Using The Modes Over Chords.
Ionian – It is just the name for the major scale. It has no alterations made to it. This mode can be played over Major chords, Maj7, Maj6.

Dorian- Dorian mode has a flattened third and seventh (b3 and b7) making it ideal for m7 chords. You can also use Dorian mode for m6 chords. Dorian mode is often used in jazz styles.

Phrygian- Phrygian mode has a lowered second, third, sixth, and seventh. Phrygian has a Spanish feel to it so you can Play it over Spanish progressions or heavy metal/rock riffs with a b2.

Lydian- Lydian mode's only alteration is a raised fourth (#4) making it very close to the major scale. The #4 makes it a good chord to use for Maj7#11 chords, but can also be used over maj7 chords.

Mixolydian- The only alteration in Mixolydian mode is the lowered seventh (b7). This makes it perfect for dominant 7th chords. This mode can be used in blues, jazz or even country.

Aeolian- Aeolian mode, a.k.a. the minor scale has a b3, b6 and b7. (All minor scales have a b3). Aeolian mode works over minor chords, and can be used as a substitute for Dorian mode, by using it over m7 chords.

Locrian- Locrian mode has a b2, b3, b5, b6 and b7. Locrian mode is very dark sounding. It fits a m7b5 chord perfectly.
