<WBR>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? <br>

<div>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.</div>
<div> </div>
<div>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. </div>
<div> </div>
<div>Ideas? Can not enough downbearing cause tuning instability? </div>
