Moonlight Sonata

I remember being around 10 and asking my dad the name of Moonlight Sonata during a road trip; it really stuck in my head. I grew up in an tropical island and to me Moonlight Sonata sounded foreign, like the soundtrack for a movie set in a cold and foggy place like North France. I would picture a castle and a romantic but tragic story. Dracula-esq. But to be honest, other than Beethoven's 5, 7 & 9 symphonies and Vivaldi's seasons, I don't think could name much else.
