One of William's big efforts in 1993, the other one being Schindler's List, but was strange enough not even nominated for an Academy Award. Go figure... Jurassic Park is a vintage John William's score with a big orchestral sound; bold brass, dramatic strings and choir. Two themes dominates the music. One fanfare like brass theme, heard in all it's glory in cues like "Journey to the Island" (used for the first time in the film when the chopper approaches the island) and "End Credits", and another more grandiose, slow, but powerful theme, for the dinosaurs. This is the theme heard in the film when we see those big creatures for the very first time. There are also some minor motifs, like a terrifying atonal one for the raptors.
One could say that this soundtrack is divided into two different parts. The first half of the album is dedicated to the wonder and awe we feel for these animals, and the, more happy, part of the film, i.e. before everything goes completely out of hands. That's the second part, which has more action and suspense music. Now, I really don't like this music. It's terrific action music, so it's not that, but I can't listen to it without getting all nervous, uneasy and tensed. I suppose that proves the music is really great at doing what it's supposed to do, but I think it's hard listening to. Perhaps this has something to do with the fact that a lot of the music is very atonal, too... I don't know.
But I really, really like the more adventurous cues, like "Journey to the Island", "Welcome to Jurassic Park" and "High-Wire Stunts", and the more soft, tender parts, like "Hatching Baby Raptor" and the wonderful "My Friend, the Brachiosaurus", a very nice cue, with a warm, slow theme for the sick Brachiosaurus. "Dennis Steals the Embryo" is also a very good track, with, what I would like to call "sneak music". And then there's the opening music; a short track, just 30 seconds, with a very dark and dramatic choir, shakuhachi and powerful percussion (sounds like a trimmed timpani, or something...).
