参考译文
The very instant that the classical music gets hold of you．one call clearly visualize the mountain ranges，the running streams，the elegant bamboos，the winter snow and the eternal life flowing in the air．That kind of emotion，unable to be clearly articulated．epitomizes the serenity of Chinese classical music．Traditional musical instruments usury serve a dual role-both entertainment and pragmatic use．Not only are they the instruments to play music，but also they are often tools of laboring or daily utensils．Chinese music is an integral part of China's rich and profound culture．Having developed for thousands of years，it becomes famous all around the world due to its rich varieties and systems of abundant connotations.
难点注释
1．第一句中，“……的一刹那”指“一瞬间”，翻译为the very instant比较贴切。
2．第二句中，“那份说不出、道不尽的感动”主语是“感动”，属于一种情感，因此翻译为  emotion：“说不出”与“道不尽”是一个意思，因此整合翻译为unable to be clearly  articulated。
3．第三句中，“双重功能”翻译为dual role，role具有“作用”的意思，比function更贴切。
4．第四句中，“光辉灿烂的”翻译为rich and profound。
5．第五句中，“以其多姿多彩的品种和内涵丰富的体系”是其“闻名于世”的原因，所以应翻泽为due to引导的原因状语。
