Sakimoto stated in an interview included in a bonus disc of the collector's edition of the game that his favorite pieces from the soundtrack are the "world" themes in the outdoor areas, and that his overall favorite is "The Cerobi Steppe". Sakimoto created the music for the game based on the atmosphere of the game and the emotional changes of the characters, rather than the story, so that the music would not be affected by changes in the development of the game. "Clash on the Big Bridge" plays during the battle with Gilgamesh, as it did in Final Fantasy V. Of these, all but "Clash on the Big Bridge" are recurring pieces used in almost every Final Fantasy game. 1", "Chocobo ~FFXII Version~", and "Clash on the Big Bridge ~FFXII Version~". These tracks include "Final Fantasy ~FFXII Version~", "Victory Fanfare ~FFXII Version~", "Chocobo FFXII Arrange Ver. The soundtrack also includes pieces composed by Uematsu for previous Final Fantasy games, with new arrangements by Sakimoto.
However, he did attempt to ensure that his style would mesh with Uematsu's "Kiss Me Good-Bye" and the overall vision of the series. Sakimoto did not meet with Uematsu for direction on creating the soundtrack and tried to avoid copying Uematsu's style from previous Final Fantasy soundtracks.
Sakimoto experienced difficulty following in Uematsu's footsteps, but he decided to create a unique soundtrack in his own way, although he cites Uematsu as his biggest musical influence. Sakimoto was brought in to compose the soundtrack to the game by Yasumi Matsuno, the producer of the game, five months before the game was officially announced. She based her words for the song on "a scene of a new journey after good-bye", which was the sense she had gotten from Uematsu's melody, and was encouraged by Uematsu not to limit herself in her lyrics to what she thought the producers wanted. Aki was approached for the role three years before the release of the game. Uematsu noted that Aki's style of playing the keyboard while singing reminded him of his childhood idol, Elton John, which was one of the reasons he chose her. Hitoshi Sakimoto composed most of the game's soundtrack Nobuo Uematsu, following his departure from Square Enix in 2004, only contributed the theme song, " Kiss Me Good-Bye", sung by Angela Aki. Hitoshi Sakimoto was the lead composer of Final Fantasy XII The game's soundtrack was nominated for a British Academy of Film and Television Arts award for Best Original Score. The singles for the soundtrack were very well received by critics, who found them to be very enjoyable but short in duration, and the piano album was considered by reviewers to be one of the best in the series. However, several reviewers commented on "Kiss Me Good-bye", finding it to be one of the soundtrack's strongest areas. Common complaints about the album were the large number of filler tracks, which seemed to be uninspired and hurt the soundtrack as a whole. The soundtrack received mixed reviews from critics while several felt that it was an excellent album, others disagreed, finding it to be a good soundtrack but lacking in substance. An album of piano arrangements, titled Piano Collections Final Fantasy XII, was released by Square Enix in 2012. An abridged version of the latter piece, which originally accompanied a promotional video for the game, was included in the official soundtrack album. "Kiss Me Good-Bye" was released by Epic Records as a single in 2006, and Symphonic Poem "Hope", the complete music from the game's end credits, was released by Hats Unlimited in 2006.
Additionally, a promotional digital album titled The Best of Final Fantasy XII was released on the Japanese localization of iTunes for download only in 2006. A sampling of tracks from the soundtrack was released as an album entitled Selections from Final Fantasy XII Original Soundtrack, and was released in 2006 by Tofu Records. The Final Fantasy XII Original Soundtrack was released on four Compact Discs in 2006 by Aniplex.
Former regular series composer Nobuo Uematsu's only work for this game was " Kiss Me Good-Bye", the theme song sung by Angela Aki. Additional music was provided by Masaharu Iwata and Hayato Matsuo, who also orchestrated the opening and ending themes. The music of the video game Final Fantasy XII was composed primarily by Hitoshi Sakimoto.
