Here’s a sample of what the piano recently sounded like:
***
My beloved childhood Sohmer upright met its demise after decades of exposure to New York City weather extremes. I played it at my mother’s 100th birthday celebration this past October, and it was without doubt, ready for the scrap heap.
In my riveting phone conversation with Sam Bennett of Piano Works, Duluth, Georgia, I was fortunate to amass a wealth of information about how to sustain and maintain pianos in high humidity parts of the country, and what specific measures can be taken.

Russell Kassman, Purveyor of Fine Pianos in Berkeley, CA also chimed in with some valuable ideas on the subject.
“Certainly, a simple hygrometer can be very useful in monitoring the conditions in a room.”
MY COMMENT: I own a hygrometer that reads the temperature and humidity here in my Berkeley apartment. So far the readings are stable as shown below.
Mr: Kassman: “The more stable the environment is (both in temperature and humidity), the more stable tuning will be. Pianos are living, breathing instruments and when it is humid, soundboards and rims expand, often causing pianos to go sharp; when it is dry, pianos often go flat. Heat makes metal (steel strings) expand, cold makes steel contract. These fluctuations cause great instability with unisons.
“While there is nothing wrong with a properly operated and installed “damp-chaser” system, I prefer to control the room temperature and humidity levels. We keep the shop at 42-47% humidity and 70-72 degrees. To do this consistently requires a delicate balancing act (and quite a bit of money to PGE): Our HVAC system (heating and air conditioning) is capable of removing humidity but not adding it. So, we have several humidifiers, strategically placed, to add moisture when necessary. However, a home user doesn’t have to go to this expense to add moisture: a simple (cheap) way is to purchase a “cool air vaporizer” from any Walgreens and run it when the needle of a hygrometer drops below 40%. Usually, running it once a week is more than sufficient to get the needle into the desirable percentage, but when the heat is on in a home, it may be necessary more often. To remove moisture, one just has to turn on the heat (in most homes today – not the old STEAM heat, which causes other problems).
“If one wants to purchase a self-contained automatic humidifier, such as ours, there are MANY on the market and I can’t say one if necessarily better than the other. Home Depot carries (online) a very nice selection of them, and their cost and size would be based on the size of the room it is conditioning.”
