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.
