Which singer co-wrote Taylor Swift’s “august” with Jack Antonoff?

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

Swift and Antonoff had already collaborated on songs for several earlier albums, including 1989, Reputation, and Lover. For “august,” Antonoff created the instrumental first and sent it to Swift, who wrote the lyrics quickly and intuitively.

The song is part of Folklore’s fictional storytelling world rather than a direct autobiographical account. Swift used an imagined summer romance to explore longing, uncertainty, and the feeling of holding onto a relationship that was never fully hers.

Joe Alwyn is another important name in the production credits, but he is credited as a co-producer rather than as the song’s co-writer. Aaron Dessner also worked extensively on Folklore, while Justin Vernon appears on a different track, “Exile.”
