We use normal breathing (abdominal breathing or thoracoabdominal breathing) to blow, and when we finish blowing in one breath, the sound should be disconnected, because we have to inhale, and inhalation cannot be blown. By circulating ventilation, the sound can be played continuously, because it can be played while inhaling, that is, when inhaling through the nose, the air in the mouth can be blown out-this is not the air coming out of the lungs, but the air stored in the mouth is squeezed out-the action of pinching the cheek and the movement of the tongue from back to front will squeeze out the air in the mouth. The sequence of cyclic ventilation: from 1 to 2 to 3 to 4 is a complete process.
1 means "normal exhalation in the mouth", and 2 means "gas in the mouth"
3 means "holding your cheeks, inhaling through your nose and exhaling", and 4 means "receiving air"
The following are the specific practice steps of learning cyclic ventilation: don't practice on playing musical instruments yet, just practice on the air.
First of all, practice "pinching your cheeks and exhaling while inhaling through your nose".
1, flaring can store a certain volume of gas, such as bulging cheeks. However, there is no requirement to drum cheeks too much, just drum cheeks properly. It is necessary to expand the oral cavity from both horizontal and vertical aspects. Lateral expansion of the mouth can be accomplished by bulging the cheeks; The vertical expansion of the oral cavity can be achieved by making "ou" sound or "I" sound (but not making sound), that is, the mouth and jaw move downward.
2, stop the normal exhalation, and squeeze the exhalation inward, actually squeezing the gas out of the mouth. This action can be practiced alone.
3. Practice inhaling quickly from the nose to the abdomen (the abdomen should expand outward). This action can be practiced alone. 4. Practice "pinching your cheeks and exhaling and inhaling through your nose". These two actions are carried out at the same time. I was not used to it at first, because I couldn't use two things at the same time. But you will get used to it after a few days of practice. Summary:
1, the completion time of nasal inhalation should be less than the completion time of cheek-pinching exhalation. If the time for pinching the cheek and exhaling is 4 seconds, then the time for inhaling the nose is 1 to 2 seconds.
2. When you are a beginner, you don't have to squeeze your cheeks. After getting used to it, pinch your cheeks a little harder. 3, nasal inhalation should not be too fast, nor too slow, nasal inhalation should try not to make inhalation sound, a little sound is normal.
Second, practice "exhaling normally from mouth to expanding oral gas storage".
Breathe out normally in the mouth (that is, exhale normally), and then make a transition to expand the gas storage in the mouth. During this process, the normal exhalation of the mouth has been maintained.
Third, after the above two steps are successfully practiced, you can start practicing the whole process of circulating ventilation. Or not yet.
Practice on the wind instrument, you can practice on the air.
Let's practice the whole process of circulating ventilation with an empty mouth: step one, "breathe normally with your mouth" (through abdominal or thoracoabdominal breathing)
The second step is "oral gas storage" (keep the normal exhalation in the first step, expand the oral volume, and the exhalation can't stop)
Step 3: "Pinch your cheeks and exhale through your mouth, and inhale through your nose at the same time" (the previous step stops exhaling, and you turn to pinch your cheeks and exhale through your mouth, while your nose quickly inhales into your abdomen. Don't inhale too much, just right)
Step 4: "Inhale" (half or more than one third of the air in the mouth is not squeezed out, continue to squeeze the cheek to exhale, and at the same time slowly exhale the air sucked into the abdomen in the previous step and breathe with the air generated by squeezing the cheek)
Many people use straws to blow into a glass of water. It's ok if bubbles can be generated continuously. ) learn to practice cyclic ventilation on playing musical instruments;
You can practice on playing musical instruments when you practice circular ventilation.
Matters needing attention and main points:
1, "Exhale with your cheeks and inhale through your nose" is the key. You should practice more and practice alone. The process of inhaling through the nose is shorter than that of pinching the cheek.
2. Don't wait until the last breath is almost over before you start cycling. When you exhale half or two thirds of your last breath, you will start the next ventilation cycle.
3. Breathing is a difficulty. To make a smooth transition (also called a soft landing), don't turn the volume up and down. Of course, this requires long-term practice.
4, beginners cycle ventilation (cycle breathing) If you feel uncomfortable, such as chest tightness, breath holding, etc. You should stop at once, have a rest and practice again.
5. When walking, cycling, watching TV, etc. , you can practice circulating ventilation in the air. 6. Learn to circulate ventilation with the foundation of abdominal and chest-abdominal breathing.
7. Have confidence in learning, and don't think that circulating ventilation is too difficult and mysterious. Anyone can learn.
