OK, I have read enough threads to understand that summer/humid to winter/dry from heating humidity fluctuations are very bad for a piano.

However, I live in Arizona. It is dry all year here (natives start fussing about the excessive humidity when it reaches the high teens ).

In addition, the climate here is such that many weeks (sometimes even months) of the year, it is pleasant to have the windows open 24/7. That is a lot to give up (much less ask non-pianist family to give up) because of your piano. Especially in a small house without a dedicated piano room.

What are the particular risks and dangers to a piano, in a 'stable-but-very-dry' atmosphere?

Thank you!

Stability is the main watch word when we discuss humidity and pianos. However, steadily under 20% humudity makes me nervous. Being from the East Coast, we normally service pianos that have to be baked by an overactive heating system or a fireplace to get this dry, and I don't like what I see in these pianos. To be fair though all of these pianos are in fluctuation.

To get a valid opinion, why not ask a local professional piano tech. his opinion? There are systems that can be installed into your piano that will help.
