Guqin notation

note, or sometimes as many as nine. This notation form was called jianzi pu 〔減字譜〕 (literally "reduced notation") and it was a great advancement for recording qin pieces. It was so successful that from the Ming dynasty onwards, a great many qinpu 〔琴譜〕 (qin tablature collections) appeared, the most famous and useful being "Shenqi Mipu" (神奇秘譜, lit. The Mysterious and Marvellous Tablature) compiled by Zhu Quan, the 17th son of the founder of the Ming dynasty ^[1]. In the 1960s, Zha Fuxi discovered more than 130 qinpu that contain well over 3360 pieces of written music. Sadly, many qinpu compiled before the Ming dynasty are now lost, and many pieces have remained unplayed for hundreds of years. ^[2]

Qing, this was replaced by the decimal system. The space between two hui were split into 10 'fen' 〔分〕, so the tablature can indicate the correct position of notes more accurately, so for the examples above, the correct positions are 7.6, 6.2 and 10.8 respectively. Some even went further to split one fen into a further 10 'li' 〔釐/厘〕, but since the distance is too minute to affect the pitch to a large degree, it was considered impractical to use. Some people argue that the old system is just as accurate as the new system when qin tuning theory is observed.^[3] Also, these old positions may actually conform to the rules of equally tempered music, with its pitches slightly flatter, such as in the case of 8 for 7.9 and 11 for 10.8. Another main property for this old system is that it requires the player to "feel for the note", just as one would do for any other fretless stringed instrument, be it erhu or violin

staff notation combined with some tablature marks ^[4]. Others have tried to write a computer program that will do this. Chen Changlin, a Beijing-based computer scientist and qin player of the Min (Fujian) School, developed the first computer program to encode qin notation from ancient tablature sources. ^[5]
