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 | Eb | 1 | Eb – F – G – Bb – C – Db | 0 2 4 7 9 10 |
| first inversion | F | 9 | F – G – Bb – C – Db – Eb | 0 2 5 7 8 10 |
| second inversion | G | 3 | G – Bb – C – Db – Eb – F | 0 3 5 6 8 10 |
| third inversion | Bb | 5 | Bb – C – Db – Eb – F – G | 0 2 3 5 7 9 |
| fourth inversion | C | 13 | C – Db – Eb – F – G – Bb | 0 1 3 5 7 10 |
| fifth inversion | Db | b7 | Db – Eb – F – G – Bb – C | 0 2 4 6 9 11 |
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 | 11-10-10-10-11-9 | Eb G C F Bb Db | 1 3 13 9 5 b7 | Eb | 2 | 6 |
| 2 | 11-13-11-12-13-13 | Eb Bb Db G C F | 1 5 b7 3 13 9 | Eb | 2 | 6 |
| 3 | 11-10-11-10-11-8 | Eb G Db F Bb C | 1 3 b7 9 5 13 | Eb | 3 | 6 |
| 4 | 11-8-10-12-11-9 | Eb F C G Bb Db | 1 9 13 3 5 b7 | Eb | 4 | 6 |
| 5 | 11-8-11-12-11-8 | Eb F Db G Bb C | 1 9 b7 3 5 13 | Eb | 4 | 6 |
| 6 | 11-13-10-12-14-13 | Eb Bb C G Db F | 1 5 13 3 b7 9 | Eb | 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.
