Each of us is born with the innate ability to breathe. A perfect breathing, able to be the most energy efficient, maximum results with minimum effort. Then at 3/6 years, when our mind starts to become more relational and less instinctive, the brain begins to take over and implement unconscious processes that dominate the natural ones, but they almost always are less efficient.
At that age, you subconsciously stop having posture and natural breathing in order to switch to more rigid and contracted forms. In fact, at that time, we find that stiffening posture and the diaphragm, not surprisingly also called emotional muscle, diminishes the perception of emotions and fears on a visceral level.
The more a children have a fear of their inner feelings, without someone explaining to them that this is absolutely normal, and the more of their vocal expressiveness will be sacrificed in order to no longer hear more of these bad feelings.
I hear all too often breathing being spoken about in terms that are absurd, sometimes I find people are convinced that the diaphragm is a voluntary muscle and that it is even able to make sound!
Breathing is at the base of the voice. The voice comes with breathing. We often hear people talk about "throaty voice" or "diaphragmatic voice," but in reality the voice is always produced by vocal apparatus and supported by the air flow produced by the diaphragm.
It is easy to identify the vocal apparatus: it is what you feel moving every time you swallow. recognizing the diaphragm is not equally simple: It is not able to produce any sound and is located inside the torso to divide the lungs from the bowels.
When it comes to human beings, the amount of air available to it is almost never a problem, but its management and the pressure that supports the vibration of the vocal cords can be. The secret of a good vocals is all about knowing how to measure and direct the air that sustains the words we speak. Depending on the errors in the quantity of air or in the stronger or weaker adduction of the vocal chords, all the possible existing phonation defects are configured, sometimes erroneously considered as "virtues" by unscrupulous people.
