Part 3/9:
Root-based D minor pentatonic: The foundational scale rooted on D.
F major pentatonic (a minor pentatonic based on the fifth): Played on A, an important position giving a minor 9 sound.
E minor pentatonic (based on the second scale degree): Produces a minor 6/9 sound, adding upper extension color.
He demonstrates how each pentatonic scale adds different "tensions" or upper extensions—like the 9th, 11th, and 13th—that enrich harmonic color and emotional expressiveness.
Progression of Tensions
The D minor pentatonic has the least tension with only the 11th.
The A minor pentatonic adds the 9th, creating a minor 9 sound.
The E minor pentatonic introduces the 11th, 9th, and 13th, offering the most complex "colorful" sound.
