Norwegian soprano Sissel Kyrkjebø performed the haunting, wordless vocals that are woven throughout James Horner's instrumental score in the 1997 film Titanic. Although Celine Dion sang the hit end-credits song, Sissel's ethereal voice provided the signature emotional sound within the movie itself.
