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 | Bb | 1 | Bb – Db – F – G | 0 3 7 9 |
| first inversion | Db | b3 | Db – F – G – Bb | 0 4 6 9 |
| second inversion | F | 5 | F – G – Bb – Db | 0 2 5 8 |
| third inversion | G | 6 | G – Bb – Db – F | 0 3 6 10 |
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 | 6-4-5-6-6-6 | Bb Db G Db F Bb | 1 b3 6 b3 5 1 | Bb | 2 | 6 |
| 2 | 6-8-8-6-8-6 | Bb F Bb Db G Bb | 1 5 1 b3 6 1 | Bb | 2 | 6 |
| 3 | 6-4-3-3-6-3 | Bb Db F Bb F G | 1 b3 5 1 5 6 | Bb | 3 | 6 |
| 4 | 6-4-5-3-6-3 | Bb Db G Bb F G | 1 b3 6 1 5 6 | Bb | 3 | 6 |
| 5 | 6-4-3-6-6-3 | Bb Db F Db F G | 1 b3 5 b3 5 6 | Bb | 3 | 6 |
| 6 | 6-4-5-3-6-6 | Bb Db G Bb F Bb | 1 b3 6 1 5 1 | Bb | 3 | 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.
