Two unusual chords appear in the refrain. The other chords in the song are nothing special, but these two are different, not the kind you can figure out by listening just a couple of times. At first I felt confused. To exaggerate a little, I felt betrayed, even. The total unexpectedness of the sounds shook me, unsettled me, like when a cold wind suddenly blows in through a crack. But once the refrain is over, that beautiful melody returns, taking you back to that original world of harmony and intimacy.
