Hehe, my friend, in fact, the hand-cranked piano can only be used for entertainment. If you want to practice finger kung fu, I'm afraid you have to use the traditional piano. You see, the keys of the hand-cranked piano can't be pressed, and there is no key resistance. How to exercise your fingers? It's better to practice electric steel, but it's easy to carry and can only be used for entertainment ~
The sense of reality is quite poor, and the sound is much worse than the electronic organ.
