The "double spit" of cucurbit flute is the most important of all techniques, because most of the intermediate and advanced tunes have the double spit technique. Silk tunes cannot be played.

Double spit is an important and difficult technique for cucurbit playing. If you don't know the double vomit technique, you can basically only play the cucurbit flute below the fourth level, because the tunes above the fifth level basically need to use the double vomit, and the higher the level, the more double vomit. The way for many cucurbit flute lovers to learn is blocked on double spit.

Although double vomiting is a bit difficult to learn, hasn't everyone learned it? !

The difference between single spit and double spit: single spit, the tongue is stretched out to pronounce; double spit is the pronunciation of both tongue out and retraction. Therefore, the sound of the sixteenth note can be played with double spit (depending on whether there is a requirement for double spit or triple spit on the score, the double spit symbol on the score is "TK").

There are several ways to blow (pronounce) double spit:

The first type: spit bitterness (or make a "spit library" sound). This is what most people think so. 

The second type: TK (English alphabetic sound, like "Turk")

The third type: mumble

Learning to vomit must follow the law of "quantitative change to qualitative change". Only by practicing more can you find the feeling and the day you suddenly learn it.

The following are the learning methods and steps of double vomit:

First: don't practice on the cucurbit silk first, practice with an empty mouth first.

"Tu" and "ku" are practiced separately, such as "Tu Tu Tu...", "Ku Ku Ku...". The sound should be short and powerful. Don't go too fast. Don't strain your throat.

Practice the "bitter" sound more. To practice bitterness, you should exaggerate and use force. You can place your palm (palm facing your mouth) in front of your mouth, make a bitter sound, and feel with your palm whether the "bitter" qi is powerful.

Second: empty practice "spit spit bitter, spit spit bitter,..." and "spit bitter spit, spit bitter spit,..." Practice slowly at first, and then speed up a little bit when the mouth is smooth.

Third: empty practice "spit bitterness, bitterness, bitterness, bitterness,..."

Fourth: empty practice "spit bitterness and bitterness..."

After the above part of the mouth is smooth, the mouth and tongue are no longer sour (that is, the mouth and tongue are strong, this process may take two weeks or a month, each person is different, some one week is enough), you can reach the cucurbit silk Go up and get a feel for it.

Fifth: practice double spit (or triple spit) on cucurbit silk.

Personally, I think it's easier to find the feeling by blowing "spit out bitterness, spit out bitterness, ..." a little faster first.

First of all, what kind of cucurbit flute should I learn to practice double vomit? If you turn off the practice with a pipe, you can

B, A, major G, cucurbit silk on the practice. If you let go of the attached tube, you can learn and practice in the minor D key. After learning, turn off the attached pipe and practice the graininess of double or triple vomit.

Learning to vomit twice (or vomit three times) is actually to find the feeling. Keep practicing on the cucurbit flute, practice every day, calm down and practice, don't just practice for a few days and get bored if you can't find the feeling, keep practicing. If you are tired of practice, take a rest, then practice again or adjust your mentality and practice again tomorrow. After practicing a lot, I suddenly found the feeling one day. Once you find the feeling, don't stop right away, practice it for another twenty to thirty minutes, don't let the feeling run away, let it settle down. Practice again tomorrow, grasp the feeling, keep practicing for one or two weeks, this feeling will be stable, and double vomiting can be regarded as a preliminary learning. The next step is to study according to the double spit etudes, from easy etudes to difficult etudes. Shuangtu is the basic skill of cucurbit flute playing and should be practiced for a while every day.

After a little bit of practice in double vomit, the tongue movement range can be practiced with a smaller range to improve the speed of double vomit.
