The "T-Drop" (4̂-3̂-6̂)
Swift has her own melodic signature [...]: a three-note melodic motif [usually descending from 4̂ to 3̂ and then to 6̂] that we've termed the "T Drop."
— Nate Sloan & Charlie Harding, Switched On Pop (2020), p. 22
It first appears in You Belong With Me (2008) and is a consistent feature of her writing since then.
