Here's george secor's favorite harmonic entropy curve:

you can label the local minima easily if you understand the stern-brocot
tree.

Is that all you're saying? If not, can you draw something on this diagram to
demonstrate what it is you are saying?

I'm not aware of any formal relation between the tenney harmonic
distance and the tree.  Also, it means to ask about "triadic" trees,
which have been mentioned in passing on the list(s) but never "found".
