"The Great Thaw (Vuelie Reprise)" is a musical number written by Norwegian musician Frode Fjellheim and composed by Canadian score composer, Christophe Beck, with additional vocals by the Norwegian female choir Cantus, for the 2013 Disney animated film, Frozen.
The track plays in the moments where Anna begins to thaw, successfully recovering from the frozen heart curse that Elsa had accidentally struck her with. The two sisters then hug, with Anna saying that she sacrificed herself because she loves Elsa. After Olaf's revelation that love will thaw, Elsa realizes that since love is the most powerful feeling of all, it is the key to controlling her powers. This revelation manifests itself with Elsa releasing Arendelle from the eternal winter. The moment where Elsa begins to thaw the kingdom is where the reprise to "Vuelie" actually starts. The track ends with summer being restored, and Elsa bestowing a snow flurry on Olaf so that he doesn't melt in the heat.
Similarities with other tracks
As Elsa reconstructs Olaf at the end of the track, part of the main tune to "Do You Want to Build a Snowman?" plays.
On the soundtrack, instead of the silence that the track technically begins with, there is a slow, sad violin ensemble, which then transitions into the existing track.
