ETD Unisons was something else

Hmm... neat stuff here... Couple questions below and one comment for thought.

I have thought along those lines "aurally" for many years, but of late I begin
to wonder if thats something I can absolutely depend on or not. Throwing an
second note into the mesh (as in an Octave) can change that loudest partial
picture, and throwing two in can change it more. Then there is always this
buisness of the progression of tenths.... thats a what.. 5:2 coincident... so
seen from the bass side unison  its desirable to have that 5th partial clean no
matter what else is going on... which of course doesnt always work well with
the other conditions. Still the *loudest* partial is gonna have to be one of
those things you take into consideration.

Not quite sure I follow you here. What do you mean "beat free", and wouldnt the
partials below beat "wide" instead of "inside" ?

Again I am unclear on your meaning.... care to expound a bit ?
