Mate, a mode is simply a permutation of the notes in a mother scale
The most important thing you must know and understand, is that everything regarding modes is based on three things:
1) Learning to hear the differences between them - this involves ear training and knowing what scale degree is characteristic for each mode
2) Knowing where those notes are on the neck
3) Knowing how to combine notes which chords - that all goes down to understanding what is the actual effect of playing a certain note/ group of notes against a particular chord
You must know that the modes can be classified like this:
Major (the contain a major 3rd) - Ionian, Lydian, Mixolydian
Minor (the contain a minor third) - Dorian, Phrygian, Aeolian, Locrian
If we look at the major scale - the Ionian mode, as it is also called, we will notice the following structure:
1 2 3 4 5 6 7 -> these are the scale degrees of the Ionian/ Natural major scale
From this point we tweak this formula to obtain the other modes wink.gif
Lydian -> 1 2 3 #4 5 6 7
Mixolydian -> 1 2 3 4 5 6 b7
Dorian -> 1 2 b3 4 5 6 b7
Phrigyan -> 1 b2 b3 4 5 b6 b7
Aeolian -> 1 2 b3 4 5 b6 b7
Locrian -> 1 b2 b3 4 b5 b6 b7
By 'b' (flat) we understand that we raise that degree to which the 'b' is attached and by '#' we understand that we raise that degree to which the '#' is attached.
Are we good so far?
