18th century is the heyday of violin making technology. At that time, the techniques of making piano and lacquer were the best. Later, with the death of the piano master in the18th century, the top-notch production skills at that time were also lost. So far, there is no piano-making technology that can surpass18th century. So those old pianos at that time can now shoot hundreds of millions of RMB.

The violins made by stradivari, Guanelli and Amati, the ancient Italian pianists, have excellent timbre, mainly because they are full of resonance sounds accompanied by the tonic. The factors that affect the timbre include the shape of the piano body, the thickness of each part of the piano board, the materials of the front panel and the back panel, whether it has been honed by long-term vibration, the dry state of the wood, etc. These are all important reasons for the superiority of the guqin, because it has been proved that even if the modern imitation piano is exactly the same as stradivari, Guanelli and Amati, it can't reach the timbre of the guqin. According to foreign scholars, this is mainly because Guqin wood has a special microporous structure.

At that time, Clermona, Italy was the piano manufacturing center, and the required wood was discharged from the river to the seaside. The wood is soaked in water, fished ashore, cut into appropriate sizes, and then sold to the piano maker. The tradition of Italian piano makers is that wood should be dried naturally, and it is often used by grandparents, so the wood is dried quite well, especially the soaked wood, and the micropore structure formed during the drying process is developed. Modern means of transportation are developed, and there is basically no need to put rafts. The storage time of wood is generally 10~30 years, which cannot compete with guqin, even if it is copied. I wanted to upload a picture of relevant information, but I failed several times. Please forgive me.
