A Locrian mode on piano
The Locrian mode, with its minor second and flat fifth, is the most unstable mode. It is mostly used over half-diminished chords, in jazz and metal.
On the keyboard
Numbers above the keys are the scale degrees; the root is filled.
Notes of the scale
| Degree | Note | Interval |
|---|---|---|
| 1 | A | root |
| 2 | B♭ (B flat) | minor second |
| 3 | C | minor third |
| 4 | D | perfect fourth |
| 5 | E♭ (E flat) | diminished fifth |
| 6 | F | minor sixth |
| 7 | G | minor seventh |
Steps between notes: H – W – W – H – W – W – W (W = whole step, H = half step)
This mode uses the same notes as the B flat major scale, starting from another degree.
