Abstract: It has gradually become one of the important issues that the playing techniques, timbre of various musical instruments and the mindset, and physical movements of their players are documented accurately and effectively. These issues need to be urgently addressed by composers and musicians. In the process of continuous exploration by composers, the combination of graphics, words, and the traditional Western staff notation has become a primary means of recording the playing of traditional Chinese instruments. Curves, straight lines, and dotted lines, whether as independent symbols or as materials constituting graphics, play a vital role not only in ancient Chinese notation systems but also in the Western notation systems, and in other ones.
