BCAGED octaves (BEADGC : 6-string bass standard tuning)
C major scale (3 notes per string) : General

In BLOGoZON No.269 the box shapes for the C major scale were presented using the BCAGED octaves methodology - this is the CAGED octaves guitar system adapted and improved for 6-string bass.

In this BLOGoZON we look at the C major scale, again, but with 3nps shapes and join them all together to form one long BCAGED octaves chain.

The diagram that follows shows all seven of the BCAGED octaves shapes for use with
the three notes per string patterns for a 6-string bass tuned to BEADGC :-

As always a more long term solution to fretboard navigation is to see scales 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 major scale are detailed below in the BCAGED octaves manner:-

The tables and tabbed panels below detail all seven box shapes for the
C major scale
in the BCAGED octaves style.

Once the individual box shapes have been assimilated all seven shapes should be linked together and played in one continuous exercise (with the first shape - 6B4C1 - being repeated at the 12th fret).

The video shown to the right demonstrates the BCAGED octaves chain-linked sequence for the C major scale 3nps box shapes.
