I'm looking for a clear explanation of the relationship of modes (Ionian, etc) to scales and chords. I know that the Ionian is the same as the major scale. I know that the Mj7th, Mi 7th and Dom. 7th chords are derived from the I, ii and V modes respectively. And I know that for there are seven modes which share the same key as their major scale (e.g. all modes of D Mj share that key, with F# and C#).

So I have this general understanding but I don't really understand the complete relationship of the modes to chords and scales, and I'm not sure I understand how one uses the modes.

I know this is a bit convoluted but I'm guessing that some of you shared a similar confusion at some point in time and can help me out here. None of the many books I have explain it very clearly. While they discuss the modes and some even lay out all of the modes for every note, none really explain the purpose of the modes.

I have so many books at this point, including The Jazz Theory Book by Levine. I'll take a look at it.
That one is very comprehensive and easy to read. Modes are covered in the first several chapters.

Ok, I think I might see - uh something. Does it have to do with, like in the example here, the fact that you might not want to go to the A scale because then you'd have a G#, whereas in the A Mixo mode/scale, the G is not sharp, as well as in the A7 chord, the 7th is lowered so no G# as well. Basically, A Mixo is more consonant because the share the same key?

Feel free to talk down to me - some of this stuff should be more obvious, but it's making me feel mighty dense at times. :? :!:
See page 16 of The Jazz Theory Book. It's all right there.
