Gb Mixolydian Scale: Degrees, Notes, Intervals, and Practical Use

Gb Mixolydian — dominant major from “Gb” with bluesy flavor and natural pull to tonic. Good for rock and groovy lines. Emphasize b7, add 9/13 in upper voices.

To visually explore a scale, use the interactive circle of fifths — it shows the relationships between notes, chords, and degrees, helping you understand its structure. Next to the circle, you’ll find the guitar fretboard, where all notes of the selected mode are displayed in the same colors as on the circle. Below, you can see the chords that belong to this scale — with degree labels and chord shape thumbnails that you can open and listen to. You can change the guitar tuning, fretboard orientation, and the display mode for notes or intervals. Detailed instructions on how to use the tool are available on the main Circle of Fifths page — check it out to make the most of all its features.

Formula and Intervals of the Gb Mixolydian Scale

Degree formula: 1 — 2 — 3 — 4 — 5 — 6 — b7. Interval pattern between adjacent degrees: 2 — 2 — 1 — 2 — 2 — 1 — 2. The scale includes the following notes:

  • Gb — tonic, the main anchor of the mode.

  • Ab — gentle melodic extension and natural upward step.

  • Bb — major third, clear support above the tonic.

  • B — quartal spice, best separated from 3 by voice leading.

  • Db — perfect fifth, stabilizing anchor of the mode.

  • Eb — warm upper shade, pairs well with 9.

  • E — dominant pull toward tonic, typical of Mixolydian.

Together these degrees form the core of the Gb Mixolydian mode and define its musical character.
