@Danny Guitar Rogers - Thank you for all this man. I think I am somewhat comfortable with converting to minor across all the chords, and I have all the formations down. Where it's tripping me up is whether to play minor formations FROM the: a) ii chord b) relative minor And in your chart you sent me you'd hand drawn, you've done both too - which is confusing. Here's an example. Bar 3 of "How High the Moon" moves to a G-minor chord, which is seemingly the ii-chord within a ii-V-I moving to F-major. Given that the key center is F-major... should we should use the relative minor of D-minor, and play D-minor formations? The reason I bring this up is because not all D-minor formations sound great over the G-minor chord. For example, the D minor formation starting on A (second inversion, in my head)... doesn't sound that great over the G-minor chord because it has a C#. Does that make sense? When I watch this video of Armin over "How High the Moon" - he's solely using relative minor: https://www.youtube.com/watch?v=FPzzgxAFnQ4&t=334s And so over the G-minor chord in bar 3, he advises to play D-minor formations. As I mentioned above - not all of the formations sound good over this G-minor chord. And in your drawing which you kindly sent, you're playing G-minor formations over the G-Minor chord in bar 3... even though it's the ii-chord. But Armin *isn't* playing this. Do you see where I'm coming from? Armin suggests using the natural minor over all. So in G-Minor, he's playing D-minor. But when I run through a ii-V-I in F-major using D-minor formations... not all of them sound good. I guess it leads me to ask.... is it situational? Or should it always be related to the major key's relative minor? I seem to prefer always playing formations from the ii-chord, they just sound better to me than converting to the natural minor. That way, when I see the G-major chords in bar 1 and 2, I'd personally be inclined to think of the ii chord (A-minor) and play formations in A.
