What order do the modes (Aeolian, Ionian, Phrygian, Lydian, Mixolydian, Locrian, Dorian) go on the fretboard. Like so you can switch between them without going out of key.

You appear very confused. Read this:

Modes of the Major Scale

First of all, a mode is a scale derived from a different scale. The basis behind deriving modes is making a note that is not the tonic of your new root note! There are 7 basic modes derived from the major scale. If you don't know the major scale, learn it ASAP. The intervals are W W H W W W H.

Anyways, since there are 7 notes in the major scale, you can have 7 different root notes (or starting points) and still be in the same key. For the purpose of this lesson I'll be using the key of C, because it has no flats and no sharps, and is one of the most common keys.
Here's a diagram to help with the concept:

Key of Cmaj: C D E F G A B C D E F G A B C D E F?
[b]C[/b] Ionian     [b]C[/b] D E F G A B [b]C[/b]
[b]D[/b] Dorian       [b]D[/b] E F G A B C [b]D[/b]
[b]E[/b] Phrygian       [b]E[/b] F G A B C D [b]E[/b]
[b]F[/b] Lydian           [b]F[/b] G A B C D E [b]F[/b]
[b]G[/b] Mixolydian         [b]G[/b] A B C D E F [b]G[/b]
[b]A[/b] Aeolian              [b]A[/b] B C D E F G [b]A[/b]
[b]B[/b] Locrian                [b]B[/b] C D E F G A [b]B[/b]
[b]Bold[/b] notes are root notes of each scale.


First of all, start thinking of notes as scale degrees:

  Note: C D E F G A B C
Degree: 1 2 3 4 5 6 7 1


The names of the modes, in order, are Ionian, Dorian, Phrygian, Lydian, Mixolydian, Aeolian, and Locrian, and they start on their respective scale degrees.

Starting on the first degree, you get 1 2 3 4 5 6 7 1, which is Ionian. Also the major scale.

Starting on the second degree, your notes are D E F G A B C D. This is the Dorian mode. Its formula is 1 2 b3 4 5 6 b7 1. Here's why:


 Degrees: 1 2 3  4 5 6 7  1
 D scale: D E F# G A B C# D

D Dorian: D E F  G A B C  D
 Degrees: 1 2 b3 4 5 6 b7 1


You should be able to see how the F# was flatted down to F natural and C# down to C natural. That is how each mode's formula is found.

The third mode is Phrygian, its formula is 1 b2 b3 4 5 b6 b7 1. In the key of C, the notes would be E F G A B C D E = E Phrygian.

The fourth is Lydian. Formula is 1 2 3 #4 5 6 7 1.

5th is Mixolydian, 1 2 3 4 5 6 b7 1.

6th is Aeolian, or the natural minor scale. 1 2 b3 4 5 b6 b7 1.

7th is Locrian, which is a half diminished scale. 1 b2 b3 4 b5 b6 b7 1.

These formulas are intervals in relation to the major scale. The major scale is used as a reference for just about everything, and modes are no exception.

Therefore, the 7 modes in the key of C are:
C Ionian
D Dorian
E Phrygian
F Lydian
G Mixolydian
A Aeolian
B Locrian
#3
Let us start in the friendly key of C major (8th fret), the order is as follows.

C Major
D Dorian
E Phrygian
F Lydian
G Mixolydian
A Minor
B Locrian

And it just shifts up and down the fretboard, but ALWAYS the same order.

The way I learnt was to learn each one individually and then piece them together, I think most people do it like that, but what worked for me might not work for someone else.

Whatever way you learn it though, thems the rules!

Thanks, I know all the modes I just needed the order they fit in. that helped alot
