What color?

A Japanese pentatonic with half steps (R 9 b3 5 b13): a low, contemplative minor color, the iconic sound of the koto. The b6 against the 5 creates its characteristic tension.

Origin & history

A Japanese pentatonic scale associated with the traditional tunings of the koto (zither) and the shamisen. Its half steps give it the melancholy color typical of Japanese chamber music.

Which chords to play it on?

Outside the functional consensus: this is an exploration color. Lay it over a vamp or a held chord to tint your improvisation with an unexpected flavor, rather than inside a cadence.
