Choosing music for the opening

we looked at some different tracks that were non copyright that we could freely download. we wanted something eerie and spooky sounding, something a little twinkly and creepy. we listened as a group to a few clips and settled on one perticular one, which we have used as the background track to the whole opening. we cut it and changed parts, slowed it down by 10% so it was slightly lower pitched and a bit slower, so it is deeper and darker . we also re positioned the peak of the music so that it fit with the peak of the tension in the film.
