Really ?? I suspect that there is another way of looking at
beats then counting the beat rates of individual
coincidents. To be sure in this perspective the notion of a
beatless 4 octaves is meaningless... or what ? In Virgils
own explanation of the natural beat he seems to refute the
usefullness of tuning by octave types per se. I would think
his perspective on 4ths then is likewise not the same as the
actual difference in HZ between the 3rd and 4th partials in
fourths.

I would like to read someones notes on Dr Sandersons class
for sure.
