Sound Research

Lightning Bug

• The first eight seconds of the trailer consists of a classical piano tune which is mainly known to create an equilibrium as the sound of the piano is played in a calm melody, but the trailer actually starts with a thudding base sound effect which already indicates that there is some sort of interruption within the calmness of the piano music which could be a hint that there is something off key a midst the serenity that appears to be present in the film.
• A disequilibrium is created by the static sound which starts at around 0:13 and the disjointed snippets of sound which suggests that the same thing happens in the film (Todorov) with the disequilibrium. 
• The silence that occurs when the female actress uses dialogue, diegetic sound, and says "Earl did a bad thing", it creates an enigma (Barthe's enigma code) which will make the viewer more enticed when watching the trailer which could encourage them to want to watch the movie more. 
• The music which follows this quote is electronic/rock style music and this creates quite an eerie atmosphere about the trailer. This also conforms to the stereotype of typical psychological drama style music.
• The part where one of the actresses says the word "movies" is quite chilling, which could suggest quite a chilling side to the film which could make the viewer even more interested in the film as it seems to offer variety.
•  An further equilibrium is created at around 1:07 when the music changes to a non diegetic guitar piece which is featured mostly in romantic films and the diegetic sound of the girl saying "are you gonna kiss me?" creates some sort of enigma as to where the relationship of the boy and girl is headed.
• Humour is also thrown into the trailer, again showing that the film offers variety and the diegetic sound of dialogue says "sexy bitches are my favourite kind of bitches."
• In certain places there are diegetic sound effects like glass smashing and crying and this delivers a sense of passion and makes the trailer have a sense of thrill to it which makes it more than just a drama and makes it into the psychological drama that it is; the abruptness creates this feeling.
• When watching towards the end of the trailer, the last 20 seconds, the music is echoing and this sounds like music being played backwards almost, which creates a sense of distortion. The scream at the end is followed by the diegetic speech of the actor saying "is that scary enough for you?" in an echoing type of way and this makes it sound a lot more scary, which conforms to the slight scare factor that is present in some psychological dramas.
