Scale tension

Hello,

I think that some part of the breaking string problem is the unison tuned
without any warmness , energy and opening.

The pianist can't have the sound he wants and try to play harder to move
things. May be there is too a physical effect because the strings are given
too much energy at the attack of the note.

The shape of the capo may well be a cause too.

And plastic on the top of the hammers seems to work well, thank you Mr.
tooner x...

Just changed 14 treble strings on a B - was there 1 month ago and changed
12, the strings are 3 years old, the capo had been "shaped" with linen and
is very flat, the Renner hammers have been treated with plastic in the 2
last sections.
I had to needle to death the base of the hammers to restore some power in
the crown, the last time I mostly needle the top regions and of course,
under the heavy playing of this professional pianist, they harden soon.

But finally, I got it (I am the hero !)

Cheers, a little glass of wine for the job well done.

    I think soft hammers break more strings than hard ones.  Why?
    Because the pianist wants a certain sound for the fff climax of the
    piece.  If the hammers are soft, he/she has to hit the keys harder.
    Still not enough sound, hit them harder yet.  Bang!  It happens all
    the time.

  I do agree that a pianist wants to hear a loud sound, and he will play
hard, but I don't think it is necessarily the condition of the hammers. The
same pianist who broke strings on his B, didn't break them on the D in the
concert hall, either before the concert when he practiced, and during the
concert. And he played the Rach 3, quite a loud and boisterous piece, to say
the least.

  I think part of the problem is the playing technique. Some pianist have a
technique that will cause strings to break, regardless whether they are soft
or not. A very good jazz player in St. Louis had reputation of breaking
strings. It was something in his attacking the notes that caused strings to
break. A lot of fundamental churches break strings, because they constantly
play hard. So I don't think it is all related to the condition of hammers.
