Humidity and Pianos
By John A. Tuttle

Hi All,  I just finished uploading another new web page to  It's about "Humidity and Pianos", and was written
by Craig Brougher.

Having lived here at the Jersey shore for my entire adult life,
I really thought I knew all there was to know about humidity and
pianos.  I was woefully wrong.  In the article, Craig explains 'why'
problems raise their ugly head when a piano is moved for one type
of environment to one that is very different.  But what is even more
interesting is that he also explains what one can expect will happen
and how to most effectively correct and adjust for the changes.

One little tidbit that I picked up on is that since moisture in has
mass and takes room, it "compresses the pores of the wood and they
will stay compressed".  At first, my inclination was to disagree
because for years I used water and steam to raise dings in piano
cabinets when I refinished them.  However, thinking about it honestly,
I had to admit to myself that those dings never came all the way back
up.  They only came up about 80%-90%.  To make the surface very flat,
I still had to sand the surrounding area.

So, for those who are truly interested in picking up some excellent
information about humidity and it's adverse effects on a piano, I
highly recommend this article.  It will raise an eyebrow or two... ;-)
(I said to myself, "Hmmmmm", more than a few times...)

(About a mile from the Atlantic Ocean, and, for the sake of all
my friends, acquaintances, and customers who own a piano and live
on the East Coast,  I'm really hoping that the hurricane tracks
'way north or stays out at sea.)
