I see what you mean. I understand the general rules about major and minor scales (I-maj, II-min...etc) but I was speaking more of scales and such that aren't derived from the major scale...I.E. scales that have more/less than 7 notes per octave (not including petatonic). What are the rules for forming chord progressions for these scales?

I know Im probably confusing myself and looking at it too hard :).
