This guide maps out all of the Greek or Church modes for you.All the diagrams include the intervals within the scales rather than just dots to help you understand what you are playing, not just tell you where you need to put your fingers.For each mode, Ionian, Dorian, Phrygian, Lydian, Mixolydian, Aeolian and Locrian, you get the mode as a 4 note per string 3 octave scale and the 7, 3 note per string patterns that allow you to play in any mode in any key, anywhere on the guitar neck.
