Here's a good graph of modes in C (men do better visually)


--C--D--E--F--G--A--B--C
-----D--E--F--G--A--B--C--D
--------E--F--G--A--B--C--D--E
-----------F--G--A--B--C--D--E--F
--------------G--A--B--C--D--E--F--G
-----------------A--B--C--D--E--F--G--A
--------------------B--C--D--E--F--G--A--B


Notice that there are 7 modes. Small roman numerals mean they sound minor. Lets explore mode ii (the dorian).

The intervals between each note are either 1 whole or
5 for (.5) for a half step. For the Dorian they are

D to E = 1
E to F = .5
F to G = 1
G to A = 1
A to B = 1
B to C = .5
C to D = 1

1.5.1.1.1.5.1

Those intervals are very different from the 1st mode IONIAN intervals of:

C to D = 1
D to E = 1
E to F =.5
F to G = 1
G to A = 1
A to B = 1
B to C = .5

1.1.5.1.1.1.5

Now you can see why modes although based off of the same scale, sound vastly different.

Here's an experiment for you.
Play the IONIAN mode across all six strings (all notes played in four fret range) Play it long and hard and hear it.

Now put the guitar down for about 20 minutes, come back and play only the dorian mode. You will hear a major difference.
