I'd previously noted the sort of parallelism in the line "Walk in the light of day and talk the night away" in "I'll Call You Mine," but early last month, I was thinking about this again and started wondering if these phrases were also parallel musically. I'd forgotten about this until recently, but yester-day, I figured out the vocal melody for the first two verses in order to investigate this.
The two halves of the line begin the same way (G# A B), and the last few notes of each, while not exactly the same, trace a diatonic descent (F E D and E D C), so there is a bit of musical parallelism that matches the sort of parallelism in the lyrics.
I was also struck by how much of the melody occurs on the off-beats, and I think this may be significant in light of the lyrics. The second verse (repeated as the third verse) ends with the line "I was afraid to try to call you mine," and this delivery that comes just after the beat seems to indicate the narrator's hesitancy and reluctance.
