"Circle of Life" is the opening song of Disney's 1994 animated feature film The Lion King, composed by Elton John with lyrics by Tim Rice. It was performed by Carmen Twillie (female vocals) and Lebo M (opening Zulu vocals) as the film's opening song. Elton John also sang a pop version of it with the London Community Gospel Choir, which was included in the film's soundtrack and made into a music video.
As Mufasa himself explains later in the movie, the "Circle of Life" that the song refers to is the delicate cycle, the natural world (wildlife, ecosystem, environment, biodiversity etc.) and balance of nature (predators eat prey, predators become grass when they die, prey eat the grass). Scar's reign disrupts the Circle of Life, though it is restored when Simba defeats him. Likewise, a plot point in The Lion Guard is for Kion to learn how to properly protect the Circle of Life.
