A# Octatonic W-H Scale: Degrees, Notes, Intervals, and Practical Use

A# Octatonic W-H — octatonic W-H from “A#”, classic diminished sound. Great for building tension and smooth resolutions. Keep key tones in upper voice.

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.
