Introduction course of guzheng vibrato

Guzheng vibrato introductory course, if you want to learn horn instruments, you need to lay a good foundation. Among all musical instruments, guzheng is highly recognized. Many people will give priority to guzheng when choosing musical instruments. So I'd like to share with you an introductory course, Tik Tok.

Introduction course of guzheng vibrato 1 understand vibrato.

To master the skills of vibrato, you must be familiar with what vibrato is. Vibrato is also a string rubbing. It is formed by the rapid alternation of local sounds and neighboring sounds. When playing, the right hand plays the local sound first, and the left hand presses the string and then plays the string. Press-play two or three times, and many times, depending on the score. There are also light earthquakes and heavy earthquakes. Teacher Guzheng will mark you with a pen.

Cognitive symbol

First of all, you should know the symbol of vibrato, which is marked above the tone you want to play. It is a wave symbol in China's book.

Play with your right hand first.

When you see a vibrato on the phonetic symbol in the book, you should first pull the string with your right hand, and the right hand is also with three fingers together. The middle finger plays the sound with a little force, and the left hand vibrates immediately. Don't wait for the right hand to stop vibrating, but as soon as the right hand is released, the left hand immediately catches the vibrato, which is actually the reverberation of the right hand.

The left hand trembled up and down.

Put on the fake nails, put the notebook in order, and put the third finger of the left hand on the string section about 15 cm to the left of the Zheng code. The index finger, middle finger, ring finger and middle finger are slightly hard, and the three fingers are naturally close together, waiting for the right hand to pull the string. As soon as the right hand leaves the string, the left hand starts to press. Relax your shoulders and don't make your whole body nervous. More importantly, the guzheng is beautiful in appearance.

Generally, you only need to press the middle finger in the primary practice, that is, the middle finger is exerting force, and then you learn to double vibrato and press two fingers (index finger and middle finger) at the same time. Play evenly to make the whole piece perfect.

Find out the score of the exercise

Generally speaking, it is from books, and the practice of guzheng vibrato is generally practiced with the soundtrack of "Beijing Jinshan Shang". Sing the score well by watching the beat of the score first, memorize what the vibrato is, and then pop it up naturally when it is needed. Be sure to learn music well.

Keep practicing

Maybe I'm not a music major. I spent two days practicing vibrato. Of course, I don't study as a student, but also as an amateur, so I keep practicing. At that time, my left hand was soaked. Although I want to relax, it's easier said than done, and my fingers hurt, because the guzheng is played with the meat at the fingertips of my fingers. When playing vibrato, I was particularly nervous at first, and my strength was uneven. At that time, the middle finger was blistered, but I was still not afraid. I kept practicing and finally learned.

Guzheng vibrato introductory course 2 Guzheng vibrato practice method 1. Angle:

As we all know, the angle at which the guzheng armor touches the strings directly affects the sound quality and timbre. It is generally believed that the direction of the plucked string and the plane of the zither string form an included angle of about 45 degrees downward, and the plucked string forms an included angle of about 45 degrees upward. However, the actual situation is much more complicated: the downward angle of 45 degrees of the clamping method is mainly for grasping, wiping and hooking three fingers, while the rebound fingering method is usually upward.

Due to the limitation of hand shape, the thumb nail in the formulation is generally inclined, so the actual chord supporting direction is inclined from front to right (as far as the right hand is concerned, the same below), which makes an angle of 45 degrees with the plane of the Zheng and 45 degrees with the longitudinal plane to the right and front. Otherwise, if you don't have the latter angle and just play directly in front of you, the timbre will be hard and not soft enough, which is not convenient for fast playing.

The correct direction of hooking, wiping and hitting the middle finger, index finger and ring finger is inclined to the right, backward and upward, making an upward angle of 45 degrees with the plane and an angle of about 30 degrees with the longitudinal section. In the finger-shaking method, the angle of nail string rubbing can be divided into two situations: index finger shaking and longitudinal cutting (which can also be regarded as an angle of about 30 degrees from left to right, front to back), and the thumb shaking and Qianyue Mountain form an angle of less than 30 degrees.

Practice method of guzheng vibrato II. Depth:

The point pressure sliding of the left hand and the depth of the right hand should be determined according to the requirements of different skills and the needs of the music. Generally speaking, the strings should be rubbed shallowly, and the pitch of the original sound should not be obviously changed. However, for music with strong style in some places, when it is necessary to produce loud sound waves (singing and rubbing) or slight nervous tremor (vibration), the left hand should rub the strings to a certain depth (sometimes to the depth of the previous pitch).

