Pentatonic b6 Combination Exercise
This pretty little combination exercise, which unlocks the door and lets you get "up close and personal" with the Pentatonic b6 scale and its modes, is similar in construction to an exercise which I posted previously, based on the Pentatonic b2 scale.
While the Penta b2 could be considered as a derivative of the 8 note diminished scale system (as well as the lesser used Harmonic Major scale), the Penta b6 is derived from the Melodic Minor harmonic system (scale steps 5-6-7-9-b3), but also found as part of Harmonic Major (scale steps 1-2-3-5-b6).
As its name suggests, the Penta b6 is a 5 note pentatonic scale with the 6th (as being the interval measured from its root, not its scale step), flatted (eg. G Penta b6 = G-A-B-D-Eb, derived from C Melodic Minor or G Harmonic Major).
