“Friendly Compression”

That’s the term I use for Manuel Garcia’s coup de glotte. The terminology and wording of Garcia’s theory of glottal closure caused a firestorm of controversy in the mid-to-late nineteenth century. The misunderstanding of it as a glottal plosive frightened many teachers, theorists, and voice doctors from that time to the present day.

Henry Holbrook Curtis derided it as “death to the voice”, and partnered with the De Reszkes, Jean and Edouard, to spread the terror of it throughout Europe. Of course, their versions, according to Blanche Marchesi, were highly exaggerated and not at all what Garcia intended.

Garcia’s wording on the exercising of the coup de glotte was ‘delicate’. It was a gentle closure of the glottis, not a ‘brutal pushing of breath’ ‘fit only to tear the glottis, not to rectify and regulate its movements.’

It is necessary to prepare the stroke of the glottis by closing it, which stops and momentarily accumulates some air in the passage; then, much as a rupture operates as a means of relaxation, one opens it with an incisive and vigorous stroke, similar to the action of the lips in pronouncing the consonant [p].

For author James Stark, the coup de glotte was a prephonatory setup of the instrument as well as a continuance of the tone in that particular firmer, ‘clamped’ (his word) arrangement.

Mathilde Marchesi is also in agreement with this idea as well when she wrote:

‘the glottis must be closed an instant before Expiration commences; in other words, it should be prepared’

From a breath management perspective, an efficiently adducted mechanism gives the tone a lower flow of air across the glottis. The result is that the singer needs less air for singing, not more. Numerous accounts of Old Italian School singers and authors speak of the fact that singers ‘scarcely breathed’. Visual perceptions of bodily breath were completely invisible. An effectively strengthened adductory mechanism would need less breath to bring the vocal cords into vibration.

You never saw her breathe – there was none of that heaving up and down. I remember thinking one evening during a performance, ‘I’m going to find out how she breathes.’ She as sitting on a bench and I had my arm around her – including a wine gum in my hand to give her when she got thirsty! – and I decided to feel how she did it. She just started singing – she went straight into it. And I thought, ‘She hasn’t taken a breath!’

Garcia’s coup de glotte is not only the onset, it is also the continuance of the tone with friendly firmness. This would lend credence to the wording of Jenny Lind (also a student of Garcia) who remarked that tones should be “struck” and “bound” together. This suggests she understood the idea behind the firm start of the sound, and the ensuing firmness of the tone. The pitch was ‘struck’ with the coup de glotte, then ‘bound’ to other tones in a phrase of music. For Garcia, a student was to exercise the coup in glotte in the first lesson, otherwise they hadn’t been taught properly.

…when singing, on one occasion, with Rubini, in the Matrimonio Segreto, he [Luigi Lablache] held the great Tenor’s hand in his own, during a passage in the famous duet, and, at the same time, looked him full in the face, without being able to detect the act of breathing in the least degree…triumph of consummate art.

In modern times, we recognize only three forms of onset: 1. soft, or aspirate, 2. hard, or glottal, and 3. balanced. None of these three forms of onset reflect Garcia’s ideas on the start of the tone. 

In my studio, I work with singers on ‘friendly compression’ through something I refer to as a ‘stingy hum’ with the mouth closed. It has the quality of a ‘squeaky door’ which must be done gently and with as little extrinsic muscle participation as possible – only the adductory muscles should be active and the throat relatively free and relaxed. The scale is usually some kind of gallop figure over the interval of a fifth, later expanded to the Rossini scale of an octave and a half.

Garcia wrote in Hints on Singing:

The lightness of movement is considerably facilitated if it be tried with the mouth shut. Once understood, it may be used with the mouth open on any vowel.

So that’s why I start all coup de glotte work with a closed mouth. The purpose is not to ‘blow breath’ against tightly adducted vocal cords. In fact, the maneuver can demonstrate to a singer the least amount of air needed to sing. From the Traité:

The rush of air, however, that is escaping through the half-open orifice, will be quite perceptible, and will give the sound a veiled character, at times extremely dull; this is frequently the case with the falsetto; we may hence conclude, that brilliancy of voice results from the entire closing of the glottis after each beat. Economy of the breath is another advantage derived from this complete closing of the glottis.

Some students refer to them as ‘vocal push ups’ because they build in a gentle way the adductory muscles of the larynx without ‘pressure of breath’. They are not user friendly, nor do I want students practicing them outside of lessons, where they will be likely to blow air against a tightly adducted mechanism. Students with whom I work in the exercise gain a true ‘ring’ of the voice, and an ease in register transition that is more efficient and less ‘pressured’. The ease with which high notes can be taken also attests to the effectiveness of firm glottal closure (without SQUEEZE, I might add).

