AGEDC4BASS : 4-string bass in standard EADG tuning
A minor arpeggio (3 notes per string) : General

In BLOGoZON No.37 the box shapes for the A minor arpeggio were presented using the AGEDC4BASS methodology - this is the CAGED guitar system adapted and improved for minor scales and arpeggios on 4-string bass guitar.

In this BLOGoZON we look at the A minor scale, again, but with 3nps shapes and join them all together to form one long AGEDC4BASS chain.

The diagram that follows shows all seven of the AGEDC4BASS shapes for use with the three notes per string patterns for 4-string bass guitar tuned to EADG :-

The conjoined AGEDC4BASS sequence is shown for A natural in the diagram that follows:-

The diagrams that follow show all of the A minor arpeggio notes plotted over the 4-string bass's fretboard in both the Guitar Pro and AGEDC4BASS styles:-

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 A minor arpeggio are detailed below in the AGEDC4BASS and GuitarPro5 manner:-

The tables and tabbed panels below detail all five box shapes for the A minor arpeggio in the AGEDC4BASS 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 - 3Am1Gm - being repeated at the 12th fret).

The video shown to the right demonstrates the AGEDC4BASS chain-linked sequence for the A minor arpeggio (3nps) box shapes.
