Why do children's vocal music teaching methods advocate abdominal breathing singing?

Many people talk about breathing, and the key is to adjust the usage of breathing according to the specific conditions and conditions of students. I prefer abdominal breathing to these breathing methods. Chest breathing has some sounds and movements, and the breath is too shallow; Thoracoabdominal combined breathing is a little higher than abdominal breathing, and it also has some shortcomings. Abdominal breathing, relatively speaking, is deeper. From the teaching point of view, that is to say, it eventually becomes lower and the breath eventually becomes deeper.

Traditionally, it is called dantianqi. The abdomen is two inches below the navel. In fact, from the perspective of breathing, all breathing is lung breathing. It is impossible to inhale the lower abdomen, but you have to feel it enter the abdomen through physical and mental cooperation. Just like the concept of qigong, you have to put it down. There are some similarities between our vocal music teaching and Qigong, and there is also a problem of feeling, metaphor and hypothesis. When you feel that you are sucked in there, it is actually equivalent to letting go of your breath.

The advantages of this kind of abdominal breathing are: first, the action is not obvious when inhaling; Second, there is no sound, the breath is calm, and it is sucked into the depths; Third, breathing is faster, sometimes singing fast songs. Steal a breath in the middle, as long as you relax, the breath will be sucked in and others will not see it. So I advocate singing with abdominal breathing, which makes the singing sound fuller.
