The wheel finger is another important fingering in the right fingering, and there is hardly a song that does not use it. There are many fingerings composed of wheel fingers, such as belt wheel, sweep wheel, full wheel and so on. Bai Juyi's "Song of Everlasting Regret" described "big pearls and small pearls falling on a jade plate" is not an artistic exaggeration, but refers to the performance of the ring finger. When playing chords, the fingers of the wheel play a unique role.
Compared with other fingerings, wheel fingering is relatively difficult to practice because it has to overcome various physical limitations of our fingers. There are many people who give up the pipa, mostly because the wheel fingers are difficult to practice. Practicing the ring finger well is very important to express the connotation of a piece. Beginners should start practicing the ring finger as soon as they come into contact with the pipa.
In guitar playing, there are many techniques similar to the lute, one of which is the ring finger. It's just that the round fingers of the guitar are generally three-fingered rounds (that is, the food, middle, and ring fingers), and the little finger is added when the half round is used, and the "hook" is used. The thumb generally does not participate in the round, and is only used to play bass to obtain Harmony effect, so it is relatively easy to finger the guitar.
In the pipa round finger, the five fingers are used to touch the strings in turn, and there are five tones in total, and the five tones are required to have similar pronunciation and uniform rhythm. Our five fingers are different in length, thickness, width between the metacarpophalangeal joints, etc., and when touching the string, it is not like the usual way to hook the fingers inward, but to pop the fingers out one by one. , and the parts that touch the strings should be concentrated in the five cities. Therefore, it takes a certain amount of effort to practice the wheel fingers well.
A common problem with wheel fingers is that the pronunciation of each finger is uneven and discontinuous. Generally speaking, the sound of the big and index fingers is heavy, and the pronunciation of the middle and name, especially the little finger is light; there is discontinuity between the big finger and the index finger, and between the big and little fingers; the whole interval of the wheel is weak; the pronunciation of the wheel is accompanied by loud noise Wait.
Wheel fingers mainly rely on the joint movement of the fingers to make sounds. Our fingers are generally large, the index finger joints are thicker, and the strength is strong, while the middle, name, and little fingers are relatively thinner and weaker, especially the little finger. Therefore, the knuckles of the middle, name, and small fingers can be flexed and extended frequently to enhance the flexibility and strength of each knuckle. When the fingernails of the middle and small fingers are in contact with the string body, the horizontal angle should be smaller; when the string is played, each finger should press as much as possible in the direction of the panel.
The timing of the pronunciation of each finger is not uniform. The middle, name, and small three fingers play the strings faster and the volume is low. The middle, name, and small three fingers can be used at a very slow speed and strong volume to correct them too fast. Habit. The time between the thumb picking and the index finger playing this sound is longer than that between other fingers. Most of them can only use the index finger to start the wheel at the beginning of the wheel, so the method of thumb-up wheel can be used instead. For the phenomenon that the time between the big and little fingers is long, it is mostly because the thumb can only be used to lift the board, and the index finger can be used to lift the wheel instead.
The overall volume of the wheel is weak, mostly because the fingers are inflexible and have little power. Usually to strengthen the flexibility and strength of the fingers exercises. Each finger can be flexed and extended independently and frequently at any time to enhance the flexibility and strength of each finger joint. In the process of the wheel, pay attention to use the joints of each finger to move.
The pronunciation of the wheel is accompanied by a lot of noise, especially when the thumb is picked up. During practice, the movements of the two joints of the thumb are first practiced very flexible; secondly, the thumb is developed and rotated to the index finger, and then the string is picked. habit; then pay attention to the less time the thumb nail and the string body touch the string, the better, and the smaller the string contact area, the better.
All in all, in the practice of wheel fingers, special attention should be paid to the flexibility and strength of the fingers. At the beginning of practicing the wheel finger, you can recite the rhythm of "one, two, three and four" silently. At the beginning of each rhythm, you should replay it. Start practicing at a slow speed. When you practice to a certain level, your fingers will naturally speed up. done.
In order to strengthen the flexibility of the finger joints, simulation exercises can also be carried out when not practicing the piano. The methods are as follows:
Fix the wrist joint on the table, that is, the part where the base of the palm and the wrist joint are connected to the table (the back of the hand is upward), bend the hand to be practiced toward the palm, and then force the bent index finger forward. When doing the above-mentioned outstretching movement, the second and first finger joints must be forced to move and exert force. In order to achieve this purpose, when doing the extension movement, the nails are first pressed against the table top, and then the nails are extended forcefully.
