Sadness and Sorrow was composed by Toshio Masuda for the original Naruto anime, which premiered in 2002, and appears on the first Naruto Original Soundtrack released in 2003. It became the series' signature cue for bereavement, exile and childhood flashbacks, returning whenever the story slowed down for Haku, Zabuza, the Third Hokage and other losses. Clips and piano covers spread widely on YouTube and anime forums in the 2000s, and editors kept reusing it long after, so listeners now recognise the melody within seconds even outside the show.
