Could it be that this represents a system for generating music?

[ololololo]

it concerns the techniques of musical composition.

What is the essence of this methodology (creating a musical composition or something like that)? What makes it special? Can it be compared to the medieval conception of music?

Why was it necessary to hide and encrypt the music in this way? What is the point of making a music book as inconvenient as possible by styling it to look like a herbal?

I won’t stop trying to understand your point of view.
