Hi, Pretty common problem. Here in Virginia, if you look up the definition of "false beats", they usually have a picture of a Wurlitzer spinet alongside it. There are lots of reasons known and suspected of causing false beats in any piano. But, I have my own theory about them in lower end pianos. Quite often, I am called to tune a spinet that has not been maintained at all for many years. "The grandkids are taking lessons and they are over here every afternoon. So, I thought I'd get it tuned even though its only been 20 years since little Suzie our daughter was taking piano lessons!!" By the time I see this piano, it is often 65 to 100 cents low in pitch. Often I do not notice false beats (especially in the 5th and 6th octaves) at that time. But, after pulling pitch up to at least near A-440, false beats are all over the place. I suspect that the bends in the wire at the bridge pins are being pulled into the speaking length of the string. And, I further believe that this bend permits or encourages or causes the wire to vibrate irregularly; i.e., yielding false beats. Its not just Wurlitzer's, of course. But, since we see so many of them, it would be natural to make the association. Just a hunch.

A whole lot of my customers here in central Texas have them. Thanks D. Powell ________________________________________________________________________ Interested in getting caught up on today's news?
