Why it sounds like that

F♯ minor add 9 uses the formula 1, ♭3, 5, 9. The major 2nd between F♯ and G♯ adds the ninth, while the minor 3rd between F♯ and A keeps the minor quality. Compare with F♯ minor, which omits the ninth.

What goes wrong with F♯ minor add 9?

  • Letting the index barre lift off the high e string, causing a buzz at the 2nd fret.
  • Flattening the middle finger onto the 4th string and deadening the D at the 4th fret.

When to use it

F♯ minor add 9 works as the vi chord in A major, as in A–E–F♯m–D, the I–V–vi–IV. It suits bright, driving passages where the added ninth adds a sparkling top note.

Changing to and from F♯ minor add 9

  • Sliding the shape up one fret to the 3rd fret gives G minor add 9.
  • From F♯ minor, lift the pinky and middle finger to return to the 2nd-fret F♯ minor barre.

Which voicing to use

The 2nd-fret voicing puts F♯ in the bass for a root-position sound. The F♯m add9/A inversion at the 1st fret places A in the bass, giving a darker, less stable feel.
