You can't leave your nails when you play the piano. Nails can be colored without long nails, but they will grow out in two days and have to be cut off and redone. Theoretically, if it's no trouble. But if you want to learn the piano well, you'd better put aside what you like. If you spend too much time on other things, you will naturally spend less time on study and piano, and your energy will be limited. There is also a manicure that can easily distract you while playing the piano. For example, when you are playing music and looking down at your nails, you will inevitably think, what about this pattern? Oh, then why didn't you choose that pattern? I like that, too. I hope you will consider it carefully!
