[pianotech] Petrof vertical string breakage.

When a string breaks at the pin or hitch pin, it's usually a weak string. When it breaks at the agraff, it's usually hard playing. Do you remember where this string was broken? As Jerry mentioned, the guy might be practicing a particular piece of music where that note is hit repeatedly. One suggestion is to check the voicing on that particular note. It might be a little softer that the others around it, and the pianist is hitting that note a little harder to create a louder sound, this putting more strain on the string.

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?
