So in order to get the instrument stable again, you have to keep retuning it as soon as it goes out. Over a period of time, the old bend will relax and a new one will form, causing the string to go out of tune. When you drastically change the tension on that wire, those bends end up in a slightly different place. The main cause of this is that the wire forms bends around several bearing points on its path between the tuning pin at one end and the hitch pin at the other. As MMazzon said, stability will definitely be a problem at first - the piano will go back out of tune a lot faster than normal. It'd be nice if you could back up your answer by some kind of credibillity / source material.Įverything else being all right, it's entirely possible to bring the piano back up to pitch after it has sat untuned for a long time. So, long story short: given a piano, and not tuning it for a very very long time (everything else to be alright), will it be untunable after it reaches a certain degree of detuning? If so, how does this happen? There isn't much room for the different forces to work opposingly. Of course one could argue that the frame goes out of shape when it's not stressed evenly any more, but that seemed unlikely to me, because all the strings (and all the force vectors applied to the frame) point in the same direction. Things go out of shape when there is too much tension applied, not too little. However - now that I think about it, I don't really understand it any more.
When I asked why, I was told that the frame inside the piano goes out of shape when the strings lose their tension, and that this process was irreversible. I've been hearing a hearsay all the time that if you didn't tune a piano for a long enough period, and it goes out of tune too much, it couldn't be tuned any more at all.
