This may prove helpfull. There is much work involved. With honest dedication, this should not take long to be functional.
Modes

I have a different, but functional way at looking, or more importantly, playing and hearing modes.

First, there are only five basic chord forms on the guitar. Modes are quickly found by understanding intervals and intervals within those chord forms and thoroughly knowing how to play major scales. Also, two ways to alter them, simply. (works great in terms of pentatonic.)

Second, to make this system work, thorough knowledge of playing major scales is paramount.
Berklee series shows all 7 forms of major scales for the guitar. Quickly speaking, to alter any major scale is to lower the third (b3) or raise the fifth (#5). A very fast way to learn harmonic and melodic minors. Both versions of pentatonic, major and minor. (5 forms) (really the same thing, just point of view.)

Third, the trick. I don't much care about whether it's per key, per chord or cycle, I am after the
sound.

Play a major scale from:

Ionian - Root (for G play Gmaj scale) I

Dorian - b7 or whole step down from root (for G play Fmaj scale) ii

Phyrgian -m6 above the root (M3 below the root) (for G play Ebmaj scale) iii

Lydian -5th above the root (for G play Dmaj scale) IV

Mixolydian - 4th above the root (for G play Cmaj scale) V

Aeolian - m3 above the root (M6 below the root) (for G play Bbmaj scale) vi

Locrian -1/2 step above the root (for G play Abmaj scale) vii


This system will expand everyone's musical ability, regardless of genre, blues, country, rock, jazz or pop. There will be a certain amount of practicing. Jamming helps. Using this system is great for creating new and/or personal licks. If one is a pentatonic player, it's a great way to visualize the guitar and expand your playing. This system is so ingrained into my psyche, I know longer think or even know I am using it.