The additional benefit of the exercise is awareness of shifts in the registration. If the mechanism is not allowed to adjust through the passaggio, a resultant tightness and strangulation of the throat will follow. This choke should not happen in any vocal exercise.  If the singer tries to ‘pull’ the lower register or mechanism up into the passaggio, this exercise will expose it right away.

To close, I’m going to include Garcia’s admonitions on the coup de glotte in his own Hints on Singing.

Christine Brewer on Breathing for Singing

I have learned to breathe for the phrase, let the texts inspire the breath, and release the breath right before the beginning of each phrase rather than holding it. I used to take a huge breath for every phrase whether I needed it or not. I learned that I needed to trust that my breath was going to carry me through each phrase.

Breath Management as a Compensatory Tension

In singing, the body gets the message to ‘help out’ when the cords lose their adducting strength. This appears to be a physiological law and the body kicks in to secure a firmer relation between itself and the throat. In any case, if, when we try to sing, the response from the voice is weak, it would seem natural to try to use a greater quantity of breath, in order to press our cords into action. This would then pose the questions not whether the extra breath is acceptable so much as ‘how much breath?’ and ‘how do we control it?’

Breath control is talked about as though the breathing apparatus must be manipulated. This is why ‘special breathing for singing’ has generally become of great importance in the eyes of singers and teachers. Unlike our vocal folds, breathing is by and large something that we can both feel and see. If a weak larynx ‘calls for support’ from the body – from the breathing department – it seems logical that the more breath we have the better, especially to support the voice through phrase after long phrase. It seems logical too that the stronger the engagement between the breath and the larynx, the louder and higher we will be able to sing.

[…]

The idea of ‘singing on the breath’ (as distinct from with the breath) possibly arose from the ease with which a voice in the ‘minimal breath’ condition flows, with its accompanying lack of pressure and absence of ‘fixing tension’. The implication is that the voice flows as the breath does, and while this may sometimes prove a helpful image, encouraging a more relaxed ‘delivery’, it does not necessarily bring about efficient vocalisation. A singer remains short of the mark so long as there is a real sensation that air is flowing. When the breathing apparatus is used wrongly we get the impression that breath is all-important, but when it plays its natural part without bidding, there is no such impression. The amount of air is infinitesimally small, as befits its delicate and highly specific task at the level of those tiny cords.

In singing it’s only when breath is evident, either in being dammed up or because it is ‘leaking’, that we should be concerned. To attempt to control the breath without the natural participation of the vocal folds is a folly, and the cause of much misplaced hard work, and damning struggle.

It would be convenient to be able to say that if breathing per se is ‘correct’ the voice will respond accordingly. Unfortunately, to function correctly in singing the breathing system needs the larynx and its extrinsic support system as much as the larynx needs the breathing system. ‘Breathing athletes’ with exemplary posture (such as yogis) may have their breathing very much under control but cannot sing.

Evan Williams Discussing Posture’s Relationship to Efficient Breathing

Singers study breathing as though they were trying to learn how to push out the voice or pull it out by suction. By standing in a sensible position with the chest high (but not forced up) the lung capacity of the average individual is quite surprising. A good position can be secured through the old Delsarte exercise which is as follows:

I. Stand on the balls of your feet, heels just touching the floor.

II. Hold your arms at your side in a relaxed condition.

III. Move your arms forward until they form an angle of forty-five degrees with the body. Press the palms down until the chest is up comfortably.

IV. Now let your arms drop back without letting your chest fall. Feel a sense of ease and freedom over the whole body. Breathe naturally and deeply.

In other words, to “poise” the breath, stand erect, at attention. Most people when called to this “attention ” posture stiffen themselves so that they are in a position of resistance. When I say attention,— I mean the position in which you have alertness but at the same time complete freedom, — when you can freely smile, sigh, scowl and sneer, — the attention that will permit expansion of the chest with every change of mood. Then, open the mouth without inhaling. Let the breath out for five seconds, close the mouth and inhale through the nostrils. I keep the fact that I breathe into the lungs through the nostrils before me all the time. Again open the mouth without allowing the air to pass in. Practice this until a comfortable stretch is felt in the flesh of the face, the top of the head, the back, the chest and the abdomen. If you stretch violently you will not experience this feeling.

Vennard on Breathing

Breathing per se is a dull subject, and even mastery of it will not insure good singing. Athletes frequently have enlarged their vital capacity to maximum, can hold their breath longer than most singers, and are are otherwise superior in this department, but still sing poorly. Also fine singers can be found whose technique is unorthodox, even poor. The important part is coordinating the breath pressure with the vibrator, which Louis Bachner called “hookup”. This is epitomized in the attack. A lesson on breathing should never consist of silent breathing exercises only. They should always be followed by practice in correct attack.
