of his voice, and on consulting a specialist he found a considerable growth on the septum. He had it removed and at once the resonance returned. Other equally strong arguments could be offered in support of the claim that the head cavities do act as resonators. At any rate the high or low palate is not the deciding factor.
Too much cannot be said on the subject of interference, or resistance. So long as there is any of it in evidence it has its effect on tone quality. It is the result of tension, and tension is a mental impulse of a certain kind. Its antidote is relaxation, which is a mental impulse of an opposite nature. It is necessary for most singers to work at this until long after they think they have it.
In preparing the head voice the student must begin with a tone that is entirely free from resistance and build from that. In a large majority of voices it means practicing with a light, soft tone. A voice that cannot sing softly is not rightly produced. While the student is working for the freedom which will give him a good half voice he is preparing the conditions for a good full voice. The conditions are not right for the practice of full voice until the last vestige of resistance has disappeared. The light voice is as necessary to artistic success as the full voice. The singer must have both, but he must never sacrifice quality for power.
In the female voice the readjustments of the mechanism known as changes of register usually occur at about
In many lyric soprano voices I have found the same readjustment at the B and C above the staff
I have also noted in many bass voices a similar change of adjustment at the E and F below the bass clef
It would seem therefore, that in a majority of voices until an even scale has been developed, that these readjustments appear at about the E and F and B and C throughout the vocal compass. The exceptions to this rule are so numerous however, that it can scarcely be called a rule. Some voices will have but one noticeable readjustment, and it may be any one of the three.
In some voices the changes are all imperceptible. In others, due to wrong usage, they are abrupt breaks. In every instance the teacher must give the voice what it needs to perfect an even scale. There should be no more evidence of register changes in the vocal scale than in the piano scale.
Leaving the lower two changes for the moment, let us consider the one at the upper E and F. This one is so common among sopranos that there are few who have not one, two, or three weak tones at this point. To avoid these weak tones many are taught to carry the thicker tones of the middle register up as far as they can force them in order to get the “big tone” which seems to be the sole aim of much modern voice teaching. The victims of this manner of teaching never use the real head voice, and one thing happens to them all. As time goes on the upper voice grows more and more difficult, the high tones disappear one by one, and at the time when they should be doing their best singing they find themselves vocal wrecks. Some of them change from soprano to alto and end by that route.
Now these are not instances that appear at long intervals. They are in constant evidence and the number is surprisingly large. The cause is ignorance of how to treat the upper voice, together with an insane desire for a “big tone” and a lack of patience to await until it grows. The incredible thing is that there is a teacher living whose ear will tolerate such a thing.
Now there is a way to develop the head voice that gives the singer not only the full power of his upper voice, but makes it free, flexible and vibrant, a sympathetic quality, a perfect messa di voce, and enables him to sing indefinitely without tiring his voice. He must learn that it is possible to produce a full tone with a light mechanism. This is the natural way of producing the head voice. Further, the light mechanism must be carried far below the point where the so called change of register occurs.
Every voice should have a head register, and it may be developed in the following way. With altos and sopranos I start with this exercise
Altos should begin at A.
The student should neither feel nor hear the tone in the throat. Therefore he should begin with a soft oo. The throat should be free, lips relaxed but slightly forward. There should be no puckering of the lips for oo. The tone should seem to form itself around the lips, not in the throat. In the beginning the exercise must be practiced softly. No attempt must be made to increase the power, until the tone is well established in the light mechanism. When the oo can be sung softly and without resistance as high as E flat use the same exercise with o.
The next step is to blend this light mechanism with the heavier mechanism. It may be done in this way,
Sing this descending scale with a crescendo, always beginning it pp. It should be practiced very slowly at first, and with portamento. Carrying the head voice down over the middle and the middle down over the lower will in a short time blend all parts of the voice, and lay the foundation of an even scale. The exercise should be transposed upward by half steps as the voice becomes more free until it reaches F or F sharp.
The next step is the building process. Use the following:
Altos should begin at A. In practicing these swells great care must be taken. Tone quality is the first consideration, and the tone must be pressed no further than is possible while retaining the pure singing quality. Where voices have been forced and are accustomed to sing nothing but thick tones this building process is sometimes slow. The student finds an almost irresistible tendency to increase the resistance as he increases the power of the tone. Therefore the louder he sings the worse it sounds. This kind of practice will never solve the problem. When the student is able to swell the tone to full power without increasing the resistance the problem is solved.
