<DIV><FONT size=2>Interesting. I had to tune two D's (one 1917, one
current C&A) and a C3 together for a three-piano concert. TuneLab
saved the day for me. I measured iH on all three pianos (A's from A1 to
A6), then went home and tried various bass/treble octave styles to see where A0
and C8 wound up. After finding a few close matches, I then looked closer,
to get the best fit for A2, A6, and A8.</FONT></DIV>

<DIV><FONT size=2>The best fit overall was 3:1 twelfths in bass and
treble. I still have the data somewhere if anyone's
interested.</FONT></DIV>
