Learning the fingering of erhu has a history of more than 1000 years. It is a traditional stringed instrument in China. Many erhu techniques can find feelings from some related things, which is called "synaesthesia" in literary rhetoric. The following is the fingering of learning erhu.
Learn the fingering of erhu 1 1 When holding the erhu, the palm of your left hand clings to the piano rod, your fingers "lie down" and press the strings backwards, and your thumb bends downward to hook the piano rod.
2, finger joints are excessively bent, and fingertips (even nails) touch the strings.
3. Finger joints are upside down, especially the first joints of middle finger, ring finger and little finger.
4. Fingers (especially ring fingers and little fingers) do not press the strings from the front (from string to string), but from the outside (from string to piano body), so that only the outer strings are pressed, but the inner strings are in a virtual state, and wolf sounds often appear.
When a finger is pressed on the string, the finger under it is curled up in your palm. When playing, always let your fingers "hang" above the phoneme and you can't relax.
6. Precautions. In the process of using the piano bow, don't touch the bow hair with your hands, so as not to get oil stains on the bow hair for a long time and affect the performance. Once it is found that there is a lot of grease on the bow hair, which affects the performance, the bow can be removed, washed with soap in clear water, dried and re-rubbed with rosin before use. Every time you finish playing the piano, you should relax your bow.
Restore the bow rod to its normal shape, otherwise it will deform after a long time and affect the performance of the bow. If the bow doesn't need to be placed in the piano box for a long time, you can put some moth-proofing agents in the piano box to prevent the bow hair from being eaten by insects. In the daily use of erhu, it is not necessary to apply vegetable oil and vaseline to leather. And there is no need to seal the back of the leather with wax.
If the inner and outer surfaces of leather are coated with oily substances, it will affect the permeability and vibration of leather. After the lid is covered, the back of the lid cannot be treated, because scraping or polishing the back of the lid from the back of the bucket will lead to uneven thickness of the lid.
In severe cases, it will also lead to the rupture of the piano skin. To improve the timbre of erhu, measures should be taken from the aspects of string, bow, piano and control pad.
Learn the fingering of erhu 2 1 and press the strings of erhu.
When pressing strings, the hand shape should be relaxed, the fist is half clenched, the thumb is relaxed and naturally stretched, and the other four fingers are properly bent. When one finger presses the string, the other fingers should not be stiff or excessively bent, and be prepared to press the string alternately in a relaxed state. When the strings are pressed, all fingers touch the strings with fuller fingertips.
The fingers that press the strings should have a certain strength, but they should not be stiff, and the ups and downs should be elastic. It is easy for beginners to give too many thumbs up or hook the piano rod at the beginning of practice, so they should correct it at any time. In addition, we should use our eyes to measure the distance between the tiger's mouth and the thousand pounds, and use our ears to distinguish whether the sound is accurate or not.
2. The vibrato of erhu
Vibrato is also called playing the strings. The symbol (a) is often used in music. Generally speaking, its playing method is that when one finger presses the string, the adjacent fingers follow closely and quickly fluctuate on the string, forming a series of alternating, uniform and elastic sound effects. Tremolo is mostly a second vibrato, but it is sometimes used for special styles, such as Mongolian-style music works. When playing vibrato, your fingers should be active and agile, and your pronunciation should be clear and smooth.
3, erhu kneading strings
By pressing the strings, the fingers roll regularly at a certain phoneme, or a relaxed pressure is applied to produce uniform sound wave changes. This technique is to knead the strings. It is the most important expression of erhu techniques. There are three kinds of kneading strings: ① rolling kneading, ② pressing kneading and ③ sliding kneading.
The effect of rolling and kneading is that the fingers roll evenly on the strings and emit uniform sound waves around the local sound. This kind of string kneading sounds soft and smooth, full of singing sense, and is the most commonly used method in string kneading. When practicing, with the slight assistance of forearm, use your wrist to drive your palm.
Fingers roll on the string regularly and elastically. Unlike western stringed instruments such as violins, erhu has a fingerboard as the final support point of fingers, so when fingers roll, the tension of strings is obvious, and fingers also produce natural string pressing components. So rolling should actually be called rolling.
