It is in a public high school it has very light rust spots on some strings, mostly high treble. I rebushed keys, reshaped hammers and regulated it a year ago, probably the first regulation it had had since new. I have consulted with 3 different techs at Yamaha, all independently, all unaware of my having talked with the others. I got the same answer, metal fatigue of the strings due to the high tension scale. 2 added that the problem may be exacerbated between the bench and the keyboard. Not only do I agree with the last statement but so does she, the vocal director, admits that she has a very heavy touch. However I have also had strings break when I was tuning, not while I was tuning them but after I had moved on and was a couple of strings away, no longer even on the unison. The director has had bass strings break while playing, 2 last year, one so far this year.  <o:p></o:p></span></font></p> </div> <div> <p class=MsoNormal><font size=3 face="Times New Roman"><span style='font-size: 12.0pt'> <o:p></o:p></span></font></p> </div> <div> <p class=MsoNormal><font size=3 face="Times New Roman"><span style='font-size: 12.0pt'>My initial inclination was to look into rescaling it but after talking with a friend who has more experience with re-scaling than I do, perhaps that wouldn't be the best avenue. It was his feeling that perhaps the 30YO hammers may be the culprit. restringing may solve the breaking problem in the immediate future because it's new wire but with the old hammers the breakage will return before long. <o:p></o:p></span></font></p> </div> <div> <p class=MsoNormal><font size=3 face="Times New Roman"><span style='font-size: 12.0pt'> <o:p></o:p></span></font></p> </div> <div> <p class=MsoNormal><font size=3 face="Times New Roman"><span style='font-size: 12.0pt'>The piano, as I understand it, was designed primarily as a smaller stage piano, a concert instrument if you will. The school uses it 4 hours a day minimum in a classroom setting, very hard use. As it was put to me what they need with the re-string is a 99% classroom instrument and a 1% concert instrument.  <o:p></o:p></span></font></p> </div> <div> <p class=MsoNormal><font size=3 face="Times New Roman"><span style='font-size: 12.0pt'>I have the great good fortune of the Superintendent of Schools for this district having been a former elementary music teacher and he worked his way through college doing "piece" work for a piano tech.
