Kristinn, I'm not an engineer, so I don't know why the bass changes (or doesn't change) in tandem with the rest of the piano when the humidity changes. I just know it's pretty common around here. I'm responding to mention another possibility. Is the piano a vertical? If the weight distribution on the four casters is different than before because of the floor of the room, that can have a rather dramatic effect on the tuning. I am tentatively planning on demonstrating this at our next chapter meeting.
