When it comes to loading and unloading erhu strings, it can be said that everyone can operate it. However, not all methods are correct and standardized. Because, the improper loading and unloading method of erhu qin code will cause undue damage to the skin of the erhu qin, or even cause irreversible damage, and secondly, it will cause damage to the erhu qin code. I would like to summarize the personal erhu code loading and unloading methods as follows:

1. The procedure to correctly install the Erhu piano code:

The first method: first stand the erhu on the root of the left thigh, such as playing the piano, the piano bar lightly rests on the left shoulder, the index finger, middle finger, and the outer edge of the piano skin, use the thumb of the left hand to push up the strings of the erhu. The height is equal to or slightly larger than the height of the erhu string, and then align the string groove of the Erhu string with the strings, push and pull from the front to the center of the piano skin to the range of 0.5 mm above, and find the best resonance point by yourself (with The amplitude is increased, the hand feel is comfortable, the bow hair does not rebound when touching the strings, the sound is obviously increased, the sound in the high-pitched area is brighter, the overtone at half the effective string length is bright as a fifth, and the overtone at the lower position is one-fourth. Bright as a fifth), Panasonic's left thumb, install the sound pad, and complete the installation of the Erhu piano code.

The second method: first place the erhu in a horizontal position, with the stem facing forward and the skin facing upwards, clamp the drum with both thighs, press the middle finger and the outer side of the erhu against the root of the stem, use the index finger to stretch the strings, and the stretched The height is equal to or slightly larger than the height of the Erhu qin. Then align the string groove of the Erhu Qin with the strings and place it in the center of the piano skin to a range of 0.5 mm above, and the others are the same as before.

2. The procedure to remove the Erhu Qin code correctly:

First remove the sound pad, the posture of removing the bridge is the same as the installation, just lift the strings and remove the bridge.

3. Damages easily caused by incorrect loading and unloading methods of erhu strings

The use of strong pulls and hard plugs often means that the strings are mounted and unloaded without lifting the erhu strings from bottom to top, because in this state: first, it is easy to use The saddle base will cause strain on the piano skin, especially if the saddle is removed and used for a long time, it is more dangerous. The rosin powder will become sticky when it comes into contact with the moist air, and it is easy to form adhesion between the base and the piano skin. At this time, pull the saddle rigidly. The movement direction of the piano code is in the opposite direction to that of the piano skin scales, which is very easy to lift or tear the piano skin scales, resulting in irreversible damage. Second, it is easy to damage the erhu bridge. The wood of the erhu bridge is generally very crisp, the strength is not high, and the shear resistance is lower.

Erhu piano code maintenance precautions

As long as the piano code is not damaged by humans, it is very durable. Good piano code is very rare. Once you have it, you should pay attention to the maintenance. The maintenance of the piano code should pay attention to the following aspects:

1. The string groove of the bridge is a relatively weak place, especially when the hardness of the bridge is not high, it is easy to be worn by the strings, so when loading and unloading the bridge, an appropriate method should be used to raise the strings before proceeding.

2. When cleaning the piano code, use a dry brush, a dry towel or a mostly dry towel, do not wash it with water or organic solvents such as alcohol, especially the old pine knot erhu piano code, which contains high pine resin, such as organic Solvent cleaning will destroy its structure and cause artificial damage to the piano code.

3. Do not expose to sunlight.

4. Keep it clean and dry when storing.

Anyone who studies Erhu knows that rosin is an essential auxiliary material for playing erhu. In modern erhu, rosin is applied to the bow to increase the friction of the bow hair, increase the friction on the strings, so that the erhu makes a normal sound, basically, if the rosin is not properly applied, the friction of the erhu bow on the strings is usually slippery and difficult to make a sound, so it can be said that the auxiliary material of rosin is crucial for the erhu.

Have you paid attention to the comparison and comparison of many songs specially made for Erhu, all erhu performance of the main melody is not lower than the inner empty string tone, just like G (Erhu from 3 to 7 are bass notation), the inner empty string is bass 5, how can play a lower than 5 note 3!
