Getting a new erhu will make many piano friends very excited, but they will also have some troubles. Everything is new with the new piano, and they have no idea where to start. How to use a new erhu?

1. Take the sound:

1. The new piano needs to "take the sound", first pull the empty strings to disperse the sound, listen with your ears, think with your heart, how to play it well, set a good goal, and then adjust your own playing method. It is the same piano, and different playing methods will inevitably make the piano emit different timbres. A new qin is like a piece of white paper. Only by using the correct method can the original sound be gradually vibrated and the longer it will become more pure.

2. The skin and barrel need to vibrate regularly and with sufficient strength for a long time to expand and contract, so that it can be called a piano. Conversely, playing (pulling) the qin indiscriminately will exceed the limit of contraction and expansion of the qin itself, which will break the sound of the qin and crack the sound.

3. After the piano has been used for many years, its original sound has not been turned on, just like a new piano. This is caused by the user's playing method or insufficient force on the piano.

4. How to keep a good piano, the most critical problem is to take the sound and debug it. The correct method of taking the sound is the key to keeping the piano.

2. open the voice:

1. The new piano needs to be "opened", and the opened piano will be easy to play. There is a strange phenomenon in the process of opening the voice. When you use the correct method to pull it to a certain day (usually 3 to 5 months), the piano will suddenly emit a very obvious buzzing sound, and the aftertaste will also lengthen. Soft, in fact, the tension of the string has not changed at this time. After continuing to practice, the sound of the piano began to become more and more pure. When the regular vibration reaches the limit, the amplitude of the resonance box increases, and the phenomenon is that the volume suddenly increases. At this time, the piano is turned on. This is the result of the corresponding cooperation between man and the piano. If you don't pull your hand at this time, the original new sound will become worse soon.

2. If the force of playing the violin is too small or the method is incorrect, the violin will not automatically start to sound after being used for a long time. The thickness of the barrel (sound box) is set for the strength of the piano, and it is impossible to thin the barrel to pull out the sound. Due to the difference of materials, the opening voice also varies from person to person, and there will be sooner or later. However, after getting the new huqin, it is found that the skin is thick or hard and must not be oiled or Vaseline, because oil and Vaseline will penetrate into the python skin fibers and make the python skin lose its elasticity. The best way is to add a little beeswax, use a massage vibrating hammer along the edge of the piano skin, turn clockwise from the outside to the inside, and slowly press and knead one scale after another, and there will be a certain opening sound. Effect. What attracts special attention is that practicing huqin, the middle-grade huqin is easy to get started, and it will turn on as soon as the tone is pulled, which is not suitable for this method.

3. When someone has a bad piano sound, they will ask a master to help him get the good sound back, but after using it for a while, the sound of the piano gets worse again, that is, there is a problem with his own playing method.

4. Opening the voice is not the ultimate goal, it is just an introduction. Maintaining the timbre of the huqin is the ultimate goal. It is necessary to maintain continuous constant pulling and practice for a long time to protect the elasticity of the piano skin.

3. After getting the new piano, you should always observe the subtle changes, usually:

1. The new piano should check whether the sound groove and string groove are standardized, and whether the production process is fine.

2. After the new piano is turned on, observe whether the scales on the skin of the piano are lifted, and touch it with your hand to see if there is a little cut.

3. Whether the piano bar is vibrating, whether the tip of the hand model and the piano are vibrating, whether there is a vibrating feeling, and whether the croaking sound is obvious.

4. Whether the overtone in the third position is prominent, and whether there is a nasal child sound.

5. When the overtones in the first and second positions are very good, the maintenance of this huqin is basically in place.

6. Choose erhu accessories according to local conditions, such as jins, piano yards, strings, rosin and bows are all very important, and they should be run in reasonably so that you can play your huqin with ease.
