Bridge Seating

[Farrell]

"...false beat is ... caused by changes in either the speaking length or a change in the tension of the string."

Or change in wire size.

"Does a loose bridge pin create changes in tension or changes in the speaking length of the string?"

I certainly don't know for sure, but I've wondered the same thing and made the assumption that both these things are likely culprits.

  I have this piano where every single string is false. I know it is not the bridge pins because there are no bridge pins. Another form of clamping the strings to the bridge is being used. ( I'll leave you to imagine what that might be.

  Now, as for the cause, we have to start from the very beginning. A false beat is two different frequencies produced by the same string. To have two frequencies produced can only be caused by changes in either the speaking length or a change in the tension of the string. What is the actual mechanical link between a loose bridge pin and either of the above causes? Does a loose bridge pin create changes in tension or changes in the speaking length of the string?
