Degrees
| Degree | Note | Interval | Semitones | Role |
|---|---|---|---|---|
| 1 | A | perfect unison | 0 | The root — the tonal centre every other note is heard against; land on it and the sound resolves. |
| ♭2 | B♭ | minor second | 1 | The minor second — a half-step above the root and the sharpest tension in the box; phrygian and the altered scale lean on it. |
| ♭3 | C | minor third | 3 | The minor third — the dark counterpart of the major third; it turns a shape minor and colours m, m7 and the minor scales. |
| 4 | D | perfect fourth | 5 | The perfect fourth — stable yet suspended; in sus4 it takes the third's place and leaves the chord hanging. |
| ♭5 | E♭ | diminished fifth | 6 | The diminished fifth — a flattened fifth that destabilises the chord; dim, m7♭5 and locrian are built on it. |
| 6 | F♯ | major sixth | 9 | The major sixth — the hopeful note that separates dorian and m6 from their darker cousins; it sits a whole step above the fifth. |
| ♭7 | G | minor seventh | 10 | The minor seventh — the dominant's engine; a whole step under the root, it turns a triad into a 7 chord and drives the resolution. |
About this scale
Locrian natural six is the second degree of harmonic minor: the unstable locrian shape with a raised sixth that softens the darkness. The flat second and flat fifth remain, but the natural sixth removes the harshest edge and gives the scale a warm, bittersweet quality. It is the sound of the m7♭5 chord when the harmony wants to move smoothly, and the standard scale for the ii chord in a minor ii–V–i where the natural sixth avoids the augmented interval. Jazz players use it over half-diminished chords that resolve to a dominant. Listen for the sixth brightening the flat fifth's gloom.
How to practise this scale
- Play the natural sixth and hear it soften the flat fifth.
- Improvise over an m7♭5 chord that resolves through a minor ii–V.
- Compare it with locrian and hear what the raised sixth changes.
- Play the scale slowly and listen for the absence of the augmented second.
