I do not want you to miss this point: during the entire chorus, the downbeat has been empty. It’s blank. It’s a blank space. Do you get it? The downbeat is a blank space, baby.
But I got a blank space baby
*pen click*
And I’ll write your name
BOOM. And with the final word we come crashing down like a nuclear bomb onto the downbeat. She teased us for 15 lines, but with the final word she gives us sweet, blissful release.It is also the singular moment we realize that both Taylor Swift and the protagonist have been in control the entire time. We were lured in by the seductive, stable protagonist (verse), slowly realized she was unstable (chorus), but we come running back the moment she fills her blank space (the downbeat) with our name.
