Watch the Dawn of Lee: 2 online guitar lesson by Carl Verheyen from S.W.A.T. Sessions: Jazz Rock
Here we discuss the boutique mode of the harmonic minor as it applies to a dominant chord a 5th above (or a 4th below). In other words, I use F harmonic minor when I play on the C7 chord in bars 21, 21, 24 and 26. It’s the gypsy jazz approved scale that fits perfectly here and in many other progressions where a V7 chord resolves to a minor chord.
