A song can be part of the room or accompany it from outside the narrated world. Tarantino uses both possibilities and sometimes makes the boundary shift while the scene is still unfolding.
The difference depends on the source within the fiction
Diegetic music belongs to the world of the story: it may come from a radio, an instrument, a playback device or a singing voice. Extradiegetic music is presented as accompaniment for the viewer without a source recognised by the characters. The distinction does not depend on genre, volume, or whether the piece is a song or an orchestral composition.
In Reservoir Dogs, the broadcast from K-Billy provides a recognisable source for the song that Mr Blonde hears and dances to. The character acts on the musical environment, and his movement responds to it. By contrast, music that accompanies a title sequence does not need to exist as audible sound in the street or room where the action takes place.
The presence of a device does not automatically settle the whole scene either. A record player can be switched off and a song can continue over a change of location where it would no longer have physical reach. One has to pay attention to actions, transitions and reactions. The analysis becomes more precise when it identifies which clue supports the classification, rather than attributing all the music the audience hears to the characters.
Listening is also a character's action
In Pulp Fiction, Mia starts playing Girl, You’ll Be a Woman Soon and moves with the song. Her choice is part of what she is doing while Vincent is in another part of the house. The track is not just an external comment on her: it occupies her time, accompanies her behaviour and contributes to the separation between what each character is experiencing.
In Jackie Brown, listening to The Delfonics becomes a link between Jackie and Max. Music can remain in memory and reappear through another medium. The viewer recognises an emotional connection without the characters having to spell it out completely. The material source allows a preference to be shared, remembered and carried elsewhere.
Instruments introduce a variation. The piano in Minnie’s Haberdashery places the music within a tense gathering; the person playing shares space with those who are talking. In Django Unchained, the performance of Für Elise at Candyland belongs to a social practice that the characters can interrupt. These are not examples of an invisible orchestra that simply expresses the mood of the scene.
The sung voice can also be diegetic. Daisy performs Jim Jones at Botany Bay while accompanying herself on the guitar. The gesture takes time, draws attention and prompts an intervention from Ruth. The fact that the song is thematically significant does not remove it from the narrated world. Its symbolic meaning coexists with the concrete action of a person singing in front of others.
A source can remain off-screen and still be diegetic. Hearing someone play before the camera shows them does not temporarily turn their music into an external score: it may simply be spatial information that the image has not yet completed.
The boundary can expand without disappearing
A song that starts on a device can acquire, in the mix, a greater breadth than that of its source. The film then allows us to feel it both as part of the characters’ surroundings and as part of the editing structure. It is not always necessary to decide that one category cancels out the other. One can describe the shift from a visible source to a wider narrative function and note where it happens.
The radio in Tarantino’s films enables these shifts because it connects different places through the same broadcast. A presenter’s voice can continue while the image changes, creating a sense of simultaneity. However, that continuity does not mean every character is hearing exactly the same passage if the film does not establish it. The editing can use the broadcast for the audience as well as represent it inside the cars.
The reverse case is also useful: music that initially seems external may later be found to have a source within the image. That discovery retrospectively reorganises the listening experience. What seemed like the narrator’s decision is revealed as someone inside the scene’s choice. The surprise affects attribution of control: it changes who seems to have decided that that sound should be there.
The distinction also does not directly tell us anything about the filming. A diegetic song may have been added or adjusted in post-production, even though the fiction presents it as coming from a device. An actor may mime a performance that is later completed in recording. The question of who hears the music within the story is different from the question of how the sound was captured during production.
Paying attention to these differences makes it easier to understand why the same piece can produce intimacy, threat or irony. What matters is not only which song has been chosen, but who seems to choose it, who can stop it and who has to listen. Tarantino builds many of his power relations through these small actions. The music belongs to the director’s style and, when the scene shows it, also to his characters’ decisions.
