Well, the modes start on different steps of the major scale. The Ionian mode starts on the first scale step, the Dorian mode on the second scale step, the Phrygian mode on the 3rd step, Lydian mode on the 4th step and Mixolydian mode on the 5th step, etc.
If you analyze each mode, you'll see that the Ionian scale is the major scale; the Dorian scale is a minor scale; the Phrygian mode is a minor scale; the Lydian mode is a major scale; the Mixolydian mode is a major scale; the Aeolian mode is a minor scale, and the Locrian mode is a diminished scale.
in eyes of the world though, i tend to just use the major scale in every chord progression. it sounds ok during the G-C-G-C-D thing, but when i use it during B at the jam, it sounds off, but i can't get it to sound right.
It might not sound right during the chorus (the G-C-G-C-D part) if you are playing the G major scale (or Ionian mode as they are the same thing), then the C major scale and then the D major scale. Since that part of the song is in the key of G, the C major scale and the D major scale will introduce dissonant notes that can sound incorrect.
What you want to be doing is playing in the key of G, using the G Ionian mode, C Lydian mode and D Mixolydian mode under the respective chords.
but yeah, i understand how to use modes and all the fingering, it's just confusing to find out that some songs use more than one mode.
The "jam" is properly called a "vamp" when it just goes back and forth between two chords (say, Emaj7 and Bmin7). Let's just stick with that for now.
What's happening here is that the song is shifting keys. This happens in each verse of "Eyes of the World" in which one line is in E major and then there's a sort of punctuation in A major between the lines Jerry sings. Look at the chords- do you see where that happens?
The Emaj7 chord is the I chord of the key of E (it can also be the IV chord in the key of B). So you can use the E major scale (Ionian mode) under the Emaj7 chord and sound good. You could tweak things a bit, think of it as the IV of B and play the E Lydian mode under Emaj7. That might sound OK.
Then the song shifts for a couple of bars to Bmin7 and A major. Ba-dom ba-dom, ba-dom ba-dom. Over this you want probably to play in the key of A, so over the Bmin7 you could play B Dorian and then A major (A Ionian).
Then for the choruses the song shifts to the key of G, which we've already covered.
So there are at least two ways to organize how you think about the song, which in turn determines what you play. First is the concept of "tonal center." A song is considered to be in a key, but the key can change. Different sections of the song can be in different keys ("Eyes" being a good example of this). So, if you asked me what key "Eyes" is in, I'd say "E major." But the tonal center of the verses changes from E to A, and the choruses are in G! So when I think of key I think of "tonal centers-" which is "what key is this bar or set of bars in?" Most songs begin and end in the same tonal center.
The other way is through associating modes with chords. Keys have sets of chords (capitalized are major, lower case are minor with the exception of vii): I, ii, iii, IV, V, vi, vii. The vii chord is a diminished chord meaning it has a minor 3rd and a flatted 5th. Anyway: the Ionian mode goes with the I chord, the Dorian mode goes with the ii chord, the Phyrygian mode goes with the iii chord, the Lydian mode with the IV, the Myxolydian mode with the V, the Aeolian mode with the vi and the Locrian mode with the vii. So when you see a minor chord you need do decide what its function is: is it the ii, iii or vi? That will tell you what mode to play. If you see a dominant chord (D7) you play the Mixolydian mode. A major triad could be the I, IV or V in any given key, so you have to do some analysis in order to pick your mode. With practice this becomes almost instantaneous (if you're like Phil, you know what it is before it happens... and then you play something unexpected).
I think I got those in the right order: I Don't Play Like My Aunt Lucy: Ionian, Dorian, Phrygian, Lydian, Mixolydian, Aeolian, Locrian.
Geez, does that make any sense to a guy playing music less than a year? This is pretty abstract stuff! Tell me if I am confusing you. I'm not a great teacher and I tend to pull in too many things too quickly.
