The vocal characteristics of the erhu, the structure of the erhu and the vocalization method

Hehe, of course, all the sounds in the world are made by the vibration of objects. Erhu is no exception.

The sound of the erhu requires the harmony of all parts of the entire instrument.

1. First of all, there is the bow, which is made of a horsetail and a thin bamboo joint, and the horsetail is made with rosin;

2. Then rub and vibrate with the strings (rosin must be rubbed, because the ponytail and strings are very light, if you don't rub the rosin, it is not easy to make a sound);

3. Then transmit the vibration to the piano membrane (that is, python skin), barrel and rod through the piano saddle;

4. Cause resonance, so as to make sound.

The quality of the erhu timbre is also determined by various aspects, such as: the wood used to make the erhu, the age and toughness of the python skin, and whether the connection between the various parts of the erhu is good, etc., which is the most important. In addition, the material and texture of the saddle will also make some changes in the tone of the erhu.

The damping pad underneath the saddle has the effect of polishing the tone. Whether the ponytail of the bow is full and smooth also has a slight effect.

The violin vibrates by the strings to produce amplitude echoes in the speakers.

The same goes for the erhu, which is a characteristic of stringed instruments.

The flute is blown, the principle of air vibrating, this is the characteristic of wind instruments, and the harmonica is vibrating with reeds.

Cricket. Bees have vibrating wings.

Thunder is when the positive and negative charges of the clouds collide with each other, creating a short circuit, producing lightning and thunder.

The erhu is composed of the barrel, the skin, the stem, the headstock, the shaft, the jack, the horse, the bow and the strings, as well as the rosin and other accessories.

1. a piano barrel. The barrel is an important part of the erhu, which is pushed and pulled by the bow, and the strings are rubbed and vibrated to the consensus body of the piano skin. The texture and shape of the barrel have a direct impact on volume and sound quality.

It is generally made of rosewood or mahogany. The shape has hexagonal, octagonal, round, front octagonal and rear round, etc., and the commonly used is hexagonal.

2. Piano skin. The skin on the front mouth of the barrel is called the piano skin, also known as the piano membrane, which is an important equipment for the erhu to make sounds. The pervasive erhu is snakeskin, and the middle and high-level erhu are mostly python skin.

3. a stem. It is the pillar of the erhu and the trunk. It not only plays a supporting role in connecting up and down, but also has a certain influence on the vibration pronunciation of the whole body. Some of the materials used to make the stems are sandalwood, ebony or mahogany.

4. a piano shaft. There are a total of two feet of height and low loose fierce (alias qinzhen), which plays the role of adjusting the pitch, the upper shaft is bound to the inner string, and the lower shaft is tied to the outer string. There are two types of piano shafts: wooden shafts and mechanical shafts, both of which have their own advantages and disadvantages.

5. Bows and other parts.

It is an important tool for erhu pronunciation, which is composed of two parts: bow shaft and bow hair. The Gongling Bridge Pole is made of fine purple bamboo, and the thickness should be moderate. The stiffness and elasticity of the bow shaft will directly affect the outcome of the performance.

Construction: From top to bottom, it is composed of headstock, shaft, stem, string, jack, barrel, skin, sound window, saddle, sound pad, and stock, with a bow (bow shaft, bow hair) between the two strings.

Vocal method: The bow hair rubs against the string to produce vibration, and the violin code transmits the vibration of the string to the piano skin so that the piano vibrates (amplifies the volume) and the sound comes out of the barrel through the sound window.

Erhu, that is, the two-stringed huqin, also known as "Nanhu" and "Huzi", is one of the main bowed string instruments (rubbing string instruments) in the family of Chinese musical instruments. The timbre of the erhu is almost the same as the human voice, with a sense of singing and telling. Famous erhu songs include "Erquan Reflecting the Moon", "Good Night", "Listening to Song", "Horse Racing", "Grapes Are Ripe" and so on.

Precautions for the maintenance of musical instruments:

The maintenance of the erhu skin is very important for Hu Jing to maintain the tone of the erhu, and it is also the most important concern of every erhu player. If the erhu leather is well maintained, it will have a long lifespan.

Most of the common erhu with damaged skin is caused by improper storage and infrequent use. If the erhu is often used, its skin will maintain a certain elasticity, and the pronunciation quality of the erhu will be relatively stable. The timbre of the erhu is slowly pulled out in continuous use, and the regular use of the erhu is a good maintenance and maintenance of the erhu.

The timbre of the erhu has the characteristics of softness and lyricism, and the sound produced is very singing, like a human singing. The reason for this is that on the one hand, the pitch of the inner and outer strings and the tension of the strings are appropriate, and on the other hand, the side of the barrel is made of python skin. Therefore, it is possible to produce a calm and soft sound without pressing the strings and moving the bow with a lot of force during normal playing.

At the same time, due to the structural characteristics of the erhu and the characteristics of the python skin, the variability of the erhu timbre is caused. There are many factors that can change the timbre of the erhu, and a solid foundation is required.

Erhu: Started in the Tang Dynasty, called "Xiqin", has a history of more than 1,000 years. It is a traditional Chinese stringed instrument.

Erhu, also known as "Nanhu" and "Huzi", Erhu is one of the main bowed string instruments (rubbing string instruments) in the Chinese national musical instrument family.

Famous erhu songs include "Erquan Reflecting the Moon", "Good Night", "Listening to Song", "Horse Racing" and so on.
