B Bebop Dominant Scale

What is the B Bebop Dominant Scale?

The bebop dominant scale adds a passing natural 7th to the Mixolydian mode, creating an eight-note scale designed for one specific purpose: keeping chord tones landing on downbeats when you play running eighth notes. It was pioneered by Charlie Parker and Dizzy Gillespie and remains essential vocabulary for jazz improvisation. Here's how the B Bebop Dominant Scale lays out on the fretboard.

Notes and Positions

Mixolydian with added major 7 for even eighth-note phrasing. 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, A#.

How to Use It

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

Build two-bar bass lines that return to the root before experimenting with wider melodic movement. Use the interactive fretboard above to spot repeats of the same note on different strings and frets.
