Which producer co-wrote Taylor Swift’s “august” and helped create its instrumental?

Jack Antonoff co-wrote and co-produced Taylor Swift’s “august.”

For the song, Antonoff created the instrumental first and sent it to Swift. She then wrote the lyrics quickly, describing the process as intuitive. Their collaboration produced the song’s shimmering guitars, layered textures, keyboards, strings, and expansive reverb.

Antonoff had already worked with Swift on songs from 1989, Reputation, and Lover before collaborating on Folklore. Their partnership continued across later Swift projects, making him one of her most prominent recurring creative collaborators.

Aaron Dessner is an important but different name in the Folklore story. He produced many tracks on the album and participated in its Grammy performance, but “august” is specifically credited to Swift and Antonoff as songwriters and producers, with Joe Alwyn later recognized as a co-producer.
