31:19) These are very important over the next several minutes, as I was thinking (the V of the V in a Major key of the parallel axis shift of a legitimate natural minor key progression I've been composing) Not truly Aeolian, but of a reverse engineering approach. I can see maybe another angle as this may not actually work since this only replaces the half-diminished Locrian chord. This would basically move the flat five up to a five and the minor third up to a Major third. Hmm, I just thought of something else. What about voice leading.
2:50 … I’ve personally never seen inversions notated this way; could get pretty difficult to read, eg iV could look like a Subdominant reference, rather than a first-inversion Dominant … I was under the impression that little “a, b, c” superscripts were used for 1st, 2nd, 3rd inversions (American?) … ?! Cheers.
I have seen the lowercase i notation used so referenced it but as you suggest it can become confusing in certain situations. Because of this I tend to use slash chords. I have heard of the lowercase letter notation but I'm not sure of it's origins.
