Audio problem: In the scene where Victor plays the piano for the first time in the movie, we hear him playing long, sustained notes, which obviously need to be played with a pedal down. However, he doesn't use the sustain pedal. What's more strange is, the piano does not even have a sustain pedal.
Answer: A search on Google for sheet music just shows the titles of the tunes to be how they are listed on the soundtrack: Victor's Piano Solo, or Corpse Bride (Main Theme), or The Piano Duet. A web site (http://www.bluntinstrument.org.uk) suggests that "Victor's Piano Solo" appears to ape the famous moody first movement of Beethoven's 'Moonlight' piano sonata.
