Music of Xenoblade Chronicles 3

The music of Xenoblade Chronicles 3 consists of an unknown number of tracks, several of which have been officially released as of June 2022. Yasunori Mitsuda, ACE, Manami Kiyota, Kenji Hiramatsu, Mariam Abounnasr, and Yutaka Kunigo all contributed to composing for the game.

Significance in-universe
Music is relevant to the game's story and lore. The main characters Noah and Mio are off-seers, people who mourn those who died in battle, and both play a flute-like instrument (presumably) as a part of this practise. According to Mitsuda, the flute motif is meaningful to the music as a whole, and the instrument features prominently in the music of the reveal trailer.

Soundtrack
According to a tweet by Yasunori Mitsuda on the 30 July 2022, a soundtrack is planned for an unknown release date. (As of the time of the tweet, it has no announced title.)

Website BGM
The official Japanese website for Xenoblade 3 features a button labelled 'BGM' (an acronym commonly used in Japanese to signify 'background music') which, when pressed, plays music. Originally, it played A Life Sent On; after the Xenoblade 3 direct on 22 June 2022, The Weight of Life and Keves Battle were also added as options.

Xenoblade Notes
Xenoblade Note vol. 5, a blog post on Nintendo's Japanese website, included links to several unlisted YouTube videos of the game's music: A Life Sent On, The Weight of Life, and Keves Battle. Xenoblade Note vol. 8, posted later, featured an equivalent link to.

Twitter posts
The XenobladeJP twitter account, as well as the accounts of various regional Nintendo departments, posted various tracks from the game leading up to the game's release. These included the three in Xenoblade Note vol. 5, as well as You Will Know Our Names - Finale,, A Formidable Enemy, and A Step Away.
