Another question regarding Well Temperament

[Douglasmahard@AOL.COM]

Hi all,

Thanks to everyone who replied to my last question regarding well 
temperament.  Seeing how the last discussion remained quite civil and very 
informative on this subject I would like to tempt fate again with the 
following:

In Owen Jorgensen's book Tuning the Historical Temperaments by Ear he states 
on page 431 "In direct opposition to equal temperament, the purpose of well 
temperament is to allow harmonic color-change through modulation.  Only when 
the tones are not equally spaced can there be different effects in the 
various tonalities.  This latter quality cannot exist in true equal 
temperament in which all tonalities have identical effects except for 
increasing or decreasing beat speeds.  In the number of proportional beat 
triads, well temperament is superior to equal temperament and also most of 
the meantone temperaments.  This gives well temperament a certain rhythmic 
harmoniousness."

I was with him up until the last two sentences, then came "proportional beat 
triads" and "rhythmic harmoniousness."
Anyone want to try and educate me on proportional beat triads and rhythmic 
harmoniousness?

That last ones a mouth full.
