Erhu started in the Tang Dynasty and has been a history of over 1,000 years. It first originated in the northern part of a minority group in ancient China, then called .Around Chen Ning generation of scholars in the "music" which documented "Hu fun ...... this" well in the Tang Dynasty poet contained "military home drink wine final customer, pipa and erhu .... "a poem that has begun to spread in the Tang Dynasty Music. China and the West is widening string instruments and trampoline promote music skies. The Song dynasty, will play the name of "Ji Qin." Chen Liang in the late scholar Song "Lin Guang Ji things," such as record : Kang Ji Ji Qin The system was named "Ji Qin." Shen Kuo in the Song Dynasty University of the "fill a pen and paper. Music and Rhythm, "reads :" Xining, the Palace banquet Jiaofang played Actors XU Yan Ji Chin A string side wine must and become more difficult to school, only one string and his song. "shows that the era of very high performance levels in the Northern Song Dynasty. XU Yan Emperor minister for a concert, "Ji Qin", continuously through a string, the string Zouwan still another song. No consummate artistry is not. Later Shen Kuo also recorded in the "Meng Xi Bi Tan," "Music With Han Dong Mawei. Chanyu acoustic song feels resentment. China launched to have assumed Mo Yan. Now is not the final wild sent. "shows that the paper had devoted herself to the four already. Yuan "Yuan. Music Zhi "," the sun refused to play the system, the first volume GU Long, Erxian with arch points short, Mawei string to the bow "further expounded the principle of Music production. Music has spread to the south of the Ming and Qing times, and instrumental ensemble accompaniment of folk drama started to become the main instruments. To modern times, will change its name to play the erhu. For more than 50 years, has entered the erhu-time high level. Liu Tianhua is the ancestor of the modernist school, he borrowed the instrument performance practices and techniques are bold, Science will put erhu as five spaces, which took the full expansion of the scope of the erhu, a rich performance, established a new artistic content. Thus, the emergence of erhu from civil Accompaniment out as a unique solo instrument. Entering the Hall element for the future and lay a foundation for music. After the founding of New China, national, folk music developed rapidly, in order to vigorously explore the art from the artist, Hua Yanjun, Liu North-folk artists such as the erhu music is poured into a record after finishing, so erhu and the rapid development of the mushrooming of art. On the 1950s and 1960s, has emerged in the hearts, Shao. Wang B, a representative of a group of educators and erhu soloist, and in their impact, Also cultivate a new performer Feb, Wang Guotong other. Erhu composer Liu Wenjin the "Great Wall Capriccio" extraordinary performance will play erhu and deliberate innovation Huan issued a new vitality and will make the sky. Erhu tectonic structure is relatively simple : the erhu, Qintong, Qin bar, Qin paper, string axis piece, arch bar and extremely heavy. Mao and composed of the arch bridge. Construction of functional components : Erhu erhu ministries from the nine main components and their functions are as follows : A Qintong introduced : erhu is an important part of this push-pull movement through the arch, remove the string after the vibration resonance Qin Paper pronunciation body. Qintong texture and shape have a direct impact on the volume and timbre. Generally used red sandalwood or mahogany wood production. The shape of hexagonal, octagonal-shaped, round after round before 1.80, is commonly used in the Hexagonal. Music Qintong behind a mosaic windows (typically carved var window), not only for decorative Qintong played a role, but sounds Chuan-Tone Music filter there are certain advantages. B. Cam Paper : Mangpi and demoted two snakes, Mangpi better. It is important pronunciation erhu body is the key Zhenyuan, has a direct impact on the sound quality and volume. C Cam rod pillars : the erhu, is the trunk. Not to even go to play the supporting role, but also have a certain impact on overall vibration pronunciation. Some of the material produced TANG Mu Qin bar, ebony or mahogany. More general use of mahogany. Cheap mahogany, with a certain sexual tension. Two levels : D Cam Shaft (also Mingqin Zhen), adjust pitch, on the axis tied with plastic string, tied States under the engine shaft. Cam shaft with two wooden shaft and mechanical axis, both have their advantages and disadvantages. After tuning stability of the wood shaft, * running string to sound easy, but tight song for tuning difficult. Mechanical axis tuning quick and smooth, or Intonation, but not completely through the production of quality, and sometimes there loose, Sliding phenomena easily run string to sound. E bow : Erhu pronunciation is an important tool bar and arch by arch hair is composed of two parts. Bow real purpurea rod is made of fine fibers to moderate. Bow before the bar of performance and flexibility will have a direct impact on results. Bow before useful nylon yarn hair and the hair race, more Mawei, and the best white Mawei, a dark horse tail times. Mawei on the general use of small real purpurea tied one end fitted with wood screws (bow fish), used to adjust the tolerance hair bow. F : is the piece, one instrument sounds, as well as the erhu, one source. Its quality of a direct impact on phonation. At present, there are two issues : One is the metal piece string with tension, timbre, Intonation and sensitivity characteristics. String two silver and aluminum sub-string, the best string of silver; Another is a silk string, the string sound softer than metal magic But who is poor, poor