BREATHING AND BREATH-CONTROL

It is generally considered that, as the breath is the foundation of singing, the manner of breathing is of vital importance to the singer. This subject has therefore received a vast amount of attention from vocal scientists, and the muscular actions of breathing have been exhaustively studied.

Several sets of rules for inspiration and expiration are put forth by different authorities. But there is no occasion for going into a detailed discussion of the different modes of breathing advocated by the various schools, or of the theoretical arguments which each advances. It is sufficient to say that the modes of breathing most in vogue are five in number,—deep abdominal, lateral or costal, fixed high chest, clavicular, and diaphragmatic-abdominal. However, on experimenting with these five systems of breathing, it is found that the number may be reduced to two; of these the others are but slight modifications. In one system of inspiration the abdomen is protruded, while the upper chest is held firm, the greatest expansion being at the base of the lungs. In the other mode of taking breath the abdomen is slightly drawn in, while the chest is expanded in every direction, upward, laterally, forward, and backwards. In this system the upper chest is held in a fixed and high position.

Necessarily the manner of filling the lungs involves the manner in which they are emptied. Opinions are practically unanimous as to the proper position of the singer before taking breath, that is, at the end of an expiration. The singer must stand erect, the weight of the body evenly supported on the balls of both feet, with the whole body in a condition of lithe suppleness. In both systems of breathing the manner of expiration is simply a return to this position.

A wide variety of breathing exercises are in use, but these do not require detailed description. Any one of the prescribed systems of breathing can easily be adopted, and the student of singing seldom encounters any difficulty on this point. Still most teachers attach great importance to the acquirement of the correct manner of breathing. Toneless mechanical exercises are generally given, by which the student is expected to master the muscular movements before applying in singing the system advocated by the teacher. These exercises are usually combined with those for breath-control, and they are described under that head.

Breath-Control

Very early in the development of Vocal Science the management of the breath began to receive attention. Mannstein,[2] writing in 1834, says: “The air in expiration must stream from the chest slowly and without shock. The air must flow from the chest with the tone.” In a footnote he adds: “In order to acquire this economy of the breath, students were required to practise daily, without singing, to take and to hold back the breath as long as possible.” Manstein does not mention the muscular action involved in this exercise.

This subject is also touched upon by Garcia. In the first edition of his École de Garcia, 1847, Chap. IV, p. 14, he says: “The mechanism of expiration consists of a gentle pressure on the lungs charged with air, operated by the thorax and the diaphragm. The shock of the chest, the sudden falling of the ribs, and the quick relaxing of the diaphragm cause the air to escape instantly…. If, while the lungs are filled with air, the ribs are allowed to fall, and the diaphragm to rise, the lungs instantly give up the inspired air, like a pressed sponge. It is necessary therefore to allow the ribs to fall and the diaphragm to relax only so much as is required to sustain the tones.” It may be questioned whether Garcia had in mind the doctrine of breath-control as this is understood to-day. Very little attention was paid, at any rate, in the vocal instruction of that day, to the mechanical actions of breath-control; the great majority of teachers probably had never heard of this principle.

As a definite principle of Vocal Science, breath-control was first formulated by Dr. Mandl, in his Die Gesundheitslehre der Stimme, Brunswick, 1876. From that time on, this doctrine has been very generally recognized as the fundamental principle of correct singing. Practically every scientific writer on the voice since then states breath-control as one of the basic principles of Vocal Science. The most influential published work in popularizing the doctrine of breath-control was probably the book written jointly by Lennox Browne and Emil Behnke, Voice, Song, and Speech, London, 1883.

