The top of the guzheng is made of soft paulownia wood, and the influence of the weather on it is reflected directly through the strings. Therefore, when the weather changes greatly, it is best to tune all the tones, rather than just one set.

If the bridge is not straight, even if you just tune the string, it is easy to run away. So, be sure to put the bridge upright, perpendicular to the strings, so that the strings just fit into the grooves of the bridge, so that the pitch will be relatively stable!

When you put new strings on the guzheng, be sure to pull and press it with your hands until you press the glissando without going out of tune. Because the tension of the newly wound strings has not been opened, the elasticity is relatively large, but through the repeated actions of pressing - tightening the shaft - pressing again, the tension of the strings can be fully stretched, and the intonation can be relatively stable. .

When the playing strength is different, the amplitude of the vibration of the string will change accordingly, so the pitch will be different according to the frequency of the vibration of the string. Also, the frequency at which the strings vibrate changes when played in different positions, especially when the bass is played vigorously. Therefore, it is best to tune in a relatively uniform position to ensure that the amplitude of the vibration of the strings is relatively the same.

After tuning with the tuner, listen to the pitch again with your own ears. There will be a certain deviation between the human ear and the machine's perception of pitch. After the ear finds an uncomfortable pitch, make detailed adjustments. Repeat this, and slowly you will find that the piano is out of tune less and less, and The ear's recognition of pitch will be greatly improved.
