Formula and Intervals of the Gb Dorian Scale
Degree formula: 1 — 2 — b3 — 4 — 5 — 6 — b7. Interval pattern between adjacent degrees: 2 — 1 — 2 — 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.
- A — minor third, lyrical tone and soft drama.
- 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 Dorian mode and define its musical character.
