Robert,
I enjoy your website and your videos. Thanks so much. My piano is a Baldwin acoustic upright and I have it tuned regularly. But now I have a new piano technician and he is suggesting I add a humidistat to the inside of the piano to regulate humidity at all times. He says this will cause me to not need regular tunings anymore. Does this make sense? I've never heard you speak of such a thing.

Sincerely,
Laura

Your tuner gave you some good pointers. In fact, stabilizing the soundboard will help with tuning stability particularly in environments with wide swings of humidity. Although I live in Southern California with a semi-arid climate, I have a Dampp-Chaser System on my concert grand which helps keep the tuning stable. However, all pianos will still require tuning on a regular basis, particularly if they are played a lot. The Dampp-Chaser System just prolongs the life of your tunings.