and vulnerable Intonation constantly change. Now it is mostly metal string. G : known share the wife, played on the erhu chord and tangent fixed role. Intonation is also affected to a certain extent. It is made of cotton thread, yarn, plexiglass, plastic and other materials. Its many forms, a fixed extremely heavy, Wound extremely heavy, extremely heavy metals such. Hung is more commonly used around 1,000 pairs of the burden. H : is the bridge between the piece and Jensen Paper body vibration of the media to play an important role in pronunciation. The materials used, it is wood, bamboo, metal and toilet paper, used a wooden Song Festival race, Feng Trojan. Wood Song Festival race soft wood pronounced movements, and honest, Feng Trojan moderate hardness sounds softer and less noise. J : Cam cento end of the child who plays decoration, stability Qin own role. Some are equipped with two adjustable end Huqin child entrusted with nylon deduction adjustment, playing more convenient. The erhu, such as maintenance and repair; Circular Pathway instruments : the erhu; Circular Pathway : Most instruments will be Cam skins, Most of the material produced is made of hard wood and other such instruments and humidity is certainly one of them. Hard wood wood a certain rigid, high-density, fine wood also. Worked in a wet, the air-conditioning and heating admission dry environment, the stress will cause the wood can balance the internal and external circumstances, This will happen when the surface burning wire, and then disappear humidity stability, sandpaper can be used to fight about 502 points. Philip conditional on some polishing. It is adaptable to the hard wood, Bai material is not the kind of situation Wood song it is very easy to achieve a balance between internal and external stress. We propose to use the end of the erhu, the best body should remain in the Qin rosin powder soft cloth wipe, Qin wood glued to the skin and avoid run-on. Erhu in the production of high-grade wood, we use the natural shellac surface grinding, polishing the clearance process. This is a traditional practice has a long history south of the Yangtze River, has a very high demand for workers, the aim is to protect the wood. improve the smoothness of the wood, and strengthen the hand of comfort. So if we can make use of soft cloth rubbing Qin Qin maintain a clean. Qin who has the time to do so in the face of some car wax or wood furniture wax, but it must be shining clean and avoid sticky hands. Second Music is the greatest concern of the maintenance of the skin. Huqin Paper II in the maintenance of appropriate circumstances, it would be a very long life, the premise is frequently used We see most of the music is stored improperly, the damage is not frequently used. Qin Paper will maintain flexibility in the use of capital, which is its vitality, and we do regular exercise, the body is much easier. Timbre is the continued use of the instrument is to pull him out, not Latin America is not no good, the circumstances in peacetime, itself is a maintenance and repair of musical instruments. Proper use and maintenance is correct. Many theoretical knowledge of the book or network maintenance and Qin husk of a number of methods, After all, there is a gap between theory and practice, sometimes the performance gap is not small. I discussed some aspects of the production from the two Erhu Music Paper maintenance knowledge. Erhu to Wanchun example, the first Qin Paper Paper spade is a process that is glued to the skin on the meat will remove debris so, remove skin to uniform perfection, it is crucial that people are tired of the process together. Paper is the second presentation, aimed at drawing Mangpi to its oily, shape stability, then there is scalded skin together key processes, hot skin Objective 1. Qin Qin is stable Paper Paper have not finalized their contraction. 2. It is beautiful, with glossy paper is Cam. 3. Qin protected by the skin of moisture. Paper sets out after the completion of the paper can decide the use of Qin. The third was stealing Paper, the two processes before stealing Paper paved the way for doing so 20.60 uniform tightness appropriate, Qin Qin Tong is difficult to get the skin and under skin of the situation Qin Qin Tong, wood choices Cam Paper. From these processes, as you can see there are two points : 1. To oily. oily skin will have a serious impact on the pronunciation of Qin, she can feel like a brush-point to the paper. 2. Qin's surface has been handled. ZHOU Rong-ting my grandfather would have set Paper 250000 Mangpi second molding processes. These processes will be dealt with the timbre of the erhu and use plays a key role. Qin Paper required for daily use in Offing, Vaseline on, no more skin in the back of Qin Feng Philip. a scaly sitting ordinary, the scales are blown up together with Qin Paper vibration. Without sticky glue can be used, Qin permeability of skin to maintain its natural, it will adapt to the use of the natural environment. So it really erhu where the nimbus. If the outside skin gave shut Qin Qin Paper will be affected by vibration. Qin Qin skin to skin, not in a sound environment for the back again, because skin from the back of Qin Qin Tong face after scraping or grinding, Cam will lead to uneven skin thickness, Qin serious skin would be broken, so I suggest that you should not even try. Should change the colors from the string, Violin, daughter and audio mat proceed (see erhu use and debugging). know their role and can be repeated testing principles to regulate their own satisfaction with the ideal of color. Erhu is not the time to put some decay in the film and the humidity of the region to recapture some desiccant, should also make regular erhu so for recreation.
