In addition to its expression and function, vibrato also has some unique and subtle special effects.

1. Fine-tune the pitch during performance

In the process of performing on the stage, there are many situations that we need to grasp temporarily. A dissonance caused by technology, a long tone that temporarily conflicts with the piano and the band, or the strings are out of tune, etc., all urgently need us. Make decisive adjustments. There is nothing more natural and effective than the fine-tuning of the vibrato, the nimbleness and subtlety that resolves the embarrassment in time and hides it before you know it. To have this ability requires a keen hearing and adaptability, and of course, the actual experience accumulated on the stage. In addition, it must be stated that this method should never be used in daily piano practice. When practicing the piano, we should fully and strictly deal with the disadvantages of playing, let alone cover it with vibrato because a certain note is not accurate.

2. It is a micro element that adjusts the tone

An excellent player is not only full of the desire to express music, but also better at conveying feelings through his own hands and adding the charm of timbre. This kind of fingertip movement born of emotion allows the vibrato to connect with the heart when the player is fully engaged in the music. When this kind of artistic conception appears, the performer will often describe the wonderful artistic conception of the vibrato to the timbre vividly and vividly through the needs of the soul!

3. It has a propelling effect on the change of note intensity

In some traditional music and works with strong local flavor, the range of dynamic expression is relatively large and exaggerated, which prompts the need to greatly enhance the expressive power of erhu. When all the performance techniques related to the dynamics are insufficient, some keen players will definitely use the left hand to vibrate the strings, that is, by increasing the amplitude and strength of the vibrating strings and speeding up the frequency to achieve the desired effect of the work. To produce this ideal change of force, the coordination of the right-hand bow speed is very important and critical.
