Is the caged system pentatonic?
This pentatonic scale shape fits right over your E shape C major bar chord. This is a handy one when you're switching between rhythm and lead guitar. The final shape sits on top of our D shape C major chord. Just like almost everything else on the guitar, the CAGED system can be moved around freely.
What is a caged system?
A system for playing notes up and down the guitar fretboard by memorizing fingering positions for these specific chords: C, A, G, E, and D. You can play any chord higher up on the fretboard by playing the next shape in the sequence.
How do you master a caged system?
The trick to the CAGED system is to visualize the chord shapes without the capo. This is easily done by memorizing where the root note for each chord shape is located. The root of the E shape is the open 6th string. The open 5th string is the root of the A shape.
