Perhaps you are already comfortable playing standard triad type chords on a keyboard. A triad is a three note chord.
This B7 chord shown on piano adds another note in to make a four note chord. Play all four notes with one hand only but practice the chord with both hands. If you'd like to get a little movement going practice moving from an E Major chord to the B7, or from a c# minor to the B7.
