Which co-writer helped Taylor Swift write “august” for Folklore?

Jack Antonoff co-wrote “august” with Taylor Swift for Folklore.

Antonoff created the instrumental first and sent it to Swift, who wrote the lyrics on the spot. The collaboration continued a working relationship that had already produced songs for Swift’s albums 1989, Reputation, and Lover.

Swift and Antonoff are the song’s listed songwriters. They also handled its principal production, with Joe Alwyn additionally credited as a producer. Aaron Dessner was a major Folklore collaborator, but he is not credited as a writer of “august.”

The song’s finished sound combines Antonoff’s layered, atmospheric production with Swift’s fictional storytelling. That partnership helped give “august” its dreamlike late-summer mood and its place within Folklore’s interconnected narratives.
