Here are the differences with the first version: 1/ Tone Some netizens commented that the tone of the 25-key piano is harsher. The reason is that the first version uses the left young body's vocal aluminum stick to make it. The high pitch, loudness and lingering sound of Li are very long. If you play a longer song , The surplus sounds will become harsh when they are overlapped and buried; the improved version uses thick aluminum sticks, and you can hear the sound from the fragments, and it is more rounded, and the surplus is short and left. It sounds comfortable to the left~ 2/ size The depth of the piano depends on the length of the aluminum branches. The modified version uses the left thick aluminum branches. The length of the aluminum branches can be shortened proportionally. Therefore, the depth of the piano body is naturally short, not bulky, and does not occupy the position~ 3/ Stopper In the same way, to solve the problem of too long residual sound for the left, the improved version is to add a left stopper to the vocal part, which can instantly stop the residual sound~~~ - I understand that you are worried about your own repairs. Compared with the accordion, the grand piano does require more time to complete. In addition to the more parts, there are also more steps to repeat (such as repeating the key and threading the aluminum stick). You need It’s a simple carpentry. However, it’s not as difficult as an accordion in terms of skills. You don’t need to fold the most difficult bellows. Basically follow the teaching step by step, and you can do it with a little patience!
