If you want to make the sound quality of the erhu better, you can replace the piano code with better material or shape, or replace the jack wire with better quality, which can also solve the sound quality problem to a certain extent.

If the pronunciation of the erhu is dull, you can use a small round file to expand the small hole of the piano code. If the sound of the erhu is sharper, you should choose a piano with a big hole and a small hole at the bottom, so that the problem of the sound quality of the erhu can be solved.

The barrel and stem of the erhu are generally made of red sandalwood, ebony, mahogany and other hard woods, which are easily affected by climate. Therefore, it is necessary to properly adjust the humidity in the piano box according to the climate, so as to ensure that the piano and the piano rod will not crack due to drying, or degummed due to moisture, and at the same time, the sound quality of the erhu can be kept stable.

The piano code of the erhu is an important conductive component, which has a great influence on the sound quality of the erhu. The owner of each erhu should choose a suitable piano saddle for his erhu, which can make the sound quality of the erhu better. At the same time, sand the top and bottom of the bridge alternately with fine sandpaper, so that the round hole of the bridge remains in the middle position until the height is suitable.
