When we gradate the boundaries between two polarized things, the two become smoothly connected. By blurring the various boundaries, we can find complexity, diversity, and richness of information.

Lyrics:
Gradation Gradation
Gradation Gradation
White and black
Smoothly
0 and 1
Slightly
round and square
Gradually
The border between them melts
blend together
Gradation Gradation
Gradation Gradation
blurring the difference between the two
Make the transition more subtle
Smooth out the differences
The middle
increase
Connect
Gradation Gradation
Gradation Gradation
