[pianotech] "Stealth Temperaments" or sumpin' like that<G>

[David Nereson]

     Most people can barely hear a one-cent difference in pitch, never mind
a tenth of a cent.  And you're going to try to tune to the nearest
hundredth of a cent?  What's the point?  It's like trying to mow your lawn
to the nearest 64th of an inch.  There's too much nitpicking over the
inconsequential in this business.
     Some of these "historical" or non-equal temperaments seem to achieve
about the same result as letting the piano go out of tune for a few months,
or even a year or two, then tuning just the unisons without setting the
temperament.  I've tried several of them and I still maintain that the
difference is so subtle, it's barely worth bothering with.
