The library of the Music Research Institute of the Chinese National Academy of Arts is considered the main reference center for traditional music thanks to the richness and value of its ancient musical scores, manuscripts, instruments, photographs and sound materials. These include 8,000 recording tapes, 1,800 ancient and folk musical instruments, 140,000 books and 22,000 photos.
The most valuable treasures in the library, according to Han Ziyong, head of the academy, are the 7,000 hours of musical recordings collected by several generations of musicians, who traveled around the country for more than half a century.
On April 23, a digital version of the recordings, the Chinese Traditional Music Sound Archives, was launched by the academy and is available to the public for free.
The collection, which includes field work recordings from all over the country made by musicologists of the institute since 1950, is displayed online under 12 categories, including Chinese folk songs, quyi music, Chinese opera music and Chinese dancing music.
Among the most important repositories are six works by Hua Yanjun (1893-1950), also known as Abing, a blind Chinese musician specializing in erhu and pipa. His compositions for pipa and erhu, including erhu piece, The Moon Reflected on the Erquan Spring (Erquan Yingyue), one of Hua's most famous music pieces, were collected and recorded by musicologists Yang Yinliu and Cao An during the 1950s.
Religious music recorded by the musicologists has also been digitalized. For example, in 1953, when musicologists visited Beijing's Zhihua Temple, built in 1444 during the Ming Dynasty (1368-1644), the monks played a type of music, known as jing. This music has been preserved and passed down through consecutive generations of monks over 500 years. They chant while playing different kinds of musical instruments, such as flute, sheng (Chinese reed wind instrument consisting of bamboo pipes) and drums as well as other percussion instruments, such as cymbals of varying sizes.
Since 1987, musicologists from the institute spent several years traveling around Baoding in Hebei province, not far from Beijing. They discovered almost 80 kinds of hand-copied scores similar to jing music, and they recorded nearly 100 hours of recordings played by folk musicians.
"This is the most comprehensive collection of Chinese traditional music, which we want to share with a wider audience. Now, the singers and players who sang and played the music have mostly died, even the musicians who made the recordings are mostly no longer with us. This is why we have a deep sense of responsibility to preserve these audio materials," says Han, adding that since many of the early musical materials in China was mainly kept orally, audio materials are crucial.
According to Han, the launch of the digitalized sound archives also celebrates the 30th anniversary of the establishment of the Memory of the World program, which UNESCO established in 1992 as a global initiative to prevent the loss of important collections held in libraries and archives.
"This heritage is a shared, common legacy that should be transmitted to later generations," according to the website of the UNESCO."Through its international register, which currently lists 245 items from most countries in the world, the Memory of the World enables the intellectual treasures that have been created by all cultures and in all regions to be better known."
In autumn 1993, Henri Lopes, the then UNESCO assistant director general for culture, visited the Chinese National Academy of Arts in Beijing. Qiao Jianzhong, the then head of the academy, invited him to experience the sound archives.
Lopes suggested Qiao to bring them to UNESCO's attention and from 1994 to 1995 the Music Research Institute of the Chinese National Academy of Arts was in contact with the Memory of the World program, and applied for UNESCO assistance in making recordings of 7,000 hours of materials.
"We made very detailed plans before traveling around the country to collect, record, store and classify Chinese music data. For example, when we traveled to Hunan province, we visited 44 counties and cities, collected 207 types of music as well as music books and musical instruments, which are valuable materials for music study and research," recalls Qiao, now 81.
From Oct 30 to Nov 11, 1996, UNESCO sent Dietrich Schuller, the director of Phonogrammarchiv of the Austrian Academy of Sciences to Beijing to investigate the archives of the Music Research Institute.
According to Han, before leaving Beijing, Schuller said: "These invisible treasures have the same cultural importance as those visible ones, such as the Great Wall and the Forbidden City. People will be aware little by little, that we must preserve these sound archives of historical importance as we preserve the Great Wall."
After submitting a nomination for inscription, the sound archives of the Music Research Institute Chinese National Academy of Arts-7,000 hours of recordings-have been included in the UNESCO Memory of the World program in 1997, the first time for China.
"During the past two decades, we keep our tradition of collecting and preserving Chinese music with many young musicologists traveling around the country to do recordings for folk musicians. Our catalog for sound is growing bigger and bigger. We will keep on adding new materials to the digital library," says Han. "Hopefully, the digital library won't just appeal to musicologists and scholars. We want more people, especially young people, to get to know those music materials, which, beyond music itself, tell about history and culture."
So far, besides the sound archives of Chinese traditional music, 13 items from China have been included in the UNESCO Memory of the World program, including ancient Naxi Dongba literature manuscripts-approximately 20,000 volumes.
