2. Use both hands to tighten the edge of the blade playing as a musical instrument to form a "reed" with a lip length of about 1/3 and a width of about 1~ 1.5mm for playing. (Note that the "reed" should not be too wide. The narrower the reed, the sharper the sound. The easier it is to make noise, this is the key)
3. When the blade is close to the outside of the lip, the contact non-contact state of the upper and lower lip blades is formed.
4. Blow or inhale the gas from the abdomen, and make the lips slightly open from the closed position, so that the airflow can partially pass. At this time, the blade will make the sound you want.
5, use the size of the airflow, control how much, and blow out the tone.
