Game theme song
The release specifications of "AIR" included "Tori no Uta" as the theme song. Lia was responsible for vocals, Key handled lyric crediting, and Shinji Orito and Kazuya Takase handled melody composition and arrangement respectively. Composer and arrangement could not be combined into the same position.
The version in the original soundtrack
The third track of the first album "AIR Original SoundTrack," released on September 27, 2002, contains the complete track; The second album also has a short version and an off vocal version. Hearing the opening sequence version doesn't mean the full song itself only has that segment.
A song with the same original soundtrack
The original soundtrack also includes vocal tracks such as "Blue Sky" and "Farewell Song," which together form the album with game BGM. The song title, the record containing the track, and the specific version together form reliable source identification information.

The 2025 Night Sakura adaptation
The 2025 track of "Passage of the Seasons" is titled "Sakura at Night," performed by Lia and arranged by Akki. Taisuke Takashi's production diary describes it as a seasonal adaptation that transforms summer songs into a night cherry blossom atmosphere.
The origins of recording in Los Angeles
Lia recalled that she originally helped Key contact the Los Angeles studio, and later, at Kazuya Takase's invitation, recorded the song in place of the singer who couldn't attend.
Starting from the chorus
Orito once received feedback that the chorus at the end of "Kanon" was not distinct enough, so when writing "Tori no Uta," he started with the chorus.
Audition recording and singer selection
According to Zhe Hu's review, the quality of the trial recordings Lia sent led to her being chosen as a singer.
Dissemination and commissioning after issuance
Shinji Orito recalls that it took about two or three years after its release to gradually feel the widespread response to "Bird Poem," and player covers kept it spread. Later, external music commissions often encouraged him to write works with the unique style of this piece.
Early studio recording background
Lia recalled in 2018 that the initial recordings for "Song of the Bird," "Blue Sky," and "Farewell Song" were done at Paramount Studios in Los Angeles, requiring a large amount of vocal material to be recorded within two days.
