Pitch Raise, was: Standard Pitch

[cswearingen@daigger.com]

Hi Kevin,

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

Corte, let me ask you this; do you ever find yourself doing the second
pass, and you do a test blow that ends up being five or six cents flat?

The time for test blows is indeed after the pitch raise (and during it, but
definately after it also) . The speaking length may indeed be at pitch, but
if you don't have all segments of the string up to tension, it's going to
go south.

After doing a pitch raise, I don't really feel like yanking the strings up
all over again.

Just something for you to think about while you're out there tuning, that's
all.

Kevin.

 Like Terry, I'm a bit confused on this as well.  To me, the purpose of a
 pitch raise is not to necessarily leave a note sharp, it's to leave a note
 a close to the target pitch as you can.  Some notes will be slightly sharp
 of target and some will be slightly flat of target.  If I do a pitch
 raise,
 there is no need to do a subsequent rough tuning - just a fine tuning.
