These are matters of judgment. But when I am told, as I was by a young girl, that she was being taught to centre the tone-vibrations "back of her eyes," all I can do is to throw up my hands and exclaim, "O voice-production, what crimes are committed in thy name!" Yes--there should be a Rescue League, or a Society for the Prevention of Cruelty to Singers.

CHAPTER VII

REGISTERS OF THE VOICE

The subject of vocal registers is a difficult one--difficult to understand and, when understood, difficult to make intelligible to others. In fact, it is so difficult that some people get rid of it by calmly a.s.serting that there are no registers. This is unfortunate, because the blending of the registers, the smoothing out of the voice where one register pa.s.ses over into another, the elimination of the "break" between them, is one of the greatest problems which the teacher of voice-production is obliged to solve. Like so many other branches in the art of voice-production, the subject is complicated by initial misunderstandings. Numerous people suppose, for example, that the vocal registers are synonymous with the different kinds of voices, and speak of the alto, soprano, ba.s.s or tenor register as if register stood for quality, which it does not. Another complication results from the fact that certain phenomenal voices, chiefly tenor, literally rise superior to the law of vocal registers. Thus, a phenomenal tenor like Duprez sang with ease the whole tenor range, including the high C, in the powerful, vibrant "chest" register, whereas the average tenor, while producing a great portion of his voice in the chest register, is obliged at a certain point in the ascending scale to pa.s.s into the "middle" and beyond that into the "head" register.

The breaks that occur in average voices at certain points of the scale have established the divisions of the voice into registers. These breaks can be accounted for on scientific grounds; and if the physiology of voice-production had done no more than explain the why and wherefore of vocal registers, it would have justified itself through this alone.

Suppose there were a man able to produce the entire male vocal compa.s.s, from deepest ba.s.s to highest tenor. While for every note throughout the entire compa.s.s there would be subtle changes in the adjustment of the vocal tract, the following also would be true:--That, beginning with the lowest note and throughout the first octave of his voice, the changes in the adjustment of the vocal tract would not alter the general character of the adjustment for that octave; that, on entering the second octave, there would be a tendency toward change in the general adjustment of the vocal tract; while, for the production of the remaining notes above, an almost startling change in the adjustment of the vocal tract would take place. The same would be true if a woman, capable of producing the entire female vocal compa.s.s, were to begin with the lowest contralto and sing up to the highest soprano tone. It is the general character of the adjustment of the vocal tract for a certain range of notes in the vocal scale that determines each register, the two princ.i.p.al changes in adjustment causing two breaks in the smooth progression of the voice.

Allowing for the fact that the male voice is an octave below the female voice, but in all other respects corresponds with it in range, the adjustment of the vocal tract throughout each register is the same for both men and women singers. There is, I fear, a prevalent notion on the part of the musical public that each voice has its own separate registers; that, for example, the registers of the soprano voice are at different points of the scale from those of the alto, and those of the tenor at different points from both of these. But this is not the case.

Always allowing for the octave difference between the male and female voice, the registers for all voices are at fixed points of the scale and are, or should be, sung by all voices with the same adjustment of the vocal tract. A few examples will make this clear.

The lowest register for female voice is:

[Music: F3-F4]

that for male voice:

[Music: F2-F3]

i.e., an octave lower. These are the first eight notes of the alto of the female voice and of the ba.s.s of the male voice. Alto and ba.s.s sing these notes with precisely the same adjustment of the vocal tract. The vocal cords in this register vibrate along their entire length, the s.p.a.ce between them, also the "cup" and the general adjustment of the vocal tract, are open. A good soprano can come down into this register as far as [Music: C4] and a good tenor as far as [Music: C3], and when these voices come down into this register they too sing with the same adjustment of the vocal tract as is used for the same tones by alto and ba.s.s. This, therefore, const.i.tutes the lowest register for all voices--not because it consists of certain notes, but because these notes require the same general adjustment of the vocal tract for their production by all voices.

When it comes to the next or middle register:--[Music: F4-F5] for female voices (and an octave below for male voices), soprano and tenor sing through this entire register with ease, using a slightly different adjustment of the vocal tract from that which they employed when they went down into the lowest register. The ordinary alto stops at C in this register, as does also the ba.s.s at an octave lower. When they enter it their vocal tract adjusts itself to it and corresponds with the adjustment employed in it by soprano and tenor. In this register the vocal cords still vibrate along their entire length, but as the voice progresses upward, they show a tendency to shorten the glottic c.h.i.n.k, and the cup, as well as the adjustment of the entire vocal tract, tends to become less open. It is the register of transition, placed between the lowest and highest, as if to bridge over the interval.

