Research and Planning: sound influences for teaser trailer

After looking into the sound aspect of my teaser tralier, I have decided to look at adding certain sound effects to build the tension, sounds like cars crashing and windows smashing is a heavy convention in films were panic is featured. Also I have looked at music from other zombie films and found lots of purcussion instuments have been used, I will take this into consideration when making the soundtrack for my teaser trailer. Also looking at existing trailers like 28 days later , 28 weeks later and resident evil 4&5 trailers I have found that the trailer is mainly based on sharp errie sounds and then music is played over a small action section of the trailer, then at the end the errie sound returns to finish off the trailer again leaving the audience with suspence.
