There are many factors that influence when we should change strings, the most common being poor feel, poor tone, and rusted strings.

But in fact, one day, when you find that your strings are always out of tune, or even begin to rust, this is already the limit state of the strings, and it has caused trouble for your usual piano practice. In this case, you should have earlier Be aware and replace strings in time.

Bad feel

This is caused by aging strings, also known as "metal fatigue". Because the steel string continuously experiences "bending" and "stretching" during the playing process, and its elasticity gradually decreases, so when our hand feels obviously loose or tight, it is necessary to change the string.

However, changing the strings is a bit complicated after all. Compared with the unavoidable factor of breaking the strings, if the feel is not good, you can not change the strings. Runyang said: "Yes." This requires you to choose high-quality strings from the beginning.

The general guzheng strings are covered with nylon and built-in steel wire. For the more advanced strings, the basic string material has been optimized and upgraded, and the outer nylon material is integrated with silk to make the strings smooth and soft. .

The built-in steel wire is upgraded to a high-carbon steel wire, which makes the strings more flexible, relaxed and elastic when playing, and the sound is bright and round.

Choosing high-quality strings does not allow you to change strings "once and for all", but greatly reduces the frequency of string changes while improving the feel. Guzheng has 21 strings, and it is very tiring to change every three or five.

murmur

There are generally two types of noise. The first is new strings, and the second is after strings are aged. Why do new strings have noise? To be precise, the noise at this time is the "metallic feeling of the new strings." This metallic feeling is irreplaceable, so many zheng friends are reluctant to change the new strings for this reason. When you pluck the new strings, you hear the sound of the strings, and when you pluck the old ones, you hear the sound of the guzheng. Many zheng friends also like the strings whose "metallicity" disappears, and like to like them , the strings are broken.

Therefore, it is still necessary to choose high-quality strings from the beginning. Good-quality strings have a soft feel and a crisp sound. Even if they are new strings, there will be no "metallic" noise that disturbs your heart.

After a period of use, the second kind of murmur zither string may damage the nylon cladding wrapped around the zither string due to excessive force or unrounded nails. Playing this zither string will become dull. It becomes cloudy and weak, and the strings should be replaced at this time.

Rusty strings

The acid produced by the sweat on the human hands will react chemically with the metal, and some dirt and horny on the hands will accumulate in the outer coil of the strings, which will cause the strings to rust and even become black and sticky. of.

To prolong the life of your strings, you must keep them clean and hygienic. Before playing the guzheng, take some time to wash your hands; after playing, wipe the strings with a soft cloth. I'm usually really lazy, just change the strings once a month, it's too late when the strings break.
