Why it sounds like that

F♯ suspended 2nd is built from the formula 1, 2, 5. The Major 2nd between F♯ and G♯ replaces the third, creating an open, unresolved quality. Compare with F♯ major, which uses a Major 3rd instead.

What goes wrong with F♯ suspended 2nd?

  • The D string is muted because the barre finger is not pressing evenly across the 4th fret.
  • The pinky accidentally touches the D string, dulling the note at the 4th fret.

When to use it

F♯ suspended 2nd works as a passing chord in F♯ major, especially in the I–IV–V–I progression: F♯ major–B major–C♯ major–F♯ major. Its open sound suits rock, metal, and progressive bass lines.

Changing to and from F♯ suspended 2nd

  • Sliding the shape down two frets to the 2nd fret gives E suspended 2nd.
  • Move to F♯ major by lifting the pinky and shifting the barre to fret 4 on the E string while fretting A♯ on the A string at fret 6.

Which voicing to use

The 4th-fret voicing puts G♯ in the bass, which is useful when the chord needs to lead to C♯. The 9th-fret voicing puts C♯ in the bass and is easier to reach in mid-neck positions.

Common questions

How is F♯ suspended 2nd written?

F♯ suspended 2nd is written as F♯sus2 or F♯. On a keyboard, type F# because the ♯ symbol is not available. It is also spelled G♭ in enharmonic notation for the same sounding root.

How does F♯ suspended 2nd differ from F♯ suspended 4th?

F♯ suspended 2nd replaces the third with a Major 2nd (G♯), while F♯ suspended 4th replaces it with a Perfect 4th (B). The sus2 sounds brighter and more open; the sus4 has a stronger pull to resolve.

What is the difference between F♯ suspended 2nd and F♯ add 9?

F♯ suspended 2nd omits the third entirely, leaving F♯, G♯, and C♯. F♯ add 9 includes the major third (A♯) along with the ninth (G♯), so it has a fuller, more consonant sound.
