First of all, I would like to explain to you that what we generally refer to as "tuning (tuning)" refers to tuning according to international standards.

Standard tuning of the erhu:

The outer string is a1, notation 6, singing la, corresponding to the 29th white key of the piano

The inner string is d1, notation 2, singing re, corresponding to the 25th white key of the piano

If you don't get the tune and strings right before practice, the following problems will occur:

1. The tone you set (or the tone you start with) is higher than the standard tone, then when you pull to the high-pitched area of the song, it is likely to reach or even exceed the highest tone of the range that the erhu can express (the theoretical range of the erhu). It is four octaves, usually played within three octaves, and it is difficult to pull up to four octaves), and playing the high-pitched region of the tone is also more demanding on the player, and amateurs usually cannot grasp it well , often when the high pitch is pulled, there will be noise or even whistling.

2. The tone you set (or the tone you start with) is lower than the standard tone, then similarly if you pull it to the bass region, the same problem will occur. That's why each piece has a key, and the piano needs to be tuned to standard before playing.

At the end of this paragraph, a comparison chart of the sound range of each musical instrument is attached (the picture comes from the Internet). You can take a look, no need to study

After knowing the importance of erhu tuning, let's return to the topic of this article, how to tune it?

The first is to use an electronic tuner

Adjust to the twelve equal temperament, when your inner and outer strings are in tune, the pointer will point to 0 in the middle (some tuners will light up green light), at this time the outer string is la and the inner string is re, which is the standard tone.

Secondly, if you don't have an electronic tuner, you can download a tuning software on your mobile phone. Whether it is an Android phone or an Apple phone, there is a corresponding electronic tuner in the application market. In the case of a tuner, it's still okay to be a reference.
