Most everyone knows the basic open chords (the ones you play
in the first 4 frets of the neck).  But a lot of folks don't
realize that those same chord forms are all moveable!  And
you can get some really nice sounding chords just by moving
up the neck.
What I will post here is some "C" chord shapes and where the
root is, then a little explaination as to how to utilize the
shapes in different positions.

The open "C" chord is this: e -0 (e)
                            b -1 (c)
                            g -0 (g)
                            d -2 (d)
                            a -3 (c)
                            E -x

Now, to make that a 7th chord: e -0 (e)
                               b -1 (c)
                               g -3 (Bb)
                               d -2 (e)
                               a -3 (c)
                               E -x

And the last one I'll bring up is the 9th: e -0 (or 3)e (g)
                                           b -3 (d)
                                           g -0 (g)
                                           d -2 (e)
                                           a -3 (c)
                                           E -x
You'll notice that the root is on the "A" string and the "B"
string, but we'll focus on the "A" string root.

If you slide the entire chord shape up 2 frets, and play the exact
same forms, you are now playing a "D4", "D7" and "D4+9".  That last
one is one of my favorite chords.

If you slide the "C7" form up so the root ("A" string) is on
the 7th fret, you are now playing an "E7" chord, and so on
up the neck.

You can apply this to every chord, as long as you know where the root
is.  My personal favorites are what I call "Middle chords",
where I only play the middle 3/4 strings.  The shapes I use for those
chords are "D", "F", and "A".

Play around all you can by moving your open chords up and
down the neck.  I guarantee that some of these chords will
spark some
