Canon's Death

"Canon" has only eight chords from beginning to end. The first part is soothing, derived from the melancholy in memory; the second part is distant and high, derived from longing; the third part has the greatest emotional fluctuations, almost crazy at the beginning, and then slowly softens, gradually slows down, and fades away. The entire song expresses the great sadness and longing for the passing of a lover, commemorating the love that lasts until death. There are also related articles on the Internet describing the story of "Canon", but I don't think there are any more gripping than this one.
