Clavier tuning is a method of violin making, estimated to have been used by Stradivari and Guanelli 300 years ago to create their plates using the percussion sound of the lute. As a result, those who previously knew this method lost the advantage of being a prophet. I hope those who have lost the advantage of being prophets will not feel regretful. As long as you are a genius, you will discover other windows that ordinary people cannot see. After understanding a problem, people often exclaim that the solution is as simple as puncturing a window paper. But before the problem is solved, there will be countless windows in front of people, and most of them are walls with stickers behind the window paper, which cannot be punctured. Only a very, very small amount of window paper can be punctured. That is to say, without a smart mind, discovering problems may not necessarily lead to finding the right solution. That's all for the metaphors, so what is piano tuning? Dr. Hawkins' vibration pattern tuning method is one of them, but it was just a set of data she provided, which was proven wrong through experiments with me and several friends! Take a look at the photos of Teacher Tao Baohua making and repairing violins. He uses a small wooden mallet to strike the violin board, which is another method of tuning the board! Everyone has also seen the scene of Master Morasi holding the qin board and tapping it to listen. He is judging the quality of the qin board production by listening to the tapping sound! There should be many methods, but the specific operating methods and standards are key. It's not just random tapping, the tapping sound has a frequency range and frequency range of tapping points! It can control the precision of violin making! There is a message on the forum that says' According to an Italian luthier, the panel is f or # f, of course referring to Italian materials'. I think it should refer to the frequency of Mode 2 of the lacquered piano board removed after completion. How to make the whiteboard sound f or # f or a specific frequency range after completion is the knowledge or technique of tuning the piano board. What I'm talking about is no longer just throwing a brick to attract jade, but being more specific will limit everyone's imagination and creativity! Finally, please remember that tuning the violin board is not the only method of violin making. Material, shape, structure, and production quality are also very important. Plate tuning is just one of the indispensable methods for making a good violin.

But why do you say that? It is because the shape of the violin is determined by the curve of its outer surface. Once the shape is determined, it is necessary to process the thickness from the inside. What is the appropriate thickness? Using a uniform size is definitely wrong! Because the material of each board is different. Using a tuning board to determine thickness, that is, using audio accuracy to make the thickness of the piano board! However, the prerequisite is that the thickness of the piano board must be relatively balanced in geometric dimensions, and its contour lines are very regular. The thickness of the piano board is not uneven in certain areas, but rather distributed as a whole with uniform thickness in certain areas.
