1. The ring finger, middle finger and index finger of the right hand open and close the first, second and third sound holes with the first finger pulp respectively, and the thumb is dragged under the main pipe. The ring finger, middle finger and index finger of the left hand are opened and closed with the belly of the first finger, and the thumb is opened with the fourth, fifth and sixth sound holes, which are located at the front and lower part of the main pipe. ?

2. Take a deep breath and inhale as much gas as possible. After inhaling, the breath sinks, so that the airflow can be exhaled evenly and evenly in a controlled way, and the breath should be stable, not strong and weak. ?

3. The little fingers attached to the left and right sides of the sound tube should not be fixed, and they should be mastered flexibly according to the situation when playing. For example, when playing with the upper three fingers (that is, opening and closing the 456 sound hole), the little finger of the right hand should be attached to the lower side of the first sound hole, and the little finger of the left hand can naturally be raised with the performance. This will not affect the flexible use of the upper three fingers when playing.

4. When each sound hole is pressed (closed), be sure to press the sound hole with the first finger pulp to avoid air leakage, otherwise it will affect the pitch and timbre. When playing cucurbit silk, you should relax your arms and wrists and bend your fingers inward moderately. Don't raise your fingers too high when opening the sound hole. Too high will affect the performance speed and flexibility, but it should not be too low. Too low will affect the pitch and volume.
