I habitually and routinely raise pitch on pianos with 3/4 or full plates by 1/2 tone, a full tone or more Whether the piano is 20 years old or 120 years old, if it can't be brought to standard pitch, today's standard pitch, then it is NOT a viable musical instrument. I am beginning my 39th year in this business and have had no difficulty in applying this standard to every instrument I tune and/or repair. If I am doing a significant pitch raise, I first make certain that all of the perimeter bolts on the plate are tight & doing their job ie; not stripped out in the wood and there are no significant block/back separations. If it is a half tone pitch raise I pull it to pitch in the first sitting, tuning each successive octave several beats sharp of the former from the temperament octave all through the upper tenor and treble. I tune the bass about 10c sharp all the way down check the treble for glaringly bad unison's, re-tune the bass and schedule the second tuning, the "fine" tuning for about 3 weeks afterward. I explain that at this time the piano will stretch out of tune faster than I can tune it, each of the strings stretching at it's own rate. Given some time and playing it will "settle" some and when I return in 3 weeks it will have dropped some in pitch but not nearly to where it was. I will then be able to tune it and get it to hold a tune. When I return I usually get a good finish tune but I also make sure they realize that it should be done again at the next season change to "lock" it into staying at pitch. When it's a full tone pitch raise I pull it up a half tone the first time, return in 2 weeks for the next, to pull it to pitch and again in 2 weeks for another rough tune then back in 3 weeks for a fine tune. </div> <div> </div> <div>Occasionally a few strings break but it's rare, even on old uprights except when the strings are very rusty or someone prior to me got too aggressive tightening down the pressure bar, doing a "15 minute pitch raise"! I pre-warn my customers that it is a possibility. I have had a few over the years where I could not set a temperament because so many strings broke when I was trying to set it. It became apparent that those pianos had a structural abnormality/problem that had developed making them non-viable. </div> <div> </div> <div>I live in Southwest Wisconsin and have tuned pianos for people that tell me that they are confident the piano hasn't been tuned for 20 years, sometimes longer. I have tuned pianos "reclaimed" from the landfill, built-in's where they put the old upright piano in the basement of the newer house, then finished off the basement and couldn't get it out without tearing out the drywall over the stairs, etc. so successive owners "inherit" the piano. </div> <div> </div> <div>So Martin I tune several hundred pianos of or near the age of the piano you write about, only one I can think of has been re-strung most have original strings and hammers. They are used as starter pianos. My question to you is does it NEED restringing, are the pins loose? If the pins are tight a few broken strings are quite normal in a piano of that age. The bolts across the top are from the factory and as long as they are tight, if your pins are tight you should be able to tune it to A-440. All of the uprights I've seen were massively overbuilt and can easily accommodate the extra stress.   </div> <div> </div> <div>Perhaps you would want to consider the hammers, if they're the originals, as a possibility for the string breakage?</div> <div> </div> <div>Mike<br clear="all"><br>-- <br>The secret to creativity is knowing how to hide your sources.<br>Michael Magness<br>Magness Piano Service<br>608-786-4404<br><a href="http://www.IFixPianos.com">www.IFixPianos.com</a><br> email <a href="mailto:mike@ifixpianos.com">mike@ifixpianos.com</a> </div>
