<DIV><FONT size=2>I'd probably agree with most of what JF has said below. It is
a feel thing based on roughly a 1/3 over pull on my first note A440. >From there
I usually tune single strings everywhere but the bass. A couple extra beats
going into the tenor break, then backing off into the treble. I save the bass
for last, after pulling up the unison elsewhere, I simply don't want to break
bass strings. Every piano is different and you get to know how they will behave.
Old rusty Chickerings are not going to be yanked up 1/3 over when they are 100 c
flat. Common sense there. Suesan Graham wrote 15 or 20 years ago that the
further flat the piano is the faster she tunes, as things get closer, slow down
and be more careful. Sometimes I am absolutely right on after a 20 minute pass
from 100 cents flat, other times the treble is still down. If things aren't
behaving properly one should be looking at things like pin block fit or bridge
problems. I like to spend a bit of time on the temperment even on pitch raises
because I want to start creating that foundation right away. I enjoy the
challenge of pitch raises. It's kind of like archery.</FONT></DIV>

<DIV><BR></DIV>John,<BR><BR>I'm assuming you mean a pitch "raise."<BR><BR>I
haven't done any personal studies on it, but I accept the fact that one will
get a more accurate and stable pitch raise by tuning unisons as he goes, from
the bottom up. I think Dr. Sanderson proved this many years ago, and my
time with the Verituner confirmed this to me. <BR><BR>As a strictly aural
tuner now, though, I don't have a choice except to tune from the middle
outward, unless it's a "blind" pitch raise, which I personally never got the
hang of. The way you get the right overpull is to do pitch raises enough that
you know sort of what to expect. It becomes less of a guessing game and more
of a "feel" thing. You could think of it as knowing how many beats sharp to
tune it. As you learn through experience, you will find certain types of
pianos behaving more predictably. I generally set A4 1/3 more than it is flat;
e.g., if it's -10¢, I'll set it to +3¢.<BR><BR>I use strip mutes in the whole
piano, "Dan Levitan style." It takes about 15 minutes for a pitch raise. It is
generally not as accurate as an ETD, but I have had occasions that many
strings were as close as an ETD could get in a first-pass pitch raise.
<BR><BR>There is probably lots of stuff in the archives. Good luck searching
for it!<BR><BR>JF<BR><BR>
