I'm not the GP but I can recommend Bach's Partita in D minor, said to have been composed after returning from travel to find that his wife had died and been buried in his absence. https://youtu.be/VfwVim0EybY https://youtu.be/VfwVim0EybY Brahms said of it: "On one stave, for a small instrument, the man writes a whole world of the deepest thoughts and most powerful feelings. If I imagined that I could have created, even conceived the piece, I am quite certain that the excess of excitement and earth-shattering experience would have driven me out of my mind."
