Erhu has entered a new era of acoustic vibrato, and it is very necessary to re-understand the principles and importance of the three elements of vibrato. First of all, it is necessary to know that the road of erhu accent is the only correct and practice-proven direction that must be moved forward. To move in the right direction, we must fully and correctly understand the three elements of vibrato.

1. Frequency

What is the most correct frequency for erhu vibrato?

The concept of the correct frequency selection application is currently quite vague in the industry. Very random and unclear, each performance of a certain note is largely different. Euphemistically called this time, the mood, mood, etc. are not good, resulting in such a performance effect. This is due to a serious lack of understanding of erhu rubbing frequency, and there is no correct rubbing frequency concept for a certain note in my heart.

The importance of frequency is not technically known.

Here we mainly discuss the mimeto vibrato, so it is inseparable from knowing the principle of singing vibrato. A whole note 5—four beats, for example. In addition to the national singing method, the first one or half a beat is not expressed in vibrato, and the other three beats or three and a half beats must be expressed in vibrato. (Bel Canto or violin mostly use the first vibrato and the first vibrato.) The so-called late vibrato is to start a beat or half a beat without vibrating the strings. According to the principle of singing imitation, how should this whole note 5-1- be expressed?

National singing method: 123.1234.1234.123 The tail must have an air port to connect the above, so there is only three-frequency vibrato.

Bel Canto is different: 1234.1234.1234.123. This is the vibrato frequency of the singer.

We can only produce beautiful vibrato frequencies if we have a clear understanding of the singer's beautiful vibrato frequency. The frequency of the mimetic vibrato is to perfectly follow the singer's wonderful tremolo frequency, so the erhu mimetic vibrato is the pursuit of this digital standard and clear vibrato frequency.

Frequency is one of the most important factors in the three elements of mimetic vibrato.

2. Strength

The strength factor of erhu vibrato is also a very important factor.

There is no dynamic factor in the violin. Because of the different vibration modes of the material structure and the violin has a fingerboard, there is no dynamic factor. The erhu is not the case. If the erhu string is suspended in the air, you don't need to press the string with appropriate force (too big or too small). If it is too loud, the singing turns into a weeping sound. (At present, most of our erhu vibrato is like this. The performer is using vibrato to press the strings blindly in order to show himself.) In fact, it does the opposite and seriously destroys the emotion of the song. Let the notes rubbed suddenly change, but I don't know that this is not singing, praising, praising... singing of beautiful love, great motherland... etc. It sounds like blood and tears. Is this the correct performance of the erhu vibrato? Too little pressure, too bland, not lyrical, and not expressive. It's better for the former to press the words, blood, and tears than the latter, at least it doesn't destroy the emotion of praise and praise.

Therefore, the issue of strength is a major subject that everyone in the erhu performer must study.

3. Amplitude

Compared with the violin, the amplitude of the erhu vibrato is a short term, that is, it is lacking.

Due to the structure of the violin fingerboard, it has an extremely good performance in the control of the amplitude, which is the patent of its beautiful lyricism, especially the large back of the violin is very expressive, it can make the note to be expressed at #5 fluctuate between drops.

So far, Erhu Xianxian has not been able to do it at all, and it is far from being possible. Since the development of Erhu art, no matter what kind of kneading string such as: digging, pressing, rolling, pad finger kneading (multi-finger combined finger movement, sliding and kneading can increase the range, but add strength and cannot slide) theoretically, they are pursuing a good range. , but this high-level control technology for amplitude is completely unavailable in erhu technology.

After decades of artistic practice, the author has perfectly solved this unsolved problem. Inspired by acrobats walking a soft tightrope, he invented the method of erhu frequency division imitation vibrato. The imitation effect is excellent. So the name (Erhu imitation vibrato method) is: imitation vibrato.
