When it comes to loading and unloading erhu strings, it can be said that everyone can operate it. However, not everyone's method is correct, so what is the correct procedure for loading and unloading piano bridges?
The steps to install the Erhu piano correctly
The first method: first place the erhu on the root of the left thigh.
For example, in the playing position, the piano bar rests lightly on the left shoulder, the index finger, middle finger, and the outer edge of the violin skin without the clear finger, and the left thumb is used to lift the erhu strings to a height equal to or slightly greater than the height of the erhu yard. Align the string groove of the Erhu Qin with the strings, push and pull from the front to the middle to the center of the piano skin to the range of 0.5 mm above, and find the best resonance point position by yourself (increase the amplitude, feel comfortable, and the hair of the piano does not bounce when touching the strings. The sound is obviously increased, the sound in the sound area is brighter, the overtone at the half of the effective chord length is bright as a fifth, and the overtone at the lower quarter-place is bright as a fifth), Panasonic left thumb, install the sound pad, Complete the installation of Erhu Qin code.
The second method: first lay the erhu piano horizontally, with the piano bar facing forward and the piano skin facing upward, clamp the drum with both thighs, use the middle finger and the outer side of the erhu against the root of the piano bar, use the index finger to construct the strings, 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.
The steps to remove the Erhu piano correctly
First remove the sound pad, the posture of removing the bridge is the same as the installation, just lift the strings and then remove the bridge.
3. Damages easily caused by incorrect loading and unloading methods of Erhu strings
The use of strong pull and hard plugs often means that the erhu strings are not lifted from the bottom to the top before the saddle is loaded and unloaded, because in this state: - It is easy to cause the saddle base to strain the piano skin, especially when unloading It is more dangerous to use the unmoved bridge for a long time. The rosin powder becomes sticky when it comes into contact with the moist air, and it is easy to form the adhesion between the base and the piano skin. At this time, the bridge is pulled hard, and the movement of the piano is in the opposite direction to the scales of the piano skin, which is very easy. Bring up or tear the scales of the piano skin, causing 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. .
