What is the best way of approaching the CAGED Method. What are some good resources for beginning to learn this method.
I've been learning the CAGED System from Justin Sandercoe's website.
He begins with origin of the system and steps through each chord shape & it's notes up the length of the fretboard. He's even got nice diagrams and worksheet for reference...
He offers the information up for free but donate if you can. It's quality stuff.
I recommend checking out Fretboard Logic SE which uses the CAGED method. I found the author's approach to be straight-forward and easy to understand.
The CAGED method is based on the open string chord forms, voicing and geometry, of the C, A, G, E, and D chords. So the first step is to learn open string chord forms and learn where the root and other notes are within the chords. Then, learn movable chord versions of each. Once you can play these and know where the root is you learn to connect them. There are overlaps among the set of chords so for example you can play A chords in all voicings starting with open A (x, 0, 2, 2, 2, 0) and moving up the neck to the 12 fret and beyond. This mobility is one of the great uses of CAGED and it is related to the geometry of the chord in standard tuning, not style. Each of these 5 chord forms has a mode that it fits into, making it easy to identify the major scale of the key you are in as you move.
As for a good resource? I haven't come across an actual CAGED book but I'm sure one exists. If you work through any guitar method series you will eventually be introduced to this idea. So working through Bill Levitt's books, the Mel Bay series, Christensen's book if you are into Jazz... These all provide a solid foundation for understanding CAGED. For me, I learned it from my first guitar teacher at some point. I just have his old notes, no book. But I had already been taught my modes and chords so all it took was a single diagram showing how they are connected. Everything falls into place after that.
