Provides for the pitch d, f, a, c, and f-line painted red, c painted yellow line (later to become Zhonggao Yin Staff and the origin of the bass clef). The 13th century was the first use of 5 lines, to become the predecessor of Staff. 16th century and increase the line to make the pitch more complete records.
规定音高为d、f、a、c,并将f线画成红色,c线画成黄色(后成为五线谱中高音及低音谱号的起源)。13世纪有人使用第5根线,成为五线谱的前身。16世纪又有加线的办法,使音高的记载更完备。
