I have several videos based on the subject of where to put your piano. But now I’m going to address specifically putting a piano in a basement. The issue is about the extremes of temperature and humidity the piano may be subjected to. This is a concern with pianos going anywhere. Pianos thrive in a stable environment of around 45-50% humidity. Minimal changes of temperature or humidity are ideal. It’s best to treat the room. Basements provide special challenges. The good news is that basements can be somewhat stable in terms of temperature because of the geothermal effect.
However, many basements can be extremely moist, and if you have any issues whatsoever with basements ever becoming wet, I would not put a piano down there under any circumstances. If it’s impossible to treat the room with dehumidifiers and possibly even humidifiers, the next best thing is a Damp-Chaser system which sits under the piano or behind the piano on uprights. They provide stability by either heating up rods to take out humidity or even adding humidity from a water tank. This is a possible solution if treating the room is not practical.
To recap, the ideal environment is to put the piano in a room that is stable in regards to temperature and humidity. If you’re in a room that is not particularly stable, try to treat the room. And lastly, if you can’t do either of those, at least get a Damp-Chaser System. Once again, I hope this has been helpful and thank you for joining us! Robert Estrin at LivingPianos.com
