Formula
The chord tones in order from the root, with the interval each one forms above it.
| Degree | Note | Semitones | Interval from the root |
|---|---|---|---|
| 1 | A | 0 | Perfect unison |
| 9 | B | 2 | Major second |
| b3 | C | 3 | Minor third |
| 11 | D | 5 | Perfect fourth |
| 5 | E | 7 | Perfect fifth |
| b7 | G | 10 | Minor seventh |
Inversions
An inversion is the same set of notes with a different one in the bass. The last column gives the distance of each note above the bass note, in semitones.
| Inversion | Bass note | Degree in the bass | Notes above the bass | Semitones above the bass |
|---|---|---|---|---|
| root position | A | 1 | A – B – C – D – E – G | 0 2 3 5 7 10 |
| first inversion | B | 9 | B – C – D – E – G – A | 0 1 3 5 8 10 |
| second inversion | C | b3 | C – D – E – G – A – B | 0 2 4 7 9 11 |
| third inversion | D | 11 | D – E – G – A – B – C | 0 2 5 7 9 10 |
| fourth inversion | E | 5 | E – G – A – B – C – D | 0 3 5 7 8 10 |
| fifth inversion | G | b7 | G – A – B – C – D – E | 0 2 4 5 7 9 |
Playable voicings
These shapes were found by searching the fretboard of a standard-tuned guitar (E A D G B E) rather than copied from a chord book. The search allows every string to sound or to be muted, rejects any shape with a muted string between two sounding strings, rejects any shape whose fretted notes span more than four frets (a five-fret window), requires every chord tone to be present, and then sorts what remains with root-position shapes first and the most compact, lowest shapes next. The shapes shown are the first six of that ordering; other orderings are possible at the same frets.
| # | Shape (low string first) | Notes | Degrees | Bass | Span (frets) | Sounding strings |
|---|---|---|---|---|---|---|
| 1 | 5-5-5-5-5-7 | A D G C E B | 1 11 b7 b3 5 9 | A | 2 | 6 |
| 2 | 5-2-2-5-3-3 | A B E C D G | 1 9 5 b3 11 b7 | A | 3 | 6 |
| 3 | 5-3-2-4-3-3 | A C E B D G | 1 b3 5 9 11 b7 | A | 3 | 6 |
| 4 | 5-5-2-4-1-3 | A D E B C G | 1 11 5 9 b3 b7 | A | 4 | 6 |
| 5 | 5-3-5-7-5-7 | A C G D E B | 1 b3 b7 11 5 9 | A | 4 | 6 |
| 6 | 5-7-5-5-3-7 | A E G C D B | 1 5 b7 b3 11 9 | A | 4 | 6 |
Shape numbers run from the lowest string to the highest, so the left-hand number is the sixth string (low E) in standard tuning. Multiple shapes are listed because a chord can be voiced several ways, and because a lower position is not always the better sounding one.
