"I'm Leaving You"

I've been going through some old notes I never got around to writing about, and I found one from about two years ago about "I'm Leaving You."  In the line "I found somebody new, and I'm leaving you," the "leaving" is sung with a melisma (F E D E), musically giving a sense of movement (although it might be more metaphorical than literal).  "Leaving you" is also repeated at the end of the song, and the last time, it has a slightly different melisma (D E F E).