This doctrine is of so much importance in Vocal Science and in modern methods of instruction as to require a detailed explanation. The theory of breath-control may be stated as follows

“In ordinary breathing the air is expelled from the lungs quietly, but rapidly; at no point of the breathing apparatus does the expired breath meet with resistance. In singing, on the contrary, the expiratory pressure is much more powerful, yet the expiration must be much slower. Furthermore, all the expired breath must be converted into tone, and the singer must have perfect control over the strength and the speed of the expiration. This requires that the air be held back at some point. The action of holding back the breath must not be performed by the muscles which close the glottis, for all the muscles of the larynx are very small and weak in comparison with the powerful muscles of expiration. The glottis-closing muscles are too weak to oppose their action to the force of a powerful expiration. If the vocal cords are called upon to withstand a strong breath pressure, they are seriously strained, and their proper action is rendered impossible. In the same way, if the throat be narrowed at any point above the larynx, so as to present a passage small enough to hold back a powerful expiration, the entire vocal mechanism is strained and forced out of its proper adjustment. The singer must have perfect control of the breath, and at the same time relieve the larynx and throat of all pressure and strain. To obtain this control the singer must govern the expiration by means of the muscles of inspiration. When the lungs are filled the inspiratory muscles are not to be relaxed as in ordinary breathing, but are to be held on tension throughout the action of expiration. Whatever pressure is exerted by the expiratory muscles must be almost counterbalanced by the opposed action of the muscles of inspiration. The more powerful the blast, the greater must be the exertion by which it is controlled. In this way, the singer may have perfect control both of the speed and of the strength of the expiration.”

[Note 3: This statement of the doctrine of breath-control must not be construed as an endorsement of the theory of the vocal action embodied in this doctrine. On the contrary, both the theory of “opposed action” breath-control and the “breath-band” theory are held to be utterly erroneous.]

The exercises for acquiring a command of this “opposed action breath-control” are easily understood; indeed, they will readily suggest themselves to one who has grasped their purpose. Most important of these exercises is a quick inspiration, followed by a slow and controlled expiration. Exercises for breathing and breath control are usually combined; the student is instructed to take a breath in the manner advocated by the teacher, and then to control the expiration.

Teachers usually require their pupils to obtain command of this action as a toneless exercise before permitting them to apply it to the production of tone. Methods vary greatly as to the length of time devoted to toneless drills in breathing and breath control. Many teachers demand that students practise these exercises daily throughout the entire course of study, and even recommend that this practice be continued throughout the singer’s active life.

Simple as these exercises are in theory, they demand very arduous practice. Control of the breath by “opposed action” is hard and tiring muscular work, as the reader may easily convince himself by practising the above-described exercise for a few minutes.

No special rules are needed for applying this model of breathing to the production of tone. Theoretical writers generally do not claim that the control of the breath brings about the correct laryngeal action, but merely that it permits this action by noninterference. Several authorities, however, notably Shakespeare, maintain that in effect this system of breath-control embodies the old precept, “Sing on the breath.”Other theorists hold that the empirical precept, “Support the tone,” refers to this manner of controlled expiration.

The “Breath-band” System

While most authorities on the voice advocate the system of breath-control by “opposed muscular action,” there are a number of masters who teach an entirely different system. This is usually known as the “Breath-band,” or “Ventricular” breath-control. Charles Lunn, in The Philosophy of the Voice, 1878, was the first to propound the theory that the breath may be controlled by the false vocal cords. There is reason to believe that this idea was also worked out independently by Orlando Steed . As a number of prominent teachers base their entire methods on this theory, it is worthy of careful attention. The “breath-band” theory may be stated as follows:

“When the lungs are filled by a deep inspiration and the breath is held, the glottis is of necessity closed so tightly that no air can escape. In this condition, the expiratory muscles may be very violently contracted, and still no air will escape; indeed, the greater the strength exerted the tighter is the closure of the glottis. Obviously, this closure of the glottis cannot be effected by the contraction of the glottis closing muscles, strictly speaking, for these muscles are too small and weak to withstand the powerful air pressure exerted against the vocal cords.[4] The point of resistance is located just above the vocal cords. The sudden air pressure exerted on the interior walls of the larynx by the expiratory contraction causes the ventricles of the larynx to expand by inflation. This inflation of the ventricles brings their upper margins, formed by the false vocal cords, into contact. Thus the opening from the larynx into the pharynx is closed. This closure is not effected by any muscular contraction, therefore it is not dependent on the strength of the muscular fibres of the false vocal cords. It is an automatic valvular action, directly under voluntary control so far as the contraction of the expiratory muscles is concerned, but independent of volition as regards the action of the false vocal cords. On account of their important function in this operation, the false vocal cords are called the ‘breath-bands.’ Closure of the glottis by the inflation of the ventricles imposes no strain on the vocal cords.

