Lesson: Walk that bass (G blues) first chorus


This week a chorus of walking bass under a G blues. This is playable with a pick as well as fingerstyle.

The following chord changes are used as the basis:

|| G 7 | C 7| G7 | % | C7 | % | G7 | E7 | Am7 | D7 | G7 E7 | Am7 D7 ||

The chords used here are so called drop two chords, consisting of the third and the seventh of each chord. They represent the complete functionality of the chord: an approach that will be part of another lesson soon.

Here we go
G bLues chorus 1 1-4

In bar one the bass follows the major triad tones and chromatically walks back to land on the C root in the second bar. A chromatic approached is used to walk from the E note (third of C chord) via F and F# back to G. In bar four a chord sequence is applied on the bass notes. G7, Am, Bb dim,  B min. 

G bLues chorus 1 5-8

Bar 5 uses the C 7 drop two chord in position VIII, the bass consists of the chord tones. Bar 6 is a chord sequence C7, Bb6, Am7, G#7. The G#7 or Ab7 is the chromatic option that comes from replacing a  D7 dominant chord resolving to G with its so called tri-tone substitution. In bar the bass line chromatically ascends to E on the last beat. Similarly a chromatic descending last beat note is found in bar 8 which resolves to the Am7

G bLues chorus 1 9-12

In bar 9 the Eb note on beat four descends chromatically to D7, just like in bar 9 the G# (Ab) descends to G. Bar 11 and 12 are a so called turn around. Notice how the tritones are used for chromatic purposes in bar 11 and 12 on the fourth beat.
