This morning I was thinking about "Twilight," and I discovered a small feature in the lines "It's either real, or it's a dream / There's nothing that is in between." It's sung to this melody:
Musically, this portrays that "nothing... in between" because it's a conjunct melody: it goes up and down according to the steps of the scale and doesn't skip over any notes. Disregarding accidentals, there are no notes "in between" these.
