Casaerwin ___ ( continuing ), Knowing that the 'Major Modes, are,... 'Lydian, Ionian, Mixolydian... and the 'minor Modes, are ... 'Dorian, Aeolian, Phrygian... and that pesky, 'Locrian, is minor, with a flatted 5th, helps you navigate around the fret board. Similarly, any 'Scale or, 'Mode, that has a flatted 3rd, makes it a 'minor Mode. There are, 'Parallel Modes, and 'Modes in Series. The 'trick, my mind uses, is to think, no matter where, or what, Fret-Note' I am on... I can think in 'Alphabetical Key of ( i.e.) Mixolydian ( with a flat / dominant 7th ) and be in that Key. This does not work for everyone. This just how my, newbie (70+ ) mind works.
