Is it cheating to spill the keys?

The keys are covered with liars. The reason is that water enters the piano and water enters the keys.

1. Moisture enters the piano: The piano consists of many tiny wood and metal parts. If moisture enters the piano, it will cause corrosion, expansion or deformation, thus affecting the sound quality and performance of the piano.

2. Moisture enters the key: When water is sprayed on the key, moisture will penetrate into the key, causing the key to get stuck or operate insensitively. This will affect the accuracy and comfort of playing.
