Former regular series composer Nobuo Uematsu's only work for this game was "Kiss Me Good-Bye", the theme song sung by Angela Aki.

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.

An abridged version of the latter piece, which originally accompanied a promotional video for the game, was included in the official soundtrack album.

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.

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.

[1] 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.

[4] The soundtrack also includes pieces composed by Uematsu for previous Final Fantasy games, with new arrangements by Sakimoto.

[8] Additionally, a promotional digital album titled The Best of Final Fantasy XII was released on the Japanese localization of iTunes for download only on March 15 the same year.

The album contains 11 tracks handpicked by Hitoshi Sakimoto, including versions of "Theme of Final Fantasy XII" and "Chocobo FFXII Arrange Ver.

[18] Ormond based many of the changes in theme or mood of his arrangements off of where the pieces were used in the original game, attempting to highlight the perspectives of different characters or ideas from the scenes they were played in.

[21] Kiss Me Good-Bye is the theme song of Final Fantasy XII, and is the third Japanese single by Angela Aki.

The only vocal piece in the game, it was set to tunes composed by Nobuo Uematsu, arranged by Kenichiro Fukui and produced by Motoki Matsuoka.

[24] The release was seen by critics as an excellent single, with Gann feeling that both the Final Fantasy XII and non-game tracks held their weight equally.

[22] Symphonic Poem "Hope" (交響詩「希望」, Kōkyōshi "Kibō") is a single released by violinist Taro Hakase and is the full version of the game's ending credits music.

A shorter edit blending the first, second and fifth movements of the symphonic poem was used in a promotional video for the game, and appears as a single track in the official soundtrack release.

[25] Hope was found by critics to be an enjoyable single, though at only 9 minutes long, Gann felt he could have "gotten by without it", although he said that for other listeners, their "collection may not be complete without this little gem".

[28] The Eminence Symphony Orchestra performed "Victory Fanfare", "Clan Headquarters", and "Penelo's Theme" at the three "Passion" concerts held in Australia and Singapore in December 2006.
