Did you check the credits at the end of the movie?
Here's the classical pieces listed in the credits:
8th Symphony in B minor Unfinished D759 - 1st Movement (Schubert)
Symphony #6 in B minor Pathétique' Op. 74 (Tchaikovsky)
Menuet: Allegro Ma Non Troppo from String Quartet in C major, Op. 64, No. 1 (Haydn)
Jesu, Joy of Man's Desiring by Bach is also listed, but I know it's not this piece of music you're looking for. The other ones I'm not completely familiar with. Try www.classical.com
. You can listen to one-minute samples of pretty much any piece of music you can find.
I'd like to see Johnny Depp direct a movie about Tim Burton directing a movie starring Johnny Depp, in which Johnny is directing a film about Danny Elfman, who is composing the music for a new Tim Burton film starring Johnny Depp.....playing Danny Elfman.
