Pitch Raise, was: Standard Pitch

Terry,

When you Pitch raise a piano , the bridge tend to roll, and you lack front
bearing.

I  have good tonal results having the pitch frankly sharp, (445 or such)
then coming from above after a few days.
In that case, the lowering tend to allow the bridge to go back in a better
configuration.

Second, the back scale may take some time to even, some pianos if bring at
440 - from 438 for instance, will well return to 439 on some notes after a
few days.

If we plan to bring the piano to pitch it may be done from above, you can
then bang it there and believe it will stay put.

But another thought is I don't do that the same in automn or in spring, most
pianos have a variable strech tuning during the year, it may be useful to
tune in regard of the season, if we have an idea of how it will turn
afterthat.

Automn : tight tuning (will open in Winter), in March, more open, mostly
around the break, to avoid the exagered pitch raise around the break that
occur in humid season I also leave the pitch drift at the end of the
school's year.

As on an enough tuned piano the tuning pins and strings "know" where to go,
I don't have to think about it too much in fact -it is a case where the use
of the EDT may bother you because forcing you in a tuning that is not
exactly corresponding with the seasonal state of the piano. Most aural tuner
do that instinctively, feeling the piano getting in its place (we are
talking 2/years tuning at last there)

Best Regards.

    Hi, let me say it again, as sometimes I think I'm writing posts to
myself on pianotech.

    No, I read it, but I don't understand it.

    A pitch raise, my definition:

    The purpose of a pitch raise is have all strings slightly or more sharp
than "standard pitch"

    The object of my pitch raises are to have all strings at target pitch.

    A pitch raised piano is an out of tune piano, but sharp to " standard
pitch"

    Why would you want the piano sharp? If the client wants their piano at
A440, I would recommend that one tune it to A440, not something sharper.

    unisons are not in tune, 4ths, 5ths octaves are close or wildly out of
tune

    and that only takes about 15 - 20 mins!



    Then, you do your first rough tune to get it sounding close. It is
because it is easier to tune from sharp to correct pitch than to pull up
from flat


    shall I go on?

    Sure. But it seems to me easiest to tune a piano that is already at
target pitch than one that is either sharp or flat.

    Brian

      Hello Terry Farrell
      I don't think there can be such a beast as a 15 minute pitch raiser.
This is an idle boast. I'm with you in setting this up as a test! I use my
patent "quadrant" approach (see post "Raising Don Rose to Standard Pitch" )
I hope Don will forgive my blatant use of his name to identify a partic.
posting!!!
