In diegesis, the "narrator tells the story. The narrator presents the actions (and sometimes thoughts) of the characters to the readers or audience. Diegetic elements are part of the fictional world ("part of the story"), as opposed to non-diegetic elements which are stylistic elements of how the narrator tells the story ("part of the storytelling").
Diegesis (Greek διήγησις "narration") and "mimesis (Greek μίμησις "imitation") have been contrasted since "Plato's and "Aristotle's times. Mimesis shows rather than tells, by means of action that is enacted. Diegesis is the telling of a "story by a "narrator. The narrator may speak as a particular character, or may be the invisible narrator, or even the all-knowing narrator who speaks from "outside" in the form of commenting on the action or the characters.
In Book III of his "Republic (c. 373 BC), "Plato examines the "style" of "poetry" (the term includes "comedy, "tragedy, "epic and "lyric poetry): All types narrate events, he argues, but by differing means. He distinguishes between narration or report (diegesis) and imitation or representation ("mimesis). Tragedy and comedy, he goes on to explain, are wholly imitative types; the "dithyramb is wholly narrative; and their combination is found in "epic poetry. When reporting or narrating, "the poet is speaking in his own person; he never leads us to suppose that he is any one else"; when imitating, the poet produces an "assimilation of himself to another, either by the use of voice or gesture". In dramatic texts, the poet never speaks directly; in narrative texts, the poet speaks as him or herself.
In his "Poetics, the "ancient Greek "philosopher "Aristotle argues that kinds of "poetry" (the term includes "drama, "flute "music, and "lyre music for Aristotle) may be differentiated in three ways: according to their medium, according to their objects, and according to their mode or "manner" (section I); "For the medium being the same, and the objects the same, the poet may imitate by narration — in which case he can either take another personality as Homer does, or speak in his own person, unchanged — or he may present all his characters as living and moving before us" (section III).
In "filmmaking the term is used to name the story depicted on screen, as opposed to the story in "real time that the screen narrative is about. Diegesis may concern elements, such as characters, events, and things within the main or primary narrative. However, the author may include elements that are not intended for the primary narrative, such as stories within stories. Characters and events may be referred to elsewhere or in historical contexts and are therefore outside the main story; thus, they are presented in an extradiegetic situation.
For "narratologists all parts of narratives — characters, narrators, existents, actors — are characterized in terms of diegesis. For definitions of diegesis, one should consult Aristotle's "Poetics; "Gerard Genette's Narrative Discourse: An Essay in Method (Cornell University Press, 1980); or (for a readable introduction) H. Porter Abbott's The Cambridge Introduction to Narrative (Cambridge University Press 2002). In literature, discussions of diegesis tend to concern discourse/sjužet (in "Russian Formalism) (vs. story/"fabula).
Diegesis is multi-levelled in narrative fiction. Genette distinguishes between three "diegetic levels". The extradiegetic level (the level of the narrative's telling) is, according to Prince, "external to (not part of) any diegesis." One might think of this as what we commonly understand to be the narrator's level, the level at which exists a narrator who is not part of the story being told. The diegetic level or intradiegetic level is understood as the level of the characters, their thoughts and actions. The metadiegetic level or hypodiegetic level is that part of a diegesis that is embedded in another one and is often understood as a "story within a story, as when a diegetic narrator himself/herself tells a story.
The classical distinction between the diegetic mode and the mimetic mode relate to the difference between the epos (or "epic poetry) and drama. The "epos" relates stories by telling them through narration, while drama enacts stories through direct embodiment (showing). In terms of classical "poetics, the cinema is an epic form that utilizes dramatic elements; this is determined by the technologies of the camera and editing. Even in a spatially and temporally continuous scene (mimicking the theatrical situation, as it were), the camera chooses where to look for us. In a similar way, editing causes us to jump from one place (and/or time) to another, whether it be somewhere else in the room, or across town. This jump is a form of narration; it is as if a narrator whispers to us: "meanwhile, on the other side of the forest". It is for this reason that the "story-world" in cinema is referred to as "diegetic"; elements that belong to the film's narrative world are diegetic elements. This is why, in the cinema, we may refer to the film's diegetic world.
"Diegetic", in the cinema, typically refers to the internal world created by the story that the characters themselves experience and encounter: the narrative "space" that includes all the parts of the story, both those that are and those that are not actually shown on the screen (such as events that have led up to the present action; people who are being talked about; or events that are presumed to have happened elsewhere or at a different time).
Thus, elements of a film can be "diegetic" or "non-diegetic". These terms are most commonly used in reference to sound in a film, but can apply to other elements. For example, an insert shot that depicts something that is neither taking place in the world of the film, nor is seen, imagined, or thought by a character, is a "non-diegetic insert. Titles, subtitles, and "voice-over narration (with some exceptions) are also non-diegetic.
"Sound in films is the background music that cannot be heard by the characters in the movie. This music is termed non-diegetic or extradiegetic. An example of this is in "Rocky, where "Bill Conti's ""Gonna Fly Now" plays non-diegetically as Rocky makes his way through his training regimen finishing on the top steps of the "Philadelphia Museum of Art with his hands raised in the air.
