This time, we will talk about the specific movements of erhu pressing exercises, which can be intuitively felt by means of pictures and texts. The reason why the erhu phoneme stick is used to illustrate the movements is because it will look more clear.

Since the strings of the erhu are suspended in the air, the first is to pursue the accuracy of the pressing finger; the second is to control the weight of the pressing finger. Simulate the finger movements on the erhu to reflect the requirements of these two aspects (for the convenience of everyone's viewing, we use the erhu phoneme stick to illustrate). For specific exercises, pay attention to the following points:

The left hand must have the correct posture, hand shape, finger shape, the fourth or fifth degree frame of the left hand, etc. For related content, please refer to the articles I wrote such as "Erhu Left Hand Holding the Piano".

To make the finger end of the finger correctly press the center of the hole on the erhu qin post picture, avoid the movement of the finger in the front, back, left and right directions.

When pressing the finger on the erhu, the main force of the finger dropping comes from the root joint of the finger. The strength of each joint is concentrated on the fingertips, avoiding hard pressing, hard hitting and virtual pressing. The knuckles should be agile, flexible, and flexible. Except for the pressing finger, there should be a certain amount of pressure, and other fingers (including the retaining finger) should be relaxed. Also note that the finger lift should also be quick and springy. (Note: If the little finger is short and small, the little finger can be in a straight state), you should practice more finger-dropping movements of the little finger.

When practicing finger pressing, any finger pressing finger should have the ability to move independently, and other fingers cannot be affected by the falling, lifting and movement of a finger, which affects the accuracy of pressing finger by other fingers.

Erhu and one finger pressing exercises

The index finger of the erhu is one of the basic fingerings of the left hand, and it is very important. The precautions for simulating exercises on the erhu have been mentioned before, and here are two points to be emphasized:

. The lower arm of the left hand and the erhu piano column form an angle of about 45 degrees. With the wrist slightly convex, press the finger end (the pad part) of the index finger.

.When the index finger is pressed, the other fingers should not be raised too high. Whether the thumb is upturned depends on the person, but it is better to be upturned, which is good for the little finger.

The first finger of the index finger

The picture above shows the practice of finger pressing on the outer string of the first index finger. Due to the positioning function of the hole positions in the Erhu diagram, its position corresponds to the corresponding phoneme on the real piano. As shown in the picture above, if it is in the key of D, the index finger should be on the "6" sound; if it is in the key of G, it should be on the "3" sound... Beginners don't have to worry about finding the right phoneme.

Press the index finger back (major second degree)

The picture above shows the finger-pressing exercise with the index finger in the second position on the F key external string. When practicing, the index finger should quickly and elastically press the hole position of "4" (the index finger should clearly touch the side extension of the hole position on the erhu sound bar), so as to ensure that no portamento and virtual sound appear when playing on the real piano. (not full tone). When the index finger is tilted back, pay attention to the distance between the fingers, and try to reduce the distance that the 2-3-4 fingers are pulled upwards, and strive to maintain and stabilize the hand shape.

This technique of moving the index finger back by a major second is applied in the second position on the outer strings of F major and the inner and outer strings of B flat, E flat, and A flat majors. Since it is a major second interval, it is generally not allowed to have portamento on the real piano (note the difference from the minor second in the picture below).

There are two situations when practicing:

. When pressing the two sounds of "54", the index finger should be moved from "5" to "4". This exercise is no different from the "finger-moving exercise" in the "Special Exercise" column. As long as possible on the real piano as far as possible not to appear portamento as a principle.

.When pressing the three tones "564", as shown above. At this time, when pressing "6", place the index finger above the "4" sound in advance, and then complete the action of pressing the finger. This technique is a "prepared" finger-pressing movement (the index finger has a slight off-string movement), and the purpose of the exercise is to make the index finger lean back in place correctly. If the index finger can be tilted back in place correctly, the movement of the index finger off the string should be canceled.

Press the index finger back (minor second degree)

The picture above shows the practice of pressing the inner string of the index finger in the second position of F key. This method of moving the index finger back by a small second and pressing the finger is fully applied in the second position on the inner and outer strings of the F major and the inner and outer strings of the C major. Please refer to the diagram above for the practice points.

Note: The above picture is the change of the minor second interval.

Erhu and two finger pressing exercises

The middle finger is the thickest of the four fingers, and its strength is the strongest, so its practice should be based on the distance control between the middle finger and the index finger. No matter how thick or thin your fingers are, training with erhu phonemic sticks can give you a good grasp of intervals.

