Also written B7sus4, B or B Dominant 7th Suspended 4th
B 7th suspended 4th contains B, E, F♯, and A. The 7th-fret shape requires a wide stretch, and the 2nd-fret inversion uses a full barre.
The same three notes, with a different one in the bass.
B 7th suspended 4th is built from the formula 1, 4, 5, ♭7. The perfect 4th between B and E gives it the suspended quality, and the minor 7th A adds a dominant pull. Compare it to B suspended 4th, which lacks the minor 7th.
B 7th suspended 4th acts as the V chord in E major, appearing in the I–IV–V–I progression E major–A major–B major–E major. It suits rock and blues bass lines that need a suspended dominant. Compare it to B minor to hear the difference between a suspended dominant and a minor chord.
The 7th-fret shape keeps B in the bass for a root-position sound. The B7sus4/F♯ inversion at the 2nd fret puts F♯ in the bass, which softens the chord and works well for a lighter texture.
B 7th suspended 4th is played at the 7th fret as 7 9 7 9: index finger on the E string at fret 7, ring finger on the A string at fret 9, middle finger on the D string at fret 7 and pinky finger on the G string at fret 9.
Tip — The 2nd-fret inversion requires barring all four strings while keeping the bass note F♯ clear.
