Trichords tuning

[Newton Hunt]

"Interesting that your piano showed a *rise* in pitch. The ones I have
checked (small pso's) showed a drop in pitch with all three strings
sounding."

I think this is because you can tune on string, say to an SAT, tune the
next by ear, check with SAT and it is flat.  Tune to the SAT and compare
unison and it is out.  I have yet to come to an understanding of this, I
just know it is so.  Weird!

 If you tune the string that wants to be the lowest then the others that
want to be sharp you should have a unison that is sharp instead of flat.
