[pianotech] Petrof vertical string breakage.

[Gerald Groot]

Watch him play.  Find out how hard he plays and what he plays to make it
break.  Don't say anything about suspecting that it might be HIM that is the
problem because he may just set back and not play as hard then.  Ask what
happens at that point when it breaks.   Chances are, my guess, would be that
it is him that is the problem in one particular song that he likes to play.
I run into that frequently at my college when one particular professor is
practicing the same song over and over and over again for a recital or
concert.  She's broken the same strings on the same song yet, when she
changes songs, the strings stop breaking.  She has a VERY hard touch and
this is what is causing it and she knows it.  I've tried replacing with
smaller and, larger diameter wires. It makes no difference in her case.

I have been servicing a 2001 Petrof vertical since 2006 with no problems. In
Aug 2010 my customer called and thought a string may have broken. It had and
I replaced the string (#14 1/2) and tuned the piano. I tuned the piano again
in Jan 11 & May 11 everything looked good (by the way, he is the only player
and plays only classical music). I just got a call that a string has broken
again and he thinks it may be the same one. 

 

This piano has agraffes throughout. Any thoughts or suggestions? And if it
is the same string should I go with one size smaller?
