okay, here goes nothing: in the key of C (for simplicity's sake)- I. harmonic major (ionian b6): C-D-E-F-G-Ab-B II. dorian b5: D-E-F-G-Ab-B-C III. phrygian b4: E-F-G-Ab-B-C-D IV. lydian b3: F-G-Ab-B-C-D-E V. mixolydian b2: G-Ab-B-C-D-E-F VI. lydian #2, #5 (aeolian b1?)*: Ab-B-C-D-E-F-G VII. locrian bb7: B-C-D-E-F-G-Ab when i wrote these out on a sheet of paper (after learning of such a scale as harmonic major), i noticed a pattern: these modes (for the most part) correspond with their "vanilla" counter-parts. but there is a degree that is flat, and the degree starts at 6 and descends as the mode(?) ascends, as you can see. BUT, *when you get to the sixth mode, this pattern leaves us with a b1, which i've never heard of (keep in mind i've only been playing for 2.5 years). even though it kind of makes sense, i just don't know whether it is acceptable or not...so i just kinda put down the best description for that sequence of intervals (R-#2-3-#4-#5-6-7). also, the seventh is already flatted in the locrian mode, and since this flat is flatted again, it's a double-flat seventh (or diminished 7th). this is much easier to remember than those harmonic minor modes!
