【女性キー(+2)】空 / BE:FIRST【ピアノカラオケ・ガイドメロディ付】2025年度NHK全国学校音楽コンクール中学校の部課題曲

A piano karaoke arrangement featuring the song "Sora" (空) by BE:FIRST, specifically arranged in the +2 key signature optimized for female vocals. This version includes a guide melody over the original arrangement's piano accompaniment. The track is noted as being utilized for the 2025 NHK National School Music Competition for junior high school divisions, as the song is the designated piece for that year's competition.

An introductory measure has been added equal to one bar for counting purposes before the music commences. The audio source is intended for use in karaoke sessions or vocal practice (singing covers). Alternative versions of the track, including an instrumental-only version and a version at the original key, are referenced elsewhere.

The instrumental track is available for download across multiple keys, ranging from +6 to -5, through a dedicated online store for distribution.
