Being the "curious" person that I am (I've been called worse), I imagined how these Pentatonic "spreads" might sound as single-note arpeggios and sequences.
As it turns out, approaching the Major Pentatonic Scale from this angle produces a somewhat novel, intervallic, Kalimba-like effect.
By itself, this perspective can function as an excellent warm-up exercise, building technique as well as creating another look as to how one imagines and expresses the Major (or any other) Pentatonic Scale.
Every other note of the Major Pentatonic is skipped, ascending from each of its 5 scale steps.
1. C-d-E-g-A-c-D-e-G 2. D-e-G-a-C-d-E-g-A 3. E-g-A-c-D-e-G-a-C
4. G-a-C-d-E-g-A-c-D 5. A-c-D-e-G-a-C-d-E
Ex 1. - Vertical View
A you can see, voicings / inversions 1., 2., 4. & 5., contain one Maj 3rd and three Perfect 4ths. The exception is 3., which is a stack of 4 Perfect 4ths, owing to the fact that the aforementioned Maj 3rd has been split between the top and bottom of the voicings. This illustrates, once again, the fundamental relationship between the interval of a P4th (5th), Pentatonic Scale, and the natural Harmonic Overtone Series.
Ex 2. - Arpeggiatedly Speaking...
Functionally, a C Maj Pentatonic - in these or any other forms - will work well over the following:
C Maj 6/9, C Maj7, D7 sus, F Maj7, A min7, Bb Maj7#11.
These are the more consonant, "inside" sounding examples. Adding different roots to the bottom (slash chords) can create some interesting colors.
