I'm a big fan of soundtracks - I'll admit, whether I've watched the film or not - and I can honestly say that this is one of my favourites. I am also a Twilight fan, of the books especially and I did thoroughly enjoy the movie too. I was wary about the soundtrack at first because I could almost hear how I wanted it to sound in my head as I read the books and was especially eager for Bella's lullaby to be perfect.
I wasn't disappointed. Carter Burwell captures it all - from the tenderness of Bella's Lullaby and The Lion Fell in love with the Lamb to the tension and curiosity of Phasination Phase(if music can evoke curiosity, then this track certainly does). The best parts are the ones that are filled with fighting, danger, fear and drama like Humans are Predators Too and The Ballet Studio.
I suppose I have to be honest and say that Bella's Lullaby, whilst a beautiful and subtly composed track with an original yet simple melody, is not exactly all I would have wanted from the lullaby described in Meyer's book. It somehow doesn't have the range or emotional impact I would have liked for the lullaby, despite being a brilliant track and brilliant recurring motif in the soundtrack. Still, it's a minor complaint and overall I can say that there are few soundtracks that underline the themes, emotions and even the visual aspects of a film better.
