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 | 2-0-1-2-2-2 | Gb A Eb A Db Gb | 1 b3 6 b3 5 1 | Gb | 2 | 6 |
| 2 | 2-4-4-2-4-2 | Gb Db Gb A Eb Gb | 1 5 1 b3 6 1 | Gb | 2 | 6 |
| 3 | 14-12-13-14-14-14 | Gb A Eb A Db Gb | 1 b3 6 b3 5 1 | Gb | 2 | 6 |
| 4 | 2-4-1-2-2-2 | Gb Db Eb A Db Gb | 1 5 6 b3 5 1 | Gb | 3 | 6 |
| 5 | 2-4-1-2-4-2 | Gb Db Eb A Eb Gb | 1 5 6 b3 6 1 | Gb | 3 | 6 |
| 6 | 2-4-4-2-4-5 | Gb Db Gb A Eb A | 1 5 1 b3 6 b3 | Gb | 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.
