C Kumoi Scale

What is the C Kumoi Scale?

The Kumoi scale is a Japanese pentatonic scale with a delicate, contemplative sound that originates from koto music of the Edo period. Its gentle blend of minor 2nd and major intervals creates a wistful, introspective mood that works beautifully for clean-tone passages, ambient textures, and any time you want an Eastern-tinged melodic voice. Here's how the C Kumoi Scale lays out on the fretboard.

Notes and Positions

Japanese pentatonic with a bittersweet minor quality. On bass, the fretboard view helps you visualize where the important tones sit for building lines across positions. Use a finger-per-fret approach first, then add shifts only when the line needs a wider range. In the key of C, the notes are: C, D, Eb, G, A.

How to Use It

You'll often hear it in Japanese Traditional, Ambient, and Jazz. A good way to internalize the sound is to sing the root, then sing a few scale degrees before you play them.

Practice root-on-E and root-on-A boxes separately, then connect them with one clean position shift. Use the interactive fretboard above to spot repeats of the same note on different strings and frets.
