1. Gesture: When your hands are folded, there should be no air leakage except a small hole between your thumbs.

2, mouth and hand coordination: in the case of correct gestures, gently stick the joint parts of the two thumbs between the lips.

3. Breath and playing: After the gesture and mouth are in place, gently blow through the small hole between the two thumbs, and you can hear the sound of "whoop … whoop", that is, the basic sound. If there is no noise, check the above two items, and then blow until a stable sound is blown out, and the basic skills are preliminarily practiced.

4. Playing the scale: On the basis of playing a tone freely, practice the ascending or descending scale with this tone as any one of 1/3/5. The way to change the pitch is to adjust the opening and closing of the outer hand. When you can play a stable 8-degree interval, you can try to play a melody that you are familiar with.

The hand is hollow, leaving only a small hole between the two thumbs for blowing holes. With the help of lips and breath, music can be played by changing the size, opening and closing of the cavity formed by hands and the strength of breath.
