What should I do if the sound of the cucurbit flute is not allowed? The problem of inaccurate playing can be checked and adjusted from the following aspects.

Check whether the cucurbit flute meets the standard requirements: whether the pitch and pitch are accurate, and whether the sound appearance is good.

Check that the fingers are open and closed when playing and whether they are in place and meet the requirements. For example, when closing the sound hole, it is required that the finger pressing the hole must be pressed with the belly of the sound hole, so as not to leak air. When the finger is opened, the finger should be at a certain distance from the sound hole, not too close, otherwise it will affect the intonation.

Whether the use of breath control is good. When playing a musical instrument, the movement of the breath should be stable and balanced, and it should not be strong or weak. Pay attention to the level control of the strength of the breath when playing the high and low frequencies, that is, when playing the bass, the breath should be stronger (except when the bass is played as "sol shuttle [5]" for the bass "mi microphone [3]"). When playing high notes, the breath should be reduced accordingly.
