Advanced Little modal idea I just had

[Ids Schiere]

So basically you know how you can find chord within chords.

For example if you take an Am6 you also can use that chord as D7, D9 and F#m7b5 which also means you can use the same scales over them to increase your options

For example
Am6: A harmonic minor, A melodic minor, A blues scale
D7/D9: D phrygian dominant, D
dominant diminished(D# diminished), D double harmonic major, D mixolydian b6
F#m7b5: F# Locrian, F# locrian #2

Now if you can use all of these over the Am6 but you will have to name them a little differently
D Phrygian Dominant-A Locrian 6
D dominant diminished - A diminished(symmetry and such)
D double harmonic major - A oriental(but you're probably better off using A hungarian minor instead which is the 4th mode of E double harmonic major)
D mixolydian b6 - A Dorian b2
F# Locrian - A Dorian
F# Locrian #2 - A Dorian b2

Obviously which ones you use is up to what sounds good to your ear but this is essentially how you can use the modes of any scale but a little bit deeper(think substitutions and such).

I know you can also use D super Locrian over the D7 but that's the one I can't really nicely place over the Am6 since there isn't really an A in that scale so it won't have a mode for A(could be that you just say you used D super Locrian over Am6 but that's a little weird since it has a major third in it while Am6 is a minor chord)
