How does the weather change affect the piano?

The change of temperature and humidity will directly affect the quality of piano. For example, when the weather is wet, the wood will swell, causing the keys to be insensitive and not bounce. If it is too dry, it will shrink the wood and loosen the parts, so try to avoid putting it in the stove, air conditioning outlet or direct sunlight. The most ideal place is to place the piano at a humidity of 50%-65% and a temperature of 10-25.
