Is It Tough Being a Friend? Volume 5

You may have noticed that in every audiovisual work, characters seem to have music playing in their heads at all times. It's not music playing on a radio in their car and they aren't at a concert. It's not songs they've heard. Not even classical tunes they’ve listened to. These are tunes that seem to just come out of nowhere, off the top of the character's head.

This technique is used because it makes you sympathize with a character's emotions. Without this music, you might not be able to connect with characters and feel their emotions quite as easily.

When music is used in movies and TV shows, there's two types: in-universe music the characters hear and music that the in-universe characters don't hear, because it's for the audience only. The first type is Source Music, aka "diegetic music", which is music you hear that comes from an in-universe source, such as the character's car radio as they're driving, a band at a bar, a street musician outside, or an instrument the character is playing.

If music is shown in one character's perspective, but then the perspective switches to another character who can't hear the music, that's Sudden Soundtrack Stop.

The pieces that are most closely tied to characters or events are Leitmotifs. If music is meant to make us think of a certain character's name, that's Fanfare.

Specific instruments and Standard Snippets are used to create a Mood Motif.

Usage of background music dates back to pre-antique times. For an example, classic Greek plays had usually music in the background.

Background music is a staple trope in some media such as films and video games. The usage of background music in these types of media is so omnipresent that its absence is often more notable than its presence.

For further exploration of this topic, listen to Anna Russell's "The Ring of the Nibelungs (An Analysis)".

This page lists lampshades of the phenomenon, such as when characters hear the background music, often Played for Laughs; straight examples are too many to count. For subversions, see Left the Background Music On. For aversions, see Reality Has No Soundtrack.

Compare Mickey Mousing, for when music that is meant to set the mood is actually being played by a character in-universe.

Comic Strips

  • The Far Side has several gags where characters can hear the background music:
    • One featured a shot of Tonto knocking on an outhouse door, whispering, "Kemosabe, hurry up, the music's starting!"
    • A group of cowboys at camp looking around: "There it goes again — whenever we settle in for the night, that harmonica starts up!"
    • A gal standing in the aftermath of a huge bar brawl recounts it to the police: "So this little sailor dude whips out a can of spinach, this crazy music starts playin', and... well, just look at the place!"

Live-Action TV

  • Young Sheldon: Discussed in "A German Folk Song and an Actual Adult". When Sheldon recaps Beverly Hills, 90210 for Missy, she notes that he's omitting the subtext of each scene because he can't tell social cues. Missy tells him to pay attention to the music, which informs what the characters are actually thinking. Later, when Mary tells Brenda that she's fine, adult Sheldon points to the viewers that the music actually means she's not fine.
