percentage %

[David Love]

No, or not necessarily.  The change in pitch will have less to do with
soundboard area than it will with the scaling, specifically the break point
percentages.  The piano strung with the lowest break point percentage will
likely change the most.  That being said, there are differences in the rim
composition that seem to have some influence in terms of the amount of
change in the overall structure.  It seems that pianos with harder wood
construction change (expand and contract) less than softer woods.  Those who
know more about wood technology than I do might be able to expand on that
subject.

I am not sure how to ask this question logically..If a spinet and a 7'4"
grand are in the same room and go through changes because of humidity
fluctuations..will there be a larger percentage of pitch change in the grand
because there is more soundboard to affect than in the spinet?
