My own breakthrough with teaching the CAGED system came when I realised that although at first glance the pattern it makes looks quite complex, it is actually made up of just 7 individual octave patterns.

And these seven patterns can themselves be divided into two fundamental patterns. These I call the forward diagonal and the backward diagonal.

The basic shape of the forward diagonal is what I call a two by two. 2 frets up and 2 strings across and starting on either of the bottom two strings this holds true. But when you bring the 3rd string into play, because of the tuning anomaly, you have to stretch the forward diagonals.

So, off the fourth string we get a stretched forward diagonal, instead of a 2 x 2 we get a 3 by 2 and the same holds true for the forward diagonal off the 3rd string.

The basic backward diagonal octave pattern is a -3 x 3. You go back three frets and up 3 strings. But here again you need to accommodate the 3rd string tuning anomaly. This time by shrinking the shape as you move up from the bottom string to the 5th string lower key note. And this shrunk shape holds good for the backward diagonal octave shape off the 4th string as well.

So to recap the CAGED system can be broken down into two fundamental shapes - forward diagonals and backward diagonals.

For example the C shape is made of a shrunk backward diagonal, the A shape a normal forward diagonal, the G shape has both a normal backward diagonal and a stretched forward one...the E shape a normal forward one combined with a shrunk backward one and the D shape is just a stretched forward diagonal.

From this way of looking at the CAGED system I developed what I call the Sandwich Drills. These can be used with any type of scale, mode or arpeggio, but it's best to start with the Major scale to get your bearings.

This is a way to condition the fingers and ears to be able to map out a Major scale anywhere on the fret board using any part of the CAGED system. The end result is that you can locate at least one discrete octave of the scale in any key, going in any direction, in any area of the fret board.

Here's a quick view of how this is applied. Using my fiendishly sophisticated random note and fret number generating machine, I first pick a note - any note then I pick a fret number between 1 and 12

So I have to find an X major scale in the area of fret Y

I use the CAGED system for the note selected to home in on the octave patterns in the region of the selected fret number the conditioning from my sandwich drills then kicks in and I play the pattern for that part of the CAGED system.
So, on its own, the CAGED system helps you locate any NOTE on the fret board, but add in the sandwich drills and you can extend this ability to being able to locate scales, modes and arpeggios.
