So if the piano is 20 cents flat, you are only raising it 6.6 cents above its normal place. That shouldn't create any problems. If the piano is 100 cents flat, maybe a third pass is in order so as not to overdo it. On very old pianos with compromised string condition you might need to make a judgment call. On most pianos there won't be a problem. It may be archaic, but it works.

On small spinets, reduce the numbers by 5% each. Do unisons as you go." David, I must take exception to this technique! Although, it will work most of the time on most Olde Uprights and Grands, there is always the exception. This technique is archaic, to say the least. There are better ways. The 32% in the upper treble will most likely get someone in a world of hurt! Most strings, in that area, are already at/above 50% of their breaking strength!!! You raise it another 32% and strings will break, IMO. I've done some studying on the subject and wrote an article for the PTJ, in Dec. 1999. Regards, Joe Garrett, R.P.T.
