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 E.

What goes wrong with F♯ 7th suspended 4th?

The 2nd string buzzes because the index finger is too far from the fret.
The 1st string is muted by the pinky collapsing onto it.
The 4th string sounds dull because the middle finger is not pressing firmly.

When to use it

F♯ 7th suspended 4th works as the V chord in B major progressions like B–E–F♯–B, the I–IV–V–I. It suits rock, blues, and folk feels. Compare it to F♯ minor to hear the difference in color.

Changing to and from F♯ 7th suspended 4th

Sliding the shape down one fret to the 1st fret gives F 7th suspended 4th.
Sliding the shape up one fret to the 3rd fret gives G 7th suspended 4th.

Which voicing to use

The B inversion places the 4th in the bass, giving a grounded sound. The E inversion, with the 7th in the bass, is darker and less stable. Choose the B inversion for a fuller voicing.

Common questions

How is F♯ 7th suspended 4th written?

F♯ 7th suspended 4th is written F♯7sus4 or F♯. On a keyboard, use F#7sus4. It is also spelled G♭ in enharmonic notation for the same sounding root.

What is the difference between F♯7sus4 and F♯7?

F♯7sus4 replaces the major 3rd A♯ with the perfect 4th B. This removes the leading tone and creates a suspended, unresolved sound.

Can F♯7sus4 be used in place of F♯7?

Yes, F♯7sus4 often substitutes for F♯7 in dominant contexts. The suspension delays the resolution to the tonic chord.
