Zhang Kun, a senior experimenter of Shenyang Conservatory of Music, an expert in piano tuning and maintenance, and a reformer of national musical instruments, cooperated with experts in the music industry and musical instrument industry to adopt a three-dimensional double-sided pipa-shaped resonance box and a zither-shaped goose column, and borrowed the form and string array of the harp. Design, absorbing Han Qihua's "double-row string vibration" structural principle, successfully designed and produced Yanzhu Konghou, making the thousand-year-old music on the world music scene with a new look.

In the spring of 1978, at the concert presented by the Central Chinese Orchestra to the National Science Conference, the "Double-stringed chords and trembling Konghou" developed by Han Qihua first appeared on the music stage in the capital. ", which aroused great shock and interest in Zhang Kun. This kind of double-row string konghou has a lever on the upper end of the string, and the tension of the two strings is balanced, so that it emits the same sound. Under the action of the lever, it can play kneading, sliding, pressing, vibrato, etc. Sound effects, this is undoubtedly the direction and breakthrough of Konghou's reform, and it is also where it has strong vitality. However, because the resonance box of the harp is used, the tension of the strings is large, and the double-row strings, the pronunciation is limited, so the volume is relatively small. And because of the limitations of the structure and layout, the transfer has become a problem. In order to develop the art of musical instruments as soon as possible, Zhang Kun was thinking, thinking...

Zhang Kun is a senior experimenter at the Shenyang Conservatory of Music. He has been engaged in piano tuning and maintenance for a long time at the Conservatory of Music. He is already a well-known piano expert. He also actively participates in the reform of Chinese national musical instruments. As early as 1958, he designed a keyboard sheng according to the pronunciation principle of sheng, with a sound range of four and a half octaves and a better harmony effect. "middle. After 1958, he cooperated with Cui Zuoxin to study the problem of guzheng transfer. After four generations of thirteen drafts and 20 years of continuous improvement, he finally successfully developed the column-shifting zither in 1978. In 1981, he was awarded the Liaoning Provincial Major. The third prize of scientific and technological achievements, the fourth prize of scientific and technological achievements of the Ministry of Culture.

In 1979, my country organized experts to attack Konghou.

In March 1980, my country's first Yanzhu Konghou was successfully developed in Suzhou (pictured). It has 72 double rows of strings, 36 strings in each row, and the corresponding two strings are in the same tone. The scales are arranged according to the C major heptatonic scale, ranging from A1 to a3, up to five octaves. The timbre is bright, similar to the guzheng, and the overtone effect is like the guqin, which is very expressive. It can play arpeggios, chords and polyphonic melodies, especially kneading, sliding, pressing, and vibrato. with ethnic style. Reach the level of professional performance use, can be used for solo, duet or accompaniment to song and dance and other instruments, and can play in concert with national or Western orchestras. At the opening ceremony of the National Ethnic Minority Art Festival held in September of the same year, Cui Junzhi, a Konghou soloist of the Central Chinese Orchestra, used this Konghou to solo the ancient song "Three Lanes of Plum Blossoms" and played "The Fishing Boat Sings Evening" with Gaohu duet. The tremolo method simulates the sound of the guzheng, depicting the magnificent rivers and mountains of the motherland and the joyful scene of ancient fishermen returning home with a fruitful harvest. The image of Cui Junzhi playing this Konghou at that time was included in the large-scale picture book "Chinese Musical Instruments Illustrated Guide".

In 1997, a popular Yanzhu Konghou with concise structure and low cost was successfully developed by the author and Zhang Kun of Shenyang Conservatory of Music in Beijing.

This popular Konghou adopts vertical double-sided trapezoidal resonance box, the soundboard is made of sycamore wood, the surface is arched, and the thickness distribution is scientific and reasonable. Zhang double rows of strings, 36 strings in each row, a total of 72 strings, and the corresponding two strings are of the same tone. The sound column is arranged according to the C major heptatonic scale, with a range of C-c4, a total of five octaves. In the string row, d-c3 can play kneading, sliding, pressing, and vibrato effects through the lever device. Like the Yanzhu Konghou, it can use the playing techniques of guqin, guzheng, pipa and harp. The sound quality is bright and beautiful, with rich national characteristics.
