[pianotech] Petrof vertical string breakage.

[Laura Olsen]

Hi Al,

Chances are extremely good that it's not the same string.  I can't see how one size smaller would help.  A smaller diameter wire under tension designed for a larger diameter  would break sooner, wouldn't it?  Check your hammer shape and don't think that classical music is any less aggressive than any rock or pedal pumping gospel!  You'll need more information to diagnose a problem.

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.
