"And the Tide Rushes In"

In "And the Tide Rushes In," the melody to which the line "I build them up; you knock them down" is sung musically reflects the "build[ing]... up" and "knock[ing]... down."  "I build them up" is sung to an ascending phrase (E A A A), and the "down" in "you knock them down" is sung with a descending glissando (C# to A).
