"Reflection" is a song written and produced by Matthew Wilder and David Zippel for the soundtrack of Disney's 1998 animated film Mulan. In the film, the song is performed by Filipina singer and actress Lea Salonga as Fa Mulan. An accompanying music video for "Reflection" was included as a bonus to the Disney Gold Classic Collection DVD release of the film in 1998.
A single version of the song was recorded by American singer Christina Aguilera and became her debut single. She was 17 at the time it was released. The single's commercial success funded Aguilera's debut album from RCA, in addition to gaining her credibility amongst established writers and producers. Releases of the single were limited, which resulted in the track charting only on the Billboard Adult Contemporary chart, at number nineteen. An accompanying music video for the song was included on the DVD release of Mulan. Aguilera has performed the track on four televised performances, including at the CBS This Morning show, which saw her gain the attention of songwriter Diane Warren.
