What does "harmonic" mean in "harmonic mean"?

0There is some discussion on why the harmonic mean is called *harmonic* on [this page](http://jeff560.tripod.com/h.html) of Jeff Miller's [Earliest Known Uses of Some of the Words of Mathematics](http://jeff560.tripod.com/mathword.html). – 2012-07-26

0Also, I've edited the title to distinguish this from the question about harmonic functions. I tried to keep the pun I thought you were going for. – 2012-07-26