The highest register: [Music: F5-C6] (an octave lower for male voice) calls for an extraordinary change in the adjustment of the vocal tract. The vocal cords are pressed tightly together at the rear and sometimes both at the rear and front. These portions thus cease to vibrate. Only the small free parts vibrate and these only at the edges.

As the voice progresses up the scale the stop action ceases, the elliptical opening and the cup become smaller, and the entire vocal tract is, comparatively speaking, contracted. This register practically belongs only to sopranos and tenors. For example, although some baritones are capable of adjusting their vocal tracts to this register, their voices lose the baritone timbre, take on a feminine quality, and become male altos.

In other words, there are three registers, and they correspond for all voices, but certain voices sing more in one register than in the others.

Thus, the lowest register is the special province of the alto and the ba.s.s; soprano and tenor can come down only a few notes into it. The middle and the highest registers are the special province of soprano and tenor. The ordinary alto and ba.s.s can come up only part way into the middle register and cannot follow soprano and tenor at all into the highest.

The division of the registers which I have made is subject to many practical exceptions, which so far I have avoided mentioning, because I wanted to fix in the reader's mind the fact that the registers are the same for all voices and are determined by the special adjustment of the vocal apparatus required for their production, and not by voice-quality.

Now and then in a generation there may appear upon the scene a singer, usually tenor, who for his high notes is not obliged to adopt the somewhat artificial adjustment required by the highest register, but can sing all his tones in the easier adjustments of the lowest or middle register. But he is a phenomenon, the exception that proves the rule.

Another practical exception to my rigid division of the registers is furnished by the overlapping of registers, the capacity of a singer to produce the lower notes of one register with the vocal adjustment employed for the higher notes of the register below, and vice versa; so that where the registers meet there are possibly some half a dozen optional notes. Most ba.s.ses and baritones, for example, sing only in one register, that is, they carry the vocal adjustment for the lowest register into the notes they are able to sing in the register above.

These exceptions will be considered later. At present, in order to treat this difficult subject in something that at least approaches an elementary manner, it is necessary to make the division of the vocal scale into registers a somewhat rigid one.

It is, then, the three different adjustments of the vocal tract which determine the three divisions of the vocal scale and likewise the positions or registers for each division. The basis, therefore, for the division of voice-production into registers is not haphazard, but rests on the science of physiology. That there are not separate registers for men and women is due to the fact that men's voices run parallel to those of women at an interval of an octave below, and that, note for note, the adjustment of the male vocal tract is the same as that of the female vocal tract an octave above. For this reason ba.s.ses and baritones, although singing an octave below contraltos and altos, sing in the same registers; for this reason also, tenors, although singing an octave below sopranos, employ the same registers. I am, of course, speaking of average voices, not of phenomenal ones.

Mackenzie has defined a register as a series of tones of like quality producible by a particular adjustment of the vocal cords. Mills defines register as a series of tones of a characteristic clang, timbre, color or quality due to the employment of a special mechanism of the larynx in a particular manner. Both definitions practically mean the same thing.

What I object to in them is their use of the word "quality," and Mackenzie's limitation of the adjustment to the vocal cords and Mills'

to the larynx. The adjustment takes place throughout the entire vocal tract. Indeed, one of the claims I make for this book is, that it does not limit the voice-producing factor to the vibrations of the vocal cords, but while recognizing the importance of these, also considers the importance of the rest of the vocal tract in relation to them. Other writers hold that voice is produced solely by the vibrations of the vocal cords, and that the rest of the vocal tract is concerned merely with determining the timbre of the voice. But I do not limit the function of the vocal tract below and above the cords simply to voice quality. To produce a given tone requires not only vibration of the cords but an adjustment along the entire tract and especially a change in the size and shape of the cup s.p.a.ce. If one wished to be exasperatingly accurate one might say that each adjustment const.i.tuted a register, and that in every voice there were as many registers as there are tones. But surveying the progress of the voice up the vocal scale, and as a whole, it is found that up to a certain point the general character of adjustment within the vocal tract is the same, that beyond that point there is a change to another adjustment of a general character, and further beyond still another--in other words, that there are three registers.

Some writers recognize only two physical changes in the mechanism of the vocal tract and consequently only two registers instead of three. They dispense entirely with the middle register because the general change there in the adjustment within the vocal tract is not, in their opinion, sufficient to determine a new register. In point of fact, however, while the lower vocal range calls the vocal cords into vibration along their entire length, and while for the highest range only a portion of the edges of the vocal cords vibrate, the adjustment for the medium tones shows a gradual change from the first condition to the third. It is a bridge by which the voice crosses in safety from the lowest to the highest register--a register of transition, but a register withal.

