Finger-pressing practice[7] 1=d 4/4 This is the first etude for almost every erhu beginner to use the left hand. When using the left hand for the first time, it is inevitable to be nervous. Pay attention to relax the arms, shoulders, and wrists. Arched, the thumb is relaxed, neither tilted nor grasped, the forefinger touches the string lightly, and the touch is decisive, and the touch time is the same as the bow change time. [8] 1=d 4/4 middle finger practice, the distance between the index finger and the daughter is roughly the same as the distance between the middle finger and the index finger, but the distance alone can not be completely accurate, you must pay attention to the sound of the enemy and the erhu. [9] 1=d 4/4 Ring finger practice, the ring finger generally lacks strength, often practice raising the ring finger, hit the string hard to make a sound, and gradually develop strength. Also pay attention to the minor second pitch.

D scale practice[10] 1=d 4/4 The first little finger practice, the little finger is the most difficult finger among the four fingers to practice. The inner string 5 and outer string 5 of the second bar and the twelfth bar must be the same pitch. [11] 1=d 4/4 After the eighth note appears, there is no way to use the longbow anymore, just use the middle half of the bow, and the focus is still on the inner and outer strings 5.

Practice of slurred bow[12] 1=d 2/4 Finally, the slurred bow appeared. From now on, it is no longer necessary to draw only one note per bow. The common problem of beginner slurred bows is that there are two slurred bows in the same bow. The lengths of the notes are different. As long as you practice slowly and use a long bow, you can solve it slowly. The second beat 5 of the penultimate measure must use the inner string, otherwise the following 4 will definitely disappear. Of course, you cannot change the string if it is not the same bow. , just because it is the first time to practice slurping, there is no need to make yourself so tired, changing the strings of the same bow will naturally be practiced in future string changing exercises.

[13] The practice of 1=d 4/4 bow segment, the four-beat full bow should be done with the feet, from the tip of the bow to the tip of the heel, without wasting at all. The first two rows of the second row and the fourth row The right half of the bow is used for all the bars, and the left half of the bow is used for the last two bars. It must be noted that the right half of the bow is easily pulled too hard, causing noises, while the left half of the bow is easy to be weak and the volume is too low. Velocity, so that the left and right half-bow volume timbres are the same.

[14] 1=d 2/4 This etude synthesizes all the things learned in the previous three pieces. The eighth note has both a continuous bow and a separate bow, a left half of the male and a right half of the bow. Usually, the cerebellum is trained here. I'm going to start getting confused, I have to think about which finger to use on my left hand, I have to think about even and split the bow, I think about my left hand and forget my right hand, and when I think about my right hand, I forget my left hand, haha, don't be nervous, it was the same in undefeated years, if I really can't practice it, so go back and practice the first three songs.

[15] Slow practice --> Speed up Usually, in the song, if the same bow can use the same string, try to use the same string, but it is inevitable that there will be times when the strings must be changed. Unlike the violin, the erhu can be tactfully changed when changing the strings. The erhu must not be very smooth when changing strings on the same bow. This is an inherent defect of the erhu. We just want to avoid too much gap when changing strings. In this etude, 26 36 64 62 41 31 21 The strings must be changed in the same bow. There are four directions when changing strings. Pull the inner string to change the outer string, pull the outer string to change the inner string, push the inner string to change the outer string, and push the outer string to change the inner string. , All four directions must be practiced well.

[16] Slow training --> Speeding up is also an exercise for the cerebellum. It is not a very common bowing technique, but it is a good practice. If you practice this kind of practice more, you will be able to adapt to the strange bowing technique in the song in the future. , the sixteenth note is also the first time to appear, 3212 should not be difficult to deal with, 5434 is more difficult, and the outer strings should be changed immediately after the end, which is a good test.

[17] Slow practice --> speed up a very good muscle etude, it is best to repeat it continuously, repeat until the little finger and ring finger start to feel sore, and then continue to practice, practice several times a day, the muscles of the little finger and the ring finger will grow up soon. The intonation of the huqin The problem of the intonation of the huqin is very complicated. Let me first write about what will affect the intonation of the huqin. The huqin is a very sensitive instrument, you can shake the stem back and forth, left and right when you move the bow, or increase and decrease the pressure with the left hand tab, you can hear the pitch change, and the pressure increases when you move the bow and decrease, bow and bow all affect pitch. In addition, the left hand shape and the method of pressing the strings more directly affect the pitch.
