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 | D | 1 | D – F – A – C# – E | 0 3 7 11 2 |

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 | 10-12-11-10-10-12 | D A C# F A E | 1 5 7 b3 5 9 | D | 2 | 6 |
| 2 | 10-7-7-10-10-9 | D E A F A C# | 1 9 5 b3 5 7 | D | 3 | 6 |
| 3 | 10-8-7-9-10-9 | D F A E A C# | 1 b3 5 9 5 7 | D | 3 | 6 |
| 4 | 10-8-11-9-10-9 | D F C# E A C# | 1 b3 7 9 5 7 | D | 3 | 6 |
| 5 | 10-8-11-9-10-10 | D F C# E A D | 1 b3 7 9 5 1 | D | 3 | 6 |
| 6 | 10-7-7-6-6-9 | D E A C# F C# | 1 9 5 7 b3 7 | D | 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.
