modes should be thought of as keys. a scale is a source
from which to extract chords for progressions.
a mode is a scale so for it to be of any use song wise
you must extract the chords from it.
most guitar players are taught the modes in relation to the
major scale which is the source of the confusion.
Modes are independant keys in their own right with
their own set of scale tone chords and own distinct flavour.

Another confusing way modes are taught is that scale to
chord relationship. e.g In c major , a progression that goes
c , am , F , G . would mean c Ionian for the c major chord ,
a aelion for the am chord , f lydian for the f major chord
and g mixolydian for the g major chord.

This would have to be the worst way to look at modes
if your objective is to highlight the distinct flavour
of the modes.
The problem with this approach is that we hear harmony
in the basic sense of tension and release.
In the key of c major `C' is considered to be tonal centre
or `home or tonic' or whatever you want to call it.
Earwise this chord is considered to be the most resolved or
home chord.
whatever chord is played in the key of c now will be to
some degree be tense or resolved depending on its relationship to the
key centre or c chord.
This is a fact and the fundamental principle behind harmony.

To tie this back to modes it means that if you were to play the f lydian scale over the f major chord in the previous progression you would not hear the true flavour of the lydian mode.
your ear would simply being hearing notes being played against the fourth chord of c major key waiting for the tension to be released with a return to the c or `tonic' chord.

To have a true representation of the f lydian mode in a song f chord would have to be the tonic or home chord e.g the progression F / G / F / G.

In other words it is the chord progression that dictates wether the true sound of a mode is heard or not.

Modes when thought of as keys are actually very simple. Most modal chordal progressions in rock usually consist of two ot three chords.
One of these chords will be the definitive chord of that mode. This is a little harder to explain so I wont bother at the moment.

Songs do not stay on one chord all the time. Any notes that you are playing at a particular point have that particular sound ,colour or characteristic
because of their relationship to the underlying chord , and in turn that chord has it`s particular sound or tension because of it`s relationship to the`tonic' or `home' chord.
You can begin to see how important key centres are when it comes to how notes and chords sound.

The bottom line modes are just keys. If you extract the scale tone chords from the key and base your progressions on it you will end up with the true
harmonic colour of that mode.
a lot of rock and metal songs use progressions based on modal keys but still use simple pentatonic scales over them . a lot of them would not even realise the progression is extracted from a
a modal scale. It can be that simple if you want.
Sure it can get a lot more involved but for most guitarists they just want a basic understanding of what the hell a mode actually is or what it does.

Playing in major or minor keys all the time can get tiresome to the ear.
Modes can bring a fresh new sonic approach to a solo instead of the same old pentatonic
scale material everytime.

I hope this has`nt caused anyone more confusion about this subject and hope it has helped
somebody clear up some misconceptions about modes.
