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	3-1-3-3-3-1 (6→1)	G A# F A# D F	1 b3 b7 b3 5 b7	G	2	6
2	3-1-3-3-3-3 (6→1)	G A# F A# D G	1 b3 b7 b3 5 1	G	2	6
3	3-5-3-3-3-3 (6→1)	G D F A# D G	1 5 b7 b3 5 1	G	2	6
4	15-13-15-15-15-13 (6→1)	G A# F A# D F	1 b3 b7 b3 5 b7	G	2	6
5	15-13-15-15-15-15 (6→1)	G A# F A# D G	1 b3 b7 b3 5 1	G	2	6
6	3-1-0-0-3-1 (6→1)	G A# D G D F	1 b3 5 1 5 b7	G	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.
