The method of correcting intonation The intonation is not only the basic requirement of erhu performance, but also the basic requirement of all musical instruments. Since the erhu does not have a fingerboard, the string tension is relatively large, and due to factors such as the expansion and contraction of the hand shape and finger spacing when changing the handle, it may affect the intonation. In order to establish a solid concept of intonation at the beginning stage, some basic correction methods must be learned and mastered. Although these methods vary from person to person and have different characteristics, they generally have the following common points for reference:

1. Train your intonation through a combination of watching, listening, and correcting.

"Looking" is to visually observe the position of the fingers and the change of the finger distance, so that each handle can form a relatively stable hand shape and finger distance.

"Listening" is the precursor to seeing. Beginners can use the piano and other instruments to carefully judge the relationship between different intervals and finger distances. Adjust the pitch in time and develop good listening habits.

"Calibration" is to constantly consolidate the correct pitch and hand shape by looking and listening, while correcting the wrong pitch and hand shape.

2. Practice intonation through sight-singing and tracing. Sight-singing refers to singing the scores before practice; imitation refers to playing with bare hands, or imitating exercises with the help of other objects, to cultivate the ability of psychological sound.

3. Intonation training by keeping fingers.

4. Correction by using the unison conversion of the open strings and the four fingers.

5. Correction by converting open strings to overtones.

6. Pitch correction by finger spacing of fifths and octaves.

7. Intonation training through the training method of scales and arpeggios.

8. Auxiliary training is carried out by the medium tone (over tone) in the process of changing the handle.

9. The intonation is trained by the method of "fixed finger sliding" (that is, in a fixed position, by sliding finger pressing instead of changing the handle).

10. Temporarily make jump-type connections by using open strings to get into intonation.
