A minor arpeggio and A minor arpeggio box shapes

In BLOGoZON No.36 the box shapes for the A NATURAL MINOR SCALE were presented using the AGEDC4BASS methodology - this is the CAGED guitar system adapted and improved for bass guitar.

In this weeks BLOGoZON the box shapes for the A natural minor scale are revisited but this time the undelying 3-note chord/arpeggio is presented i.e. A minor.

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

AGEDC4BASS A natural

GuitarPro6 A natural octaves

The diagrams that follow show all of the A natural minor scale 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 natural minor scale are detailed below in the AGEDC4BASS and GuitarPro5 manner:-

AGEDC4BASS A minor scale intervals

All scales and modes have an underlying triad - 3 note chord - that defines their basic tonality.

In the case of the A natural minor scale this is the A minor arpeggio - hence the notes for a

A minor arpeggio are presented in both the Guitar Pro and AGEDC4BASS styles:-

GuitarPro6 A minor arpeggio notes

AGEDC4BASS A minor arpeggio notes

Similarly the intervals forming an A minor arpeggio are shown next:-

AGEDC4BASS A minor arpeggio intervals

The tables and tabbed panels below detail all five box shapes for the A natural minor scale and the
A minor arpeggio in the AGEDC4BASS style.