If the characters in the film can (or could) hear the music the audience hears, then that music is called diegetic. It is also called "source music by professionals in the industry. It is said to be within the narrative sphere of the film. For instance, if a character in the film is playing a piano, or turns on a CD player, the resulting sound is diegetic. The cantina band sequence in the original "Star Wars is an example of diegetic music in film, with the band playing instruments and swaying to the beat, as patrons are heard reacting to the second piece the band plays.
Songs are commonly used in various film sequences to serve different purposes. They can be used to link scenes in the story where a character progresses through various stages toward a final goal. If it is synchronized with the action, as in the "Good Morning" dance sequence from "Singin' in the Rain, it is said to be "Mickey mousing.
This distinction may be toyed with in order to break the "fourth wall. In the "Archer episode ""Sea Tunt Part 1", Cheryl begins to hear music that would otherwise seem to be non-diegetic. She even comments: "Just ignore it; it's non-diegetic." In the "Muppet Show segments "Pigs In Space" and "Veterinarian's Hospital", the characters often hear the concluding voiceover and look around looking for its source.
There are other varying dimensions of diegesis in film sound, for example, metadiegetic sound, which are sounds imagined by a character within the film, such as memories, hallucinatory sounds, and distorted perspectives. Another notable condition of diegesis is cross-over diegesis, which is explored in the book Primeval Cinema - An Audiovisual Philosophy by Danny Hahn, in which he describes it as "blending/transforming a sound or piece of music from one spectrum of diegesis to another – from diegetic to non-diegetic space". The sci-film "2BR02B: To Be or Naught to Be is an example of cross-over diegetic music in film, with Schubert's "Ave Maria playing over separate shot sequences as non-diegetic music, but then later showing it to come from a gramophone in a hospital waiting room. The music also becomes diegetic with the assistance of audio engineering techniques, having its reverberation undergo change to match the room's characteristics and indicate a spatial location from the surround speakers. Even though Ave Maria reappears extensively as diegetic music, its inclusion was treated as non-diegetic by the film-makers, the song being a bespoke recording by soprano Imogen Coward to match the film's tone, and the film being edited to her recording. The recording itself was timed to include a layer of narrative commentary for audiences familiar with the German lyrics.
In "musical theatre, as in film, the term "diegesis" refers to the context of a musical number in a work's theatrical narrative. In typical operas or operettas, musical numbers are non-diegetic; characters are not aware that they are singing. In contrast, when a song occurs literally in the plot, the number is considered diegetic. Diegetic numbers are often present in "backstage musicals.
For example, in "The Sound of Music, the song ""Edelweiss" is diegetic, since the character (Captain von Trapp) is aware that he is singing. In ""Do-Re-Mi" the character Maria is using the song to teach the children how to sing, so this song is also diegetic. In contrast, the song ""How Do You Solve A Problem Like Maria?" is non-diegetic, since the musical material is external to the narrative.
In both the 1936 and the 1951 film versions of "Show Boat, as well as in the original stage version, the song "Bill" is diegetic. The character "Julie LaVerne sings it during a rehearsal in a nightclub. A solo piano (played onscreen) accompanies her, and the film's offscreen orchestra (presumably not heard by the characters) sneaks in for the second verse of the song. Julie's other song in the film, ""Can't Help Lovin' Dat Man", is also diegetic. In the 1936 film, it is supposed to be an old folk song known only to blacks; in the 1951 film, it is merely a song that Julie knows; however, she and the captain's daughter Magnolia are fully aware that Julie is singing. When Julie, Queenie, and the black chorus sing the second chorus of the song in the 1936 version, they are presumably unaware of any orchestral accompaniment, but in the 1951 film, when Magnolia sings and dances this same chorus, she does so to the accompaniment of two deckhands on the boat playing a banjo and a harmonica. Two other songs in the 1936 Show Boat are also diegetic: "Goodbye My Lady Love" (sung by the comic dancers Ellie and Frank), and ""After the Ball", sung by Magnolia. Both are "interpolated into the film, and both are performed in the same nightclub in which Julie sings Bill.
In the television series "Buffy the Vampire Slayer, the episode entitled ""Once More, with Feeling" toys with the distinction between diegetic and non-diegetic musical numbers. In this episode, "the Buffy characters find themselves compelled to burst into song in the style of a "musical. The audience is led to assume that this is a "musical episode", in which the characters are unaware that they are singing. It becomes clear that the characters are all too aware of their musical interludes, and that determining the supernatural causes of the singing is the focus of the episode's story.
In video games "diegesis" comprises the narrative game world, its characters, objects and actions which can be classified as "intra-diegetic", by both being part of the narration and not breaking the "fourth wall. Status icons, menu bars and other UI which are not part of the game world itself can be considered as "extra-diegetic"; a game character does not know about them even though for the player they may present crucial information. A noted example of a diegetic interface in video games is that of the "Dead Space series, in which the player-character is equipped with an advanced survival suit that projects holographic images to the character within the game's rendering engine that also serve as the game's user-interface to the player to show weapon selection, inventory management, and special actions that can be taken.
