Example6 Combined quartal voicings in a bluesy R&B style
EThis light blues progression in the style of The Crusaders shows Mixolydian and Dorian shapes combined. When you have looked at the layers for a while you Eb9=Bbm7 Bb7= will connect them together in a static II-V layer – or Fm7. Also notice the added chromatic shapes in Bar 4, beat 2 & e (F#-B-E top), and Bar
Ab-Db-Gb- 10, beat 4e ( B top) added for smooth connection. This is in the style of guitar wiz Phil Upchurch, so a clean jazz guitar tone is required.
