Hello (Aya Ueto song)

"Hello" is a song recorded by Japanese singer Aya Ueto, from her debut studio album, Ayaueto. It was released as the album's third and final single by Flight Master on February 26, 2003. The single was released in two versions, a standard edition and a limited edition, each with differing cover art. The first pressing of the limited edition also featured different artwork. The limited edition included a bonus DVD featuring the music video for "Hello". The "Symphony Modulation Style" remix of the song was used in commercials for Lotte ice cream Soh, starring Ueto herself.

Background
"Hello" was written, composed, arranged and produced by T2ya, marking his third consecutive collaboration with Ueto. CDJournal described the song as a "lyrical and melancholy ballad". "Hello" is composed in the key of A-flat major and set to a tempo of 84 beats per minute. Ueto's vocals span from B♭3 to C♯5. Initially, "Ambition", the leading track on Ayaueto, was set to be released as the third single off the album. However, Ueto insisted on "Hello" instead. "Hello" was recorded after Ueto had wrapped filming for Azumi, and right before Ueto started filming the drama series Kōkō Kyōshi (2003).
