Angle problem, find a good position, play a long tone, keep the mouthpiece relationship unchanged, and raise or lower the angle of the flute at the same time, you will find the best position: volume.

Maximum, minimum air leakage, the most beautiful timbre, a little transparent taste, easy to blow from flute 5 to flute 6.

This is the best angle, and the angle range is relatively small, so remember and practice.

As for the strength, it should be changed according to the strength requirements of music.

pay attention to

Play it very well, beginners may not be able to play it. There are two reasons, one is that the mouth shape is wrong; Second, the quality of the instrument itself is not good. It doesn't matter much, because the treble is not often used or not used at all. At this time, I just introduced it to my friends, and the flute can also play super-high sounds like a flute.

The second octave of the barrel sound and the second sound above it should be playable.

The high notes 5 and 6 are awesome. These two sounds are often encountered in difficult music. When practicing these two sounds, your mouth should be firm and you should give enough confidence. This folk proverb is apt. We should understand it this way: your mouth is important, the air door should be slightly opened, and your tone should be more focused. The whole breath should be controlled in dantian, and it is not difficult to blow out high notes 5 and 6.

Overtone of flute

Overtone fingering is not commonly used. The fifth tone in Xiao's overtone series is the brightest. Theoretically, all sound holes have overtones, but the only overtones that Xiao can blow out are drum sounds and holes one, two and three. In fact, another fingering of the high note 5 of the flute in G key is the overtone of 1 Take the flute in G key as an example, the drum sound and the first, second and third hole sounds can blow out the fifth overtone. This drum sound does not refer to the bass 5, but to the alto 5. The first, second and third holes are also 6 and 7 in the alto and 1 in the treble.

When the drum is 5:

Local tone: 5 6 7 treble 1

Overtone: treble 2 3 4 5 (2 holes with half holes are 4)

When practicing overtones, you should first blow out local sounds, and moderate and weak intensity is enough. On this basis, the damper will narrow slightly, arch slightly, and the overtone will be blown out. In practice, you can feel a threshold between overtones and local sounds. Can't cross the threshold, can't blow the overtone. You can't be impatient at this time, because if you are impatient, it will be uneven and useless. Take your time. Why do you say "gas micro-arch"? Because it's actually a little bit, and the gas is too big and too small to blow out. As long as you pass the critical point (threshold), you will get a perfect overtone. If you are proficient in overtones, there will be no sense of "threshold".

The overtone is the pure fifth of this hole sound. Therefore, through overtones, we can also correct the relationship between the Kong Yuan hole and the upper fifth hole, and we get four overtones, which can carefully correct all the interval relationships. First, the pitch of the sound hole itself is corrected by overtones. For example, blowing a high note 2 on the fifth note can be compared with the pitch of the high note 2 on the fourth hole to hear whether it is high or low, and then decide whether to adjust the barrel or the fourth hole. Adjustment method: If the pitch is available, stick a strip above the sound hole with rubber strip, or block it with yellow wax. (If the sound is low, you can dig a little above the sound hole with a knife. But after repeated tests, you must dig when the sound is definitely low. You must dig a little and try. Never pick up a knife and dig. If you dig too much, you should seal it with wax, so the good flute will be scrapped.

When the drum sound is 1:

Local voice: 1 2 3 4

Overtone: 5 6 7 treble 1

When the drum is 2:

Local voice: 2 3 4 5

Overtone: 6 7 treble 1 2

When the drums are 6:

Local sound: bass 6 7 alto 1 2

Overtone: 3 4 5 6 (the first hole is halved to 4)

Harmonic symbol: draw a small circle above the note.

The volume of the flute is not large, and the intensity of overtone blowing is even weaker. However, due to the relatively concentrated tone when playing overtones, overtones are actually weak and not empty, and the sound should be straight, and abdominal vibrato cannot be added.
