The cyclic ventilation of the flute includes the long-tone cyclic ventilation and the double-spit circulatory ventilation method. These two kinds of circulating ventilation methods are the difficult skills that flute players talk about, because they are more difficult and have performance requirements. Circulation ventilation is often used in longer pieces of music, just to make it easier for flutists to play the flute, and circulation ventilation also came into being. The long-tone cyclic ventilation method was created by the master of the Zhejiang school, Master Zhao Songting. At that time, it was transplanted from the suona instrument in the 1950s and applied to the solo of flute music. Among them are the classic flute tunes "Partridge Flying" and "You Orchid Meets Spring", which are also grade-10 test pieces.

In addition to the long-tone cyclic ventilation method, there is also the double spit circulatory ventilation method. The double spit circulatory ventilation method has two performance methods. In fact, it is the fast breathing method of the new bamboo flute, and it is also a breathing technique obtained in practice. The representative works of double-spitting cyclic ventilation flute pieces include "Infinite Movement" and "Oasis". By learning these two flute pieces, you can basically master the skills of double-spitting circulatory ventilation and apply them to flute pieces. Double spit circulatory ventilation is more difficult than long-tone circulatory ventilation, because its pronunciation is a sound that does not need to be spit. Everyone knows that double spit sound, it must have two sounds of "spit library". How can the double spit cycle ventilation be done without spitting?

In fact, it's very simple, you just need to change the original pronunciation "Tuku" into "Puku", and use the lingering breath of the lower jaw to press and punch out, so that the lips reach a touch-open tone. At the same time, when the word "Pu" is pronounced, the nose inhales and changes quickly, and then the music is played naturally, so that the sound of the flute will not stop or break. In fact, this kind of pronunciation changing the concept of stealing ventilation is the front tone ventilation method. "Tuku" has two pronunciations. Similarly, if you put the pronunciation position on the word "ku" to return your breath, this is the back-sound ventilation method. It uses the lower jaw to punch out a "tiger" character, which can be played by changing the sound shape.

After using these two tips of double spit cycle ventilation, you can switch freely after a period of time. It can eventually be used for playing music, even if it is successfully mastered. Both of these ventilation methods use the air stored in the lower jaw (larynx), and the flute is played first. When the mouth shape makes "Pu" and "Tiger", it is necessary to practice single blowing alone, combined with etudes. The sound should be sounded, the qi should be strong and strong, and the two sounds should be strong. It should be noted that it is not using the qi of the dantian. Instead, it relies on the linking effect of a breath in the chest and abdomen, which is punched out by the continuous air of the lower jaw.

Only by blowing the two tones of "Pu" and "Tiger" out of the "Tuku" effect, can you master the cyclic double-spitting ventilation skills, and then you only need to practice your tongue flexibly. Combining the two sounds, for example, deliberately playing "Tuku" to "Puku" and "Tuhu", and using the inertia of the tongue, the sounds of "Tu" and "Ku" are issued from the root of the tongue. At the same time, take a breath on the words "Pu" and "Tiger", and practice in a cycle. Remember that you must be used to grabbing a breath with the nose. The difficulty of the double-spitting cycle is difficult for many people.

Of course, no one knows this skill at the beginning, and later on, it starts with gradual progress. If not, you can practice for a period of time in combination with the circular double-spitting flute tune "Infinite Movement", and slowly you can experience the little skills of double-spitting circular ventilation.
