Understanding a few concepts can bring you closer to what you should do.
1. The essence of breath is not how much lung capacity there is, not a large amount of output gas, but the maintenance of breath, or the maintenance of air pressure. Simply inhaling too much will make your respiratory muscles and larynx tense before you make a sound, which will affect your vocalization.
A large amount of output air will first bring disaster to the closure of the vocal cords and the stability of the larynx, that is, excessive air leakage in the vocalization.
The appropriate amount of inhalation and maintain a stable air pressure is given according to the amount of breath that is automatically required when the vocal cords make a sound, or you can just make a sound without thinking about the amount of exhalation. As long as you do it (with the right amount of breath and a steady air pressure), that's the foundation of support.
2. Further understand the concept of waist and abdomen, which is not just a so-called orientation, but an important detail related to the control of breath and the maintenance of air pressure.
In fact, the correct use of respiratory muscle groups is something that everyone knows, but it is easy to be overlooked.
Let's take a closer look at how to use the lumbar and abdominal respiratory muscles, which are the state of the lower back and abdomen when a child or adult is crying or sobbing, and the respiratory muscles near the lower back and abdomen are mobilized.
Maintain a state that is not forced, but actively work, air pressure maintenance, breath use, vocal cord vibration, etc. will enter a good cycle in overall coordination, and crying or sobbing for a long time will not get tired (except for active fake crying to attract attention).
In fact, the dog panting demonstrated by Lin Junjie, if you have practiced correctly, and in the process of maintaining, you will feel that when the breath is used, the muscle groups and the feeling of exertion will be relatively to the waist and abdomen, to the back, and to the waist, and you will also experience the so-called "sigh", "lean" and "support" The breath support feeling, the vocalization is very easy, smooth, and throat-saving.
When you were a child, if you had a prank, making a sharp voice similar to a wicked laugh, sneer, witch, wizard, you will also experience, and you will find that it is easy to use some necessary muscles and fascia in the lower back, abdomen, and even shoulders and neck, in fact, when the singer sings to a certain long note and pitch, the physical state is very similar.
I won't describe the specific feeling of force, it is recommended to experience and practice, and you will find your approximate feeling, so as to strengthen the overall coordination and use of respiratory muscles, and then make the texture and three-dimensional sense of sound go further.
3. "Piston" to understand the relationship between the diaphragm and the main respiratory muscles of the waist and abdomen, as well as the breath in the lungs. For example, the relationship between the state of the diaphragm and the breath in the lungs is the simplest, when the diaphragm descends, the breath in the lungs is relatively full.
When the diaphragm relaxes, there is a large loss of breath and air pressure in the lungs. And what is the relationship between breath, air pressure, sound fullness, and vocal cord closure? Thinking about this, you can understand it by taking balloons and tires in life.
But the diaphragm is definitely not staring at it alone, when using it, how to say, you will find that the whole body such as the buttocks, waist and abdomen, abdomen, shoulders, neck, etc. will be coordinated as a whole, and you will feel the lower back and back will also be mobilized.
Instead of feeling, the strength is only in the waist, or feeling a lot of strength and stiffness piling up near the neck, throat, jaw.
Let's experience it in sneering, laughing, dog panting, and continuous strange barking, and slowly combine this kind of experience into the vocalization, and the breath control will really get started, and it will make the voice greatly improved.
