Re: The 3 4 5 cube-continued

I can't be affirmative on "3 5 7 cube" for I had never read on mentionned
theories. I can be only interrogative.

Could you consider distinction between "approximately good" and
"structuraly good" about chords ?

The fact that 35 and 115 could be "approximately good" in
well-fitted-(3,5,7) temperament is obvious.

Let be a cube 1,a,b,c,ab,ac,bc,abc. If errors Ea,Eb,Ec are small, error on
abc can't exceed Ea+Eb+Ec (on worst case).

But is the 115 harmonic "structuraly good" in
(7)-113-57-115-(29)-117-59-(15) ?
