There are 5 chord shapes in standard tuning that can act as a framework for all of the others. They are C-A-G-E-D. This is the ‘CAGED’ system. It can act as a ‘scaffolding’ type learning tool, which is ‘removed’, once pure knowledge is a reality (“this is C, this is C, this is C…”).
We will learn how each of the forms move up the fretboard in the order of most common usage [E & A first, then D, C, G]. E & A, D are similar; C & G are similar.
Some of the above chords can be fretted in more than one ways. So, no fingerings. The R-3-5s that you see are the chord component. We get to the task of memorizing the string address of these components. They are the base point for modifying forms to create other types of chords.
To get started, we make sure we have all of these chords in the hands. We will move parts of them, as well as fuller forms. We have options. These options build our chord catalog preferences. And, which voicings we use are based on the stylistic context of the music we are playing (blues uses mostly Dominant 7 types – and specific ones – for Major type blues).
