Background

Following the release of the Mr. Simple album in August 2011, Super Junior announced plans for album reissue called A-Cha along with its lead single of the same name on September 15.^[2] "A-Cha" was released on September 19, the same day as the reissue album's release.

Composition

"A-Cha" features the vocals of nine active members — Leeteuk, Heechul, Yesung, Sungmin, Shindong, Eunhyuk, Donghae, Ryeowook, and Kyuhyun. Kangin was away on mandatory military service.^[3]

The song is based on electrohouse and rock which separated it from the group's existing dance songs such as "Sorry, Sorry" and "Bonamana" that were dubbed as "SJ Funky."^[4] The song's melody was composed and arranged by Hitchiker. It was composed in the key of D major with the tempo of 125 beats per minute.^[5]

Its lyrics were penned by Kim Boo-min, narrating the song akin to Alonso Quijano of the Don Quixote novel, a character trying to hold on to his wavering lover.^[6]
