Installing the bridge requires finding an optimal resonance point on the piano skin

1. Find the best resonance point

Generally speaking, the position of the bridge should be placed in the middle of the piano skin. This statement is also true. I think it is accurate to find the best resonance point. Because the sound column of the violin is the same, if it is a little bit off, it is not the best resonance point, and it is not necessarily a string that vibrates badly and the pronunciation is not full. The same is true for the erhu. The saddle is an important part that transmits the sound of the strings. If you press it a little off, it will not be at the optimal resonance point, and the vibration of the erhu will be relatively attenuated.

1. First of all, start from the string groove of the piano holder to the piano yard. Whether the two strings are perpendicular to a line, and whether the center of the two grooves of the string groove of the piano support is in a line with the center of the piano skin, you can measure it with a caliper, use eyes to see.

2. The position where the piano code is pressed: move up 0.5mm from the center of the piano skin, and find the best resonance point within the range of 0.5mm.

2. Protection of the best resonance point

1. First, look at the position of the piano code with your eyes, and remember it.

2. You can loosen the strings after every time you play the piano. After the next tuning, use your index finger and thumb to pinch the bridge and pull it down, and then use your index finger to flick it up a few times to make the bridge close to the piano skin. . This is because when the strings are tightened, the string skin moves up gradually, driving the bridge up, resulting in the phenomenon that the feet of the bridge are tightened and loosened.

3. After remembering the position of the saddle at the best resonance point, wipe the bottom of the saddle on the bow hair a few times, and then put it back in place to prevent the saddle from shifting.
