G♭m(maj7)

G♭1B♭♭♭3D♭5F7

Minor triad, major seventh — the tonic chord of harmonic minor.

Written the other way round it is F♯m(maj7) — the same twelve keys on a piano, a different piece of notation.

What is true of it

G♭m(maj7) is G♭, B♭♭, D♭ and F — 1, b3, 5 and 7 counted from G♭.

B♭♭ is a double flat, and it has to be: every letter from G♭ upwards is used once, so the b3 cannot be written any other way.

On an instrument that cannot reach all 4, the 5 goes first, in that order.

The easiest of the 2 fingerings below is b998: 4 fingers, held at the 8th fret.

None of them uses an open string, so this chord moves up the neck unchanged — the same shape 1 fret higher is the chord a semitone above.

The brass dots are G♭, the root. Everything else is a chord tone with its degree printed in it.

An inversion is the same chord with a different note lowest. The name changes to a slash name because the bass is what a listener hears as the foundation.
