A Locrian
7-note Locrian scale on A — A, A♯, C, D, D♯, F, G.
Press to hear the scale played ascending.
The darkest mode — flat second and flat fifth both. Built on a diminished triad, it is rarely a home key, more a colour to pass through.
The notes
Each degree links to its pitch page. Note names use sharp spelling throughout — every accidental is written as a sharp (C♯, not D♭), the same convention as the note pages.
Degrees & steps
| Degree | Note | Semitones from root | Step to next |
|---|---|---|---|
| 1 | A | 0 | half |
| ♭2 | A♯ | 1 | whole |
| ♭3 | C | 3 | whole |
| 4 | D | 5 | half |
| ♭5 | D♯ | 6 | whole |
| ♯5 | F | 8 | whole |
| ♭7 | G | 10 | whole |
The step formula is 1–2–2–1–2–2–2 semitones — 7 steps that sum to a full octave (12 semitones) and return to A.
