How to Adjust the Tone of Erhu

The adjustment of erhu timbre is divided into two steps, the specific steps are as follows:

1, approximate tuning: A sound (440H) using a small group of standard pronunciation devices (pitch controller, whistle, re-tuning, etc.). ) As a standard sound, this is also the 5S sound in D key.

Then, according to my own judgment on the bottom of the outer string, by rotating the erhu (low or high or loose) on the outer string axis, the rotation range should not be too large, and at the same time, listening to the sound of the erhu, slowly adjust the outer string to the same pitch as the standard sound.

2. Fine-tuning: Select the mode of the electronic tuner as "erhu tuning mode", place it near the erhu drum, and then pull the slow longbow of the outer string with relatively uniform force, and observe the tuner while pulling the string.

Extended data:

Several factors affecting the pronunciation of erhu;

1. Bowing strength;

2. The external environment (quiet);

3. The weight line of erhu is aging (often manifested as the pitch difference between the empty string bow and the push bow, and the push bow is low).

Methods of mastering the intonation of erhu;

1, the tuning should be accurate: whether using traditional Andhadhun or electronic organ, the accuracy of the performer is very high. If you are not sure about the fixed pitch, especially for beginners, it is recommended to download special erhu tuning software on your mobile phone, and the accuracy of the software even exceeds the human ear.

2. Too much or too little finger distance change: because the tuning of erhu often changes the fingering of semitone; The semitone of G is between the first and second fingers of the outer string, but the inner string is between the second and third fingers. The semitone of F key is between three or four fingers, so we should strengthen the practice of mode scale according to the fingering of different keys, and pay attention to the change of finger distance of each key.

3, changing the handle is easy to run off: moving too much or not in place when changing the handle will cause inaccurate sound. To ensure the accuracy of changing the handle, players should have the concept of pitch after changing the handle.

4. Incorrect vibrato: When you are a beginner, because you can't master the unity of the amplitude, speed and weight of vibrato, it often causes the voice to drift. At this time, the amplitude, strength and speed of wrist and palm vibration should be controlled by auditory adjustment until the strings are kneaded to make a harmonious and pleasant sound.
