Thanks to everyone for your suggestions on eliminating the "zing". Our PTG chapter members put our heads together and still couldn't eliminate the mystery noise. We removed the damper wires on both sides of the bichord (the highest one before the break), there is plenty of clearance between the string and the bridge pins and bearing bar underneath, the strings have been replaced, the bridges and notching look good, the string's bridge pins are tight. It seems very unlikely that the new strings would be flawed too, so we could find no reason for this noise. It is a Grotrian grand and has a beautiful sound with all types of playing except this one note on heavy playing. I began to suspect the bridge cap, but this sound is metallic. We all agreed it sounded like it was coming from near the back of the piano. The only clue left is when we plucked the string upwards it didn't make the sound, plucked sideways it did. It's beginning to seem the only solution is just stop playing fortissimo! ======= Email scanned by PC Tools - No viruses or spyware found.
