I wish to contribute another "spanner in the semantic works"

Has anyone else found the amazing term <"enharmonic overtones">
referred
to in the hardcopy world libraries of tuning?
I found it a number of times in libraries in London, and was amused
at
the time, yet I am currently having difficulty in quoting book, page,

para, etc.
Back to the lab to complete u/water speakers for the big blue Pacific
cetacea.

What Gary describes with the tied-around wire may be happening constantly
on a smaller scale in real wire, nylon, and (especially) gut strings. The
presence of imperfections at nodal points cannot but affect the timbre.

Oh, that only applies to the odd (former) harmonics.

That experiment has lead me to want to figure out a way to fabricate
more gradual nonuniformities, especially a conical string, which (at the
proverbial quick glance at least) I would think to be more or less
acoustically analogous with a conical wind-instrument bore.

Dan is certainly correct here. I think - again based upon my reasearch
- that a better phraseology would be "on a vastly, FAAAAAR smaller scale".
But he's certainly correct that the effects of those imperfections aren't
COMPLETELY negligible.

And his point that they're much more prevalent in gut strings is
certainly astute and accurate.
