Guqin emblem inlaying and accessory engraving

The engraving accuracy and displacement correction of the emblems（similar to the frets of Guitar ） inlay will complement the player’s performance, and even determine the pitch of the Guqin and the brightness of the harmonic to a certain extent. Because the emblems are inlaid on the curved surface, and there has a certain angle between the strings and the Guqin surface, there has a corresponding slight visual offset.

There are two main schemes for the emblem (Hui) inlay: 1. Drill holes and inlay after the Guqin’s soundboard and backboard bonding or cloth wrapping. 2. Engraving and inlaying after the Guqin fine ash or string path smoothing stage.

Then there are three kinds of positioning of the emblem (Hui) inlay scheme: 1. Be parallel to the distance of 8mm-10mm outside the first string, and drill it as the center of the circle. 2. Parallel to 7mm-8mm the outside of first string as a circle periphery for engraving. 3. Establish 2 points of first emblem and thirteen emblem outside 7mm of the first string and establish the midpoint 9-12mm outside the seventh emblem, Then three points are connected to form two straight lines and thirteen emblem center points are arranged it. As for the vertical positioning of the exact thirteen emblems, the fourth string or the average central point of the first, fourth and seventh strings is used as the vertical alignment points.

As for deviations there are usually: 1. The hanging angle between the Qin surface and the strings. 2. The oblique vision difference caused by the curved surface of the Qin body. 3. The natural bending or twisting of the Qin caused by force during the production process or after. 4. A series of positioning, dimension and sketch tolerances caused by the inlaying operation. 5. Ruler and tool maintenance and human mistakes derived from the operation process. Combining various causal details, the cumulative displacement will obviously intervene the player’s playing habits, and it also realise that a certain period of playing and running-in is required between the player and Qin in the later period.
