Ancient music notation

In ancient China (BC 1000 years), the music of court sacrificial banquets (elegant music) was recorded by Lu and Gong Shang. The former uses the names of China's Twelve Methods (that is, twelve semitones within an octave) (Huang Zhong, Lu Da, Taiqun, Jia Zhong, Gu Xi, Zhong Lu, Yan Bin, Lin Zhong, Nanlu, Yize, Wushe and Ying Zhong) to record music. The latter recorded music with five ancient phonetic names (Gong, Shang, Jiao, Zheng and Yu) and became popular in the Western Zhou Dynasty. The Book of Rites written by China in the Han Dynasty? The chapter "Touhu" retains the drum music played in ancient times. The music scores of the two drums in the pot toss game are described by three musical symbols: mouth, χ and half. This is the earliest spectral record. Hanshu? There is a record of the coordination between "sound twists and turns" and songs and poems in the Records of Arts and Literature. It is inferred that these "sound twists" should be music scores when singing songs or poems. In our country, people are used to recording music with a variety of character spectra. Such as subtraction spectrum, half-moon and half-word spectrum, gongs and drums, twenty-four-character spectrum and so on. During the Southern and Northern Dynasties, the piano music "Jieshi Tiao Youlan" handed down by Qiu Ming in the Southern Dynasty (493-590 AD) recorded the piano playing techniques in words, indicating that the music score is still the common music score of Sui, Tang and Qin people. The development from Chinese character notation to subtraction notation is an extremely important innovation of Guqin notation. This change was completed by Cao Rou in the Tang Dynasty. The specific method is to spell out some symbols with the strokes of subtractive strokes as the marks of left and right hand playing techniques on the phonemes of guqin. This is a notation that only remembers phonemes and playing methods, but not names. For example, the big nine above refers to the big finger and the nine emblem (there are thirteen points outside the piano called the emblem, which marks the position of the overtone phoneme), the big nine refers to the simplification of the middle finger playing technique, and the six refers to the sixth string. This "word" has always been the meaning of pressing the nine emblem with the left big finger and hooking the six strings with the right middle finger. Because fingering is marked, it is also called "Finger Score", which was gradually finalized in the Southern Song Dynasty and is still in use today. Its appearance enabled a large number of piano scores before Sui and Tang Dynasties to be sorted out and passed down to later generations. Banquet and music half-character spectrum is one of the traditional folk spectrum in China.
