The reason is that the strings have not seen = this much tension in a long time and bringing them up to the correct = pitch too far all at once will result in the strings stretching (a = normal reaction) and the tune going flat immediately. For that reason = the first tuning (pitch raise) involves tuning each string slightly = higher than the final result to take advantage of this drop in tone. = This is called overpull. By the time the second pass is made to fine = tune the piano, the strings will have settled and fallen back close to = where they should be for the final tuning. =20 With this in mind, if we tune only up to the proper pitch once and = not beyond, the strings will stretch and the piano will be flat when = finished. I explain that I wouldn't get out of their driveway before = sour notes would be heard. =20 I find it helpful to show the customer on my Korg tuner I use for = pitch raising, the needle and scale and the relationship of all these = elements. Drawing a picture may be helpful also. =20 Mike Kurta ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
