B suspended 4th chord on bass (Bsus4)
Also called or written Bsus4, Bsus or B Suspended
B suspended 4th contains B, E, and F♯. The 7th-fret shape is a stretch, but the inversion at the 2nd fret uses a barre for a warmer voicing.

Why it sounds like that
B suspended 4th is built from the formula 1, 4, 5 — the root B, the perfect fourth E, and the perfect fifth F♯. The fourth replaces the third, which removes the major or minor quality and leaves an open, unresolved sound. Compare it with B major, where the third is D♯.
What goes wrong with B suspended 4th?
- Letting the pinky collapse and mute the 1st string.
- Pressing the middle finger too flat and deadening the 2nd string.
- Rushing the shift so the index lands short of the 7th fret.
When to use it
B suspended 4th works as a suspended colour in B major progressions like B–E–F♯–B, the I–IV–V–I, where it delays the resolution of B major. It also fits rock, pop, and gospel when a chord needs to hover before landing.
Changing to and from B suspended 4th
- Move to B major by lifting the middle finger and placing it on the 3rd string, 8th fret while keeping the index and ring in place.
- Slide the shape down two frets to the 5th fret to reach A suspended 4th.
Which voicing to use
The 7th-fret shape puts B in the bass for a rooted, stable sound. The Bsus4/F♯ inversion places F♯ in the bass, which softens the chord and works well when the bass line is descending toward E.
