Too high a string is called finger resistance, which will affect the playing method and make the fingers tired. Generally speaking, the finger resistance of the strings is not only because the moon mountain is too high, but also because the bow of the piano is not enough.
It should also be noted that some pianos bow their heads enough, and the moon mountain is also suitable, but the middle part of the piano bends downward, which is called bending, and it is also necessary to resist fingers. On the contrary, if you bow your back, there will be problems such as string pressing and sand sound.
2. The piano surface can't be peaceful. If you press the lyre with your left hand, there will be no obstacle, but it will be difficult to press the first, second, third and fourth strings on or above the seven emblems. Although some pianos are flat, they are easily overlooked, because the radians on both sides outside the strings are very large, or they are flat only above the four emblems.
3. Chord spacing should not be too wide or too narrow. The width of chord distance refers to the distance between the chords of the Moon Mountain. Some pianos are short of materials, and the distance between the two lines is very narrow, which will make the pianist's fingers stiff. If it is too wide, it is difficult to control.
4. The effective chord length of the piano refers to the length from Yueshan Mountain Pass to Longjiao at the tail.
5, the piano surface should be flat. Some piano faces are not well made. Besides the uneven paint surface, there are also unevenness, which will produce sand sound.
6. The choice of piano sound is the judgment of the piano itself.
