1, to form a good mouth shape, we must first keep the neck, throat and mouth relaxed naturally, the lips naturally stick to the teeth, and the upper lip is slightly forward. Then, pinch your mouth and make an "H" sound (vocal cords don't vibrate), so that the throat cavity and oral cavity naturally relax and open (containing air), and the muscles of cheeks, corners of the mouth and upper and lower lips naturally gather in the middle, which directly promotes the formation of an oval "air door" (feeling like a circle) between the upper and lower lips.

2. Then, the middle part of the lower lip is slightly aligned with the blowhole, covering the blowhole of about14, and the exhaled breath is injected downward into the blowhole through the "valve", which acts on the flute pronunciation.

3. After defining the basic shape of the mouth shape, we should also pay attention to the angle between the mouth shape and the blowing hole, so that the lips and the blowing hole form a 90-degree right angle, the breath is unimpeded, the flute is full, the air leakage is minimized, and efforts are made to make the flute sound pure and round. In the practice of mouth shape formation, we should always pay attention to keeping the throat, mouth and tongue relaxed naturally, and play the mouth shape constantly under the guidance of "H" sound.

Breathing practice of flute

1, suction

Breathe quickly, then blow slowly. Ten times a day, remember to concentrate the air in the vibrating tube of chest cavity, throat cavity and oropharynx cavity. It is also good for muscle training of vibrating tube.

2, rapid suction and vomiting, diaphragm group exercise

Maintaining a good voice requires a strong control over the diaphragm. Therefore, it is necessary to constantly practice the stretching and bouncing ability of the diaphragm group, as well as the strong control of sound intensity and high and low breathing. The better method is: from slow to fast, from weak to strong, from fast to fast, starting from the nose and mouth while practicing, and observing the dog's open understanding of asthma in summer; Keep practicing, this method will have great effect.
