Under normal circumstances, the pitch of the attached pipe of the cucurbit flute should be the same as the pitch of the supervisor at the same level. If there is a deviation between the main tone of the cucurbit flute and the attached pipe, it will be harsh when the sound is produced. At this time, it is necessary to first determine whether the main sound is from the auditory. The above is accurate, and then determine whether the attached pipe sound is high or low.

If the difference is not big, you can use the hole pressing method to determine it. The first method: first cover part of the attached pipe with your fingers, open the main 3 sound hole, and play two tones at the same time, while blowing, slowly raise the finger covering the attached pipe. If the fingers are not fully opened In this case, the two tones are very unified, which means the pitch of the attached pipe; the second method: fully open the attached pipe, cover part of the sound hole of the main 3 (Mi) with your fingers, and play the two tones at the same time. , the finger covering the 3 (Mi) sound is slowly lifted. When the 3 (Mi) sound hole is not fully opened, it feels that the two sounds are unified, which means that the sound attached to the pipe is low.

Solution: The sound of the attached pipe is low, you can cut off the attached pipe a little, or dig out the edge of the pipe hole a little bit, so that the sound of the attached pipe will increase. If the sound of the attached pipe is too high, you need to use a thin bamboo stick to insert it from the mouth of the attached pipe, touch the tuning plug of the attached pipe, and gently push the tuning plug in a little bit (according to the specific height of the attached pipe). The adjustment depth is determined according to the situation), and only a maximum of one millimeter is allowed to be pushed at a time (more pushes will make the sound lower, and a section of the nozzle should be cut off), and try to blow while adjusting until it is accurate. Under normal circumstances, when the intonation of the attached pipe is relatively good, when playing all the scales with the attached pipe, the overall feeling of hearing is more comfortable.

If your cucurbit flute is inaccurate during use, you can refer to the above methods to make appropriate adjustments to make your cucurbit flute to your heart's content.
