F#m/F chord on guitar

F#m/F (F sharp minor over F) is made of three notes: F# (root), A (minor third) and C# (perfect fifth). The slash means F is played as the lowest note.

The easiest F#m/F is the "barre at fret 2" shape. Lay your index finger flat across the 3rd (G) to the 1st (high E) string at fret 2. This is the barre. Put your middle finger on the 4th (D) string at fret 3 (F). Don't play the low E and A strings: skip them or mute them with a fretting finger.

F#m/F has no open-string shape, so every version needs a barre or a stretch. The easiest one is rated medium.

Only the third changes. F# major uses a major third and sounds bright; F# minor lowers that note by a half step, which makes it sound darker. The root and the fifth stay the same.

F#m/F belongs to 6 keys: D major (as the iii chord), E major (as the ii chord), A major (as the vi chord), C sharp minor (as the iv chord), F sharp minor (as the i chord) and B minor (as the v chord).

The minor triad swaps the major third for a minor third, which gives it a darker, sadder color.