When playing press and slide, we should pay attention to the accurate press depth, which involves the interval problem. The zither is set with different rhythms, and the interval size of each tone is also different: the chord is set with five rhythms (trisection), the second interval is 204 minutes, and the second interval is 90 minutes (ancient semitone). There are big notes and small notes in the second grade of pure melody, 1 ~ 2, 4 ~ 5 and 6 ~ 7 belong to big notes, accounting for 204 points; 2 ~ 3 and 5 ~ 6 belong to small whole tones, 182 points; The second degree interval is greater than five degrees, which is 1 12 (ancient semitone).

Therefore, the left-hand pressing depth of the two laws is strictly different when pressing and sliding. In basic training, how to master the accuracy of sliding sound is particularly important. The specific essentials should be made clear to the students. After sliding the strings to the next level of pitch, they can be compared with the adjacent local sounds of the next level until the pitches are equal.

Method 3 of guzheng vibrato practice. Length:

Generally speaking, the appropriate distance (length) between the position of the left glide and the Zheng code is about 15 ~ 16 cm. Of course, this position is not absolute and can be adjusted according to the tightness of the copper string, the size of the code and the needs of music expression: if the string is tight, the hand can move slightly to the left when it is difficult to press the string; When the positive code (especially the small code in the high-pitched area) is low, you can move your hand slightly to the right to ensure the pitch is in place (especially the three-degree slide).

The distance between the right-hand plucking point and the front beam should be about 2 ~ 3 cm for beginners. The artistic conception of music often has different meanings to timbre, such as combining rigidity with softness, clear light and shade, clarity and so on, which requires players to choose different positions to play the strings to enrich their expressive force. Generally speaking, the closer to the front beam, the brighter the pronunciation and the tougher the sound quality; The closer to the center, the darker the timbre and the softer the sound quality. Sometimes you need to change the position and play left and right to change the timbre.

Method 4 of guzheng vibrato practice. Radian:

When playing the glide, especially the glide and the glide, the pressing and releasing process of the left hand should not be a simple straight line, but a curved curve, otherwise the glide is not soft enough; When sliding down, the finger should be pressed to the upper pitch first, then retreated to the lower part and put back upward, showing a low shape; On the last slide, press your finger forward to the next pitch.

Then step back, take an arc and put it back in a low shape; The next time you slide, press your finger down to the next pitch, then up, and then forward to the next pitch, showing a low shape. The sliding sound played by this fingerline has a full and complete passing sound and a beautiful rhyme, especially when the speed is slow, the effect is the best.

When playing the calendar, the lines drawn by the left and right hands should also be curved: the calendar with both hands can be hyperbolic ●●; One-handed calendars can be used for various curved shapes, such as ● shape, ● shape, ● shape, ● shape, etc. When you add flowers, you should shape them. In this way, your hands can move gracefully and freely, making the sound of beads falling from the plate, like rivers and streams.

Guzheng vibrato practice method V. Density:

The density of finger shaking directly affects the effect of finger shaking. Generally speaking, the density of thumb shaking is four to six times per second, that is, 8 ~ 12 times per second; The index finger shakes more finely, and it can shake 10 ~ 16 times per second. In basic training, first, we should emphasize relaxation, mainly because the wrist should not be stiff; Second, the armor should touch the string lightly and move back and forth at a uniform speed.

The density of the left-handed string determines the frequency of sound waves, which is directly related to the timbre: the natural gravity and rebound force of the palm fingers rub out the finest sound waves; Its frequency can reach 7 ~ 8 Hz, and it has a gentle sense of vibrato, so some people call it "vibrating string"; With the elbow joint as the axis, the natural gravity of the arm moves up and down and the tendon vibrates, resulting in loose sound wave density.

Its frequency is generally 5 ~ 6 Hz, which has a slightly intense feeling. Some people call it "snapping". Taking the wrist joint as the axis, the sound wave produced by organic kneading with fingers and elbow joints is the largest, with a frequency of only 3 ~ 4 Hz, which has a mellow and soft sense of ups and downs and can be freely changed. Some people call it "singing strings". What density of kneading method to choose depends on the music style and emotional needs, whether it is vibrato or chanting, dense or sparse, full of changes.

Introduction course of guzheng vibrato 3 i. vibrato

Among many techniques of left-handed rhyme, vibrato is a very important one. It expresses music through rapid and meticulous pitch fluctuation. "Trembling" is the general term of traditional "rubbing and reading" techniques.

