"Et si" is a song by French popstar Shy'm, from her fourth album Caméléon. It was chosen to be the third single from Caméléon and the radio edit of the song (which features less prominent guitars, and a more uptempo chorus) was released to iTunes on 5 November 2012. "Et si" (which translates to English as "And If") is a midtempo pop song in which Shy'm questions whether her love will last forever. It is one of the more ballad-like songs on the album. The album version primarily features guitar and piano, while the radio edit strips away the guitar and includes more synths.
