"It starts out that way"? You mean that when you're stringing you pull the tension to a half-step over pitch? Please clarify.

It starts out that way, but by the time I'm done chipping, it's down significantly. I start my chipping with the first note in the tenor. I chip one string of that note a half step high. I then chip a major scale, one string only, all the way up. I then chip the second note in the tenor a half step higher than the first note, and again doing one string for each note, chip a major scale. (of course the?3rd and 7th note of that scale are already "tuned". I then chip one more string on each note, and finish chipping the third string. I then chip the bass strings. I've never actually measured the first string in the tenor, but?after I install the dampers and push in the action, I usually wind up doing about a?50% - 60%?pitch raise, with the?SAT set?25 cents high. I wind up with good, stable tunings. As far as what Noah found, whoever restrung that piano either didn't know what he was doing, or misunderstood the difference between a half step and and a whole step. I've run across Asian pianos that were 25 cents high right out of the box. They must have started higher than that when they left the factory,?but I'm sure it wasn't a whole step higher.

"Beyond it's elasticity" means that the string will now break. Overpitching a string will not cause false (real) beats in and of itself unless there is some bridge involvement. And chipping a piano even a half-step high seems to be way more than necessary. I have typically chipped the piano about 25 cents sharp, watched it fall, then chipped it again 10 cents sharp before actually tuning it, with very stable results.

I don't think this dealer?understands what is happening to this piano. Is he telling you to keep it a whole step high because he doesn't want to pay you to do more than just a tuning, or does he think customers?won't notice. In my opinion, he is not being honest with him self, much less his customers.

A3 was B3, so i tuned it to A220. about 3 notes later i felt really weird, so i informed the boss what was going on and was told to tune it where it was at. it had just received new strings. well that made it easier to tune, but i mean, ive never heard of tuning a piano a whole tone sharp.
