When you play the same piano, sometimes you feel that the keys are light and elastic, but when you play it every few days, you feel heavy and the keys are inelastic. What happened?

1, the parts of the keys are different. Playing the white key near the lower part of yourself will make you feel lighter, and playing the white key near the upper part of black keys will make you feel lighter.

2. Have you ever played another piano in the middle of playing twice, and the feel may be different;

3. Is it time to tune your piano, or has something fallen into the keys?

4. I have had this feeling. When it's cold and your hands are cold, you will feel that you are playing very hard. When the weather is warm and your hands are not cold, you will naturally play comfortably and lightly.

I hope the above will help you.
