Hi all: Twice this month I have come across pianos which hum a harmonic 2 octaves and a seventh above the fundamental when the key is released. In both cases it was only one of the three strings which leaked the harmonic, in both cases an outer string. I checked and re checked the string level. Any ideas? one was F# 2 on a S&S B, the other was D3 on a S&S D. I have tuned the D for years- this just showed up. --- David Graham <dcgrpt@earthlink.net>
