<HTML>Hey list! Something new after 24 years with my head st= uck in other folks pianos.... Here's the problem: I tuned a Kimball Console today (the piano is 35-45 year= s old). Both E7 and F7 sounded their own pitch plus the pitch of the other. = On closer examination I discovered that, in fact, the neighbor was vibrating= as if it had been struck even though it hadn't. Anyone seen this before? Any ideas why it might be happening or possible cur= es? Thanks for your thoughts. will wickham</HTML>
