In this you are correct me thinks... but then ETD's are
stretch octaves directly, and the stretch of other intervals
becomes dependant upon this... so much so that I wonder if
anyone has ever even thought about doing things the other
way around. Funny too when you come to think of it... the
stretched tuning curve results in basically no two octaves
having the same set of beat rates for each relavant type,
nor the same compound beat rate for that matter.

The distance between an octave has always been troublesome
anyways. The desire for a perfect 5th gets like really in
the way of any and all shemes for spliting it up when it
comes down to it.... so why not split the distance between a
perfect 12th up into 19 evenly spaced semitones instead ?,
Following this scheme up and down tuning by 12th types
instead of octave types yeilds a slightly different octave
curve (if you first want to view a tuning from the
perspective of octaves) in the treble, with a more tense
stretch in the C5 - G6 range, and much reduced stretch for
the higher notes.  The net difference from traditional
octave priority stretch is not really very much, but in the
bargain you get perfect 12ths... which seems to contribute a
bit to higher note sustain.... sort of in the sense of the
duplex idea me thinks. In any case there is an aural effect
created by tuning this way that you dont get from tradition
tuning curves, and its quite pleasing to the ear.

In the bass.. I just look at both the 3:1 12th, and 9:3
12th, and stretch the bass somewhere in between so as to
insure that the octaves are at least 6:3 or wider. Typically
this results in an A1-E2 9:3 12th type that beats at about 3
bps narrow, while the 3:1 is about 0.5 bps wide.

Sigh... I really do wish you would get over this nonsense
Bill. I mean even if you are 1000 percent correct... (and I
am not saying you are)... you demean yourself so with this
tact. Its really quite embarrassing to witness.

Seems like a good path to walk down.... so far I havent
found any bunnies hopping around on it yet...  I have
spotted a few funny coloured mushrooms tho :)
