There is also an agreement that the accordion on the first floor is not as long as possible, but as long as possible without aging. This time is related to the quality of pro. The parrot piano with a price of 4,000 yuan will have the best sound after playing for three to five years (of course, this is also related to the time of practicing the piano every day). After seven or eight years, it will wear out and the sound will get worse and worse. The longer you talk, the better. You should mean Italian Boucary, German Helai or Russian Ubit. These pianos are worth more than 7w yuan.
It is difficult to choose a good two-handed piano for your voice, and the scope of the club is relatively small. In addition, the maintenance of piano is very important. You can choose the golden cup and parrot five years ago, and now it's Bai Di.
I have four pianos myself, two of which I never use, but I certainly won't buy them, because the pianos are very good and I maintain them well, and I have feelings. Therefore, if someone wants to sell a two-handed piano, at least one thing should be said: he is not well maintained, and second, he has no feelings for the piano.