The progress of the student in this, as in everything in voice training, depends upon the ear of the teacher. The untrained ear of the student is an unreliable guide. The sensitive ear of the teacher must at all times be his guide. The belief that every one knows a good tone when he hears it has no foundation in fact. If the student’s concept of tone were perfect he would not need a teacher. He would have the teacher within himself. Every one knows what he likes, and what he likes is of necessity his standard at that particular time, but it is only the measure of his taste and may be different the next day.
All things in voice training find their court of last resort in the ear of the teacher. All other knowledge is secondary to this. He may believe any number of things that are untrue about the voice, but if he have a thoroughly refined ear it will prevent him from doing anything wrong. His ear is his taste, his musical sense, and it is his musical sense, his musical judgment, that does the teaching.
So in building the head voice the teacher must see to it that musical quality is never sacrificed for power. A full tone is worse than useless, unless the quality is musical and this can never be accomplished until the vocal instrument is free from resistance.
Exercise No. 3 should be transposed upward by half steps, but never beyond the point at which it can be practiced comfortably.
As tension shows most in the upper part of the voice the student should have, as a part of his daily practice, exercises which release the voice as it rises. Use the following:
Begin with medium power and diminish to pp as indicated. The upper tone must not only be sung softly, but the throat must be entirely free. There must be no sense of holding the tone.
Transpose to the top of the voice.
No. 5 is for the same purpose as No. 4 but in an extended form. Begin with rather full voice and diminish to pp ascending. Increase to full voice descending. Continue the building of the upper voice using the complete scale.
Thus far in preparing the head voice we have used the vowels oo and o. We may proceed to the vowel ah in the following way. Using Ex. No. 6 first sing o with loose but somewhat rounded lips. When this tone is well established sing o with the same quality, the same focus, or placing without rounding the lips. It amounts to singing o with the ah position. When this can be done then use short u as in the word hum. This gives approximately the placing for ah in the upper voice. When these vowels can all be sung with perfect freedom transpose upward by half steps.
In No. 7 when the crescendo has been made on the upper tone carry the full voice to the bottom of the scale.
This is another way of blending the different parts of the voice. It should be sung portamento in both directions. When sung by a female voice it will be Middle, Head, Middle as indicated by the letters M, H, M. When sung by the male voice it will be Chest, Head, Chest as indicated by the letters C, H, C. Transpose upward by half steps.
When the foregoing exercises are well in hand the head voice may be approached from the middle and lower registers in scale form as in the following:
The fact that male voices are more often throaty in the upper register then female voices calls for special comment.
The following diagram showing the relationship of the two voices will help to elucidate the matter.
I have here used three octaves of the vocal compass as sufficient for the illustration. Remembering that the male voice is an octave lower than the female voice we shall see that the female voice is a continuation, as it were, of the male voice; the lower part of the female compass overlapping the upper part of the male compass, the two having approximately an octave G to G in common. Further it will be seen that both male and female voices do about the same thing at the same absolute pitches. At about E flat or E above middle C the alto or soprano passes from the chest to the middle register. It is at the same absolute pitches that the tenor passes from what is usually called open to covered tone, but which might better be called from chest to head voice. There is every reason to believe that the change in the mechanism is the same as that which occurs in the female voice at the same pitches. That there is oftentimes a noticeable readjustment of the mechanism in uncultivated voices at these pitches no observing teacher will deny, and these are the voices which are of special interest to the teacher, and the ones for which books are made. It will be observed that this change in the male voice takes place in the upper part of his compass instead of in the lower, as in the female voice. This change which is above the compass of the speaking voice of the tenor or baritone, adds greatly to its difficulty. For this reason the training of the male head voice requires more care and clearer judgment than anything else in voice training.
In treating this part of the female voice we have learned that if the heavy, or chest voice, is carried up to G or A above middle C it weakens the tones of the middle register until they finally become useless. Then the chest tones become more difficult and disappear one by one and the voice has no further value. Identically the same thing happens to the tenor who, by reason of sufficient physical strength forces his chest voice up to G, A, or B flat. He may be able to continue this for awhile, sometimes for a few years, but gradually his upper tones become more difficult and finally impossible and another vocal wreck is added to the list.
In restoring the female voice that has carried the chest voice too high it is necessary to carry the middle register down, sometimes as low as middle C until it has regained its power. The tenor or baritone must do essentially the same thing. He must carry the head voice, which is a lighter mechanism than the chest voice, down as low as this c
using what is often called mixed voice. When the pitches
are practiced with a sufficiently relaxed throat the tone runs naturally into the head resonator with a feeling almost the equivalent of that of a nasal tone, but this tone will be in no sense nasal. It will be head voice.
