An aural tuner generally goes for an off shoot of one third above the amount that the pitch is flat. If it's 5 beats per second flat to the fork (20 cents) then you should tune it just less than two beats sharp. ( eight cents would be two beats per, and you would want a little less than seven.) You probably would do best to follow the same procedure with a SAT. In the treble, anyway, if you are tuning unisons last. If you're tuning unisons as you go, use the pitch raise calculator. I think that you'll find that the method you have found will work on some pianos and not on others, but if you find it to work consistently, let us all know. On most pitch raises, we're just trying to get it close enough that it will be really stable on the second pass, You cannot do a fine tuning and a pitch raise at the same time. Period. Better people than me told me that when I was just starting out, and I've found it to be true. ----- Original Message ----- From: "Phil Bondi" <tito@PhilBondi.com> To: "Pianotech List" <pianotech@ptg.org> Sent: Tuesday, December 12, 2000 4:22 PM Subject: An Aural Adventure solved? > Recently, I posted a note here telling of my inability to have A4 come up at > 440 after tuning a piano..I explained my aural tuning sequence..i'll spare > you all of that and NOT repeat it again! > > I had a few private responses..but here is what I have found out since that > post: > > When finding out where A4 is when I start, I am now doubling that amout, > offsetting the machine(SAT), tune A4 to the offset, and aural tune from > there. > > Result: > > When I finish, A4 in on the $$$. > > In other words, if A4 is at -4.8 when I first measure it, I am adding 4.8 to > bring the number to -9.6...then offsetting..then set A4 from there. > > I did this procedure today with a Yamaha C7..and I have had the same result > with some lesser grades of pianos over the last 2 weeks. > > I am not convinced that this much offset is really the way to go for an > aural tuner setting A4 from the SAT, but my results have been great since I > started doubling the amount. > > I would like to hear from the strictly aural tuners on how they get A4 to > end up at 440.
