About qi and degree.
Breath control: the pronunciation, sound level, strength, length and rigidity of the flute are closely related to the "luck" when playing. This kind of luck kung fu is called "Qigong", which means that if you want to play the flute well, you must work hard on "luck".
In our daily life, we exhale and inhale for roughly the same time. When playing the flute, you need to take a deep breath, that is, use the diaphragm (located between the lungs and abdomen) to exert force, that is, chest-abdomen combined breathing. It is best to use your mouth and nose when breathing. Give priority to with the mouth, that is, let go of the corners of the mouth and inhale slightly, so that inhalation is faster. When exhaling, you should use the control ability of chest muscle, abdominal muscle and diaphragm to make the breath spit out evenly and rhythmically. Beginners should consciously pay attention to the breathing method from the beginning, and don't violate the movement law of normal breathing, otherwise it will affect the performance and be detrimental to their health. It is not bad for a novice to spit 10- 15 seconds in one breath.
Luck is very important to players. It is the basis of beautifying timbre, controlling timbre strength and various emotional changes. In order to master the correct method of "luck", you can do the following two exercises in combination with playing long notes:
Breathe slowly, breathe slowly-take a deep breath and blow a long sound. When inhaling, it is required to inhale enough without making any noise, and when exhaling, it is required to be uniform and stable for a long time without effort. So don't finish breathing when you exhale (about one fifth is left, and the diaphragm of the lower abdomen is still under control). That is, the second breath needs to be inhaled. Make sure that the movements of the chest and diaphragm abdomen are always consistent, otherwise the airflow entering the mouthpiece will not be smooth, and it is prone to air leakage, screaming and unpleasant timbre at the corners of the mouth.
Breathe fast and breathe slowly-this is the most commonly used breathing method when playing bamboo flute. The shorter the inhalation time, the better, because the time allowed for inhalation during music is very short.
(2) Some misunderstandings about breathing luck should be avoided:
1 shrug. When inhaling, lift your shoulders up, so your breathing is shallow and you can only inhale into your chest. Inhale like this and tighten your chest. When playing, the lack of strong support of breath not only makes the tone tense, but also makes the long sound unsustainable.
2 abdomen. When inhaling, the lower abdomen will be mistakenly forced to contract inward. In this way, the breath can only be sucked into the upper chest, causing the pectoral muscles to press the ribs tightly, making the breathing inelastic.
3 stand up. When inhaling, the abdomen bulges out and the abdominal ribs are pulled down. Because the breath is inhaled too deeply, the muscles in the chest and abdomen are tense, which makes the breathing inelastic.
Therefore, to play the flute well, we must master the correct breathing method and luck.
