"Or change in wire size.
McFerrin cites variation in wire diameter in a single string as a cause for false beats."

That's what I meant - change in diameter within one string - not a change in size from note to note.

  McFerrin cites variation in wire diameter in a single string as a cause for false beats. The smaller diameter yeilds a different a localized different tension which yeilds a secondary set of partials.  I've not heard that a change in wire size alone would affect false beating one way or the other... but it wouldnt suprise me that this too would end up happening or not on a random basis.

    Farrell replies
    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.


  Thats the going theory... sideways micro wobble allowed by both a loose pin in combination with a crushed notch edge that leaves the edge drop off behind the string.  Only problem is that there is no occurrance of false beats  in all to many instances.
