"If the piano is more than 8 cents off pitch it should be tuned a second =
time that day
to even off the tension. Just think how well the piano will sound a few =
years later..."

I'm trying to understand what you are saying here Jon. Are you saying =
that if the piano is more than 8 cents flat (or sharp) you should first =
do a pitch raise, and then do a separate tuning immediately after (or =
later in the day for some reason?)? Please differentiate between tuning =
and pitch raise and how many passes you might commonly do. If a piano is =
5 cents flat do you commonly only do one pass, raising the pitch 5 cents =
while tuning? Thanks.

    Any thoughts?

  If the piano is more than 8 cents off pitch it should be tuned a =
second time that day
