G♭maj7

G♭1B♭3D♭5F7

Major triad with a major seventh: a half step below the root, an octave up.

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

What is true of it

G♭maj7 is G♭, B♭, D♭ and F — 1, 3, 5 and 7 counted from G♭.

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

The easiest of the 2 fingerings below is ba98: 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.

1 of the 2 need a barre.

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.
