But there is a correlation between the 'height' of the interval in the
series (ie, eg, 5/4 x 3 = 15/12) and the difference tone, so there
could be a connection...

hi Paul (for when you come back), or others. I can't locate the old thread, but thanks for suggesting the above spelling for the chord d4- f#-b4-E5. I don't...	traktus5	Jun 20, 2006 5:53 pm
Hi Kelly, ... Exactly! ;-) ... The tetrad am : bm : cn : dn has the property that dn/am = n/m if and only if a = d. (Here juxtaposition means multiplication:...	yahya_melb	Jun 22, 2006 2:23 am

Hi again Kelly, ... [snip] ... Errata: in the above, I should have written: 45/36 = (5 x 9) / (4 x 9) = 5/4 80/60 = (4 x 20) / (3 x 20) = 4/3 80/36 = (4 x 20)...	yahya_melb	Jul 2, 2006 8:19 am
