Extended
A 11th chord
A dominant chord extended to the eleventh. Big, suspended and hazy — the third is usually left out in practice.
Notes in A 11th
| Note | Interval | Semitones from root |
|---|---|---|
| A | Root | 0 |
| C# | Major 3rd | 4 |
| E | Perfect 5th | 7 |
| G | Minor 7th | 10 |
| B | Major 9th | 14 |
| D | Perfect 11th | 17 |
Formula: 0–4–7–10–14–17 semitones above the root. Move the whole shape up or down and you get the same chord in another key — that is why 11th chords sound alike no matter where they start.
