CAGED4BASS C pentatonic major scale box shapes

In BLOGoZON No.38 the box shapes for the C pentatonic major scale were presented using the CAGED4BASS methodology - this is the CAGED guitar system adapted and improved for bass guitar.
In this BLOGoZON we take a closer look at the C pentatonic major scale box shapes and join them all together to form one long CAGED4BASS chain.

As always a more long term solution to fretboard navigation is to see scales/arpeggios as INTERVAL shapes rather than note names - as these are universal to all scales, arpeggios and chords rather than specific to one particular root note - with this in mind the intervals for the C pentatonic major scale are detailed below in the CAGED4BASS manner:-

The tables and tabbed panels below detail all five box shapes for the C pentatoic major scale in the CAGED4BASS style.

Once the individual box shapes have been assimilated all five shapes should be linked together and played in one continuous exercise (with the first shape - 3C* - being repeated at the 12th fret).

The video shown to the right demonstrates the CAGED4BASS chain-linked sequence for the C pentatonic major scale box shapes.
