What makes G♭ Kumoi different
Kumoi (1, 2, ♭3, 5, 6) has a minor third but a major sixth, and no fourth or seventh. That pairing is the Dorian colour, and every note of Kumoi belongs to Dorian on the same root. Its only half step, between 2 and ♭3, sits low in the scale, and above it the scale moves in a major third, a whole step and a minor third. Hirajōshi has the same shape except for the sixth: ♭6 there, 6 here. On G♭, G♭ Kumoi is G♭ Dorian (G♭ A♭ B𝄫 C♭ D♭ E♭ F♭) without C♭ and F♭.

Because G♭ Kumoi 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.
