How to tune the piano? My piano has not been tuned for more than two years, and the tone is always inaccurate. How much is this bill? What do you recommend? My piano is Xinghai.

If it is not adjusted for more than two years, it must be adjusted. Optical tuning is not expensive, 80~ 100. If you want to check and repair the string mixer, it will be very expensive. A string of beads costs 20 yuan, but it will be broken as soon as it is broken ~ but it may need to be inspected after two years. If you buy a piano, no matter what brand, color or style, the important thing is tone and touch. When you buy it, you must try whether the treble is bright, the bass is mellow, and the keys are strong or weak. Then choose your favorite brand, color and style ~ ~ ~
