Today we will look at a John Mclaughlin alternate picking Jazz/Fusion improvisation cadence employing the altered dominant chord! Please watch the video below and then try it out yourself.
As you will see 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.
