When Harry Manfredini began working on the musical score, the decision was made to only play music when the killer was actually present so as to not "manipulate the audience". Manfredini pointed out the lack of music for certain scenes: "There's a scene where one of the girls ... is setting up the archery area ... One of the guys shoots an arrow into the target and just misses her. It's a huge scare, but if you notice, there's no music. That was a choice." Manfredini also noted that when something was going to happen, the music would cut off so that the audience would relax a bit, and the scare would be that much more effective.
