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

And then, I find myself asking: what exactly *is* a "root"? The answer is that it isn’t actually a plant root. So, what is it, then? Well, it’s something that looks exactly like a plant root.

In other words, what has been depicted here is something that bears a striking resemblance to a root.

So, if it looks like a root and walks like a root... is it a duck?

That’s just how it looks, isn’t it? Instead of focusing on appearances, why not consider the fundamental nature of roots?

The function of a root is to take in water and nutrients, and to transport them from the stem to the leaves. In other words, it is the primary organ that sustains life—or, metaphorically, the initial starting point of any endeavor.

What we see here is a model—a representation—of that concept, cast in the form of a root.

So, what exactly is being modeled? Uncovering that is the key to solving the mystery.

Hint: A specific technique is used to connect the roots and the stem. Let’s take a close look at the illustration.
