⭐ Sound ⭐

Sound is an important factor to any piece of film, be it a movie of a TV show. Though there are a lot of things accounted for an effective sound throughout any piece of film; and everything below is important to understand.

Diegetic and Non-Diegetic

Diegetic sound is 'realistic to what we see on screen. The source of this sound is visible on screen, and is involved with the narrative. A door slamming, sirens in the distance, or a phone ringing are basic examples of what diegetic sound is. More examples may include:

• Dialogue 
• Sounds created by objects 
• Music coming from instruments on screen
• Room tone and ambience (background noise)

Non-Diegetic sound is practically the opposite of diegetic sound. The source is not present within that narrative, nor is is supposed to be. This can only be heard by the audience alone. Examples are as follows:

• Music to set the mood
• Soundtrack or score
• Dramatic sound effects that do not fit with what is on screen
• Commentary

Terminology 

Non-Diegetic

• Title music: Theme tunes, usually used within the opening titles of a moving image series or movie

• Score/incidental music: Orchestral music, used to connote the tone/atmosphere

• Sound motifs: Sounds associated with certain characters; connoting that something good/bad is about to happen

• Sound effects: Used to create atmosphere 

• Voice over: Gives the viewer a better insight of the thoughts of a character (creating a bond between both the audience and the character), set the scene or progress the narrative

Diegetic

Synchronous sound: Sounds matching what is seen on screen

Sound effects: Realistic sounds matching the action on screen; creating realism or connoting atmosphere (gun shots, door opening/closing)

Dialogue: Characters speaking

Ambient sound: Natural background noise you would expect to hear if the scene were real. This is vital to creating realism
