Well, I didn't read the GP article, but I think I get it. The chromatic nature of the melodic minor gives you all the possible alterations of the dominant.

Making it minor also gives you the half step from 2 to 3. 7 to 8 is the alteration either melodic or harmonic minor gave you. 7 to 8 is the same as #5 to 6 when looking at it as based on la(6).

Add this to the lydian and you get, for example, in C: C Eb E F# G which,if you call it Gb, is some kind of hybrid major-diminished chord (or tone cluster for the Piston crowd). Play that on an organ with a leslie and it's beatnik heaven.

You've got to know your limitations. I don't know what your limitations are. I found out what mine were when I was twelve. I found out that there weren't too many limitations, if I did it my way. -Johnny Cash
