This is a multi-part message in MIME format. ---------------------- multipart/alternative attachment Hi David, I think that if you would measure the octave above each pair after you = have tuned each string with the SATlll or any other ETD,you will find = that there is as much as 20c difference in the pair on another partial = that is causing the racket. This makes the piano untuneable IMHO and replacing the set is the only = way to go. Re scale too. I have a G1 that will be going through restringing in Dec for this very = problem. One thing that I will try just before taking the strings off is to let = the string down a fifth to an octave and use the notes hammer to try to = move the winding by pounding the note 10 to 20 times very vigorously. This works on dead strings to bring some life back into the string so I = am going to give it a go.

It's got me = stumped. I'll include some details in hope I can get a good answer. I tuned two Yamahas for a customer in her teaching studio. One piano = was a Model U-11 Ser # T 121496 and the other a G3 Ser # 1098046. The = grand had two pedals and a data plate on the inside of the case so I am = assuming it was mfg. in Japan. I did not attempt to tune them together = as I know the scale is different and the client wasn't interested. Both = pianos had the same problem. =20 Neither piano had been tuned in two years and the client tried to = convince me that it was a "new thing" that piano manufacturers had = "just" started recommending a piano be tuned every six months. = Amazingly the lady was blessed/cursed with an uncanny ear that could = pick out every false beat and nuance. She called my attention to the = low bass in each piano. Neither piano sounded right. I did all the checks and all beats were correct. The octaves just = didn't sound right on the on the first 6 or 7 notes. I figured I would = just tune them as clean octaves, but I could not get the lower notes in = line. The partials were beating so fast either way, the notes sounded = horrid with the rest of the piano. Is there a possibility the scaling is off? Tapping down the strings = doesn't help, twisting either. There is a bit of rust on the grand, but = the other is clean. I'm kind of at my wits end. Am I missing anything? = =20 Mark Wisner, you told me you read all the Yamaha stuff on Pianotech, = would you care to comment?
