Hey Mike - Can you help me sort out minor ii-v-i? I originally learned to negotiate this prog 1 way - but Mark Levine's Jazz Theory book has a different approach. The way I originally learned - My 1 minor chord is natural minor from the 6th degree of the relative major key and I play natural minor scale over it. From there I derive a m7b5 as the ii chord and play locrian over that. And the 5 is actually the 3 of the major (a minor)- so to make it perform the dominant function I raise the 2nd & 3rd giving me the 7th mode of melodic minor. The Mark Levine method is to treat the minor ii-v-i as coming entirely from melodic minor but different keys for each chord. So if my 1 chord is C min/maj - I play the C melodic minor scale over that. My 2 is D half diminished - I play the 6th mode of F melodic minor over that - and my 5 chord is G7alt - and I play the 7th mode of Ab melodic minor over that.
