The development of notation

The development of notation is character spectrum, sound zigzag, subtraction spectrum and I scale spectrum.

Notation refers to the method of recording music with symbols, words, numbers or charts. The images it records are called music scores. This symbol is very different in different countries and at different times. The development of notation is from the figure spectrum in Wei, Jin, Southern and Northern Dynasties to the sound twists and turns in Han Dynasty, the subtraction spectrum and music accompaniment spectrum in Tang Dynasty, the palace pool spectrum in Ming and Qing Dynasties, and now to the tube chromatography, folk figure spectrum, temperament spectrum, lattice spectrum, elegant music score, curve spectrum and so on.

In the notation of modern Chinese characters in China, 1, 2, 3, 4, 5, 6 and 7 are mainly represented by Gong, Shang, Jiao, He, Zheng, Yu and Bian respectively, while in the notation of scales, they are represented by Shang, Chi, Gong, Fan, Liu, Wu and B, and diagonal lines are drawn under and beside Chinese characters.

Western traditional music

The traditional notation system of western music is based on the standard that each octave contains seven basic levels. However, when five variable levels are added to the keyboard at the end of 17, the system has serious problems. In the traditional notation, 12 sounds are not recorded equally on the spectrum, and there is no line or interval that changes the sound level. Therefore, at least one extra piece of information needs to be explained, which will affect the short-term memory of the reader.

This inequality leads to two greater difficulties. First of all, some key signature sounds simple, and some key signature sounds complicated. In fact, their interval structure is exactly the same, but the absolute pitch is different. Secondly, the pitch distance seems unclear, that is, the vertical proportion of notes on the spectrum is uneven. The pitch distance between two notes is not directly expressed from the position, but depends on the reader's understanding and memory of the harmonic clef he plays.
