Well once you get your score, you need to go through it and analyse it in quite a lot of detail, which is where the study guide and my teacher's notes helped me a lot. For example, there is masses you can say about the first bar, let alone the first movement. The whole thing seems to be based on the use of the tritone, movement by step and the use of the third and some other things I can't remember! Either way, it would be a good idea to go through and work out where he uses the motif heard in the first bar, since it comes up many times! Also it's "relations", like the trombone part when they first enter in the first movement (not sure of the bar, but it's just over the page of 1a)
work out structure, what sort of harmony, how it relates to the story (learn and research that too) and the differences in the music between magical creatures and human creatures.
Make sure your score is the one they recommend, since if you have a different one then the page references in the study guide won't match up.
I'll add you to msn then you can pester me all you want, like I pestered my teachers! Nat said she'd help too, I think?