Moreover, as the voice progresses upward through the scale, three distinct physical sensations are experienced by the singer according as to whether he is singing low, middle or high. There is one physical sensation for the lower, another for the middle and a third for the higher notes. This would indicate that there is, after all, more of a change in the adjustment of the vocal tract for the middle notes than is apparent superficially, and confirms the position of those who hold that there are three vocal registers instead of two.

In voice-production of the lower notes there is a physical sensation of vibration in the upper chest; on the medium notes, in the pharynx; on the higher notes, in the head. These physical sensations have determined the names of chest register for the lower and head register for the higher range of tones. Strictly speaking, the middle range should be denominated pharyngeal or throat register, but usually it is called the medium or middle register. In the chest register the vibrations of the vocal cords are slow and heavy; the vocal tract being in its relaxed, open adjustment, the larynx sinks slightly and, the vibrations taking place in their nearest proximity to the chest, they are communicated to it. In the middle register the adjustment of the vocal tract is more closed than in the chest register, the larynx rises a little, the shape of the vocal tract is determined largely by the relative positions a.s.sumed by the epiglottis and the soft palate, and the vibrations no longer can communicate themselves to the chest, but are felt in the pharynx. In the head register the vocal cords come together at one end, sometimes at both ends, and only the upturned edges of the resulting small aperture vibrate, throwing the sensation of vibration up into the head. In every way Nature seems to indicate that there are three vocal registers.

The most extreme limits of human voice so far known were found in the voices of Ludwig Fischer, a ba.s.s singer, and of Lucrezia Agujari (La b.a.s.t.a.r.della), a florid soprano. Fischer created the role of Osmin in Mozart's "_Entfuhring aus dem Serail_." His voice went down to contra F [Music: F1] an entire octave lower than the ordinary ba.s.s singer.

La b.a.s.t.a.r.della sang as high as [Music: C7] or an octave higher than what usually is spoken of as soprano "high C." These, however, were marvellous voices, so extraordinary that they form part of the history of singing.

Indeed, Baker, in his "Biographical Dictionary of Musicians," credits Fischer with D--a^1 [Music: D2-A4].

A reasonable statement of the vocal compa.s.s would be 2-1/2 octaves, or [Music: F3 to C6] for female voice and the same, an octave lower, for male voice. Allowing for unusual voices, the statement would be as follows:

[Music:

Treble staff: Low or Chest Register. D3-F4 Middle Register. G4-F5 High or Head Register. G5-F6

Ba.s.s staff: Low or Chest Register. C2-F3 Middle Register. G3-F4 High or Head Register. G4-C5]

This musical example shows that save for the lowest note of the ba.s.s voice and the three highest of the soprano, the male and female compa.s.s parallel each other at an interval of an octave apart, and that the division of the registers is the same for both.

Still utilizing the same musical example, but noting now the two chief divisions of male and female voices (ba.s.s and tenor in the male and alto and soprano in the female), the example would be divided as follows:

[Music:

Alto.

Low or Chest Register. D3-F4 Middle Register. G4-F5

Soprano.

Low or Chest Register. C4-F4 Middle Register. G4-F5 High or Head Register. G5-F6

Ba.s.s.

Low or Chest Register. C2-F3 Middle Register. G3-E4

Tenor.

Low or Chest Register. B[flat]2-F3 Middle Register. G3-F4 High or Head Register. G4-C5]

It must be borne in mind that registers overlap, that they extend up and down one into another, and that at points where this occurs it is optional with the singer in which of the two overlapping registers he will produce his tones. There are many singers who can sing at will the lower half of the middle register either in chest or middle, and the upper half of the middle either in middle or head. It is to be noted, however, that it is easier to bring down a tone from a higher into a lower register than to force up a register, the latter proceeding often being ruinous to the voice.

Duprez, a phenomenal tenor, could, as I have stated, sing the whole tenor range in the chest register. He could emit the _ut de poitrine_, which means that he could sing even tenor high C in the chest register.

The result was that half the tenors of Europe ruined their voices trying to imitate him. For they ignored the natural three-register divisions of the voice, and thought they could accomplish with their average voices what is reserved only for phenomenal ones.

There are three registers; and the interrelations between these and the different voices within the male and female range must now be considered.

CHAPTER VIII

SUBDIVISIONS OF THE VOICE

It should be remembered that in the old days, from which traditions of phenomenally high voices have come down to us, musical pitch was lower than it is now. In those days a tenor, for example, could carry up his voice in the adjustment for the middle or in phenomenal cases even for the chest register, instead of changing to the head register, more easily than can be done now. In fact, nowadays, when a composer calls for a very high note, it usually is transposed, so that actually the supposedly high C of _Di quella pira_ nearly always is a B flat.
