Theory behind the chord
Major seventh chords keep the bright major triad but add the leading tone a semitone below the root. The result is the soft, floating sound heard throughout bossa nova, soul and neo-soul. On Bmaj7 this structure sits on the root B, so the degrees 1 – 3 – 5 – 7 map onto B, D#, F# and A#.
