Chord language is the natural (physical, mathematical) coding language of time-space and life. In chord language, music, painting, life, physics and other disciplines depend on each other. It can be expressed by chord mathematics. It should be the theoretical feature of all things.
Chord language produces semantic expressions of time, space, life, spirit, etc. in the disciplines of music, painting, meridian (Oriental ancient medicine theory) and so on. The basic forms are: quantum discrete spectrum, chord geometric semantics (open, closed, membrane string), with physical, mathematical forms: quantum, string theory exists in music, painting?
Music and painting are the most common chord language phenomena. In chord mathematics, the two are reverse-mirror relations, respectively expressing: time and space. Can directly present the nature and relationship of time-space.
Chord language is not only a spiritual phenomenon (music, painting), but also a physical phenomenon (discrete spectrum, string), observing chord language events, such as: music, painting, etc. - also observing physical events, it has spiritual-natural isomorphism, This is its philosophical significance.
The chord language is an ancient knowledge system, and its mathematical model can be traced back to the Pythagorean law of ancient Greece, gradually perfected by musicians of all ages. The chord geometry can be observed in chord painting: open string, closed string, Membrane string, which is predicted by string theory. Meridian (Oriental Ancient Medicine) observes the positive-negative (yin-yang) coding rules of chord language: they form the basis for observation and verification of chord language.
