Film Language - Sound

In my most recent lesson, i learned a range of sound techniques and information that would be extremely useful in the production of my Thriller movie.
Sound has been one of the biggest developments in the cinema and movie industry, and add emotion, and sense to films.

• On-Screen sound: Sound coming from objects or people on the screen. Eg: If you can see a radio on the screen, and the radio is playing music.

• Off-Screen sound: Sound that can be heard by objects off of the screen. Eg: The audience can hear a radio playing but can't see the radio on screen.

• Diegetic sound: Sound that the actors, as well as the audience can hear. For instance, a doorbell rings in a scene, so the actors and the audience can both hear it.

• Non-Diegetic sound: Sound that only the audience/viewers can hear, that isn't part of the film/scene. For example: a music clip ''over the top'' of a scene, like a theme tune, to create emotion from the audience.
• Sound Bridges: A piece of music whether it be diegetic or non-diegetic, that continues from one shot to the next.
• Parallel sound: Sound that is complimentary to the scene/sound that makes sense to the scene. Eg:Children having fun on the beach, so the producer may play happy music, and clips of laughter and splashing.
• Contrapuntal sound: Music that doesn't fit the scene. For example, the film 'Insidious' plays happy music on the radio whenever something scary/bad is about to happen.
