In "So Deep within You," "night" in the line "My heart is heavy; it's weighed down by the night" is sung with a descending melisma (C# A). Musically, this gives a sense of the weight with which the heart is "weighed down."
In the next verse, "shared" in the line "Warm colors flowing, this feeling we have shared" is sung with the same melisma, but here it gives a sense of the word's meaning since "shared" is distributed between those two notes.
