Why it sounds like that

The formula 1, 4, 5 replaces the third with a perfect fourth, removing major or minor quality. The fourth interval creates the suspended sound. Compare with F major, which has A instead of B♭.

What goes wrong with F suspended 4th?

  • Let the pinky collapse and mute the E string.
  • Press the index finger too hard, causing the A string to buzz.

When to use it

F suspended 4th works as a tonic substitute in F major, often in the I–IV–V–I progression: F–B♭–C–F. It suits pop and rock where the suspension adds motion. Use it before a F major to create a lift.

Changing to and from F suspended 4th

  • Slide the whole shape down one fret to the 7th fret to play E suspended 4th.

Which voicing to use

The 8th fret voicing has F in the bass and is the most complete. The Fsus4/B♭ inversion puts B♭ in the bass for a softer, less grounded sound. The Fsus4/C inversions place C in the bass, adding tension that wants to resolve upward.

Common questions

How is F suspended 4th written?

F suspended 4th is written Fsus or Fsus4. The symbol Fsus4 is the most explicit.

What is the difference between Fsus4 and Fsus2?

Fsus4 replaces the third with a fourth (B♭), while Fsus2 replaces it with a second (G). Fsus4 has a stronger pull to resolve to the major third.

Can I use F suspended 4th in place of F major?

Yes, but only when the melody does not need the major third. The suspension creates a floating quality that resolves when you return to F major.
