like the ones otoya plays repeatedly, and his piece for the queen? idk if they were in the soundtrack, but i do have the complete cd-box, i'll check it out.
They were on the soundtrack. All three versions of the violin song. I don't totally get what you're asking so I'll just say to clear up, the songs played on violin are original pieces...they're not famous classical pieces. I don't know if you thought that but I just thought I'd clear it up.
