B Aeolian Mode

What is the B Aeolian Mode?

The Aeolian mode is the sixth mode of the major scale and is identical to the natural minor scale. Thinking of it as a mode helps you understand its relationship to the other six modes and makes it easier to shift between modal colors when improvising over diatonic progressions. Here's how the B Aeolian Mode lays out on the fretboard.

Notes and Positions

The sixth mode - identical to the natural minor scale. Sad and introspective. On bass, this scale becomes a toolkit for strong roots, passing tones, and melodic fills that still support the groove. Think in root-on-E and root-on-A boxes, then adapt the same notes for 5-string bass when the low B string gives you another root below the pattern. In the key of B, the notes are: B, C#, D, E, F#, G, A.

How to Use It

You'll often hear it in Rock, Metal, Classical, and R&B. A good way to internalize the sound is to sing the root, then sing a few scale degrees before you play them.

Loop a simple drum groove and keep every note locked to the subdivision before adding fills. Use the interactive fretboard above to spot repeats of the same note on different strings and frets.
