Here's the backing track for the tutorial. It's a C pedal which you can use to play any set of quartal chords to outline a particular mode as I did in my examples video.
Try making C dorian by starting on the II chord at the note C,
C Phrygian by starting on the III chord at the note C,
C Lydian by starting on the IV chord at the note C,
C Mixolydian by starting on the V chord at the note C,
C Aeolian by starting on the VI chord at the note C,
C Locrian by starting on the VII chord at the note C.
Enjoy playing quartal grooves - next time we'll use these in the context of a chord progression!
See you there.
