回复：立式琴发音像戴着口罩唱歌。大小立式琴差价跟音质差别不成比例

The space inside a piano is very important. The space amplifies the sound. The echo of sound in the space would make the sound stay longer for larger space. Withour enough space, the sound would not mix because each tone of key last too short. A low piano does not give a smooth music. It's alright for a child to play on a low piano at the neginning. When advancing to level 6 or above in the royal school scale, you have to change to a better piano. So why waste money to buy two unless you plan for this just playing it for fun. There is no doubt the grand pianos have better qualities, but I feel your argumants are funny. Because 李云迪朗朗 use grand piano, the buy grand piano otherwise buy 小型立式琴经济实惠. In my opinion, buy something appropriate to oneself instead thinking that "Bill Gates quite school and became the richest man, I'll do the same." We know most of us are not Gates.
