Preparation before tuning the JiaoYe Guqin
Due to the wavy shape of the Jiaoye Qin, the tuning work is different from the common Guqin. After the accessories are inlaid, and begin to estimate in advance the coating height that will be increased due to the cloth wrap and ash scraping, and when cutting hardwood parts later, a certain tolerance value can be reserved for the critical height.
After the Jiaoye Qin shaped, the soundboard and backboard each have a special half-wave shape after being separated. Therefore, at the beginning of the tuning stage, three stages need to be divided cleary: the pitch expect, tone fine-tunnig and the final timbre fine-tunning. And each step must reserve a fairly flexible adjustable range for the next step to be calibrated.
In short, when the accessories are available, the best and lowest natural frequency range that the Guqin soundboard can be achieved by thinning is preliminarily estimated, so as to plan the overall and partial thinning in advance.
