guitar chord
F♯maj7
Major triad with a major seventh: a half step below the root, an octave up.
Written the other way round it is G♭maj7 — the same twelve keys on a piano, a different piece of notation.

What is true of it
F♯maj7 is F♯, A♯, C♯ and E♯ — 1, 3, 5 and 7 counted from F♯.
On an instrument that cannot reach all 4, the 5 goes first, in that order.
The easiest of the 5 fingerings below is 243322: 4 fingers, one of them barring the 2nd fret, held at the 2nd 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.
2 of the 5 need a barre.
Where its notes are on the neck
The brass dots are F♯, 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.
