Harmony Hall

This spiralling song was the first single released by Vampire Weekend since "Unbelievers" was dropped in 2013. A 5-minute tune that retains the band's spring-like signature sound, it was written by frontman Ezra Koenig and produced by the singer with their usual collaborator Ariel Rechtshaid. Vampire Weekend's former multi-instrumentalist Rostam Batmanglij supplied additional production.

The song is about how feelings can change over time. It kicks off with Koenig declaring: We took a vow in summertime Now we find ourselves in late December I believe that New Year's Eve Will be the perfect time for their great surrender But they don't remember Koenig explained the lyric in a Beats 1 interview, saying: "There was something about taking a vow in summertime and now it's the end of the year, that there was like a feeling I related to."

The song title features in the first line of the chorus. And the stone walls of Harmony Hall bear witness The lyric likely refers to the undergraduate dormitory building of the same name situated at Ezra Koenig's Alma Mater of Columbia University.
