Today i am going to talk about sound techniques.

-Diegetic sound. Sound originating from a source in the scene, for example:
          -Voices of characters.
          -Sounds made by objects in a story.
          -Music represented as coming from instruments in the story space.

-Non-diegetic sound. Sound added in postproduction.
         -Narrators comentary.
         -Sound effects which is added for the dramatic effect.
         -Mood music

-Sound motif. A sound of piece of music associated with a character, place or theme. The sound motifs condition the audience emotionally for the intervention, arrival or actions of a particular character. The sound motifs can be very useful in the rough cut, where they help clarify the narrative functions of the characters and provide a sound association for those characters as we move through the story.

-Voiceover. Dialogue spoken by an unseen character over related images.

-Ambient sound. Background noise.
