What is the difference between Zhonghu and Erhu? How to distinguish them? Today, I will do a simple analysis for you, I hope it can help you.

different piano bars

The erhu stem is 81 cm long and about 0.55 inches in diameter. The head of the erhu is in the shape of a curved neck, and some are also carved into a faucet or other shapes; Meniscus shape.

different strings

Erhu strings are thinner and the barrel is larger. When using silk strings, the outer strings use middle strings, the inner strings use old strings, and steel strings are often used. The length of the bow is 75 cm. Zhonghu strings are thicker than erhu strings and have a richer timbre. Zhonghu strings are one perfect fourth or fifth lower than that of erhu, and the range is more than two octaves.

The pose is different

In the sitting posture of erhu playing, the midline of the body is inclined to the left, so that the center of gravity falls to the left side of the human body. With your back straight, sit upright on one-third of the stool. There are three types of Zhonghu: flat-legged, framed-legged, and standing. Generally, the flat-leg style is adopted, that is, sitting on a stool or a chair with no support of the right height, the legs are naturally flat, the heels are naturally on the ground, the thigh and the calf are basically perpendicular to each other, the thigh forms a plane, and the piano tube is placed on the left leg.

different maintenance methods

Most of the erhu barrels and bars are made of hard woods such as red sandalwood, ebony, and mahogany, and hard woods are easily affected by the climate. When Zhonghu looks from the qin barrel, if the skin of the qin appears very dark, almost no light can pass through, then the skin is too thick. Too thick skin will affect the good vibration of the instrument, making the sound dull and woody, and the volume is low.