Traditional "kneading" and "singing" are that the left hand is about 15cm to the left of the Zheng code, and the fingers of food, middle and nameless are aligned, slightly curved and gently attached to the string played by the right hand. When the right hand plays the string, the left hand makes vertical ups and downs on the string, so that the sound popped up by the right hand has regular ups and downs.

Fluctuations are always carried out regularly and repeatedly according to "accuracy" (the pitch of the string itself) and "height" (the left hand presses down, the tension of the string changes, and the pitch of the string sounds rises). Traditional "softness" and "sound" are only distinguished by the fluctuation range of chords, with the big one being "softness" and the small one being "sound". The general function of "kneading" and "chanting" is to polish the sound played by the right hand and prolong the sound waves, so as to achieve the embodiment of musical style and the expression of musical content. Judging from their nature and methods, they all belong to the same category, and there is no need to divide them into two types of techniques because of the fluctuation range of pressing.

Second, the type of "vibrato"

The classification of "vibrato" can be divided into light and heavy in chord intensity, continuous and rhythm in time and rhythm, and various "vibrato" that combine light and heavy and slide up and down. Here are several commonly used "vibrato":

1, "light vibrato" (~ ~) (also known as "flat vibrato", "ordinary vibrato", "ordinary vibrato" and "micro vibrato").

"Light vibrato" refers to that after the right hand plays the string, the left hand is placed on the string node about #% cm to the left of the Zheng code, and it is quickly pressed vertically up and down with the fingers of food, middle and nameless. There are no obvious sound points, and the interval changes no more than two degrees, which is as decorative as microwave ripples. This kind of "vibrato" is often used in light, elegant and slow melodies. This vibrato is the most widely used.

2. "Small vibrato" (the symbol is the same as "light vibrato", also known as "dense vibrato", "fine vibrato" and "broken vibrato").

The left-hand pressing method of "small vibrato" is the same as that of "light vibrato", but different from "light vibrato" is that the vibrato has a small amplitude and a large frequency, and is often used to press the tone (Fa, Si or other pressing tones). This kind of "vibrato" is often used in the melody of grief and indignation.

3. "Heavy vibrato" (≈≈) (also known as "big vibrato").

"Trembling" means that after the right hand plays the string, the left hand is placed on the string section about #% cm on the left side of the Zheng code, and the food, middle finger and ring finger are used for vertical and slow ups and downs. It has obvious sound points, and the interval changes generally in two or three degrees. On the basis of "small vibrato", it increases the amplitude of vibrato and the tension of chord. This kind of "vibrato" is often used to strengthen or expand the melody with strong emotions. With the change of musical emotion, "heavy vibrato" often appears in various combinations of fast and light, slow and light, fast and heavy, slow and heavy.

4. "Continuous vibrato" (the symbol is the same as "light vibrato")

The left-handed method of "continuous vibrato" is the same as before, but the difference is that the left hand is always on the main chord played by the right hand, so that the main tone of the melody is not limited by the gap between its transmitted sounds, and the sound wave will continue. This vibrato is often used in excited, happy or nervous and lingering melodies.

5. "Rhythmic vibrato" (the symbol is the same as "light vibrato", also known as "rhythmic vibrato").

"Rhythmic vibrato" is pressed by the left hand as before, but the difference is that the vibration of the left hand is carried out rhythmically. This vibrato emphasizes and prolongs the rhythm of chords, and is often used in subtle and deep melodies.

6. "Press quiver" and "Slip quiver" (~ ~, ~ ~ oblique display) (also called "flutter", "walk quiver" and "wander quiver").

"Pressing vibrato" means pressing the tone with your left hand and adding a vibrating action.

"Slipping" means that the left hand adds a vibrating action while making up and down sounds.

The combination of the above two "vibrato" and other techniques can not only fully express the intense emotions and sad feelings of music, but also fully reflect the local style of music.

Third, the general law of the use of "vibrato"

1. Generally, "vibrato" should be added in the following three situations:

(1) Duration (beat) plus "vibrato";

② Add "vibrato" to the sound on the remake;

③ Add "vibrato" to the voice of the right thumb.

The above three situations cannot be understood in isolation. We should deal with them dialectically according to phrases and emotions, and use "vibrato" reasonably and appropriately.

2. "vibrato" is an important means to reflect the local style, so when playing local style music, we should pay attention to the use of "vibrato":

① The style of northern Zheng music is rough, vigorous and lively, and more "heavy vibrato" and "small vibrato" are used for a long time;

② Nanzheng's music style is soft, euphemistic and elegant, using smooth and slow "light vibrato".
