Erhu Maintenance in Wet Weather It has been raining for more than a month in the south, and the air is very humid. Erhu is rarely used, and it is reluctant to give up. I put a few high-end pianos in the closet. There is a large bottle filled with quicklime. The lime is covered with a little toilet paper. The whole cabinet is very dry. When I take out the piano and pull it, the sound is clear and crisp. No, if you pull it for too long, you can even put it away in ten minutes, and the strings must be loosened. Just putting some so-called desiccant in the box is of no use to me. I don't know how everyone does it.

The humidity suitable for erhu is between 40-60. The humidity of the erhu without sound is slightly higher. For the erhu that has been sounded and the sound is relatively stable, more attention should be paid. Because I am in the north, there are a lot of dry days, and even rainy days are considered wet weather. I have a hygrometer at home. Check the hygrometer before playing the piano. If it is lower than 40, I will use a mop to wet the ground, or use a pot to open the lid on the stove to boil water. In winter, the indoor heating is even more dry. I put the water box all over the heater. If it is higher than 60, dry it on the stove with two towels and put it in the piano box. It's basically out of the box. If you don't approve it, it doesn't sound good if you pull it. Just like the landlord said, you can't bear it. It is very necessary to loosen the strings when the humidity is high, monitoring with a hygrometer is also very necessary, and it is even more necessary to take good care of the erhu.
