This issue demonstrates the ideal notes to create bass-lines over DOMINANT SEVENTH chords i.e. dom7.

The easiest example of the dom7 is rooted on C natural, hence the C natural version of the CAGED4BASS octave sequence is shown in the diagram that follows:-

The diagram that follows shows all of the Cdom7 arpeggio notes plotted over the entire 4-string bass guitar's fretboard in the CAGED4BASS style:-

CAGED4BASS Cdom7 arpeggio note names

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 Cdom7 arpeggio are detailed below in the CAGED4BASS manner:-
