Young Chang tuning instability

[Willem Blees]

I agree with Bob. Ask the customer if he's doing some "tuning" between visits. How often do you tune the piano? If he's a banger,?you might want to recommend once a month, instead of twice a year. You might also want to take a look at other sources of tuning instability. Look for heat/AC vents, and?doors?and windows.?Is the piano close to the kitchen,?and where is?the washer and drier? ?

Subject: Young Chang tuning instability



I have regularly tuned a Young Chang PF-250 for about a year, and it sounds horrible every time I come back for another tune.? In the tenor section, one note might be?+15 cents, while the one?next to it is -15.? ?Unisons are completely unacceptable.? Bass section and high treble seem to be okay.

?

The person who plays this piano is a "Horowitz", plays very hard, but I still think the stability could be better.? Plate bolts are tight, tuning pins have sufficient torque, I have seated strings, and I pound the heck out of it every time I tune.? 

?

Ideas?? Can not enough downbearing cause tuning instability??
