In the movie "Casablanca," what are three examples each of diegetic and non-diegetic sounds included by the filmmaker? Additionally, what effects do these sounds have on the film? Thank you for any assistance.

Diegetic sound refers to any sound presented as originated from source within the film's world, while non-diegetic sound comes from a source outside that world.

In the movie "Casablanca," examples of diegetic sounds include:

1. Dialogue between characters: When characters speak to each other, their voices are part of the film's world. 2. Sam playing "As Time Goes By" on the piano: The music is coming from within the world of the story as the characters listen to it in Rick's café. 3. Sound effects of the bustling market: Background noises like people talking, cars driving, and general street ambiance in the marketplace of Casablanca.

Non-diegetic sounds in "Casablanca" include:

1. Dramatic score: The film's orchestral music that underscores the emotional weight of a scene is non-diegetic as it is not heard by the characters, but it's meant for the audience's experience. 2. Narration: Any voice-over narration that provides context or commentary not heard by the characters. 3. Symbolic sounds: Sometimes sounds like a ticking clock or a heart beating are used to convey a concept like the passage of time or nervousness; these sounds are not actually present in the scene's space.

The effects of these sounds on the film:

The diegetic sounds help create a sense of realism within the film's world. They immerse the audience in the environment and help in the storytelling by making the space feel lived-in and authentic.

Non-diegetic sounds are used to manipulate the audience's emotional response. The score heightens the tension, romance, or danger at key moments in the narrative. They provide a layer of commentary or additional meaning to what is being shown on screen, often guiding the audience towards a specific reaction and enhancing the cinematic experience.

Extra: Diegetic and non-diegetic sounds are essential tools in a filmmaker's arsenal to tell their story. Diegetic sounds can also include elements like phones ringing, doors slamming, and glasses clinking. They help in world-building and give depth to the cinematic environment. Conversely, non-diegetic components like a film's score or sound effects added for dramatic purposes do not exist in the story world but are rather used to influence the viewer’s psychological and emotional experience.

The balance between diegetic and non-diegetic sound is crucial for the overall storytelling. For example, in a tense scene, a loud, non-diegetic score can build suspense, while the sudden silence or absence of music can pay off with a jump scare or a moment of revelation. Understanding the interplay between these types of sounds is key to appreciating how films like "Casablanca" create powerful and lasting impressions on their audiences.
