String Question

[David Love]

I think of false beats as occurring due to variations in the speaking length
of the string that are due to poor or inconsistent termination at either
end.  As the string vibrates it occilates back and forth between various
termination points.  That variation creates a series of mismatched
frequencies which we perceive as false beats.
