How to tune the erhu?

Erhu tuning 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:

1, erhu is generally tuned in a five-degree relationship, such as (d 1, a 1, g, d 1, a, e 1) or (e65438).

2. When playing some local music or opera, there is a pure four-degree relationship in addition to the five-degree relationship. Individual venues may even have octave chords.

3. The range of erhu reaches three octaves, but it rarely exceeds two and a half octaves in general music.

4. The timbre of erhu is flexible and delicate. Have rich expressive force. Suitable for playing all kinds of complex tones. Erhu can not only play a soft and smooth melody, but also play a jumping and powerful melody. He often plays the leading role in national bands and folk silk and bamboo bands.

Erhu is not only used for solo and ensemble, but also the main accompaniment instrument for local operas and rap music, such as Pingju Opera, Yue Opera, Shanghai Opera and Cantonese Opera. At the same time, erhu is also called "main Hu" or "home court".
