In the notation of guqin, the subtraction notation founded by the pianist Cao Rou at the end of the Tang Dynasty is a major reform of the notation of words, which is characterized by "concise and elegant words".
Born in 730 AD, Cao Rou was a pianist in the prosperous Tang Dynasty. Created the subtraction notation, which was later modified by Qin people in previous dynasties and is still in use today. Cao Rou's greatest contribution to Qin culture is that he created the notation of Guqin Chinese characters on the basis of previous notation. Although the spectral subtraction was basically perfect in the Ming Dynasty, it did not leave the basis of Cao Rou's spectral subtraction.
Subtraction spectrum is generally divided into four parts, the upper part records the left-handed fingering, the lower part records the right-handed fingering, the upper left is the left-handed fingering, the upper right is the embossed emblem, the lower part is the right-handed fingering, and the inner part is the plucked string.
