Mapping the Guitar Neck

There are notes all over the neck of the guitar. Unlike the piano, the notes are not laid out in an (reasonably easy to manage) orderly fashion.

Here is where you can find all the notes on the neck of the guitar from open position to the 12th fret.

So how can this information be helpful to us guitarists? With a little understanding of chord construction, you can find new ways to play the same chords you already know. 

Try it out...
Here are the notes in some of our familiar chords. Try finding new places to play them on the neck of the guitar. See if you can come up with at least two new ways to play the following chords:

G = G, B, D
C = C, E, G
D = D, F#, A
Em = E, G, B
Am = A, C, E

The notes can be in any order you want on any combination of strings. Neck mapping is sort of a word search but with musical results.
