girl on the train trailer analysis (need to finish)

conventions

tension music- the music is very low key but is a constant beat and has small pauses in specific parts to have emphasis on key pieces of dialogue, as the trailer goes on the back beat gradually gets stronger and louder as the tension and suspense is being built up and then stops when it gets to a defining point and completely puts the focus onto the line the character says . The music restarts as the title roles and slowly fades out with a beat.

editing

the editing it is time with the music so it changes scene , fades to black or jump cuts on the beat on the song. a lot of fades to black and dialogue still playing while it is black , this means it focuses the audience in on the important line and also reveals another small bit about the film but also more mystery.
