I listened to
Pet Sounds yester-day to mark the sixtieth anniversary of its release, and I noticed a small point in "I Know There's an Answer." "Better" in the line "And tell them the way that they live could be better" is sung with a melisma (G Eb C Bb), and this articulation lends a sense of the comparative nature of the adjective (more notes for a greater degree).
Later, I noticed that "day" and "night" in the line "They trip through the day and waste all their thoughts at night" form something of a temporal merism.
