Chords Extension



What if it extends to chords with more than three?



All sequences of 3 chords




When it adds an extra corner, it adds more possibilities. 



some sequences of 4 chords




Here, it takes examples to study further.



standard 3 chords



rectangle in 4 chords




Take the equilateral triangle and rectangle as an example for comparative study, also, with different areas, from small to large.

quadrilateral from small to large





We use a gradient as a color flow for the notes visualization. Because, from the chapter Basic Concept of Sound, a note is an abstract symbol for a pitch, and a pitch depends on the fundamental. Ideally, it should be a single fundamental we hear; however, in reality, except for the fundamental, there are certain partials overlapping, and the fundamental and partials, with their own different amplitudes, overlap together at the same time — that’s a tone we hear.

Therefore, the gradient should be vertical when it is played at the same time, whereas horizontal when it is played through time.

From the color flow, we can see that the smaller the area is, the closer the color flow is.
