Gb Bebop Dominant Scale

What is the Gb 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 Gb Bebop Dominant Scale lays out on the fretboard. This scale is enharmonically equivalent to F# Bebop Dominant.

Notes and Positions

Mixolydian with added major 7 for even eighth-note phrasing. 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 Gb, the notes are: Gb, Ab, Bb, Cb, Db, Eb, Fb, F.

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.

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.
