What makes A♭ Hirajōshi different
Hirajōshi is a five-note scale (1, 2, ♭3, 5, ♭6): natural minor with the fourth and seventh left out. Unlike the minor pentatonic it keeps two half steps, between 2 and ♭3 and between 5 and ♭6, which give it its koto-like sound. It also has two gaps of a major third, ♭3 to 5 and ♭6 to the octave, so the scale alternates tight steps with wide leaps. That contrast is what makes it sound Japanese to Western ears rather than simply minor. On A♭, A♭ Hirajōshi is A♭ Natural Minor (A♭ B♭ C♭ D♭ E♭ F♭ G♭) without D♭ and G♭.
How to use the A♭ Hirajōshi scale
Because A♭ Hirajōshi has fewer or more than seven notes, it doesn't produce a standard set of seven diatonic triads. Instead, build chords by stacking thirds within the scale or use it as a melodic colour over chords drawn from a related diatonic key.
Hirajōshi is one of the most recognisable Japanese pentatonic scales - instantly evokes koto, shamisen and traditional folk music.
