"I Wanna Be Free"

Yester-day I listened to The Monkees (specifically, the second disc of the deluxe edition), and I noticed a small thing about "I Wanna Be Free."  The "down" in the line "Without any strings to tie me down" has a melisma.  Instead of one syllable, it's sung to two, and the second syllable has a lower pitch than the first one (it's B to A).  The melody to which "down" is sung goes down, musically representing the tying down that's in the lyric.
