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

I have read your article @Maruyama Toru, it seems to me it does not concern just music: you propose the 'grafting' interpretation for features of some plants root, a musical interpretation for Bio/Balneo, Zodiac etc., and what you call 'Hanasaki system' for some other diagrams. This cab be not immediately clear to someone reading this thread.

I told you to be careful, because it's easy to see in Voynich imagery whatever one wants to see. It's not that you are wrong: you might even be right, we just don't know, but your ideas ('hypothesis') are just one set in an innumerable list of possibilities. Putting forward an idea is not enough, you also need convincing evidence.

(talking about plants) this may evoke the relationships among the elements that constitute a musical figure, as well as the process by which a musical figure changes and develops while taking shape as a motif

Yes, this might be, nothing which is not logically forbidden is impossible, but it also might be not. I remember someone proposed plants represent noble lineages of people (or something like that). Here too: it might be, but it might be not, ie.: plants could represent musical figures... or anything else, really. Can you show how to construct a counterpoint (as you suggest in the article) musical figure starting from an Herbal page? That would be something. It's a hard world.
