Yueshan and Chenglu embedding

Guqin accessorie parts are divided into primary and secondary, among which Yueshan and Chenglu are belongs to the main parts of sound-bearing. Its function to bearing the vibration of the strings together with the Longyin at the otherside and transmit the vibration to the entire Qin body, then converting it into sound.

As for the main parts, it occupy a considerable proportion in the timbre of the Guqin. The selection of woods, the technological structure of the embed, the scale of embed depth, and the angle of embed will affect the transmission efficiency and stress angle of the strings during vibration. And it is precisely because of this detail that invisibly affects the overall performance of Qin. Although its proportion is not so significant, but it can be described as subtle, also appears precious in craftsmanship.

However, there is also a telling in the Guqin industry that ten Qin are nine cracks have. No matter how well the craftsmanship done, it is inevitable that certain cracks will appear after a long time. Among them, the two hardwoods of Yueshan and Chenglu are embed (mount ) into the headstock of fir or paulownia make’s Qin. Due to the different seasonal shrinkage ratios of the three parts (woods), they have different shrinkage and expansion coefficients, so it is inevitable that they will appear subtle differences crevice between each other over time.

Therefore, in order to minimize the different effects of the shrinkage crevice (gaps) for the timbre, the embed process needs to take into account the antecedents and consequences brought about before the passage of time. Then it is necessary to stable the crevice and tension release directions generated by different seasonal changes, and to maintain the tensile and stress strength of the strings. In simple; the vicissitudes of life are natural as the time go by, and the tension of life is still energetic.
