Sadness and Sorrow comes from the original Naruto anime, where it was composed by Toshiro Masuda as part of the series' early soundtrack. It became closely linked with the show's quieter, more emotional scenes, especially moments of loss, parting, and reflection for Naruto and his friends. As clips and anime music videos spread on YouTube, the piano theme travelled far beyond the show itself, and later short-form edits kept it alive. It remains popular because its simple, instantly recognisable melody conveys grief without words, making it a reliable choice for sad edits across fandoms.
