Sound Analysis: Nanny McPhee Returns (2010) trailer

A sound bridge is used. This occurs from 0:06-0:08. This non diegetic music continues until 0:19. a voice over is used throughout  to give the audience a basic understanding of the film and to pre-empt the camera shots. This directly engages the viewer and makes them feel more involved. The cousins are almost presented as a disequilibrium as there is no non diegetic sound at 0:19. The calm atmosphere is disrupted with the appearance of the children. The fast paced music parallels the action on the screen.When the children start causing trouble, there is more fast paced, less fairytale like music from 0:22-0:34. This is probably to represent the havoc being caused.
However, the non diegetic sound loses prominence at 0:27 when the diegetic sound becomes the focus. At 0:32, the sound is particularly effective because it becomes loud and has an echo effect. At 0:34, the sound effect of knocking is the most significant sound. This is then overshadowed by the use of loud and high pitched music from 0:35-0:37 in order to build tension. The comparative silence at 0:38 means that the declarative has more impact. The vast majority of the trailer uses non diegetic sound, voice overs and dialogue together. This makes the trailer seem more interesting and engages the audience, whilst also representing the mischievous nature of the children.

The absence of non diegetic sound (soundtracks and voice overs) at moments such as 1:14-1:15 makes what the characters say have more impact, and takes the audience back to a central focus. Breaks in the sound stop it from becoming too overwhelming for the senses. The sound effect of fairy dust is frequently used. The changes in soundtrack also help the audience to identify the mood of the shot(s). For example, from 1:49 onwards the mood is a lot happier and the soundtrack reflects this.

Overall effect/contribution
The overall contribution of sound is large because it helps reflect the mood of the movie, and brings to life the camera shots and editing.

The film is promoted as Nanny McPhee and the Big Bang in the UK.