Middle finger small second

The picture above shows the 1-2 fingers between the fingers (the index finger is reserved, and the practice of 2-finger pressing is the main method) of the semitone finger. In the first position, such as the outer strings of G major (5.2) and C major (26 strings), the two fingers of the inner and outer strings are all in this finger shape, at this time the distance between the middle finger and the index finger is a semitone relation (minor second). In the low position, the erhu's fingers are wider, so it is not difficult to practice semitones with 1-2 fingers.

Middle finger big second

In the first position, such as the inner and outer strings of D major (15 strings) and the inner strings of G major (), the two fingers are all in this way. The diagram above can be applied to the middle finger of the outer string of D major.

Middle finger stretch and press (take D as an example)

The picture above shows the D key (1 5 strings) stretching and pressing the fingers on the outer string of the second finger. When practicing, after the middle finger is stretched in place, press the finger correctly (the middle finger should elastically and fully touch the four peripheries of the "" hole). When practicing on the real piano, it can be practiced in combination with the techniques of "moving fingers" and "sliding fingers".

When practicing with small hands, it is not necessary to keep the index finger on the phoneme of "6".

The difference between "moving fingers" and "sliding fingers" is that there is no portamento when "moving fingers", while "sliding fingers" makes people hear the presence of portamento.

Erhu three finger pressing exercises

In addition to the common major and minor second-degree clicks, three-finger pressing often encounters major and minor third-degree clicks, as well as finger-moving and sliding finger-pressing. The following are the simulation exercises of the ring finger major and minor third finger pressing:

The index and ring fingers are the major third

The above picture is the finger of the major third between the fingers 1-3 (take the finger of the external string of E major as an example). The index finger should be kept when practicing the big and small three-degree pressing of the ring finger.

Note: The pressing of the minor third is similar to the pressing of the major third.

F ring finger shift or slide

The picture above shows a typical ring finger stretched and pressed, that is, the ring finger moves a minor third. The difference between "moving fingers" and "sliding fingers" is that there is no portamento when "moving fingers", while "sliding fingers" makes people hear the presence of portamento. The same below.

Note: You can also keep the index finger on the "5" sound during practice, but the difficulty of the practice will increase.

D ring finger shift or slide finger press

The above picture is also a common method of extending and pressing the ring finger of the outer string of the D key. The ring finger in the picture also moves the minor third interval.

Erhu four-finger pressing exercise

Erhu's fingers are very wide when the erhu is in the low position, so when practicing on the real piano, because the little finger has the worst strength, sensitivity and independence, and the little finger cannot stretch when pressing the strings, it lacks elasticity, so the little finger is often pressed. Low and virtual sound phenomenon. The following exercises are very effective for improving the independence and flexibility of the little finger.

little finger contraction exercises

The picture above shows the practice of contracting the little finger on the outer string while retaining 123 fingers in the key of G. In the picture, when the little finger is close to the ring finger, the sound is actually a temporary sound (it can be regarded as the #5 or b6 sound). Practice notes:

.When the little finger presses the finger, it is necessary to maintain the arc shape of each joint, especially the joint in the middle of the little finger cannot be in a concave state. For those with shorter fingers, you can place the center of gravity on the ring finger, and the thumb can be moved down appropriately, but the practice time should not be too long. If the practice is still difficult, the palm and the erhu phonemic stick can be brought closer, and the tiger's mouth and thumb can also be moved down a little, but pay attention to restore it in time.

When practicing G major, it can be found that when the little finger is pressing the strings, the middle finger and the ring finger are easy to shift, and more practice can get a good improvement. You can practice G major on the basis of practicing D major.

Note: When playing in the low position, the 4-finger pressing of the inner string is often used instead of the open string sound of the outer string to change different timbres. Therefore, on the basis of practicing the little finger pressing of the outer string, it should be combined with the right-hand bowing method. The finger of the little finger of the string.

Little finger stretching exercises

The picture above shows the extension of the little finger of the F key external string (the second position), the little finger and the ring finger are in the state of the minor second, the major second, and the minor third. Practice notes:

. The tiger's mouth is relaxed, and the tiger's mouth should be kept stable during practice, that is, the tiger's mouth should not move down.

.Because the little finger is naturally short and small, when pressing the finger, the finger end of the little finger should be correctly pressed in the center of the hole of the erhu phoneme, and the end of the little finger should be elastically and fully contacted around the hole. in place. This can prevent the phenomenon of low-pitched sound on a real piano.

. Pay attention to the stability of the hand shape. When the little finger is extended downward, try to maintain the arc state of each joint of the little finger.

.Fingers should be reserved during practice, so that the effect of practice will be better. As shown in the above picture, the index finger and ring finger are kept on the corresponding phonemes.

Little finger stretch example exercises

The picture above shows the extension of the little finger in the key of D (the third position). The extension of the little finger and the ring finger is very common on the real piano.

The practice points are the same as above.
