Watch the Exploring Hirajoshi & More Pentatonics online guitar lesson by Sean McGowan from Pentatonic Palettes for Jazz Guitar

There are many different pentatonic scales available to use in improvisation, and another colorful pentatonic that in root position implies a natural minor (Aeolian) sound is the Hirajoshi. It is a fantastic alternative to the Kumoi, and also can be easily applied to more common harmonic settings such as Major7/Lydian#11 chords, m7(b5)/Locrian chords, etc. You'll be surprised at how much your phrasing is affected by thinking of and employing these pentatonic regions and substitutions, as opposed to modes.