[Note 4: One of the strongest arguments of the “breath-band” advocates is based on this action,—the resistance of the closed glottis to a powerful expiratory pressure. The theory of breath-control by “opposed muscular action” takes no cognizance of this operation. The “breath-band” theorists are mistaken in asserting that the action of holding the breath is not performed by the glottis closing muscles.]

“Control of the breath in singing is affected by this automatic valvular action. To produce a tone according to this system, the lungs must be filled and the breath held in the manner just described, while the vocal cords are brought to the proper degree of tension; then the tone is started by allowing the ‘breath-bands’ to separate very slightly, so that a thin stream of air is forced through the opening between their margins. The tone is ushered in by a slight explosive sound, which is nothing but the well-known stroke of the glottis. So long as the expiratory pressure is steadily maintained, this tone may be held, and yet no strain is imposed on the vocal cords. Perfect control of the breath is thus attained. For a powerful tone, the breath blast is greater, therefore the ventricles are more widely inflated, and the opening between the ‘breath-bands’ becomes narrower. The action is always automatic; once the tone is correctly started, the singer need pay no further attention to the operation of the ‘breath-bands.’ All that is necessary is to maintain a steady breath pressure.”

In the methods of all the “breath-band” advocates, the first and most important step toward perfect tone-production is held to be the acquirement of this automatic breath-control. As in the “opposed muscular” system, the initial exercises are toneless drills in breathing. The basic exercise, of which all the others are variations, is as follows: “Fill the lungs, then hold the breath an instant, and forcibly contract all the chest muscles. Then force the air out slowly and powerfully through the glottis.” Practice of this exercise is always accompanied by a hissing sound, caused by the escape of the air through the narrow slit between (presumably) the “breath-bands.” Tone-production by the same muscular action is very simpl and requires no further explanation.

In its practical aspect, this system of breath-control is the direct opposite of the “opposed muscular” system. In one the breath is expelled powerfully, the object is to bring a strong expiratory pressure to bear on the larynx. In the other system, the air is held back, in order that the larynx be exposed to as light a pressure as possible.

The “breath-band” advocates hold that the glottic stroke is the key to correct laryngeal action. As a rule they instruct their pupils to attack every tone, throughout all their practising, with the stroke of the glottis. In the course of time the automatic valvular action is supposed to become so well established that the singer can dispense with the glottic stroke in public performance. Needless to say, these teachers usually recognize that this explosive sound is very harsh and unmusical, and utterly out of place in artistic singing.

An important claim of the “breath-band” teachers is that their doctrine contains the explanation of the traditional precept, “Support the tone.” Their idea is that the throat, being “firmly set,” furnishes a secure base for the tone to rest on. This explanation is of course utterly unscientific, and it cannot be said to throw any light on the meaning of the precept. “Singing on the breath” is also referred to this system of breath-control, but with no more coherence than the “Support of the tone.”

No necessary connection obtains between systems of breath-control and those of breathing, strictly speaking, that is, of inspiration. As has been said, the great majority of vocal theorists adhere to the “opposed muscular action” breath-control. In this number are included advocates of every known system of breathing. Bitter controversies have been carried on between champions of different modes of breathing, who yet agree that the breath must be controlled by “opposed action.” This is also true, although not to the same extent, among the “breath-band” teachers. And to render the confusion on the subject of breathing and breath control complete, instances might be cited of controversies between teachers who agree as to the correct mode of inspiration and yet disagree on the manner of controlling the expiration.

Both systems of breath-control cannot be right; if one is correct, the other must necessarily be absolutely wrong. Instead of attempting to decide between them, it will be seen that both are false, and that the theory on which they rest is erroneous. This discussion is reserved for a later chapter.
