Play B7sus4 in the Studio →A B7sus4 chord contains the notes B, F#, A, E. It is built from the dominant 7th suspended 4th formula 1 - 4 - 5 - ♭7, with B as the root.
B7 is the dominant (V) of E, and the sus4 adds an E note (the fourth of B) right into the chord — so it's already reaching toward the tonic before it gets there. When it resolves to E major, part of the chord barely has to move, which makes the landing feel especially smooth.
