Hello Tom and List
I suppose it's not at all helpful to state the obvious - "it's in =
Archives"! No? Well then this is the way to do it:
Have a cheapo ETD - you know the things - get it from a guitar shop. =
They usually have A=3D439 to A=3D445 or so. With that tune all the A's =
to the A=3D445 - all 8 of them. Next tune the intermediate M3's i.e. all =
the C# and the F's. Now quarter of the piano is done.=20
Next recalibrate the ETD to A=3D444. Now tune all the G's to 444 pitch =
and follow that with their intermediate M3's - i.e. all the D#'s and all =
the B's. Now you're half-way!
Next recalibrate the ETD to A=3D443. Tune all the G#'s and then the =
intermediate M3's. (three-quarters of the way!)
Last recalibrate the ETD to A=3D442. Tune all the F#'s and then the =
intermediate M3's
And you're done!
Now fine tune.
Note this... I ALWAYS DETUNE EACH STRING SLIGHTLY BEFORE PUTTING UP THE =
TENSION. This breaks the bonding at the pressure bar or capo. Even use a =
touch of de-oxidising fluid at those points before you start.

    Hello List
    . <SNIP>So I used my "Quadrant System" to bring it up to A=3D440 and =
fine tune it in two hours. <SNIP>
