Yes, and okra. Oddly enough though, while I've gotten many requests to play
a little something after a tuning, no one has mentioned "Lady of Spain" so
far. But it's early yet, so I suppose there's still time.

Yep - temperament foundry - roll your own and collect them all. It's easy,
and anyone can play.

Yea, we futurists laugh at sound checks, stage lights, and the concert on
the veranda when the sun comes out. The piano knows what to do, we just
stands ourselves back and tries to stay out of the way. It don't hurt none
to carry an extra fuse or two though, just in case.

Ah yes, an allusion to a guitar fetish I played with for a while at one
point. Nothing serious - just an attempt to "Muddy" the "Waters" a tad.
Found I was more suited in talent and temperament to hunkering over a
snooker table, but it's all a matter of how you slice it in the end. That
too has since passed, as well as the guitar efforts. Pity, I thoroughly
enjoyed both.

My first thought (OK, maybe my second) was that this electrofucatin can
only LOWER the pitch. There's nothing in the system that can raise it
except the service guy who comes around every five or ten years to sweep
the chunks off of the soundboard and pull the piano above pitch. You've got
to have someone of both extraordinary fortitude, and an unusual capacity to
generate enormous clouds of apparent legitimacy to take on this sort of
thing. I think (I think) maybe the brain tumors come with the job,
regardless of the medium. We's all susceptible, nevermindedness of our
association with self tuning, self tunable, or tuning challenged pianos.
Still, it might just work better that we would normally expect.

Hey, most anything can be improved (at least perceptually), by being tuned
daily. Seems to me that I regularly read something to the affect that
pianos of questionable pedigree and indefensible design philosophy are
being made less bad to the point of being acceptable under narrowly defined
specific circumstances by the repeated application of service at a rate far
beyond that indicated by the condition and potential of the piano. Maybe
it's just a matter of perspective.

Well, good sense has been around in limited quantity for a good long while
too, but doesn't seem to have been all that enthusiastically embraced by
the general populace to date, so there's a finite chance that we just might
not be looking at the right thing here. Or not.

Looking for a few good notes....
