A sharp 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♯ (A sharp) | root |
| 2 | B | minor second |
| 3 | C♯ (C sharp) | minor third |
| 4 | D♯ (D sharp) | perfect fourth |
| 5 | E | diminished fifth |
| 6 | F♯ (F sharp) | minor sixth |
| 7 | G♯ (G sharp) | 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 major scale, starting from another degree.
