The new erhu has just started to play, the sound is simmering, the noise is prominent, the wolf sound is frequent, dry, not soft, etc. It takes a period of time to recuperate or call it a running-in period, that is, the opening of the sound. The erhu uses the strings to drive the python skin to vibrate and produce sound. The python skin is the core component of the erhu. The python skin is relatively tight at first, and its fibrous tissue is in a disordered state. It's uncomfortable and unpleasant to listen to, so it's necessary to "acclimate".
"A good erhu is pulled out", this sentence is very correct. The "training" of the new piano should be comprehensive, longbow, shortbow, heavy bow, and light bow should be practiced, and every note in the mid-range and high-range areas should be taken care of, especially the positions of the inner strings. Practice a lot, because the outer strings are often used and the inner strings are used less. After a period of time, the python skin vibrates more regularly, and the sound it emits is rounder, smoother, softer and more beautiful, and at the same time, the volume is also increased, which means the sound is turned on.
In order to practice each note, the new piano should practice more scales, and the fingerings of various keys are from low to high, so that each note can be practiced.
The length of the break-in period is determined by the player. If you are a student majoring in erhu at the Conservatory of Music, you can play seven or eight hours a day, maybe a few months. If you have a handy erhu, you have to practice hard, at least have a certain amount of time every day to practice the piano.
The practice method of opening the tone is no different from the usual practice. Erhu players who have a certain foundation have more advantages in the open tone, as long as beginners practice according to the textbook.
Introduce a few tips, I don't know if they are useful to you?
① Before using the new piano, apply a layer of (thinner) animal fat on the python skin, (we live in the north, the climate is very dry. This method may not be applicable to the south) The sound will be much better.
②For the treatment of wolf sound, it is best to use woolen (ie wool cloth) as the sound pad, which is better than the sound pad of other materials such as sponge.
③The shaft of the new piano is not easy enough when it is first used (except for the metal spiral shaft), it is easy to get stuck or slipped, and it will cause trouble to set the strings. The method of spitting by folk artists is very effective.
A new piano is like a new car. If you want to drive it as you want, you must run it in properly, and then you can "unify the human and the piano"; just like a newly married couple, no matter how beautiful their love is, they have to go through "chai, rice, oil, salt, sauce, vinegar and tea". Baptism, will mature.
