A# Aeolian Scale: Degrees, Notes, Intervals, and Practical Use

A# Aeolian — expressive natural minor from “A#” with gentle drama and familiar tone. Ideal for ballads, indie, and soundtracks. Arpeggios, legato, and smooth pedal tones work beautifully.

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 A# Aeolian Scale

Degree formula: 1 — 2 — b3 — 4 — 5 — b6 — b7. Interval pattern between adjacent degrees: 2 — 1 — 2 — 2 — 1 — 2 — 2. The scale includes the following notes:

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

  • C — gentle melodic extension and natural upward step.

  • Db — minor third, lyrical tone and soft drama.

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

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

  • Gb — minor sixth, soft pull to 5 and warm tone.

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

Together these degrees form the core of the A# Aeolian mode and define its musical character.
