I love classical music, I play trumpet. I tend to nerd out a bit, so ignore that if you find it offensive. Psychology and physics are my mainstays if I must avoid playing my horn.
Very many things. Really, an absurd number of things. I hate anime in general but for some reason, I really love Studio Ghibli. I like tennis. Also, cooking things.
Impressionists and whole-tone composers. Debussy, Ravel, Satie, Janecek. I also happen to love Mahler and Bruckner. Shostakovich and Rachmaninov round it out. Prolific pianists like Chopin, Liszt, and Beethoven are acceptable too.
Everything by Stanley Kubrick, Christopher Nolan.
Hayao Miyazaki as well if he counts.
