Then = what would you do if the piano is 50 cents flat of your target " You have to "play all this by ear" as it were. The object of this system = is to spread the load equally over the whole piano at all times - rather = than tensioning it up chromatically. So view your specimen piano with a = jaundiced eye and tell it "I'm going to get you to pitch" ;-) The ETD I use for this exercise is a cheapo one with a meter calibrated = + or - 50cents. This will tell you how much the piano is flat. Then I = set the meter to Zero on A=3D446, or 445, or whatever, and go on from = there. For each 10 cents the piano is flat I raise the first quadrant 1 = Hz. So if the piano is 60 cents flat I start my 8ves. at 446Hz. then = fill in with the quadrants (by ear and 8ves) then go down a whole tone = to the next quadrant and do that in the same way but this time to, say, = 445. Next I go up a tone-and-a-half and that would be 443 Then finally = down a tone to the last quadrant and tension it up to 441. Do you see = what I'm doing here? Start on the B quadrant, then the A quadrant then = the A# quadrant and finally the G# quadrant. Point is, obviously you = tension up the whole note - all three, or two, or single strings, = otherwise the system becomes incredibly cumbersome. You only need one = wedge for all of this. And you use the ETD on all 8ves throughout the = range of the piano. This gives you that all-important "outside = reference" not being affected by the changes in tension within the = piano. What more can I say? I developed the system. It works (at least = it does for me) and it'll work for you too.
