A customer called me the other day who has an old upright piano, a fairly nice one. But it has one unusual feature--either that or she is not telling me everything. The nut which adjusts the damper pedal tightens itself over time to the degree that the dampers stand off from the strings, and the sound just rings. Is this really possible? She claims no one tampers with it. But every visit I adjust it so it works properly, and my next visit it is screwed down so tight that the dampers are off the strings again. Anyone else experience this? Can you explain it? I can understand a nut loosening, but tightening by itself baffles me. Anyway, it's time to loosen the nut again! Arlie Rauch Glendive, MT
