One cannot discuss Chinese music without mentioning the Chinese seven﹣string zither （七弦琴） ， also known as the guqin， one of the four arts ﹣ along with go， calligraphy and painting． It first appeared over 3， 000 ago and represents China's solo musical instrument tradition．

    At first， the guqin had only five strings， representing the five elements of metal， wood， water， fire and earth． Later． in the Zhou dynasty， King Wen of Zhou added a sixth string for his son， King Wu of Zhou， added a seventh string to encourage his army to fight with the Shang．

    Ambience （环境气氛） was important in playing the Chinese zither． Usually， it was practised in quiet setting and never for public performance．

    Ancient artists enjoyed performing by a stream in the mountains． The sound of the guqin mixed with the echoes （回音） from the mountains， until the musician found himself at one with nature． Playing it in snow was also a favorite pastime for ancient artists， who believed the instrument was the purest of its kind in the world． Also． a night with moonlight was considered ideal for Playing the guqin． Wang Wei （701﹣761）， a highly talented man of the Tang dynasty， liked playing it in a bamboo forest on nights with moonlight most．

    Guqin pieces are usually around three to eight minutes long， with the longest being Guangling Verse， which is 22 minutes long． Other famous pieces include Plum Blossoms in Three Movements， Wild Geese Landing on the Sandbank and Eighteen Songs of a Nomad Flute．

    Nowadays， there are fewer than one thousand well﹣trained gugin players and perhaps no more than fifty living masters． The original number of several thousand pieces has greatly reduced to only a hundred works by today． The guqin and its music was added to the list of the Intangible Cultural Heritage of Humanity （人类非物质文化遗产） in 2003．
