I did some research on what type of music is most effective with the horror genre and i found that orchestral music is really effective and has been used ever since this genre began but also synth-based music and industrial music, have been used in more modern times. Here is a good example which i found on youtube and i feel we could create something like this in garageband and add it into the scene where the boy is walking home. Gavin
