chord mathematics is a mathematical model of chord language. The main features are: octave duodecimal number system, symmetric, mirror phase, and spatial expression of chord language, also known as "chord geometry".
Chord mathematics is scattered in various disciplines related to chord language, such as musicology, chord colorology, meridian science (life expression), etc. In this paper, quantitative, number system, positive and negative, coordinate, formula, calculation method and so on are integrated and unified.
Chord language is composed of chord spectrum, with quantum, string (opening, closed string, N string), symmetry, mirroring and other physical, mathematical (geometric) characteristics, manifested in music (time expression), painting (space expression), meridian (life expression) and other disciplines, with spiritual, physical duality, it has thousands of years of accumulation of understanding, The more mature mathematical model, which can be observed and verified, should be the characteristic of the theory of everything.
