My absolute favorite classical music piece. Although it's called the "Devil's" Trill Sonata, I can find so much of what I assume it means to be human. The internal struggle that plays out throughout the piece is like a person trying to find a reason to be happy, trying to find a reason for their struggles, or trying to find some closure in life. The piece modulates through so many emotions that I felt throughout depression and anxiety, but ultimately ends with a tone of finality, which I find very comforting. Although I'm healthy, now, I still listen to the piece religiously, albeit due to how human the piece feels to me and the sense of closure and release I get throughout the piece and in the end. I love to listen to while looking back on all my worries, struggles, and anxiety, eventually letting everything vent as the song ends and the Trill sounds. This is a great piece.
