C kumoijoshi

The kumoijoshi scale is a Japanese koto tuning turned scale: root, flat 2nd, 4th, 5th, flat 6th. The two half steps (b2 against the root, b6 against the 5th) do all the work, giving it the sparse, haunting quality of traditional koto music. Guitarists use it for dramatic intros and as a fresh melodic angle over minor chords.

it consists of these notes and degrees:

tip
  • A koto tuning turned scale: sparse by design, so let notes ring into each other like open strings.
  • The two half steps (b2 (Db) to root, b6 (Ab) to V) do all the expressive work; approach both slowly and resolve down.
  • Play it as arpeggiated open-position clusters near the nut with the root on an open string when the key allows.
  • Dramatic intro trick: rubato phrases over a suspended root drone on C, ending each on the bare 5th (G).

How to play C kumoijoshi on guitar

Open G rings a perfect fifth over the root and it is the only open string in this key, so one free drone is all you get. Roots land at fret 8 on both E strings, fret 3 on the A and fret 1 on the B, which means the low shape has anchors at either end. Fret 5 on the G string fills the gap. Move the identical fingering up 7 semitones and it reads as G iwato, so the grip does double duty. Position work stays put until fret 12.
