See how the patterns are exactly the same but the Root note and the Name have changed?

But see the contrasting thought on the last page when a name is tied to ONE pattern.

While it's easy to learn the patterns and call them a name...sometimes it takes people years or decades even to realize the name has nothing to do with the pattern...it's the Root note that will give it it's name. And regardless of the pattern...it's the Intervals from the Root that corespond to the name.

The most important thing you can learn about modes is, learn the chords they belong to.

So, look down the right side of each modes chart and learn what chords are built from what modes.

For instance, ANY time you see a Dominant 7th, 9th, 11th, 13th chord...playing a Mixolydian from that chords Root is a dead ringer.

If you see a maj7 chord, from the chords Root - Ionian, or Lydian are your choices, sometimes they are even interchangable and can be used together...because they imply that same maj7 chord.

If you see a m7 chord...try Dorian, Phrygian, Aeolian...a m7 chord can be built from each of them.

BUT...you have to also understand Keys, and how the chords are built from a Tonic in the Diatonic system...

Now go read that mode doc (http://lessons.mikedodge.com/lessons/MusicTheory/Diatonic/DiatonicTOC.htm) and read it to learn what sound, what chord, a mode implies.
