The score introduces several new themes interwoven throughout the film, including identities for the character Rose Tico, the interactions between Rey and Luke Skywalker on Ahch-To Island, and the Resistance's desperate escape from the First Order.The score also reprises numerous themes and motifs introduced in The Force Awakens, including those for the characters of Rey, Kylo Ren, Poe Dameron, and Snoke, as well as the March of the Resistance and The Jedi Steps. Themes introduced in the original trilogy return as well, including Luke's Theme, Leia's Theme, The Rebel Fanfare, and the Force Theme from A New Hope; Yoda's Theme, The Imperial March, and Han Solo and the Princess from The Empire Strikes Back; and, Luke and Leia and The Emperor's Theme from Return of the Jedi. Excerpts of the TIE Fighter Attack cue, first heard in A New Hope and reprised for Return of the Jedi, are also included. The Emperor's Theme is the only returning theme to not be included within the official soundtrack presentation; it occurs in the film when Snoke tortures Rey for information.The score briefly quotes Aquarela do Brasil by Ary Barroso in its Canto Bight track as a reference to the 1985 Terry Gilliam film Brazil. It also contains a brief quote of Williams's own theme for The Long Goodbye (co-composed by Johnny Mercer) during Finn and Rose's escape, although this was not included in the official soundtrack release. All tracks written by John Williams.
