In the lines "My mind is singing / With all we've said" in "Beginning," the phrase "all we've said" is sung to notes of all different pitches (E F# G), lending a sense of breadth or entirety.
The same sort of effect is in the line "Ev'rything falls in the middle," where "ev'rything" is also sung to notes of all different pitches (A B C).
I referenced the version on The Ghost of You and Me and discovered that it's in a different key, so while these features are present there, too, the specific pitches are different (D E F and G A Bb, respectively).
