Degrees
| Degree | Note | Interval | Semitones | Role |
|---|---|---|---|---|
| 1 | D♭ | perfect unison | 0 | The root — the tonal centre every other note is heard against; land on it and the sound resolves. |
| ♭3 | F♭ | 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. |
| 5 | A♭ | perfect fifth | 7 | The perfect fifth — the root's strongest companion; it anchors every triad and stacked-seventh quality. |
| 6 | B♭ | 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. |
| 9 | E♭ | major ninth | 14 | The major ninth — the second degree an octave up; it adds shimmer to maj9, 6/9 and the m9 family without changing the harmony. |
About this arpeggio
The minor 6/9 chord stacks a major sixth and a major ninth on a minor triad, with no seventh at all. It is one of the most beautiful and least understood qualities in the dictionary: dark at the bottom, sweet on top, and utterly settled. Jazz players use it as a tonic minor that never asks to resolve; soul and bossa nova use it as a shimmering landing point. The ninth softens the minor third's bite while the sixth keeps the dorian brightness. The shape is compact and lies well on the neck, which makes it a rewarding arpeggio to explore slowly. Listen for the major sixth and ninth together — that is the glow.
How to practise this arpeggio
- Play the sixth and ninth together at the top and listen for the glow.
- Compare it with m6 and hear what the added ninth does.
- Use it as a final minor chord and sustain the ninth.
- Comp it over a bossa nova and let the top two notes sing.
