Buying erhu is mainly to look at the python skin, wood material and diameter and shape of the piano barrel. Looking at python skin is the most important part of buying erhu. Look at the python skin, mainly to see the size of the scales and whether they are uniform. Generally speaking, high-grade erhu or python skin scales of good erhu are larger and more uniform.

The size of the scale flower is basically proportional to the price of the erhu; the erhu with the larger scale flower is generally matched with better wood materials. In addition, when looking at the python skin, you should also pay attention to its thickness. You can see whether the thickness of the python skin is even when facing the sun (you can use more erhus to compare). Good python skin is moderately thick, with less burrs, and the skin surface is smooth and oily. The elasticity of the python skin is related to the sound quality of the erhu. When buying an erhu, you should also pay attention to the elasticity of the python skin. The python skin should not be too loose or too tight.

Generally speaking, the sound quality of erhu skin tends to be thicker than that of erhu skin, but the skin of erhu will gradually loosen over time, so do not buy erhu with too loose skin, and consider the future changes of erhu skin. Note here: some people buy erhu, just listen to the sound, thinking that the sound is thicker. In fact, the thin or loose skin of the erhu python produces a thicker sound. However, over time, such erhu may become dull and lose the timbre that erhu should have.
