Thanks, Malcom, Ironically, I have never thought of modes as being 'major' or 'minor'... I like that concept - will keep it in mind when choosing one
Just a little mode stuff.... Parallel modes where the key stays the same and the notes change. I like Parallel much more than Relative modes where the key changes and the notes stay the same. Both get you to the same place, your choice.
The Major Modes -- natural 3's
R-2-3-4-5-6-7 Ionian home base for major modes. AKA the Major Scale.
R-2-3-#4-5-6-7 Lydian change one note.
R-2-3-4-5-6-b7 Mixolydian change one note.
The minor modes -- b3-b6-b7
R-2-b3-4-5-b6-b7 Aeolian home bass for the minor modes. AKA Natural minor scale.
R-2-b3-4-5-6-b7 Dorian yes sharp the b6 back to a natural 6. Change one note.
R-b2-b3-4-5-b6-b7 Phrygian and here add the b2. Change one note.
R-b2-b3-4-b5-b6-b7 Locrian and here add a b2 and a b5. Well here change two.
- Ionian - happy, and up beat. IMO If the guys are not laying down a vamp you might as well stay tonal and use the major scale.
- Lydian - about the same as Ionian and I seldom use it for that reason. Now add a b7 with that #4 making it Lydian Dominant and it comes alive. Kinda half way between Ionian and Mixolydian.
- Mixolydian - Latin and of course used over the dominant seven chord quite a lot. I do not agree with changing modes over each chord. Why? Each mode has a mood if you change moods three times in a song you just confuse the issue. Pick a mood and use the mode that gives that mood.
- Aeolian - home base for the minor modes. I hear minor. Seldom use it as Dorian speaks to me more so than Aeolian. The guys will normally be laying down a progression not a vamp, so just use the Natural Minor scale and staying tonal works out best most of the time.
- Dorian - an attractive minor jazz sound. If I go minor Dorian is my mode of choice.
- Phrygian - Middle Eastern. Gyspy.
- Locrian - dark and tense. Best used over a one chord vamp (m7b5 chord).
Now all that said; as a bassists modes are for when you want to make your solo or bass line melodic. Pounding out notes of the chord, walking to the next chord, and maintaining the groove is our first job. The guitar guys get off on modes, let them do the modes until they start giving you some lead breaks. That's the time to reach in for your modal stuff. IMO.
That is how I see it. And that will get you just about ankle deep into this mode stuff. Modal harmony will take you to your knees.

Good luck.
