On some old uprights, I've encountered a phenomenon in which the middle string does not damp while the outer two do. This may happen on individual notes but sometimes on many notes. Recently I replaced the damper felt in an old upright, and the middle strings kept right on ringing (as they had done before), certainly throughout the mid range of the piano. Was the piano designed this way to make it seem more alive? I don't prefer it that way. What is the suggested fix, if there is one? On some occasions on an individual note like that I have sanded the damper felt so that it is thicker in the middle than on either side. It works, but it would take a fair amount of time when many have this characteristic. Thanks for any input. Arlie D. Rauch Glendive, MT
