Modes:
What's a mode? No it's not that green fuzzy stuff that grows on old cheese in 
the refrigerator. A mode is...well, it's kind of tough to explain I suppose. 
But let's try to work through it together and see if we can discover for 
ourselves what modes are.

Let's start with a C major scale 
C-D-E-F-G-A-B-C

2 Octaves in TAB form:

E-------------------------------------------
B----------------------------------10-12-13-
D--------------------------9-10-12----------
G------------------9-10-12------------------
A----------8-10-12--------------------------
E--8-10-12----------------------------------

This is a C major scale in its natural mode, starting on C. This natural mode 
is called the Ionian mode. No big deal, see, you knew one mode already.
What about the other modes?

Well, what if we are playing and our progression has a C7 chord in it, (which 
has a flat 7) and we want to stress that in a melody line or solo? So instead 
of playing our normal 7 in the scale (B) we play the same scale but flat the 
seventh each time (Bb). No big deal, just the one note. So now our scale 
looks like this:

C-D-E-F-G-A-Bb-C

2 Octaves in TAB form:

E-------------------------------------------
B----------------------------------10-11-13-
D--------------------------9-10-12----------
G------------------8-10-12------------------
A----------8-10-12--------------------------
E--8-10-12----------------------------------

But wait a minute! I think I recognize those notes. Yeah, a single Bb is the
key signature for F-major/D minor. Amazing! Who would have thought that? But
I'm not playing in F major or D minor.

Hmm. My progression is still in C. Yes, I'm in C but I'm no longer in the 
Ionian mode. With the flat seventh I am now in the Mixolydian mode. I know it 
sounds like we've been transported to some alien parallel universe, but don't 
worry, it's just a way of playing.

Hey guys wait up! Apparently the band has switched to C minor on me. Well, I 
know my C minor scale:

C-D-Eb-F-G-Ab-Bb-C

E-------------------------------------------
B----------------------------------9-11-13--
D--------------------------8-10-12----------
G------------------8-10-12------------------
A----------8-10-11--------------------------
E--8-10-11----------------------------------

Well, once again I have changed modes. What we familiarly call the minor scale 
is also the C Aeolian mode. While the Mixolydian has a flat 7, the Aeolian has
a flat 3, a flat 6, and a flat 7. Notice also that these notes are the same as 
an Eb major scale.

OK, Now the guys are really getting on my nerves. We just changed to a 
progression that demands a Cm6 flavor. Hmmm. First, what's a Cm6? Well, it's a 
Cm (C-Eb-G) with a major 6th added on (A).

Shoot, I can't play the scales I've been playing if I want to stress the Cm6 
sound. I either have to flat the 3 of the Mixolydian, or sharp the 6 in the C 
Aeolian. OK let's try it. The new scale is:

C-D-Eb-F-G-A-Bb-C

E-------------------------------------------
B----------------------------------10-11-13-
D--------------------------8-10-12----------
G------------------8-10-12------------------
A----------8-10-12--------------------------

OK...Now we are all experts on modes and can break further out of our timid 
selves and conquer the musical world.  (Maybe later)

Any questions, comments, additions?
