Also written F7sus4, F or F Dominant 7th Suspended 4th
F 7th suspended 4th contains F, B♭, C, and E♭. The 1st-fret shape demands a wide stretch, and the 8th-fret inversion requires a full barre.
The same three notes, with a different one in the bass.
F 7th suspended 4th is built from the formula 1, 4, 5, ♭7. The perfect 4th between F and B♭ creates the suspended sound, while the minor 7th E♭ adds tension. Compare it to F suspended 4th, which omits the minor 7th.
F 7th suspended 4th functions as the V chord in B♭ major, heard in the I–IV–V–I progression B♭ major–E♭ major–F major–B♭ major. It fits blues and rock bass lines that need a suspended dominant. Compare it to F minor to hear the difference between a suspended dominant and a minor chord.
The 1st-fret shape keeps F in the bass for a strong root position. The F7sus4/C inversion at the 8th fret puts C in the bass, which gives a softer, less grounded feel.
F 7th suspended 4th is played at the 1st fret as 1 3 1 3: index finger on the E string at fret 1, ring finger on the A string at fret 3, middle finger on the D string at fret 1 and pinky finger on the G string at fret 3.
Tip — The 8th-fret inversion requires barring all four strings cleanly while keeping the bass note C clear.
