A constant humidity level of 45% is critical for protecting your piano and making your tunings last. Unfortunately, here in Minnesota we have one of the worst climates in the world for pianos. It's not uncommon to see humidity readings of 10% during the winter, and over 80% during periods of the summer.
For a piano, this kind of change is extreme and not only affects the tuning, but can cause additional problems
with loose tuning pins and cabinet parts, soundboard cracks, string rust, action part noises, warpage, looseness, and sluggishness. Even with air conditioning and furnace/room humidifiers, control efforts are only slightly improved as is evident in the thousands of humidity readings I've recorded over the years in a wide variety of homes and institutions.
