I'll politely disagree. Other than a black key scale having no semitones (critical to the concept of anhemitonic (nonhemitonic, no half steps) pentatonics it's way of looking at its usefulness ends there. The five pentatonic modes are positively modal.
The second semitone following a note (7th) in Lydian and Ionian is the tonic so there is no associated pentatonic mode.
Pentatonic Mode 1 is formed by dropping the semitones from Phrygian. Often thought of as blues minor.
Pentatonic Mode 2 is formed by dropping the semitones from Mixolydian. A major sounding scale. Popular in country and pop.
Pentatonic Mode 3 is formed by dropping the semitones from Aeolian.
Pentatonic Mode 4 is formed by dropping the semitones from Locrian. Not a popular pentatonic mode because of its tri-tone sans dominant 5th.
Pentatonic Mode 5 is formed by dropping the semitones from Dorian. It yields a scale that is neither Major or minor and is often used in music thought of as modal in old-time music.
Modes 1, 2 & 5 are the most popular of the pentatonic modes, at least in the US.
And yeah, the Locrian tri-tone (the devil's interval) was a no-no back then.
I just noodled around with that Super Locrian. Adding the Major 3rd makes the absence of the dominant 5th less jarring and a somewhat exotic sounding scale. Kind of cool. Thanks for mentioning it.
Actually pentatonic is completely distinct from modes. The black keys are a pentatonic scale and orthogonal to the modes.
In the Middle Ages you could be executed for playing in Locrian, B to b on the white keys.
Robert Fripp showed me Super Locrian, B C D E♭ F G A B
