Which musician besides Taylor Swift is credited as a co-writer of “august”?

Jack Antonoff is credited as a co-writer of Taylor Swift’s “august.”

Swift and Antonoff wrote the song together, continuing a collaboration that had already produced songs on 1989, Reputation, and Lover. For “august,” Antonoff first created the instrumental and sent it to Swift, who wrote the lyrics quickly and intuitively in response to the music.

A frequent source of confusion is the song’s production credits. Joe Alwyn is also credited as a producer, but he is not listed as a songwriter for “august.” Aaron Dessner was another major Folklore collaborator, yet he did not co-write this particular track. These overlapping album credits can make the song’s personnel difficult to remember.

Antonoff’s role was both musical and compositional. He contributed to the instrumental foundation, songwriting, recording, and production. His collaboration with Swift helped shape the shimmering, reverb-heavy sound that distinguishes “august” from the more acoustic or folk-oriented moments elsewhere on Folklore.
