"You Know What to Do"

In the line "I watched you walkin' by, and you looked all alone" in "You Know What to Do," there's alliteration in "all alone."  Because there's only one initial sound, there's a representation of that singularity.  "Alone" is also sung with a melisma (C# C# B), giving a sense of degree.

"Day" in the line "Understand I'll stay with you ev'ry day" is sung with a melisma (C# B), giving a sense of frequency.  There's a similar feature with "way" (also sung with a C# B melisma) in the following line:  "Make you love me more in every way," but here "every" is sung with three syllables, which also gives a sense of amount.
