I'm working on a piece of fanfiction, and I'm hoping someone here can help me out a bit.
The main character in my piece has been severely traumatized, repeatedly sexually abused, manipulated, and nearly killed over the course of the story, and has had to repress his emotions to the best of his ability for most of the story. In the final chapter, in the aftermath, the character takes an opportunity to let some of his trauma out; he is a fairly skilled, classically trained pianist in canon, and he is going to play a song to passionately express his anguish. Unfortunately, I don't know much about piano myself.
I tried browsing some piano midis on this site, and sampled some Chopin, Schubert, Schumann, and Tchaicovsky, among others. I selected a few that may be serviceable, but I couldn't escape the feeling that I could still find something better. Although after about an hour and a half of this, I realized I was putting a rediculous amount of time into something that's going to ultimately take up two paragraphs at most.
I don't know much helpful terminology, but ideally the song should be something loud and expressive that sounds suitably tormented, something that would probably require him to really exert himself to play. While not absolutely neccessary, references to birds, butterflies, spiders, or being trapped would tie in thematically really well.
The story is set in modern-day Japan, although I believe the town itself is fictional. The character in question was raised in France until age 14, and is currently 17 years old.
