This is the way I have found to be most effective as well. I would characterize my method for fine adjustment as a "mini-slap" ...a small jerk not only breaks the string loose but it also breaks the pin loose. If you make small movements without moving the string and pin you are introducing instability. I think it reproduces the effect of a hard blow, shaking loose anything that is likely to come loose under playing conditions. Like Fred, years of concert tuning and the privilege of checking my work constantly the day after have proven this to be a very effective method for achieving excellent stability. ~~~~~~~~~~~~~~~~~~~ Eric Wolfley Head Piano Technician Cincinnati College-Conservatory of Music University of Cincinnati ~~~~~~~~~~~~~~~~~~~ -----Original Message----- From: Fred Sturm [mailto:fssturm@unm.edu] Sent: Friday, November 07, 2003 9:44 AM To: College and University Technicians Subject: RE: Schaff Tuning Levers - slap tuning [bcc][faked-from][mx] Actually, I think a jerking motion is less likely to break strings than a smooth pull. It seems to me it is more likely to break the string free from friction, so there is less stress over less time where the string leaves the pin (which is where most breaks occur). I've always tuned with small jerking motions (hand on the lever, not slapping). I was taught 20-odd years ago that that method was more likely to lead to a stable tuning, and experience has told me it is so. Of course, the key here is _small_, controlled, jerking motions for fine tuning. For pitch raises, a larger jerk right to pitch works most of the time, unless circumstances seem to dictate a quick jerk down first (too often, those circumstances involve a broken string, but it would have broken anyway with a smooth pull, IMO).
