"It's So Easy Falling"

The repeated line "Falling in love with you" in the choruses of "It's So Easy Falling" is sung to a descending melody spanning an octave:  A G F F C Bb A ("love" is sung with a melisma [F C], and "you" is sung with a melisma the first time only [instead of the final A above, it's A Bb A G A]).  While "falling" is used metaphorically here, there's a sense of its meaning because of that descent.

"Run" in the line "I say that I can't take no more; I've said it more than once before, and I never run" is also sung with a melisma (D Bb C, I think), so while it's negated, there's a sense of movement.
