<HTML><FONT FACE=arial,helvetica><FONT SIZE=2>Hello Corte,
<BR>
<BR>If I'm pitch-raising or tuning a new piano(I seem to be doing alot of th=
ese lately), I will generally play the upper treble notes really hard at lea=
st once up and down the scale from the treble break before I ever set =
hammer to pin. Dogs will usually make their way into the other room du=
ring this procedure.
<BR>
<BR>This gives me a better idea of where the tension was/is, as most of the =
time on mass-produced pianos, the notes will sink dramatically in pitch. &nb=
sp;It will then be easier to calculate how much you'll have to pull it up wh=
en you start turning pins, and the piano will be more stable in the long run=
. It can take forever if you keep bringing it up, then beating it down=
.

<BR>Hi Kevin,
<BR>
<BR>The only problems I sometimes have after my initial pitch raise is that,
<BR>during the fine tuning, the extreme treble (depending on the piano) can =
be
<BR>knocked down 5-6 cents with hard blows. To keep this from being a =
problem,
<BR>I simply bring the pitch back up while repeatedly hitting the key to
<BR>stabilize the note. This seems to work quite well for me. Ma=
ybe I should
<BR>also note that I use an impact hammer for both pitch raising and fine
<BR>tuning.

<BR>Corte, let me ask you this; do you ever find yourself doing the second
<BR>pass, and you do a test blow that ends up being five or six cents flat?
<BR>
<BR>The time for test blows is indeed after the pitch raise (and during it, =
but
<BR>definately after it also) . The speaking length may indeed be at pitch, =
but
<BR>if you don't have all segments of the string up to tension, it's going t=
o
<BR>go south.
<BR>
<BR>After doing a pitch raise, I don't really feel like yanking the strings =
up
<BR>all over again.
<BR>
<BR>Just something for you to think about while you're out there tuning, tha=
t's
<BR>all.</BLOCKQUOTE>
