This cadence employs the Altered scale. It is a 2 [minor 7 flat 5] going to 5 [ “Altered Dominant”] 1 [major 7th]. This being Dm7 flat 5 G7 altered resolving to C major7.
I also employ a flat 5 substitution on the Dm7 flat 5. All of this resolves though and slips nicely into the altered dominant 5 chord. I also use pentatonics within the altered scale for rhythmic flow. Please look at the TAB/MUSIC below and play through it yourself to see and feel how it all “Naturally” unfolds. I employ alternate picking the same as John Mclaughlin.
John Mclaughlin Jazz Improvisation Lick:
VARIATION With an A flat Pentatonic shape replacing A flat minor/Major Arpeggio for the flat 5 substitution.
