Fingering charts

The library holds 5 fingerings of this chord and all of them are shown, in the library’s own order. Several fingerings of one chord is normal: the same notes can be stopped at different positions and on different strings.

Formula

The chord tones in order from the root, with the interval each one forms above it.

Degree	Note	Semitones	Interval from the root
1	G♭	0	Perfect unison
5	D♭	7	Perfect fifth

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	G♭	1	G♭ – D♭	0 7
first inversion	D♭	5	D♭ – G♭	0 5

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	2-4-4-6-2-2 (6→1)	Gb Db Gb Db Db Gb	1 5 1 5 5 1	Gb	4	6
2	2-4-4-6-2-x (6→1)	Gb Db Gb Db Db x	1 5 1 5 5 x	Gb	4	5

6	x-9-11-11-7-x (6→1)	x Gb Db Gb Gb x	x 1 5 1 1 x	Gb	4	4

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.
