Why it sounds like that

F 7th suspended 4th is built from the formula 1, 4, 5, ♭7. The perfect 4th between F and B♭ replaces the major 3rd, suspending the chord. Compare it to F suspended 4th, which omits the minor 7th.

What goes wrong with F 7th suspended 4th?

  • Buzzing on the B or high E string because the barre is uneven.
  • Letting the pinky flatten and touch the D or B string, muting them.

When to use it

F 7th suspended 4th works as the V chord in B♭ major, resolving to B♭ major in a I–IV–V–I progression. It also fits F minor and F 5th contexts. The suspended 4th creates tension before a resolution to F major.

Changing to and from F 7th suspended 4th

  • Move to F minor by lifting the pinky and placing it on the G string at the 1st fret, while keeping the barre at the 1st fret.

Which voicing to use

The 1st fret barre voicing is the default and keeps F in the bass. The F7sus4/B♭ inversion at the 1st fret puts B♭ in the bass, softening the root. Choose the root-position shape for a firm foundation.

Common questions

What mistake do players make with the F7sus4 barre?

The pinky often fails to press the G string at the 3rd fret cleanly, causing a muted note. Keep the pinky arched and close to the fret.

How does F7sus4 differ from F minor 7th?

F7sus4 replaces the minor 3rd A♭ with the perfect 4th B♭. F minor 7th contains A♭, while F7sus4 contains B♭, creating a suspended sound.

Is there an easier F7sus4 voicing than the 1st fret barre?

The F7sus4/B♭ inversion at the 1st fret uses a partial barre and omits the low E string, making it easier for some players. It puts B♭ in the bass, which changes the sound.
