The Relationship Between The Pattern And Timbre Of The Violin Back Panel
　　 Many people think that the qin back panel has a good pattern, and the violin must be good or high-quality. This is actually a beautiful misunderstanding. Many precious violins with prices in the millions of dollars have little or no back panel pattern. The cheap and low-end qin produced by some factories sometimes has beautiful and eye-catching patterns. Generally, many factories directly buy logs or buy wood in bulk, and there is also a great opportunity to buy maple wood with beautiful patterns.Generally speaking, the role of the backplane pattern is mainly decorative, and it does not help the acoustic quality of the violin backplane much.First of all, let's talk about the pattern of the maple wood used in the violin backboard. Generally speaking, the direction of wood fiber growth is the same as the direction of tree growth and height, but maple fibers with patterns (especially maple trees with beautiful patterns) curl and grow in a wavy shape. On the longitudinal section of the trunk, due to the ups and downs of the wood

fibers, the absorption and reflection of incident light are different. The patterns that are manifested as light and dark or diverse forms are what we usually call patterns. If considered from an acoustic point of view, the wood fibers are long and neatly arranged. It will have a good resonance effect.During Qin board processing, many wood fibers will be cut off due to the curvature and thickness of the production, so that the wood fibers of the Qin board are no longer continuous in many places.Obviously, the more curly the wood fiber (that is, the better the pattern), the more chance it will be cut off in multiple places, and the shorter the fiber. This affects the strength and elasticity of the entire backplane, and the adverse effects on the acoustic effect are self-evident., Therefore, in history, some Italian qin makers have specially avoided maple wood with too deep tiger skin patterns. Maple wood with patterns accounts for about three-thousandths of all maple wood, which is very rare, so the wood is expensive.However, the acoustic quality of wood does not depend on the appearance attributes such as the thickness, size and direction of the pattern. The acoustic quality of wood is determined by the age of the wood, the wood rays, the color of the material, and even the timing of the logging. The sound quality of a qin depends not only on the acoustic quality of the wood, but also on the matching of the violin's back panel, the arc structure of the board, the production process, and the paint.
