"What Makes You Beautiful" is a song by the English-Irish boy band One Direction. It served as their debut single and lead single from their debut studio album, Up All Night (2011). Written by Savan Kotecha and its producers, Rami Yacoub and Carl Falk, the song was released by Syco Records on 11 September 2011. After recording it at Cosmos Studios and Kinglet Studios in Stockholm, Sweden, the band felt relieved to have a song that they were happy to release as their first single. The track is an uptempo song which interpolates pop genres teen pop, power pop and pop rock. It features a prominent guitar-based chorus and riff, and the middle eight consists of a "na na na" hook.
