How to play the flute?

I'm not very clear about playing, such as how to play high notes. In fact, there is no trick. If a teacher teaches you, you may watch it once, and then the teacher tells you that you are OK. But considering that you are self-taught, let me talk about it.

Flute can play three different sounds: bass, alto and treble. You said you had more than 600 flutes. Daily life is good, but the major is not so good. Your flute can not only play low, medium and high, but also play an octave higher and play four different sounds, so there is nothing wrong with your flute. This is your playing problem.

There are two nouns, harmonic damper. Generally speaking, tuning is the size of the airflow when playing, and the damper is naturally a place to vent.

Generally speaking, when playing alto, you should first practice the fingering of 5 on the barrel sound, hold all your fingers down, and blow and blow naturally. Then on this basis, you will find that the sound will be obviously different when you blow hard, that is, playing high notes. You can experience it yourself. When playing alto, the tone is slow, while when playing alto, the tone is urgent. It is very small. Feel the breeze and damper. If it still doesn't blow out, check whether your flute membrane is tight and there is no leakage. If not, you can find a teacher to learn.
