ExampleS permutations of four-note units
In the first of two lines derived from CAGED shape #4, this one stays mainly in A Dorian (1-2- 4-5-6- but with the occasional shift from a C note (minor 3rd) to a C# note (major) in bar 26; firstly via a microtonal ‘curl’, and then with a more full-blooded bend on the fifth string for the penultimate note.
Apart from the C note in beat 3 of bar 26, this shape #4 line is pure A Mixolydian, mainly based around an A7 arpeggio, A major Pentatonic scale and a Gmaj7 arpeggios: all of which can be found within the scale.
The bulk of this line is taken from CAGED shape#5 of A Mixolydian
EJ(again refer to Diagram 1 and play 1-2-3-4-5-6- in the fifth neck diagram). The only deviation is the penultimate note which is a minor 3rd (C ), and even that’s bent up slightly towards a C#.
This and the remaining examples shift between positions. We start in shape #2 and finish in shape #1. Look out for shifts between C and C#
Eb notes (minor 3rds to major), and the inclusion of ( in this case, acting as a
Eb- chromatic bridging note between E (5th) and C# (E- D and C# – even though it may be disguised slightly with the inclusion of other surrounding notes).
