B 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 (C) to root, b6 (G) 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 B, ending each on the bare 5th (F#).

How to play B kumoijoshi on guitar

Open B is the root, open G sits a minor sixth above it, and the pair of E strings adds a fourth, so four strings drone in key. Roots also sit at fret 7 on the outer strings, which means an octave shape is available without moving your hand far. Fret 2 on the A string handles the low end. A capo at fret 2 rewrites the key as A, so any A fingering drops in. Position one runs out at fret 11.
