"Breathe Out, Breathe In"

This morning, I watched this Zombies concert from eleven years ago to-day.  Later, I was thinking about "Breathe Out, Breathe In," and I realized that the first line ("The city's sitting pretty") exhibits both consonance ("The city's sitting pretty") and assonance ("The city's sitting pretty") and that this euphony matches and perhaps even helps evoke the description "pretty."