Pressing and kneading is a powerful method of kneading strings. Through the Zhang Chi action of fingers up and down, the strings are tightened by grip strength and have a sense of tension. When practicing, the forearm, wrist and palm all have the same tension, but don't be stiff.
Sliding kneading is a kind of string kneading method with large sound amplitude, which has local characteristics. Generally, it is used to play northern style music or imitate the singing of China traditional opera. Pay attention to the relaxation of upper arm, lower arm and tiger's mouth during practice.
4, erhu reservation refers to.
A finger that doesn't press the tone still stays on the string and doesn't lift, which is called a reserved finger. It increases the assurance of intonation and accelerates the playing of fast notes by reducing the number of finger undulations. Take 1 5 string as an example: for example, when four fingers press two four pentatones, one or two fingers can stay on the string. It not only keeps the phoneme of hand shape unchanged, but also increases the assistance of finger pressing, which is often used in erhu performance.
5. Erhu Slippery
The sound made by fingers consciously sliding on the strings is the sliding sound, which is one of the characteristics of bowstring instruments in China. It plays an important role in highlighting local style and decorating melody color in music. Because the sliding mode and position are different, the sliding effect is also different. There are many kinds of sliding sounds in erhu performance, which can be summarized into four types: up sliding sound, down sliding sound, back sliding sound and pad finger sliding sound.
Slide: refers to sliding from bass to treble. The slide in the third interval is a smaller slide up.
The decline beyond the third interval is a big top decline.
Glide: refers to sliding from high notes to low notes, and the glide in the third interval is a small glide.
A glide beyond the third interval is a big glide.
Slide backwards: There are also the last slide and the next slide. But last time, gliding was rarely used. The next way to play is to slide from the local voice to the' bass' within three degrees, and then slide back to the local voice.
Pad Finger Slip: The sliding effect caused by two or more fingers rolling up or down in turn is called pad finger slip. It is slightly more difficult than the above three sliding methods. Generally speaking, sliding sound is basically sliding from one sound to another with the same finger. As long as you pay attention to relaxation, it is not difficult to practice.
Learn the fingering of erhu 3 The benefits of children learning erhu
First, increase intelligence.
1. Music training in childhood has a significant effect on intellectual growth (experiments have proved that learning music at the same time is obviously helpful to academic performance)
2. Learn abstract concepts (music theory)
3, can improve mathematics and reasoning ability (scale and interval)
4, memory training (reading spectrum, memorizing spectrum)
5, concentrate (listening training)
Second, balanced development.
1, music can balance the development of the left and right brain (especially for the development of the right brain, children usually use their left hand less, while erhu uses their left hand to press strings, and their right hand skills are also very high, which is conducive to the coordination of the brain and limbs).
Music can make the body and mind develop in a balanced way.
Music can help children develop their personality.
Third, develop potential and stimulate creativity.
1. Music is the basic ability and emotional instinct of human beings. If properly inspired and guided, it can enrich children's future life.
2. Through the training of creation and arrangement, children's imagination and creativity can enter an untouched space.
Children's musical talent has the opportunity to sprout and thrive.
Fourth, cultivate temperament.
1, carefully selected high-quality music has a subtle influence on children's personality.
2. Music is the best emotional outlet.
Fifth, establish a good learning attitude.
Erhu playing skills pay attention to the unity of heart and hand, which will teach children to show patience and pursue a correct attitude.
Six, learning interpersonal relationships
1, group lessons lay the foundation for group learning, increase life fields and make more friends.
2. Demonstration and imitation among friends can achieve a good interactive learning effect.
3. Let children understand the importance of division of labor and grouping through training methods such as ensemble and division.
Children learning erhu can cultivate students' perseverance, attention and imagination, and improve their intelligence, especially their logical thinking ability. Erhuqu is the performing art of sound, and the expression of its notes contains infinite meaning, which provides infinite space for children's imagination, logical thinking ability and jump thinking. Children can interpret their music according to their own imagination, so learning erhu can improve all aspects of intelligence and brain ability.
