Effective communication, whether you’re commanding a stage, weaving a story or pitching a big idea depend not only on your words, but on how you breathe.
Below, you’ll find an excerpt from my grandmother’s notebook, which, when seen through a contemporary lens, offers valuable lessons for present-day presenters and storytellers alike.
Notes on Breathing from the Notebook
Breathing is taking the air into the lungs and sending it out again.
Breathing Muscles
- The diaphragm is the most important because it is the largest single muscle and makes the most change in the size of the chest. It separates the chest from the abdomen, it is dome shaped and arches up into the chest.
- The inter costal muscles, between each pair of ribs in two layers with fibres running in opposite directions. The external inter costal muscles contract and swing the ribs outwards and at the same time the internal inter costals relax. When the ribs go back the reverse operation takes place.
- The abdominal muscles, they contract and control expiration.
- Scapular and clavicular muscles are also used.
The Method of Breathing for you Production
The Costal Diaphragmatic with Abdominal Control in Expiration (sometimes called the Whole Chest or the Central Method or Old Italian).
Air is taken in through the mouth (it is a bigger opening than the nostrils therefore more air can be taken in quickly and easily; nose breathing often leads to stiffness of the face giving a strained look and to noisy breathing.
When taking the breath in through the mouth the tongue and soft palate are in the proper position for producing tone but if air is taken through the nose they have to be readjusted. The air goes through the larynx and down the trachea which splits up into the right and left branchii each leading to a lung. These branchii split up into innumerable bronchial tubes, at the ends of each is a tiny air sac into which the air goes expanding the lungs. When air is taken in the ribs are swung out by means of the external inter costal muscles thus increasing the chest from side to side, at the same time the diaphragm contracts and flattens increasing the chest from top to bottom, the sternum is moved forward and because of this, the curve of the ribs, the chest is increased in size from back to front.
When the lungs are full the abdominal wall is gently drawn in pressing on the abdominal wall is gently drawn in pressing on the abdominal organs which in turn press on the diaphragm which returns to its natural arched position, thus squeezing enough air out for a phrase to be spoken.
While speaking the ribs are gently held out as long as the external inter costal remains contracted.
Bad Methods of Breathing
- The clavicular or collar bone method. In this method the shoulders are raised in taking the breath in and the abdominal wall is often drawn in. This method is bad because the upper part of the chest is used. It is very tiring and ugly and the great fault with this method is expiration cannot be easily controlled. It sometimes leads to stiffness of the upper part of the chest which is sometimes communicated to the throat and stiffness in any part of the vocal mechanism is bad for the tone.
- The abdominal method. In this method the diaphragm is pressed down on the abdominal organs which in turn cause the front abdominal wall to protrude. Expiration cannot be so well controlled as by the costal diaphragmatic and it is ugly.
Contrast Between Breathing of Repose (or Natural) and Breathing for Voice Production
Breathing of Voice Production
- Voluntary and controlled by the subconscious mind
- Full capacity of chest used
- The amount of air taken in varies with the phrase spoken and there is no pause after expiration
Tranquil Breathing
- Involuntary and uncontrolled
- Full capacity of chest not used
- Regular amount of air taken in, slight pause after expiration
Faults in Breathing
- Breathing Tone: This is caused by taking in more air than the muscles are able to control so some air escapes unvocalised and we get breath mixed with the voice. The air is expelled before the vocal cords meet. To cure this the muscles must be strengthened, ie. The diaphragm and inter costal muscles. Take in air but do not overcrowds the lungs and say a short phrase trying to keep the ribs out and listening carefully that all the breath is turned into tone, as the power grows increase the length of the phrase.
- Gasping: This is caused by saying too much in one breath. The speaker hurries on regardless of pauses, uses up all their surplus breath and begins to call on their residual breath and gasping follows. In beginners it is sometimes caused through nervousness. Proper phrasing and care and steadiness are the cure.
- A Click before Tone: This is caused by poor control of the breath again. The cords meet before the breath is ready to pass through and a click follows. Proper timing of the abdominal press is the cure.
- Rebound: This is adding a vowel sound after the final consonant of a word, as un-der due to letting too much air escape with the last sound. Care should be taken not to let fresh air escape with the last sound.
- Tremolo: This is like the vibrato in singing an is caused by unsteadiness of the muscles. It can be remedied by attending to breath control. Speaking above or below one’s compass will sometimes cause it.
- Noisy Breathing: This is sometimes due to adenoids or enlarged tonsils, these require medical attention. If there is no organic defect it is through carelessness and stiffening of the mouth and soft palate. At first take the breath in slowly and silently and the more quickly as one improves.

Modern Insights: Bringing Breathing Techniques into the 21st Century
Today experts in vocal performance, mindfulness and even sports science universally acknowledge (see further reading for articles) the value of deliberate breathing. The costal diaphragmatic method, as described above, remains central to performance technique but now we better understand its role in stress reduction, stamina and vocal clarity.
- Mindful breathing is proven to lower anxiety before speaking, enhancing confidence and focus.
- Nose breathing is preferred in general health to filter and humidify air, but for vocal projection, mouth breathing is effective when done consciously with relaxed facial muscles.
- Apps and devices can now help speakers track and train their breathing, while modern trainers emphasise relaxation as much as control.
- Warm-up routines for presenters often include breath exercises, stretching and even short meditation to prime both body and mind.
- Understanding your own “breathing faults” helps tailor practice, video and audio feedback help track progress.
Blending this wisdom of past and present empowers presenters and storytellers to use breath as a foundation for authenticity and impact to as a key to unlocking their best voice.
