[CAUT] Bass bridge, string scale, cantilevered bridge, tone

Grind away a small part of the apron.  You don't really need to remove that
much.  Usually you don't need to remove much.

Jim:

Just a few minutes ago I was looking at an "M" and the bass bridge if it
were brought to the place where the cantilever is attached to the board
the lowest end of the bridge looks like it would be off the bridge root
and rubbing the plate.  What do you do with the last 4 unisons in that
case?

Alan,

Years ago when I had my first class from Del he said that he took a
small grand, reduced the soundboard area by 30-40% (That's what I recall
anyway) reduced the speaking length of the lower bass strings, then
actually had a BIGGER sounding piano! The proof was there to play. It
just sounded like a "bigger" sized piano. The Ms I've done sound more
like Ls, As or Os. But that, I guess, is just my opinion and the opinion
of everyone who has heard them. Can't prove a dang thing...

(AND DON'T WANT TO ARGUE...<G>)

Regards,
Jim

Hi Jim and Ron (and others),

I do not have enough first-hand experience with especially short-scale
instruments that have been recipient of the kind of treatment that the
Brodmann thread was about, namely new string scale with a shorter
speaking
length, longer backlength, no cantilever. But I am curious about what
kind
of tonal change I might anticipate if I were to rescale, say,  a Kawai
GE-1.

Would anyone be interested in describing what would be the likely tonal
result with these changes to this short-scale piano? I know words won't
likely do justice to it, but I'd be interested to hear anyway.

BTW, this isn't idle curiosity.

Thanks.

Alan
