Seating/false beats

Hi,

I must admit that all of this talk about "seating" strings on bridges
bothers me somewhat.

There is no question but what this is a necessary thing to do from time to
time, and under varying circumstances.  On the other hand, I've seen
countless pianos with the strings driven halfway to Baltimore - literally
half the string diameter imbedded in the cap.

Susan's questions speak to these issues.  My thoughts:


>If, as seems possible, hard blows are enough to cause the strings to ride up

Yes, for reasons others have clearly stated.  The string must maintain
_proper_ contact with the top of the bridge.  Also, the more consistency we
can maintain in the piano, the less variation there will be.

>Would it be better to consider who is going to play the piano next?

Sometimes - for most situations, this is not a major issue.

>What if
>the next performer is heavy handed, and will drive them right back up?

Some may.  But, if the piano is well maintained, the effect will be
minimal, if at all noticable.

> Will
>a pianist's unseating them trash our unisons at the same time?

Usually, while an individual pianist _may_ create this condition, our
unisons are much more likely to be trashed by poor hammer technique.
Joel's note about changes in a given piano during the course of _very_
heavy use (in this case the Van Cliburn competetion, although, I have noted
other instances of similar conditions under similar use) makes this point.

>When we do
>whole-hearted test blows, do we drive them back up ourselves?

I seem to be, in yet again another way, a dinosaur here.  I tune _very_
hard.  Very hard, indeed.  Not everyone needs to, or should, perhaps, do
this.  Since so much of my work has been in situations where breakage,
slipped unisons, etc, have been unacceptable,  my own sense of this is that
I would much rather have something slip, break, knock, whatever, while I am
there, rather than to read about it in the next day's paper.   Obviously,
this also has to do with my own ego - I hate going out on stage to "fix"
what "should" have been right to begin with.  (read:  "Hi, I'm Horace, and
I'm a piano tuner...)

> What happens
>to the bridge top and pins when we seat -- unseat -- seat, over and over?
>

My point, exactly.  Unless _great_ care is taken, a good deal of damage can
be done very quickly.


More later.

Best to all.

Horace
