屋根も鍵盤蓋も開閉出来ます。
鍵盤を押すとハンマーが連動して上がります。
でも音は出ません。
I made this miniature piano 5 years ago.
You can open and shut both lid and fall (covers keys).
There is a hammer action, even though it is quite simplified
works when the individual key is pressed
but there is no sound.
It is a good size for Charmy.
What are you playing?
