Under normal circumstances, the sound of the cucurbit flute supplemented by the pipe and the main sound of the same level should be the same pitch. Some of the main sound of the cucurbit flute and the sound of the supplementary pipe have deviations. When the two sounds are sounded at the same time, it feels very harsh. At this time, it is necessary to confirm first. In the end, whether the main voice has been audibly accurate, and then determine whether the auxiliary voice is high or low.

If the difference is not large, the hole pressing method can be used to determine, for example: first cover part of the attached pipe with your fingers, open the 3 sound holes of the main pipe, and play two sounds at the same time, cover the attached pipe while blowing. Raise the finger of the tone slowly. If the two tones are very unified without the fingers being fully opened, it means that the pitch of the attached pipe is high; another method is to fully open the attached pipe and cover part of the main head 3 with your fingers. (Mi) sound hole, blow two tones at the same time, and slowly lift the finger covering the 3 (Mi) sound. When the 3 (Mi) sound hole is not fully opened, it feels that the two sounds are unified. At this time, you can It is concluded that the attached pipe sound is low. If the sound of the attached pipe is low, you can cut off the attached pipe a little, or dig 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 (depending on 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.
