C♭ Kumoi Scale: Notes, Piano & Guitar

C♭ Kumoi at a glance

Kumoi is a beloved Japanese pentatonic that anime, game and film composers reach for when they want a Japanese flavour without the obvious cliché of Hirajōshi. Sounds calm and slightly ambiguous. Built on the root C♭, the scale takes on the specific colour and pitch range of that key - making it especially useful in genres and registers where C♭ is a comfortable tonal centre.

What makes C♭ 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 C♭, C♭ Kumoi is C♭ Dorian (C♭ D♭ E𝄫 F♭ G♭ A♭ B𝄫) without F♭ and B𝄫.
